I live next to a State Park. It sounded really cool when I bought the house. No neighbors! Privacy! There is a trail accessible from my properly that goes into some woods, which you only want to be in during the Fall / Spring because the ticks and chiggers are intense.
The biggest issue with sharing a border with the state is the fence line. Technically it's on them to maintain. The woods are filled with mostly 200 foot trees. They exist right up to my property and fall every year during big storms. There goes the fence line. I have dogs so the fence is important. Otherwise they run out into the woods that have licensed bow-hunting during the Winter.
In practice its impossible to get the fence fixed. You are working through layers of bureaucracy and mismanagement. There is no vested interest from a parks service to work well with hundreds of neighbors individually. I'd build fence lines myself, and could easily pay for it, but it's the upkeep of those fences that would be difficult because so many trees (really, it's every year) fall down from their side.
My main point is that sharing a properly line with the government is more like sharing a properly line with nobody. You may as well own that land. Don't expect any upkeep and go in with eyes open.
Hey, I mean this in as kind a way as possible, but I actually don’t think the government should pay for the fence line!
If you wouldn’t even pay for it yourself, as pretty much the sole beneficiary and someone who could afford it but would rather the money go elsewhere, why would it make sense for other taxpayers to pay for it?
Isn’t the premise of “you may as well own that land” the entire appeal of living next to public land anyway?
My family used to live next to state land. The state can be very pissy about its land. If the fence line is on the state land, which it almost certainly is barring a surveying error when it was put up, it is entirely possible that if he fixed it, he would actually get in trouble with the state. Hopefully not actual legal trouble... but only hopefully, certainly not a "oh they would never bother". Oh they most certainly do sometimes decide to bother about the most random things.
My default presumption, without checking with them directly, is not only that it would not be allowed, but that this is also very much not a "better to ask forgiveness than permission" situation either. Even just asking the question can draw attention from them you may not want.
The ready accessibility of the land is advantageous in some ways, but as neighbors the state can be quite nasty. Your other neighbors don't tend to have anywhere near the regulatory firepower to make sure you comply with what they want.
I think they’re suggesting building their own fence on their own property and eating the cost (as the sole beneficiary) of maintaining it through tree falls.
Nope (though it does depend). I’ve been through several trees falling from storms.
Unless negligence is involve (like an arborist being hired to condemn a tree), they’re generally considered and act of god. They’re the responsibility of the property they fall onto.
So, in the case of OP, the situation is unfortunate, but it’s on him to maintain his properties and his fence lines within his properties. It’s convenient the state has a fence along part of his property, but it’s not their responsibility to fix it for adjacent lots.
If they are aware of a dangerous situation (diseased trees), and don’t do something about it, they are definitely on the hook for property damage caused by that negligence.
It would boil down to their degree of plausible deniability, ‘state priviledge’, and the specifics of the law and precedent in their state of course.
I recently learned at least here in Germany it's not. Because larger trees are protected, you're generally not allowed to remove them even if they are close to another property. When they fall, it's considered force of nature and you won't be blamed. Unless, of course, the tree wasn't healthy in the first place and would be considered a danger.
How that works out in practice is basically you as the owner of the tree have to document it's healthy each year. Then, if it falls and you can prove it was healthy you're fine. Hopefully neighbors insurance pays. If you didn't document the health of the tree, your neighbor can press charges and you (or your insurance) have to pay.
nope. live in the forest, take care of yourself. a 250' sitka spruce fell from my neighbor's property onto the roof of my detached garage. it cost over 10k to fix it. the neighbor was not liable; it was covered by insurance
Fences are expensive. Firewood really isn't unless you're silly enough to spend money on the guys who come out and stack it for you for $600 a full cord. Awhile back I was getting 13 loggers cords for $1000, delivered, with the only caveat I had to cut and split and stack it myself. Upshot: I got to cancel my gym membership for the summer because that's a lot of work.
Fences can be made out of the tree that fell. Even post holes are optional. Only thing you need to pay for is some cheap wire mesh, and that may be reusable for repairs.
> If the fence line is on the state land, which it almost certainly is barring a surveying error when it was put up, it is entirely possible that if he fixed it, he would actually get in trouble with the state
Trying to maintain the state’s fence is not a good idea.
You would build your own fence on your side of the property set back by a couple feet.
> If the fence line is on the state land, which it almost certainly is barring a surveying error when it was put up, it is entirely possible that if he fixed it, he would actually get in trouble with the state.
Oh, the joys of living in a place with actual rule of law.
Here in my 3rd world country, people are free to annex land demarcated for streets that adjoin their property, without any real consequences, as long as it is not meant to be a major street.
I'd also assume the fence is on state land if its theirs to maintain. That doesn't stop someone from putting up their own fence on their side of the property line though.
You couldn't integrate it into theirs, so you'd be looking at having to fence in the entire space you want the dogs in because the gap you'd leave would have to be big enough for a dog.
Which is hardly the end of the world, but it can definitely grind the gears to be spending thousands when you could fix the problem for several hundreds, if not perhaps several tens, of dollars if they wouldn't be assholes about it. But I would absolutely advise anyone in that situation to spend the thousands and not bank on the state not being assholes about it.
I can also add that you can't even be sure that if you got away with it for years that you will continue to get away with it. The particular issue that my father got into a bit of hassle with the state about is that he accidentally put a pole barn across the state line. Didn't mean to, but he misread the survey markers. Fortunately, they let him remediate it at his expense without pursuing the matter any further legally... but it means they did, after several years of it being there, come through a with a survey team and verify that nobody on the border was crossing into their land, and anything they found they made the residents fix no matter how many years the deviation had been there. All the laws about such thing between two citizens mean nothing to the state.
> You couldn't integrate it into theirs, so you'd be looking at having to fence in the entire space you want the dogs in because the gap you'd leave would have to be big enough for a dog.
These properties only border public land on one side.
If someone is trying to fence their dogs into their property, it’s implied that they’re already fencing every other part of the property. They would be completing it with a back section.
I read the rest if the post and it makes no sense. The father story is non-sequitur, and this can only be interpreted as the poster not knowing how fences work: "you'd be looking at having to fence in the entire space you want the dogs in because the gap you'd leave would have to be big enough for a dog."
In the US, if a neighbor's tree falls on your house, they are likely only liable if it was due to negligence. I don't see how the state could possibly be liable for a tree on public land falling on someone's fence. Why would tax payers want to foot that bill?
Pretty much my exact thoughts as well. Heaven forbid a property owning pet owner be responsible for protecting their pets on their property. WTF has this world come to?
It's very common to build a fence on your own land, even if your neighbors have a fence?
Like my neighbors have a fence, I have a fence, there is like a 1' alley in between them, everything is on the respective owner's land, and that would definitely work even if your neighbor is the government.
If fence integrity is important, you need your own fence. Otherwise your fence is as good as your least interested neighbor.
It depends. I had fences on several sides of my yard growing up. Nobody doubled up. For the most part, it worked. It seems liked all of the fences had a primary owner who’s attitude was “I have a fence, it doesn’t matter if you have a fence, but I do - so I will pay to maintain my fence”
You have never dealt with government if you think asking anything even in good faith and especially in good faith is a good idea.
For some reason every bureaucracy is a host to a type of person that will go very far to make sure everything is in accordance with rules. If you draw attention to yourself they might want to check some ridiculous things that no sane person would ever actually pay attention to.
These are the ambitious bureaucrats and are probably the worst scum on earth. If you watched Andor you know who I am talking about. Not the lady but that security guy. This is the exact type.
Sure, most times you will not meet them but some totally amazing people.
But it’s enough to meet them once and your life could be ruined forever.
The power asymmetry is too strong to risk it.
I would rather act as if I was an outlaw and a guilty criminal with my dealings with government. Guilty, on all accounts. Now.. how to avoid the punishment?
That’s how we think about the government in Eastern Europe culturally. Whether that’s exotic or relatable to you as American, that will be interesting.
The government often claims exclusive authority and responsibility over the land but never acts on the responsibility they've asserted except to prevent anyone else from doing so. You can be required to pay a significant fee and file reams of paperwork to fix things for free that the government is expressly obligated to fix but never does.
It is common in parts of the US for government land to be illegally maintained by locals at their own expense because the government fails to do so. The impacted people aren't left with many other choices. There is little recourse when the government claims sole authority but also neglects its responsibilities under that authority.
This has been an issue in land management for as long as I've been alive. It sort of works to the extent the government is oddly incurious about someone else illegally doing their job for them. But every so often a bureaucrat with idle hands will decide to make an example of someone for illegal maintenance without addressing the underlying problem.
> Hey, I mean this in as kind a way as possible, but I actually don’t think the government should pay for the fence line!
Which is a fine option, but it should be something agreed to by both parties. You can't just hand over a cost like that, and if you buy property with some kind of agreement this choice is baked into the original price. It makes perfect sense for the government to uphold agreements it has made.
Secondly - if they did own the fence line, it'd be on the government to come and fix it when one of their trees breaks it, surely?
> It makes perfect sense for the government to uphold agreements it has made.
The key question is what is actually in the agreement. 'The state will maintain the fence' doesn't indicate the level of maintenance or the timeliness of said maintenance, it just means the neighbor isn't allowed to do it.
> Secondly - if they did own the fence line, it'd be on the government to come and fix it when one of their trees breaks it, surely?
From discussions I've seen, generally there's no legal responsibility for tree falls, unless there's neglegence like ignoring a clearly failing tree. But leaving a forest to do whatever the forest wants doesn't feel like neglegence.
Your position is that if the government builds a fence it is de facto obligated to maintain it to any abutting property owner's standards in perpetuity?
There is no agreement whatsoever, that's the point. No agreement was made or mentioned. The mere existence of a fence on government property does not constitute an agreement to maintain said fence.
I'm not stipulating anything about abutting property. I'm saying that if the government builds something on their land it is theirs to do with and is on them to maintain it. If they decide to no longer maintain it, that is also their decision. To clarify my point, if someone bought property when the government's fence was intact believing it will always remain so they did not have to build a fence, it is a bad decision on the neighbor's part and not the government's. If you require a fence, the only way to ensure you have a fence is to build and maintain your own fence. There are plenty of examples of the government building something on their land and then walking away and abandoning it when it is no longer needed.
>The mere existence of a fence on government property does not constitute an agreement to maintain said fence.
Can you imagine the sneering and hand wringing that would ensue in the comments if you tried to make such an argument about private property?
If a private landowner failed to maintain anything that was created by man (as opposed to nature) they'd say things like "public nuisance", "blighted", "antisocial" and all the other buzzword people of that bent love to use.
I don't really care what the standard is. If some standard is good enough to be worth legislating enforcing then it ought to apply equally to all land owners regardless of public or private.
It seems like everyone here is literally conjuring up first an agreement, and now laws out of thin air. What law is the state exempting itself?
Anyway tree law is super, super well-established and it works the same way for private parties. Your neighbor's trees are none of your business until they are on your property, and then they're exclusively your business (except you can't structurally damage or kill the tree e.g. by cutting roots that cross onto your property).
You clearly have some strange bone to pick. You should pick it elsewhere.
> Isn’t the premise of “you may as well own that land” the entire appeal of living next to public land anyway?
If you start actively managing it (removing invasive species, dead trees etc.) the state can take a more active interest at any time and sue/fine you into oblivion.
Right? Why have walls? Why have humans when we have wildlife? And dogs? Humans have only been sharing their company for more than twenty thousand years. Get over it, stop destroying the environment.
which is your next argumentative step? say your not disrupting an ecosystem that probably outlives the early human specie by hundreds of thousands of years? average North American that thinks just because you have money the planet and species living within are after your narcissistic ideals
And when they fall, they need to be dealt with. Responsible land management would assess whether the deadwood should be mulched and resoiled, left untouched, moved, etc. If a tree needs to be moved or broken down, you can't just bring heavy equipment or controlled burning to federal land.
It feels like the top commenter is simply sharing personal insight, not recriminating and pleading woe, so Idk why these responses act like they're being egregious. The situation simply requires cooperation with a government that apparently is loathe to go through the process with.
So move your fence 50 feet away from the property line. Obviously, this means you need to find a big property if it's adjacent to state land with large trees.
At that point he may be able to sue the state to fix it (or have insurance do it).
And if it’s your fence you can build one of the ones that’s cheap and easy to replace. I wouldn’t be shocked if you could put chain link back up after some straightening. You could use the downed tree to fix the fence if it was split log (not so good at keeping dogs in though)
Just to mention something people might not have ever considered, but basic home owner's insurance does not cover fences as they are not part of the house. I'm sure someone would be more than happy to provide additional coverage for additional fees that would cover a fence, but it's something to keep in mind. I know multiple people that were oblivious to this until their fence was damaged from trees falling on them during a storm.
That's a good point. What about wetlands? My property has a terrible mosquito problem and I just found out there is a pond/swamp hidden in the brush. Since it's my property, I'll take steps to reduce the mosquito problem next year but if it was public land, that'd probably wouldn't be acceptable.
If you throw some mosquito dunks with BT into any given water body small enough it doesn't have a name, nobody is going to come after you. I think it's probably a pretty prosocial thing to do, unless I'm missing something
My internal dialog can imagine my biologist wife yelling at you already.
Honestly i do not know the full scope of this one, but if there's one thing I've learnt from observing her work over the last decade...it's humans need to stop adding chemicals to water bodies with the goal of thinking they're helping something.
Note it's not a chemical agent; its bacterial spores that infect and kill mosquito larvae! I'm pretty sure they're not harmful to anything that isn't a mosquito, blackfly, gnat, or midge. Though midges are important to pond ecosystems as a source of food for fish and dragonflies and stuff? Idunno, ask this guy's wife.
I can imagine her having some long explanation about the unknown risks of man spreading this substance, even if its not a chemical agent. I lean on the edge of listening to Grandpa Simpson on these kind of things: https://i.imgur.com/MdjduDH.png
That ship has sailed. We’ve been spraying Bacillus thuringiensis as a pesticide for a century now, at a massive scale, and that scale probably pales in comparison to how prevalent the organism is worldwide naturally.
It might well be safe, but the question is what are the downstream affects of reducing the population of mosquitos (or other bugs in the water that this substance impacts). Maybe they've exclusively positive, but I assure you determining that is no walk in the park.
I always find it kind of odd that whenever any thing about reducing mosquitoes come out, you have a ton of people all echoing some variation of: "but what about all the possible effects"?
I don't know, what are the possible effects of antibiotics? What are the possible effects of uprooting weeds, which some organisms may depend on? What are the possible harmful effects of putting out wildfires?
For every action that someone might think of as beneficial, there are all sorts of "harmful" effects that can be posited. In the examples above, these harms are not even just theoretical, and yet people do not constantly wring their hands worrying about wildfire fighting, weed control, or the proper use of antibiotics.
That this seems to happen only with mosquitoes seems quite weird to me, especially when it occurs even with efforts to reduce mosquitoes that spread malaria and other diseases. People are oddly very worried about some nebulous harm caused by reducing real and serious harm now.
Hmm, actually specifically for the things you mentioned people did wring their hands and made changes to the procedure.
Wildfire - controlled wildfires are actually beneficial to prevent the real bad ones and help refertilize. So they now let them burn down if possible and just control the edges where necessary.
Weed control - poisoned groundwater from herbicides/pesticides is a huge headache, so these are tightly regulated on substances and amounts.
Antibiotics - multiresistant bacteria have taken over since years. In turn, antibiotics are now prescribed more rarely and for longer periods (to make it resistant survivors less likely) and new antibiotics had to be developed.
But that is my point: I specifically chose examples where people have an actual point to be concerned, and yet the amount of hand wringing over these issues pale in comparison to the concerns about mosquitoes.
But how do you know the hand wringing is less justified in this case? I imagine quite some time went by until the wringing was considered justified on all three accounts we previously talked about.
It depends. In North America our worst mosquitos (the disease carrying ones) aren't native, they are from the old world. I think everybody would be fine if they were no more.
> I think it's probably a pretty prosocial thing to do, unless I'm missing something
Agreed. I'm in South Texas where we have Aedes mosquitoes that are an invasive species and spread Malaria, Dengue, Zika, and other infections which kill people. I consider disrupting their lifecycle to be an unvarnished good. I carry mosquito dunks in my pocket when I go on walks and toss them into any puddles, drains, storm sewers, and ponds I encounter, and it seems to have helped a lot anecdotally. I care a lot about nature/ecology, but also fuck mosquitoes.
>I think it's probably a pretty prosocial thing to do, unless I'm missing something
Also massively illegal if you live anywhere that has a state level wetlands protection type law and the enforcement authority decides to exercise their discretion to make your life hell. They typically claim jurisdiction and authority over all activity in/around wetlands so theoretically you should be getting a state permit before digging a mailbox post hole or doing any sort of "management" of plants/animals but most of the time they just turn a blind eye to private homeowners who are being reasonable.
Wetlands laws and rules (non-criminal code generally, but wetlands are some of the worst) are written in a way to make RICO look like a meticulously scoped out piece of technical legislation.
First off, that's like asking your building inspectors "what can I do without a permit". Governments are dearth to "help out" like that. Even if you know a guy, the boundaries typically aren't binding until a survey has been done the state or municipality has a approved it and it's been registered with whoever handles land stuff in your jurisdiction.
Second, most states that regulate wetlands beyond the federal minimum adopt some sort of absurd expansive standard far above what the feds want. It's complex and varies by state. Sometimes there's a square footage minimum, sometimes there isn't. There's also "gotchas" where manmade areas can become wetlands if they are let to be that way too long, so like farmer Johnson can absolutely get screwed by his grandfather's bright idea to make all the drainage converge in one spot 40yr ago. Sometimes there are exemptions, sometimes not. There's huge variation by state and some states allow local governments to enforce rules above and beyond the state ones.
To be fair, my building inspector gave me a sheet entitled "what you can do without consulting the planning department" with like 8 pages and example deck/shed plans in it already.
It sounds like your expectations on your neighbour are way too high. Especially since them doing "their" part on par with your expectations benefits mostly just you.
When your neighbour isn't as invested as you in maintaining the border or has other annoyances you are better off leaving some buffer zone that allows to isolate yourself from the border and whatever road, river, canal, forest or loud or busy place is at the other side.
>>The biggest issue with sharing a border with the state is the fence line
Is it the physical blockade that the fence provides or just "where is the boundary?" - my guess is that it's both. While physical fence is hard to sustain due to trees falling but could there be an electronic solution for keeping the boundary line intact by putting some sort of gadgets underground which you can always ping to see where is the boundary?
In what state? Last I knew, the State Parks in most US states were miserably underfunded - so quick fixes (for pretty much anything, not just fences) just ain't gonna happen.
And what's the legal status of the fallen trees? In a fair number of places a 200' tree, already down, might be kinda valuable.
Mostly it doesn't pay to process individual lumber. If it's near a property it may have metal in it, and it's likely wood you can already find at a nearby lumber yard. If it's a particularly beautiful large tree, you have a use for slabs, can rent a skidsteer/forklift, and don't mind waiting a few years for it to season, it can be worth it. Or if you have a hankering for very large boards of unusual wood.
Apologies if this is somewhere else, but "price per acre" as a sorting mechanism would be really helpful. In the Dallas area, there's a few like $350k/0.2 acres (eg: a typical house on a lot).
Price per acre could suss out whether it's developed or in demand vs more rural (less price per acre).
Other than that, bravo! Great idea, well implemented!
I owned a house on 60 acres in Washington State that was bordered on 2 sides by state land (WA DNR). It was generally great and the only time I closed my gate was actually these two weeks of every year for regular rifle deer season. I never had issues with hunters coming on my property (I did give some friends permission to bow hunt). My driveway was about a mile long and had to cross DNR land to reach my property, but I had an easement. The easements typically have a 35 year expiration and it would take extreme circumstances for the state not to renew an existing easement. Complete and total privacy is really nice, but it's certainly a lot of effort and money to maintain a remote property of that size with a large house. I had to travel to SF a lot for work and that was certainly not ideal: 2.5 hour drive minimum to a tiny airport that only served Seattle, then on to SF.
At 60 acres you can probably do a 3000 feet grass strip runway. Get a Cessna and fly yourself, being within flying distance of a tiny airport in this case is pretty awesome. 2.5 hour drive is ~ 1 hour flight time for your C172s.
It really depends on how flat the terrain is and what the weather conditions are like. If it's often rainy, windy, or snowy, you might not have many opportunities to use the plane.
At some point, I think electric VTOL aircraft will make economic sense. Companies like Vight Aero are working on two seaters with decent range and speed.[1] Then you'd just need an area the size of a tennis court to take off and land. You also wouldn't have to ship fuel in, as you could charge the aircraft with off-grid solar. If that happens, I could see a lot of people moving away from cities.
Washington is already extremely expensive and our area was even more so. Water was free (well) but electric was very expensive and often went out. I put in a 48kw generac with a thousand gallon propane tank for backup which was a big project but very nice to have. Food, plowing, driveway maintenance, property stuff were all also high. (wife wouldn't let me get a beater 80's f-250 plow truck) Getting trades to even return a call was hard and could be months out for any jobs so I learned to do a lot on my own. I lived in WA for 25 years so just got used to the costs but moving to Boise last year made me realize it was insane.
This is interesting though not really for me. I know that without trails, I won't be walking past the end of my property onto other property. I've probably spent a year of my life building trails on my own property.
When I look for a parcel of land, I'm also interested in proximity to healthcare, groceries, airports (bad!), motor sports, shooting ranges; general steepness of the property particularly at the roadway (too steep makes the property unusable), topography in general (any flat spots to build a house?); availability of power; water features; bikability (checked by looking at Strava's heatmap); average number of days temperature > 85F; average number of days temperature < 30F. There's more but this list is long enough already.
This is super unreliable. I clicked through a few of the listings and none of them were what this site seemed to think they were. In one case it said a unit had 50 acres of land, and when I clicked through it was a two-bedroom condo with no land. Another said it had 1400 acres of land and when I clicked through it was 0.14.
The issue is how the MLS (multiple listing service) allows listing of condos/apartments/etc. Since each unit has no actual land to itself, they're allowed to list the total land that the complex sits on for each unit. There's also basically no oversight or correction on what gets listed, so listing agents have no reason to be accurate or perspicacious.
Everyone then scrapes or subscribes to the MLS data. It's why you have a dozen identical realty sites: Zillow, Realtor, Redfin, Trulia, etc.
Thanks, that's really nice to hear. Happy to share:
- Listings: RentCast's API (licensed), pulled weekly.
- Parcel boundaries: state and county GIS services where they publish statewide parcels (about 20 states), and Realie (licensed) for the rest.
- Public land: USGS PAD-US 4.1, filtered to fee-owned, open-access land of 50+ acres.
- Elevation: USGS 3DEP point queries. Roads: Census TIGER. Flood: FEMA's National Flood Hazard Layer. Wildfire: Forest Service Wildfire Hazard Potential (2023). ZIP search: Census ZCTA centroids.
The free state parcel services were the biggest hunt: every state publishes differently, and a couple that looked open turned out to be test or internal-use-only endpoints.
Not yet. The public-land source (USGS PAD-US) does include county/city land, but most of it is small parks, and I set a 50-acre minimum. County forests and large preserves are a good idea though, I'll look at adding those.
If you have public land do you just have people walking over the property boundary onto your parcel all the time? Especially in the more populous states like NJ some of them I'd expect that to be pretty common, interesting idea as a thing that people search out specifically for though.
Regardless, neat site. Couple things, first maybe a disclaimer on why you would want this on the home page? And on the state page itself I can't tell how bordering is different than adjacent. IMO just calling it "within 75m" would be better, and since this is for the US consider making it based on feet :p. Also, I would recommend that at least for user facing strings though you give it a little TLC and remove the really really obvious Claudisms
> official boundary maps, not listing descriptions.
> An analysis of publicly available boundary data — not a survey, and not a listing service
plus everything on the How It Works page is extremely obviously LLM.
My land is adjacent to public land and yes we have people coming through all the time. There is a forest road that becomes a private road and cuts through our land and people use it. We could put up a fence if we wanted but we don't want to... we're high enough up the hill that as long as people are being cool it's nbd. There are signs and most people (not all) are respectful.
I've found that living next to public land is an insanely undervalued luxury. There's very little I would trade it for.
On people crossing over: it depends a great deal on the land. Next to state game lands you'll see hunters in season; next to a big national forest you may rarely see anyone. It's very dependent on individual perspective and location.
Bordering vs adjacent: bordering means the parcel lines actually touch and there's a measured shared edge; adjacent means no shared edge but within about 250 ft (usually a road or a strip of other land in between). You're right that the state pages don't make that clear, and feet is the better unit for a US site. Tho most US geospatial data is published in metric lol.
And fair point on the copy. I run a small design studio and built this in my free time, I leaned on AI for a lot of the site text. The "Why this exists" section on How it works is my own story, but the rest deserves a pass in my own voice.
It's weird how people think navigating through undeveloped land is like walking across a parking lot. Brush, branches, thorns, downed trees, uneven ground, etc can make walking through undeveloped land difficult to impossible.
Really depends on the land in question. Some forests have thick underbrush, some are almost completely clear. A lot of undeveloped land isn't even forest - swamp, desert, rocky mountains. Sometimes it's far easier to navigate than a parking lot, IME.
Very true. Bordering a big block of public land doesn't mean you can walk through it easily, and the acreage number says nothing about brush or deadfall. That's part of why the site only reports what it can measure (the shared edge, the size, whether a mapped road reaches the parcel) and doesn't promise anything about getting around once you're out there. Trail data would be a nice addition someday.
I had a browse around a few states like Indiana and North Carolina, and was able to find plenty of low cost lots, even large ones, but the general problem is that they are miles away from civilization and on tiny local roads that may become an issue in winter.
It'd be useful to filter by proximity to a larger city, or airport.
Very cool idea though - some amazing large lots with beautiful views if you don't mind being pretty isolated.
This is cool, but isn't owning property bordering public land undesirable?
Sure, there's the ability to hike directly from your home, but I imagine you'll regularly have people wander on to your property. And if something illegal happens on your property by a different party, you might be liable.
Seems like the cons outweigh the pros. Or is there something I'm missing?
I think for an individual owner there are some downsides, but if you're a big developer buying a large piece of land it can become a selling point. There's a private residential development in my state where they completely enveloped the entrance to an existing state park trail/boardwalk. So to access it, you actually have to go through this gated community. Supposedly anyone can go in if they say they're going to the state park, but I'm not sure that's true in practice and you have to interact with the private guard gate and show ID. I was able to go in with my family, but we look like a typical suburban family, so that doesn't mean others wouldn't have more trouble. It's a pretty gross case of effectively privatizing a public resource.
That's the flip side of this: private land controlling the way into public land. It's a real problem in a lot of places, and an interesting thing to map someday.
American Prairie in Montana is an example going the other way: a nonprofit buying private land that surround public land and opening them to the public. It's somewhat contentious locally, but it shows how much the private parcels around public land shape who can actually use it.
It means a group of people unlikely to be stopped and turned away at that gate. My assumption is white, middle class, dressed boring but clean, decent car without damage, with young kid(s), no/light tattoos, no motorcyckes in the back and no drug/booze/gun stickers or visible stuff. Basically someone the Karen's won't call to complain about.
Other people deserve access to public land too but might not pass the vibe check of the private guards, which is what op was lamenting as well.
That would be a typical f150 family. A typical suburban family travels in a convoy of chevy suburbans. A luxury suburban family travels in a convoy of escalades.
> but I imagine you'll regularly have people wander on to your property
Well, that depends on how large and obvious your property is.
Assuming you have a typical suburban 1/2 acre or 1 acre property, the simplest thing to do is put up a fence, or otherwise make sure that there are no trails that go over the property you use.
Otherwise, you need some kind of bounds marking and obvious "no trespassing" signs.
FWIW: The site identified public lands near my house that have a lot of trails on it. There are trails that go right behind peoples' yards, and most of them either have fences or sheds that make it obvious where the bounds are.
That is going to depend on location. Most public land is way way out. There are often only a handful of visitors per month, and most of them won't get close to your land. Most of them are locals who know where the bounds are (and probably know you)
That matches my experience next to state game lands in PA. There's a few hunters in season who know where the lines, especially with OnX, Mostly quiet the rest of the year.
It means that nobody can build more houses "up the road" from you. That's the primary benefit. Unless the government sells the land, which this government has been trying to do in various places. This one issue is responsible for much of the reduction in republican support in Montana, for example
If you want similar benefits in more urban environments, consider property next to a cemetery. The neighbors are quiet and the lot is very unlikely to be turned into a strip mall.
It seems to not find quite a few properties that border public land. For example, if I scroll around Zillow to find stuff that borders the Gifford Pinchot national forest, I can find properties like this one.[1] But I don't see anything matching it on the Unfenced map.
I bought 20 acres bordering the national forest a couple years ago. The seller made sure I had some idea of what I was getting into. Due to the isolation and terrain, everything is more difficult. It's been a lot of work to build a road, level an area to build on, construct a shed, and set up off-grid solar power. But it's also very rewarding. The views are spectacular, and at night you can see the milky way. There's still a lot more work to do before it's worthy of being called a vacation spot, but I'm very happy with my decision.
This is super cool. I love this use of public data to do something cool. The page seems like it's biggest value is to help potential property buyers find property they wouldn't easily be able to otherwise (that's what I like about it). Given that, seems like being able to filter on cost and size of lot would be useful filters on top.
One big issue: not having a price and acreage range selectors means you see a lot of 0.2acre lots and $8mm parcels which I'm assuming most of us wouldn't be looking for
Yes! As another Pennsylvanian, this is a hard requirement for my forever home. The idea that I’d go all-in on a large property in an undeveloped area, only for the surrounding land to get developed or demolished is scary. State game lands is a way to protect against that outcome.
Also a concern is proximity to fracking and now data centers. Not sure how to see if neighbors sold their underground…
As an anecdote, my parent’s home, where I grew up, is a small plot along my town’s watershed property. When the price of lumber went up recently, the town council conveniently remembered that the watershed property was once a massive “tree farm,” and since has leveled all of the surrounding woods. We never expected this. It has been emotionally crushing.
Gonna have the same "issue" with private lands. Over the 20+ years I owned a tree farm in rural Oregon, numerous of the nearby parcels were clearcut. This has benefits too. One day I was up on my ridge and was surprised to see a mountain I had never seen before because the ridge to the north was just clearcut.
Very cool project. One of my favorite Show HN posts. It’s interesting to see how hard it is to line up the maps from different sources, but in most cases it is close enough to dig further. A really useful tool. Thank you
Thank you, that's great to hear. Honestly, the number of properties next to BLM was one of the things that surprised me most when I started building this, there's ~2,700 right now. On the map you can set the land type to BLM to see just those. And since you're always looking: any search can send you a weekly email when new matches turn up (starts Monday). Curious what else you check for on BLM-adjacent land?
No, they're in. About 470 properties border or sit near NPS land (parks, monuments, recreation areas, lakeshores), e.g. a few along the edge of the Smokies. You're right that the headline copy only mentions national forest, BLM and state land, so that's misleading; I need to update the wording. The map's land-type filter has a "National Park Service" option if you want to see just those.
Not that one. Parcels come from about 20 states' own statewide GIS services, and from Realie (licensed) for the rest. I'd want to check the license on that Kaggle dataset before using it, since county parcel data comes with all sorts of terms.
I know some folks to have a cabin that they use seasonally that borders national forest land. First of all, it's gorgeous and being able to open their back gate and walk out into unspoiled wilderness is awesome. But it does have some drawbacks; their biggest "neighbors" are cattle ranchers who let their cows graze in the forest. The cows will often wander onto their property, and the cowboys are not shy about breaking fences or cutting wire to get their cattle back out. Since they're only there for part of the year, they've also had issues with hunters breaking the locks and using their cabin as a place to hang out while they're not there.
Surprisingly easy to manage, though. You'd think that things like propane delivery and septic system service would be hard to hire when you're miles out of town, up a steep logging trail, and across a home-made bridge, but the local businesses are used to it. I genuinely don't know how they find the place most of the time.
Hi HN, I built this. Listings that say "borders state land" can't easily be checked: you open the county's GIS viewer and line up parcel lines against public-land maps by hand. I did that a lot while looking for land of my own, then automated it.
How it works, once a week:
1. About 700,000 active U.S. listings come in from a licensed listings API.
2. Each listing near public land gets its county parcel boundary, from state and county GIS services where they publish them and from a licensed parcel provider elsewhere. With no boundary, the page says so and measures from the listing point, but never claims a shared edge.
3. Public land is USGS PAD-US 4.1, narrowed to land an agency actually owns (Category = Fee, so no conservation easements), that's open to the public, and that's at least 50 acres.
4. Parcel and public land are compared in a local metric projection (shapely/geopandas): within (an inholding), bordering (the boundaries touch, and the shared edge is measured in feet), or adjacent (within 75 m, about a road's width).
Each property also gets the size of the connected public land behind it, its elevation (USGS 3DEP), road access (Census TIGER roads), FEMA flood zone and Forest Service wildfire hazard. The output is about 16,000 static pages with Leaflet maps on Cloudflare Pages, rebuilt every Monday on a Mac mini. ZIP search looks the ZIP up in your browser from Census centroids, so nothing you type is sent anywhere.
Things that were harder than expected:
- Lot sizes sometimes arrive in square feet in the acres field. A Birmingham, AL listing came through at 7,000 acres. Sizes are now checked against price, property type and the parcel itself, and corrected or withheld with a note.
- Condo and subdivision listings often resolve to the association's common tract, so a single town lot can appear to share miles of boundary. Those are flagged as shared parcels.
- PAD-US stores some units as one multipart polygon. My first "connected public land" figure for one Montana property was 69.7 million acres, about three-quarters of the state. Units are now split into pieces and joined only where they actually touch.
- Road centerlines and lot lines come from different agencies and are often tens of meters apart, so "does a road touch this parcel" needs a tolerance, and frontage only counts where the boundary runs along the road.
It's free, with no account and no cookies. There are free weekly email alerts for any search, starting Monday. I'd especially like to hear from anyone who has bought rural land: what should it measure that it doesn't?

It's RentCast (rentcast.io) listings API and parcel boundaries come from state/county GIS services and Realie (realie.ai).

Mostly Claude Code. I have a background in 3D Design and Geospatial Mapping, the data sources and the decisions about what counts as "bordering" were mine
I'd love to chat to you about this. I have been solo building in the real estate space for about 5 years now. I've finally got to a point where I make a roughly market salary from it, and I'm starting to venture wider into providing a listing service for everyone from FSBO's to large brokerages. Theres a huge opportunity to displace the position Zillow et al have, but it's riddled with legal challenges and risk (They've done a great job of making it hard to break in).
If you're up for a chat, please ping me! This is pretty cool and I'm wondering if theres a collaboration, or if I can straight up use some of what you've made.
First, this is cool! Well done.
I live next to a State Park. It sounded really cool when I bought the house. No neighbors! Privacy! There is a trail accessible from my properly that goes into some woods, which you only want to be in during the Fall / Spring because the ticks and chiggers are intense.
The biggest issue with sharing a border with the state is the fence line. Technically it's on them to maintain. The woods are filled with mostly 200 foot trees. They exist right up to my property and fall every year during big storms. There goes the fence line. I have dogs so the fence is important. Otherwise they run out into the woods that have licensed bow-hunting during the Winter.
In practice its impossible to get the fence fixed. You are working through layers of bureaucracy and mismanagement. There is no vested interest from a parks service to work well with hundreds of neighbors individually. I'd build fence lines myself, and could easily pay for it, but it's the upkeep of those fences that would be difficult because so many trees (really, it's every year) fall down from their side.
My main point is that sharing a properly line with the government is more like sharing a properly line with nobody. You may as well own that land. Don't expect any upkeep and go in with eyes open.
Hey, I mean this in as kind a way as possible, but I actually don’t think the government should pay for the fence line!
If you wouldn’t even pay for it yourself, as pretty much the sole beneficiary and someone who could afford it but would rather the money go elsewhere, why would it make sense for other taxpayers to pay for it?
Isn’t the premise of “you may as well own that land” the entire appeal of living next to public land anyway?
My family used to live next to state land. The state can be very pissy about its land. If the fence line is on the state land, which it almost certainly is barring a surveying error when it was put up, it is entirely possible that if he fixed it, he would actually get in trouble with the state. Hopefully not actual legal trouble... but only hopefully, certainly not a "oh they would never bother". Oh they most certainly do sometimes decide to bother about the most random things.
My default presumption, without checking with them directly, is not only that it would not be allowed, but that this is also very much not a "better to ask forgiveness than permission" situation either. Even just asking the question can draw attention from them you may not want.
The ready accessibility of the land is advantageous in some ways, but as neighbors the state can be quite nasty. Your other neighbors don't tend to have anywhere near the regulatory firepower to make sure you comply with what they want.
I think they’re suggesting building their own fence on their own property and eating the cost (as the sole beneficiary) of maintaining it through tree falls.
When a 200 ft tree at the fence line falls into your property that can take away much of your usable land.
Cleaning up fallen trees is part of owning a property in these areas. Doesn’t matter where the fence is.
But isn't that typically the responsibility of the person who owns the land that the tree was sitting on before it fell?
Nope (though it does depend). I’ve been through several trees falling from storms.
Unless negligence is involve (like an arborist being hired to condemn a tree), they’re generally considered and act of god. They’re the responsibility of the property they fall onto.
So, in the case of OP, the situation is unfortunate, but it’s on him to maintain his properties and his fence lines within his properties. It’s convenient the state has a fence along part of his property, but it’s not their responsibility to fix it for adjacent lots.
It Depends(tm).
Practically you’re right of course, but they are probably technically responsible given the circumstances the poster laid out.
A landowner is definitely not "technically responsible" for cleaning up trees that fall along or across the border of their property.
If they are aware of a dangerous situation (diseased trees), and don’t do something about it, they are definitely on the hook for property damage caused by that negligence.
It would boil down to their degree of plausible deniability, ‘state priviledge’, and the specifics of the law and precedent in their state of course.
Good luck
The situation described says nothing about diseased trees. It says "I live next to a forest and trees fall."
I recently learned at least here in Germany it's not. Because larger trees are protected, you're generally not allowed to remove them even if they are close to another property. When they fall, it's considered force of nature and you won't be blamed. Unless, of course, the tree wasn't healthy in the first place and would be considered a danger.
How that works out in practice is basically you as the owner of the tree have to document it's healthy each year. Then, if it falls and you can prove it was healthy you're fine. Hopefully neighbors insurance pays. If you didn't document the health of the tree, your neighbor can press charges and you (or your insurance) have to pay.
Tree law.
Oh my god you're right.
I think I unintentionally brought Tree Law to HN.
Now that I think of this may be the first time that I've seen Tree Law on here.
We're only a hop, skip and a jump from getting some vigorous discussion about Bay area Tree Law now.
nope. live in the forest, take care of yourself. a 250' sitka spruce fell from my neighbor's property onto the roof of my detached garage. it cost over 10k to fix it. the neighbor was not liable; it was covered by insurance
There is the legal responsibility, and the practical ability to get things done/protect/help oneself.
What they are noting is the State is it’s own beast, and good luck getting it to do what you want.
This also is not a city type situation, where the density and value of something makes certain types of situations play out differently.
In the city, if a neighbor’s diseased tree falls on your house, you might have a legitimate legal claim, depending on the circumstances.
Your homeowners insurance will figure that out.
If one of the million random trees on state property falls on your fence? It doesn’t much matter what the law says, good luck.
And provide firewood to heat your home for the year. Depending on how much of a problem the broken fence is, you might even like it to fall your way.
Depending on the size of the tree and your home you might have enough to sell to the neighbors too.
I'm assuming the state doesn't come around asking for payment for their fallen trees.
Fences are expensive. Firewood really isn't unless you're silly enough to spend money on the guys who come out and stack it for you for $600 a full cord. Awhile back I was getting 13 loggers cords for $1000, delivered, with the only caveat I had to cut and split and stack it myself. Upshot: I got to cancel my gym membership for the summer because that's a lot of work.
Fences can be made out of the tree that fell. Even post holes are optional. Only thing you need to pay for is some cheap wire mesh, and that may be reusable for repairs.
> If the fence line is on the state land, which it almost certainly is barring a surveying error when it was put up, it is entirely possible that if he fixed it, he would actually get in trouble with the state
Trying to maintain the state’s fence is not a good idea.
You would build your own fence on your side of the property set back by a couple feet.
> If the fence line is on the state land, which it almost certainly is barring a surveying error when it was put up, it is entirely possible that if he fixed it, he would actually get in trouble with the state.
Oh, the joys of living in a place with actual rule of law.
Here in my 3rd world country, people are free to annex land demarcated for streets that adjoin their property, without any real consequences, as long as it is not meant to be a major street.
I'd also assume the fence is on state land if its theirs to maintain. That doesn't stop someone from putting up their own fence on their side of the property line though.
You couldn't integrate it into theirs, so you'd be looking at having to fence in the entire space you want the dogs in because the gap you'd leave would have to be big enough for a dog.
Which is hardly the end of the world, but it can definitely grind the gears to be spending thousands when you could fix the problem for several hundreds, if not perhaps several tens, of dollars if they wouldn't be assholes about it. But I would absolutely advise anyone in that situation to spend the thousands and not bank on the state not being assholes about it.
I can also add that you can't even be sure that if you got away with it for years that you will continue to get away with it. The particular issue that my father got into a bit of hassle with the state about is that he accidentally put a pole barn across the state line. Didn't mean to, but he misread the survey markers. Fortunately, they let him remediate it at his expense without pursuing the matter any further legally... but it means they did, after several years of it being there, come through a with a survey team and verify that nobody on the border was crossing into their land, and anything they found they made the residents fix no matter how many years the deviation had been there. All the laws about such thing between two citizens mean nothing to the state.
> You couldn't integrate it into theirs, so you'd be looking at having to fence in the entire space you want the dogs in because the gap you'd leave would have to be big enough for a dog.
These properties only border public land on one side.
If someone is trying to fence their dogs into their property, it’s implied that they’re already fencing every other part of the property. They would be completing it with a back section.
> You couldn't integrate it into theirs, so you'd be looking at having to fence in the entire space
Oh no. Tbe preposterous idea of putting a fence around your own property.
If you're planning on posting snark it's generally a good idea to make sure you read the rest of the post first.
I read the rest if the post and it makes no sense. The father story is non-sequitur, and this can only be interpreted as the poster not knowing how fences work: "you'd be looking at having to fence in the entire space you want the dogs in because the gap you'd leave would have to be big enough for a dog."
A sibling comment pointed this out, too: https://news.ycombinator.com/item?id=50105376
Will the state pay when their trees fall onto a private property and break the fence?
In the US, if a neighbor's tree falls on your house, they are likely only liable if it was due to negligence. I don't see how the state could possibly be liable for a tree on public land falling on someone's fence. Why would tax payers want to foot that bill?
Pretty much my exact thoughts as well. Heaven forbid a property owning pet owner be responsible for protecting their pets on their property. WTF has this world come to?
It's very common to build a fence on your own land, even if your neighbors have a fence?
Like my neighbors have a fence, I have a fence, there is like a 1' alley in between them, everything is on the respective owner's land, and that would definitely work even if your neighbor is the government.
If fence integrity is important, you need your own fence. Otherwise your fence is as good as your least interested neighbor.
It depends. I had fences on several sides of my yard growing up. Nobody doubled up. For the most part, it worked. It seems liked all of the fences had a primary owner who’s attitude was “I have a fence, it doesn’t matter if you have a fence, but I do - so I will pay to maintain my fence”
It worked.
You have never dealt with government if you think asking anything even in good faith and especially in good faith is a good idea.
For some reason every bureaucracy is a host to a type of person that will go very far to make sure everything is in accordance with rules. If you draw attention to yourself they might want to check some ridiculous things that no sane person would ever actually pay attention to.
These are the ambitious bureaucrats and are probably the worst scum on earth. If you watched Andor you know who I am talking about. Not the lady but that security guy. This is the exact type.
Sure, most times you will not meet them but some totally amazing people.
But it’s enough to meet them once and your life could be ruined forever.
The power asymmetry is too strong to risk it.
I would rather act as if I was an outlaw and a guilty criminal with my dealings with government. Guilty, on all accounts. Now.. how to avoid the punishment?
That’s how we think about the government in Eastern Europe culturally. Whether that’s exotic or relatable to you as American, that will be interesting.
The government often claims exclusive authority and responsibility over the land but never acts on the responsibility they've asserted except to prevent anyone else from doing so. You can be required to pay a significant fee and file reams of paperwork to fix things for free that the government is expressly obligated to fix but never does.
It is common in parts of the US for government land to be illegally maintained by locals at their own expense because the government fails to do so. The impacted people aren't left with many other choices. There is little recourse when the government claims sole authority but also neglects its responsibilities under that authority.
This has been an issue in land management for as long as I've been alive. It sort of works to the extent the government is oddly incurious about someone else illegally doing their job for them. But every so often a bureaucrat with idle hands will decide to make an example of someone for illegal maintenance without addressing the underlying problem.
> Hey, I mean this in as kind a way as possible, but I actually don’t think the government should pay for the fence line!
Which is a fine option, but it should be something agreed to by both parties. You can't just hand over a cost like that, and if you buy property with some kind of agreement this choice is baked into the original price. It makes perfect sense for the government to uphold agreements it has made.
Secondly - if they did own the fence line, it'd be on the government to come and fix it when one of their trees breaks it, surely?
> It makes perfect sense for the government to uphold agreements it has made.
The key question is what is actually in the agreement. 'The state will maintain the fence' doesn't indicate the level of maintenance or the timeliness of said maintenance, it just means the neighbor isn't allowed to do it.
> Secondly - if they did own the fence line, it'd be on the government to come and fix it when one of their trees breaks it, surely?
From discussions I've seen, generally there's no legal responsibility for tree falls, unless there's neglegence like ignoring a clearly failing tree. But leaving a forest to do whatever the forest wants doesn't feel like neglegence.
Did the government agree to maintain a fence…?
If the government built a fence on their property, the burden is on them to maintain it. What other agreement is there?
Your position is that if the government builds a fence it is de facto obligated to maintain it to any abutting property owner's standards in perpetuity?
There is no agreement whatsoever, that's the point. No agreement was made or mentioned. The mere existence of a fence on government property does not constitute an agreement to maintain said fence.
I'm not stipulating anything about abutting property. I'm saying that if the government builds something on their land it is theirs to do with and is on them to maintain it. If they decide to no longer maintain it, that is also their decision. To clarify my point, if someone bought property when the government's fence was intact believing it will always remain so they did not have to build a fence, it is a bad decision on the neighbor's part and not the government's. If you require a fence, the only way to ensure you have a fence is to build and maintain your own fence. There are plenty of examples of the government building something on their land and then walking away and abandoning it when it is no longer needed.
Okay so I don't know why you're responding as if you're disagreeing with me.
We're on the same page.
>The mere existence of a fence on government property does not constitute an agreement to maintain said fence.
Can you imagine the sneering and hand wringing that would ensue in the comments if you tried to make such an argument about private property?
If a private landowner failed to maintain anything that was created by man (as opposed to nature) they'd say things like "public nuisance", "blighted", "antisocial" and all the other buzzword people of that bent love to use.
I don't really care what the standard is. If some standard is good enough to be worth legislating enforcing then it ought to apply equally to all land owners regardless of public or private.
It seems like everyone here is literally conjuring up first an agreement, and now laws out of thin air. What law is the state exempting itself?
Anyway tree law is super, super well-established and it works the same way for private parties. Your neighbor's trees are none of your business until they are on your property, and then they're exclusively your business (except you can't structurally damage or kill the tree e.g. by cutting roots that cross onto your property).
You clearly have some strange bone to pick. You should pick it elsewhere.
There's plenty enough of unmaintained fences between rural properties in the middle of nowhere.
Are you going to call the HOA on the government to enforce them to maintain their fence?
> Isn’t the premise of “you may as well own that land” the entire appeal of living next to public land anyway?
If you start actively managing it (removing invasive species, dead trees etc.) the state can take a more active interest at any time and sue/fine you into oblivion.
Yup, and this becomes a very real issue if there is something like serious fire danger due to lack of (politically untenable) logging.
Or a serious pest issue (someone mentioned ticks, for instance).
Pros and cons of the situation, for sure.
I think the gist is more something like: you should expect the government to neglect their property.
Put up your own fence inside of your property line that you can keep up to your needs and standards.
Sounds like trees would fall onto it every year :/
That’s what happens when you have lots of trees on or adjacent to your property.
If that bothers you, don’t buy property adjacent to 200ft tall trees. They will fall. That’s what trees do. They grow, then die and fall over.
or better! exercise and support the freedom to roam [0] by not having fences and have no dogs which probably disrupt wildlife too
[0] https://en.wikipedia.org/wiki/Freedom_to_roam
Right? Why have walls? Why have humans when we have wildlife? And dogs? Humans have only been sharing their company for more than twenty thousand years. Get over it, stop destroying the environment.
which is your next argumentative step? say your not disrupting an ecosystem that probably outlives the early human specie by hundreds of thousands of years? average North American that thinks just because you have money the planet and species living within are after your narcissistic ideals
And when they fall, they need to be dealt with. Responsible land management would assess whether the deadwood should be mulched and resoiled, left untouched, moved, etc. If a tree needs to be moved or broken down, you can't just bring heavy equipment or controlled burning to federal land.
It feels like the top commenter is simply sharing personal insight, not recriminating and pleading woe, so Idk why these responses act like they're being egregious. The situation simply requires cooperation with a government that apparently is loathe to go through the process with.
At least they'd have control and can fix it as they see fit, instead of waiting for the government.
So move your fence 50 feet away from the property line. Obviously, this means you need to find a big property if it's adjacent to state land with large trees.
At that point he may be able to sue the state to fix it (or have insurance do it).
And if it’s your fence you can build one of the ones that’s cheap and easy to replace. I wouldn’t be shocked if you could put chain link back up after some straightening. You could use the downed tree to fix the fence if it was split log (not so good at keeping dogs in though)
Just to mention something people might not have ever considered, but basic home owner's insurance does not cover fences as they are not part of the house. I'm sure someone would be more than happy to provide additional coverage for additional fees that would cover a fence, but it's something to keep in mind. I know multiple people that were oblivious to this until their fence was damaged from trees falling on them during a storm.
Yes it’s because fences break constantly. So it would be less “insurance” and more like a forced savings plan.
I assume this kind of property is large enough that OP can afford to build the second fence one tree height away from the property line.
That's a good point. What about wetlands? My property has a terrible mosquito problem and I just found out there is a pond/swamp hidden in the brush. Since it's my property, I'll take steps to reduce the mosquito problem next year but if it was public land, that'd probably wouldn't be acceptable.
If you throw some mosquito dunks with BT into any given water body small enough it doesn't have a name, nobody is going to come after you. I think it's probably a pretty prosocial thing to do, unless I'm missing something
Doing that on public land is a risk. The USFS absolutely has restrictions on chemical usage. For example, pressure treated lumber is not allowed.
My internal dialog can imagine my biologist wife yelling at you already.
Honestly i do not know the full scope of this one, but if there's one thing I've learnt from observing her work over the last decade...it's humans need to stop adding chemicals to water bodies with the goal of thinking they're helping something.
Note it's not a chemical agent; its bacterial spores that infect and kill mosquito larvae! I'm pretty sure they're not harmful to anything that isn't a mosquito, blackfly, gnat, or midge. Though midges are important to pond ecosystems as a source of food for fish and dragonflies and stuff? Idunno, ask this guy's wife.
I will ask her and report back...
I can imagine her having some long explanation about the unknown risks of man spreading this substance, even if its not a chemical agent. I lean on the edge of listening to Grandpa Simpson on these kind of things: https://i.imgur.com/MdjduDH.png
That ship has sailed. We’ve been spraying Bacillus thuringiensis as a pesticide for a century now, at a massive scale, and that scale probably pales in comparison to how prevalent the organism is worldwide naturally.
I mean, there are unknown risks to having children, to eating, to having mosquitoes around, to pretty much everything.
It is not meaningful to allow every conceivable unknown unknown (to channel Rumsfeld) suck out any sense of agency.
Mosquito dunk is some kind of microbial culture that’s supposed to be safe.
The path to hell is paved with good intentions: https://en.wikipedia.org/wiki/Cane_toads_in_Australia
It might well be safe, but the question is what are the downstream affects of reducing the population of mosquitos (or other bugs in the water that this substance impacts). Maybe they've exclusively positive, but I assure you determining that is no walk in the park.
I always find it kind of odd that whenever any thing about reducing mosquitoes come out, you have a ton of people all echoing some variation of: "but what about all the possible effects"?
I don't know, what are the possible effects of antibiotics? What are the possible effects of uprooting weeds, which some organisms may depend on? What are the possible harmful effects of putting out wildfires?
For every action that someone might think of as beneficial, there are all sorts of "harmful" effects that can be posited. In the examples above, these harms are not even just theoretical, and yet people do not constantly wring their hands worrying about wildfire fighting, weed control, or the proper use of antibiotics.
That this seems to happen only with mosquitoes seems quite weird to me, especially when it occurs even with efforts to reduce mosquitoes that spread malaria and other diseases. People are oddly very worried about some nebulous harm caused by reducing real and serious harm now.
Hmm, actually specifically for the things you mentioned people did wring their hands and made changes to the procedure.
Wildfire - controlled wildfires are actually beneficial to prevent the real bad ones and help refertilize. So they now let them burn down if possible and just control the edges where necessary.
Weed control - poisoned groundwater from herbicides/pesticides is a huge headache, so these are tightly regulated on substances and amounts.
Antibiotics - multiresistant bacteria have taken over since years. In turn, antibiotics are now prescribed more rarely and for longer periods (to make it resistant survivors less likely) and new antibiotics had to be developed.
But that is my point: I specifically chose examples where people have an actual point to be concerned, and yet the amount of hand wringing over these issues pale in comparison to the concerns about mosquitoes.
But how do you know the hand wringing is less justified in this case? I imagine quite some time went by until the wringing was considered justified on all three accounts we previously talked about.
I can see the headline now:
"Mosquito dunks linked to declining bear population - farmers struggling with deer populations"
ha yeah, that's exactly where my brain goes too.
meh, they'll just reintroduce wolves. man is much too smart to be outdone by mother nature /s
The mosquitoes don't exist in isolation though. Isn't this exactly how food chains / ecosystems work? You can't remove a tier without consequences.
It depends. In North America our worst mosquitos (the disease carrying ones) aren't native, they are from the old world. I think everybody would be fine if they were no more.
> I think it's probably a pretty prosocial thing to do, unless I'm missing something
Agreed. I'm in South Texas where we have Aedes mosquitoes that are an invasive species and spread Malaria, Dengue, Zika, and other infections which kill people. I consider disrupting their lifecycle to be an unvarnished good. I carry mosquito dunks in my pocket when I go on walks and toss them into any puddles, drains, storm sewers, and ponds I encounter, and it seems to have helped a lot anecdotally. I care a lot about nature/ecology, but also fuck mosquitoes.
>I think it's probably a pretty prosocial thing to do, unless I'm missing something
Also massively illegal if you live anywhere that has a state level wetlands protection type law and the enforcement authority decides to exercise their discretion to make your life hell. They typically claim jurisdiction and authority over all activity in/around wetlands so theoretically you should be getting a state permit before digging a mailbox post hole or doing any sort of "management" of plants/animals but most of the time they just turn a blind eye to private homeowners who are being reasonable.
Wetlands laws and rules (non-criminal code generally, but wetlands are some of the worst) are written in a way to make RICO look like a meticulously scoped out piece of technical legislation.
I thought you could ask your local assessor or judge where the WOTUS line is? If so, you do your management up to just short of the line.
First off, that's like asking your building inspectors "what can I do without a permit". Governments are dearth to "help out" like that. Even if you know a guy, the boundaries typically aren't binding until a survey has been done the state or municipality has a approved it and it's been registered with whoever handles land stuff in your jurisdiction.
Second, most states that regulate wetlands beyond the federal minimum adopt some sort of absurd expansive standard far above what the feds want. It's complex and varies by state. Sometimes there's a square footage minimum, sometimes there isn't. There's also "gotchas" where manmade areas can become wetlands if they are let to be that way too long, so like farmer Johnson can absolutely get screwed by his grandfather's bright idea to make all the drainage converge in one spot 40yr ago. Sometimes there are exemptions, sometimes not. There's huge variation by state and some states allow local governments to enforce rules above and beyond the state ones.
To be fair, my building inspector gave me a sheet entitled "what you can do without consulting the planning department" with like 8 pages and example deck/shed plans in it already.
But yeah I don't mess with wetlands.
It sounds like your expectations on your neighbour are way too high. Especially since them doing "their" part on par with your expectations benefits mostly just you.
When your neighbour isn't as invested as you in maintaining the border or has other annoyances you are better off leaving some buffer zone that allows to isolate yourself from the border and whatever road, river, canal, forest or loud or busy place is at the other side.
>>The biggest issue with sharing a border with the state is the fence line
Is it the physical blockade that the fence provides or just "where is the boundary?" - my guess is that it's both. While physical fence is hard to sustain due to trees falling but could there be an electronic solution for keeping the boundary line intact by putting some sort of gadgets underground which you can always ping to see where is the boundary?
Do you have room to put up a fence away from the treeline?
I know this wasn't your point but you could get a buried wire fence for your dogs. Or outfit them in beautiful orange jackets in the winter
> I live next to a State Park.
In what state? Last I knew, the State Parks in most US states were miserably underfunded - so quick fixes (for pretty much anything, not just fences) just ain't gonna happen.
And what's the legal status of the fallen trees? In a fair number of places a 200' tree, already down, might be kinda valuable.
Mostly it doesn't pay to process individual lumber. If it's near a property it may have metal in it, and it's likely wood you can already find at a nearby lumber yard. If it's a particularly beautiful large tree, you have a use for slabs, can rent a skidsteer/forklift, and don't mind waiting a few years for it to season, it can be worth it. Or if you have a hankering for very large boards of unusual wood.
I'd much rather do yearly fence maintenance than deal with neighbors.
Apologies if this is somewhere else, but "price per acre" as a sorting mechanism would be really helpful. In the Dallas area, there's a few like $350k/0.2 acres (eg: a typical house on a lot).
Price per acre could suss out whether it's developed or in demand vs more rural (less price per acre).
Other than that, bravo! Great idea, well implemented!
I owned a house on 60 acres in Washington State that was bordered on 2 sides by state land (WA DNR). It was generally great and the only time I closed my gate was actually these two weeks of every year for regular rifle deer season. I never had issues with hunters coming on my property (I did give some friends permission to bow hunt). My driveway was about a mile long and had to cross DNR land to reach my property, but I had an easement. The easements typically have a 35 year expiration and it would take extreme circumstances for the state not to renew an existing easement. Complete and total privacy is really nice, but it's certainly a lot of effort and money to maintain a remote property of that size with a large house. I had to travel to SF a lot for work and that was certainly not ideal: 2.5 hour drive minimum to a tiny airport that only served Seattle, then on to SF.
At 60 acres you can probably do a 3000 feet grass strip runway. Get a Cessna and fly yourself, being within flying distance of a tiny airport in this case is pretty awesome. 2.5 hour drive is ~ 1 hour flight time for your C172s.
It really depends on how flat the terrain is and what the weather conditions are like. If it's often rainy, windy, or snowy, you might not have many opportunities to use the plane.
At some point, I think electric VTOL aircraft will make economic sense. Companies like Vight Aero are working on two seaters with decent range and speed.[1] Then you'd just need an area the size of a tennis court to take off and land. You also wouldn't have to ship fuel in, as you could charge the aircraft with off-grid solar. If that happens, I could see a lot of people moving away from cities.

What would realistically be a ballpark expense for basic living (I assume you mean food water and power)
Washington is already extremely expensive and our area was even more so. Water was free (well) but electric was very expensive and often went out. I put in a 48kw generac with a thousand gallon propane tank for backup which was a big project but very nice to have. Food, plowing, driveway maintenance, property stuff were all also high. (wife wouldn't let me get a beater 80's f-250 plow truck) Getting trades to even return a call was hard and could be months out for any jobs so I learned to do a lot on my own. I lived in WA for 25 years so just got used to the costs but moving to Boise last year made me realize it was insane.
This is interesting though not really for me. I know that without trails, I won't be walking past the end of my property onto other property. I've probably spent a year of my life building trails on my own property.
When I look for a parcel of land, I'm also interested in proximity to healthcare, groceries, airports (bad!), motor sports, shooting ranges; general steepness of the property particularly at the roadway (too steep makes the property unusable), topography in general (any flat spots to build a house?); availability of power; water features; bikability (checked by looking at Strava's heatmap); average number of days temperature > 85F; average number of days temperature < 30F. There's more but this list is long enough already.
This is super unreliable. I clicked through a few of the listings and none of them were what this site seemed to think they were. In one case it said a unit had 50 acres of land, and when I clicked through it was a two-bedroom condo with no land. Another said it had 1400 acres of land and when I clicked through it was 0.14.
The issue is how the MLS (multiple listing service) allows listing of condos/apartments/etc. Since each unit has no actual land to itself, they're allowed to list the total land that the complex sits on for each unit. There's also basically no oversight or correction on what gets listed, so listing agents have no reason to be accurate or perspicacious.
Everyone then scrapes or subscribes to the MLS data. It's why you have a dozen identical realty sites: Zillow, Realtor, Redfin, Trulia, etc.
It's blowing mind a bit that you made this and released it because I was on the verge of doing it myself. Very nice work.
Really curious about your data sources. Where are you getting all this stuff?
Thanks, that's really nice to hear. Happy to share:
- Listings: RentCast's API (licensed), pulled weekly.
- Parcel boundaries: state and county GIS services where they publish statewide parcels (about 20 states), and Realie (licensed) for the rest.
- Public land: USGS PAD-US 4.1, filtered to fee-owned, open-access land of 50+ acres.
- Elevation: USGS 3DEP point queries. Roads: Census TIGER. Flood: FEMA's National Flood Hazard Layer. Wildfire: Forest Service Wildfire Hazard Potential (2023). ZIP search: Census ZCTA centroids.
The free state parcel services were the biggest hunt: every state publishes differently, and a couple that looked open turned out to be test or internal-use-only endpoints.
Any possibility to include city or county-owned land too?
Not yet. The public-land source (USGS PAD-US) does include county/city land, but most of it is small parks, and I set a 50-acre minimum. County forests and large preserves are a good idea though, I'll look at adding those.
If you have public land do you just have people walking over the property boundary onto your parcel all the time? Especially in the more populous states like NJ some of them I'd expect that to be pretty common, interesting idea as a thing that people search out specifically for though.
Regardless, neat site. Couple things, first maybe a disclaimer on why you would want this on the home page? And on the state page itself I can't tell how bordering is different than adjacent. IMO just calling it "within 75m" would be better, and since this is for the US consider making it based on feet :p. Also, I would recommend that at least for user facing strings though you give it a little TLC and remove the really really obvious Claudisms
> official boundary maps, not listing descriptions.
> An analysis of publicly available boundary data — not a survey, and not a listing service
plus everything on the How It Works page is extremely obviously LLM.
My land is adjacent to public land and yes we have people coming through all the time. There is a forest road that becomes a private road and cuts through our land and people use it. We could put up a fence if we wanted but we don't want to... we're high enough up the hill that as long as people are being cool it's nbd. There are signs and most people (not all) are respectful.
I've found that living next to public land is an insanely undervalued luxury. There's very little I would trade it for.
Thanks, this is useful feedback.
On people crossing over: it depends a great deal on the land. Next to state game lands you'll see hunters in season; next to a big national forest you may rarely see anyone. It's very dependent on individual perspective and location.
Bordering vs adjacent: bordering means the parcel lines actually touch and there's a measured shared edge; adjacent means no shared edge but within about 250 ft (usually a road or a strip of other land in between). You're right that the state pages don't make that clear, and feet is the better unit for a US site. Tho most US geospatial data is published in metric lol.
And fair point on the copy. I run a small design studio and built this in my free time, I leaned on AI for a lot of the site text. The "Why this exists" section on How it works is my own story, but the rest deserves a pass in my own voice.
> I leaned on AI for a lot of the site text.
So that's why the site text reads as AI slop.
> checked against official boundary maps, not listing descriptions.
Were you ever seriously fooled?
For real. Just write it yourself.
I demand a refund!
It's weird how people think navigating through undeveloped land is like walking across a parking lot. Brush, branches, thorns, downed trees, uneven ground, etc can make walking through undeveloped land difficult to impossible.
Really depends on the land in question. Some forests have thick underbrush, some are almost completely clear. A lot of undeveloped land isn't even forest - swamp, desert, rocky mountains. Sometimes it's far easier to navigate than a parking lot, IME.
Very true. Bordering a big block of public land doesn't mean you can walk through it easily, and the acreage number says nothing about brush or deadfall. That's part of why the site only reports what it can measure (the shared edge, the size, whether a mapped road reaches the parcel) and doesn't promise anything about getting around once you're out there. Trail data would be a nice addition someday.
A price filter would be useful.
Most of the listings near me are for tens of acres and >$5 million
Agreed that some more filters would be useful.
I had a browse around a few states like Indiana and North Carolina, and was able to find plenty of low cost lots, even large ones, but the general problem is that they are miles away from civilization and on tiny local roads that may become an issue in winter.
It'd be useful to filter by proximity to a larger city, or airport.
Very cool idea though - some amazing large lots with beautiful views if you don't mind being pretty isolated.
This is cool, but isn't owning property bordering public land undesirable?
Sure, there's the ability to hike directly from your home, but I imagine you'll regularly have people wander on to your property. And if something illegal happens on your property by a different party, you might be liable.
Seems like the cons outweigh the pros. Or is there something I'm missing?
I think for an individual owner there are some downsides, but if you're a big developer buying a large piece of land it can become a selling point. There's a private residential development in my state where they completely enveloped the entrance to an existing state park trail/boardwalk. So to access it, you actually have to go through this gated community. Supposedly anyone can go in if they say they're going to the state park, but I'm not sure that's true in practice and you have to interact with the private guard gate and show ID. I was able to go in with my family, but we look like a typical suburban family, so that doesn't mean others wouldn't have more trouble. It's a pretty gross case of effectively privatizing a public resource.
That's the flip side of this: private land controlling the way into public land. It's a real problem in a lot of places, and an interesting thing to map someday.
American Prairie in Montana is an example going the other way: a nonprofit buying private land that surround public land and opening them to the public. It's somewhat contentious locally, but it shows how much the private parcels around public land shape who can actually use it.
> I was able to go in with my family, but we look like a typical suburban family.
How does the typical suburban family look like? Did all 3-4-5 of you drive F150s there?
We look exactly like the Simpsons before they nerfed the animation.
It means a group of people unlikely to be stopped and turned away at that gate. My assumption is white, middle class, dressed boring but clean, decent car without damage, with young kid(s), no/light tattoos, no motorcyckes in the back and no drug/booze/gun stickers or visible stuff. Basically someone the Karen's won't call to complain about.
Other people deserve access to public land too but might not pass the vibe check of the private guards, which is what op was lamenting as well.
That would be a typical f150 family. A typical suburban family travels in a convoy of chevy suburbans. A luxury suburban family travels in a convoy of escalades.
The F150s are too expensive now, so it's a convoy of Rangers or Mavericks (which honestly are better)
> but I imagine you'll regularly have people wander on to your property
Well, that depends on how large and obvious your property is.
Assuming you have a typical suburban 1/2 acre or 1 acre property, the simplest thing to do is put up a fence, or otherwise make sure that there are no trails that go over the property you use.
Otherwise, you need some kind of bounds marking and obvious "no trespassing" signs.
FWIW: The site identified public lands near my house that have a lot of trails on it. There are trails that go right behind peoples' yards, and most of them either have fences or sheds that make it obvious where the bounds are.
That is going to depend on location. Most public land is way way out. There are often only a handful of visitors per month, and most of them won't get close to your land. Most of them are locals who know where the bounds are (and probably know you)
That matches my experience next to state game lands in PA. There's a few hunters in season who know where the lines, especially with OnX, Mostly quiet the rest of the year.
It means that nobody can build more houses "up the road" from you. That's the primary benefit. Unless the government sells the land, which this government has been trying to do in various places. This one issue is responsible for much of the reduction in republican support in Montana, for example
If you want similar benefits in more urban environments, consider property next to a cemetery. The neighbors are quiet and the lot is very unlikely to be turned into a strip mall.
It seems to not find quite a few properties that border public land. For example, if I scroll around Zillow to find stuff that borders the Gifford Pinchot national forest, I can find properties like this one.[1] But I don't see anything matching it on the Unfenced map.
I bought 20 acres bordering the national forest a couple years ago. The seller made sure I had some idea of what I was getting into. Due to the isolation and terrain, everything is more difficult. It's been a lot of work to build a road, level an area to build on, construct a shed, and set up off-grid solar power. But it's also very rewarding. The views are spectacular, and at night you can see the milky way. There's still a lot more work to do before it's worthy of being called a vacation spot, but I'm very happy with my decision.
1. https://www.zillow.com/homedetails/Snag-Mountain-Rd-110-Wash...
This is super cool. I love this use of public data to do something cool. The page seems like it's biggest value is to help potential property buyers find property they wouldn't easily be able to otherwise (that's what I like about it). Given that, seems like being able to filter on cost and size of lot would be useful filters on top.
Very well executed and built ! Great example for what agentic coding can enable for projects run by someone with good 'taste' !
Thanks for sharing
Cool concept!
One big issue: not having a price and acreage range selectors means you see a lot of 0.2acre lots and $8mm parcels which I'm assuming most of us wouldn't be looking for
Very cool thought about something similar. How are you getting the data if you dont mind me asking?
Yes! As another Pennsylvanian, this is a hard requirement for my forever home. The idea that I’d go all-in on a large property in an undeveloped area, only for the surrounding land to get developed or demolished is scary. State game lands is a way to protect against that outcome.
Also a concern is proximity to fracking and now data centers. Not sure how to see if neighbors sold their underground…
As an anecdote, my parent’s home, where I grew up, is a small plot along my town’s watershed property. When the price of lumber went up recently, the town council conveniently remembered that the watershed property was once a massive “tree farm,” and since has leveled all of the surrounding woods. We never expected this. It has been emotionally crushing.
Gonna have the same "issue" with private lands. Over the 20+ years I owned a tree farm in rural Oregon, numerous of the nearby parcels were clearcut. This has benefits too. One day I was up on my ridge and was surprised to see a mountain I had never seen before because the ridge to the north was just clearcut.
Very cool project. One of my favorite Show HN posts. It’s interesting to see how hard it is to line up the maps from different sources, but in most cases it is close enough to dig further. A really useful tool. Thank you
Very cool! I would love the ability to search for land with or without a house, or at least to be able to sort by $ per acre.
Whoa, one of these is right up the road from a cannibal murder.
Small world.
I appreciate this OP
As somebody who is constantly looking for property adjacent to BLM this is a really good resource.
Edit: as of 1200ET the OP responding to me nicely is flagged/dead which is crazy. What is happening?
Thank you, that's great to hear. Honestly, the number of properties next to BLM was one of the things that surprised me most when I started building this, there's ~2,700 right now. On the map you can set the land type to BLM to see just those. And since you're always looking: any search can send you a weekly email when new matches turn up (starts Monday). Curious what else you check for on BLM-adjacent land?
*in the US only.
Did you exclude NPS units intentionally?
No, they're in. About 470 properties border or sit near NPS land (parks, monuments, recreation areas, lakeshores), e.g. a few along the edge of the Smokies. You're right that the headline copy only mentions national forest, BLM and state land, so that's misleading; I need to update the wording. The map's land-type filter has a "National Park Service" option if you want to see just those.
I don't see a single national park in California or Utah on those states' maps.
Feature request: near bike trail.
Good one, thanks. I think OpenStreetMap has decent bike-trail coverage, so "distance to the nearest trail" is quite doable. It's on the list.
It's showing me 3,200 acre "public land" near houses and it's just a real long trail ha!
Are you using this for parcel data? Or are you sourcing them directly from every county
https://www.kaggle.com/datasets/landrecordsus/us-parcel-laye...
Not that one. Parcels come from about 20 states' own statewide GIS services, and from Realie (licensed) for the rest. I'd want to check the license on that Kaggle dataset before using it, since county parcel data comes with all sorts of terms.
It would be nice to already see parts of the entire map coloured so you can see (extremely approximately) what's available.
I know some folks to have a cabin that they use seasonally that borders national forest land. First of all, it's gorgeous and being able to open their back gate and walk out into unspoiled wilderness is awesome. But it does have some drawbacks; their biggest "neighbors" are cattle ranchers who let their cows graze in the forest. The cows will often wander onto their property, and the cowboys are not shy about breaking fences or cutting wire to get their cattle back out. Since they're only there for part of the year, they've also had issues with hunters breaking the locks and using their cabin as a place to hang out while they're not there.
Surprisingly easy to manage, though. You'd think that things like propane delivery and septic system service would be hard to hire when you're miles out of town, up a steep logging trail, and across a home-made bridge, but the local businesses are used to it. I genuinely don't know how they find the place most of the time.
neat :)
Hi HN, I built this. Listings that say "borders state land" can't easily be checked: you open the county's GIS viewer and line up parcel lines against public-land maps by hand. I did that a lot while looking for land of my own, then automated it.
How it works, once a week:
1. About 700,000 active U.S. listings come in from a licensed listings API.
2. Each listing near public land gets its county parcel boundary, from state and county GIS services where they publish them and from a licensed parcel provider elsewhere. With no boundary, the page says so and measures from the listing point, but never claims a shared edge.
3. Public land is USGS PAD-US 4.1, narrowed to land an agency actually owns (Category = Fee, so no conservation easements), that's open to the public, and that's at least 50 acres.
4. Parcel and public land are compared in a local metric projection (shapely/geopandas): within (an inholding), bordering (the boundaries touch, and the shared edge is measured in feet), or adjacent (within 75 m, about a road's width).
Each property also gets the size of the connected public land behind it, its elevation (USGS 3DEP), road access (Census TIGER roads), FEMA flood zone and Forest Service wildfire hazard. The output is about 16,000 static pages with Leaflet maps on Cloudflare Pages, rebuilt every Monday on a Mac mini. ZIP search looks the ZIP up in your browser from Census centroids, so nothing you type is sent anywhere.
Things that were harder than expected:
- Lot sizes sometimes arrive in square feet in the acres field. A Birmingham, AL listing came through at 7,000 acres. Sizes are now checked against price, property type and the parcel itself, and corrected or withheld with a note.
- Condo and subdivision listings often resolve to the association's common tract, so a single town lot can appear to share miles of boundary. Those are flagged as shared parcels.
- PAD-US stores some units as one multipart polygon. My first "connected public land" figure for one Montana property was 69.7 million acres, about three-quarters of the state. Units are now split into pieces and joined only where they actually touch.
- Road centerlines and lot lines come from different agencies and are often tens of meters apart, so "does a road touch this parcel" needs a tolerance, and frontage only counts where the boundary runs along the road.
It's free, with no account and no cookies. There are free weekly email alerts for any search, starting Monday. I'd especially like to hear from anyone who has bought rural land: what should it measure that it doesn't?
> 1. About 700,000 active U.S. listings come in from a licensed listings API.
What API is that? It looks like you or the data broker are violating some NAR / MLS / State Compliance rules to me. You might want to look into those.
Not sure if you meant it that way, but this comes across as a bit hostile. Do you care to share some specific rules you think are being violated?
There are gazillion compliance laws, etc, but basic copyright laws commonly cover these things.
https://www.rentcast.io/terms-api

Database copyright isn't really a thing in the US.
It's RentCast (rentcast.io) listings API and parcel boundaries come from state/county GIS services and Realie (realie.ai). Fair question on the rules: I'm not a broker or MLS member, so NAR/MLS rules don't bind me directly; I license the listings through RentCast's API under terms that allow displaying them, and how they source the data is on their side. I also left agent phone numbers and emails out of the downloads on purpose so the site can't be used to build contact lists. If anyone from an MLS sees a problem with a specific listing, I'd genuinely like to hear about it: contact@unfenced.land
Which LLM did you use?
Mostly Claude Code. I have a background in 3D Design and Geospatial Mapping, the data sources and the decisions about what counts as "bordering" were mine
I'd love to chat to you about this. I have been solo building in the real estate space for about 5 years now. I've finally got to a point where I make a roughly market salary from it, and I'm starting to venture wider into providing a listing service for everyone from FSBO's to large brokerages. Theres a huge opportunity to displace the position Zillow et al have, but it's riddled with legal challenges and risk (They've done a great job of making it hard to break in).
If you're up for a chat, please ping me! This is pretty cool and I'm wondering if theres a collaboration, or if I can straight up use some of what you've made.
