Someone Built on My Property Without Permission: What to Do Now

If a fence, a shed, a driveway, or something bigger has crossed onto your land, the clock matters more than you might think. Left alone long enough, an encroachment can actually mature into real legal rights for the person who built it. Staying quiet isn’t a neutral choice here — it’s a position, and it’s the losing one. That’s the honest reason to act now, not a scare tactic.

What Not to Do First

Before anything else, avoid two mistakes that make this worse, not better.

• Don’t demolish, remove, or damage the structure yourself, however clearly it’s on your land. Self-help removal exposes you to real liability and can turn a strong position into a countersuit against you — this is the single most expensive mistake available here.
• Don’t accept payment from the neighbor or give them written permission without understanding what that does. Permission can actually work in your favor, since it defeats a future claim that they earned rights through continued use — but a poorly worded agreement can also accidentally create a recorded easement you can’t take back.

What to Do Instead

• Document everything now — dated photographs, when construction started, any conversations you’ve already had with the neighbor about it.
• Get a current boundary survey before you assert anything in writing or in person. Sending a demand letter and then discovering you were wrong about your own line is a genuinely bad place to be.

Does It Matter How Big the Encroachment Is?

Yes, quite a bit. A fence line, a shed corner, or a driveway apron a foot or two over the line is a very different situation than a neighbor’s garage, barn, or part of a house foundation sitting on your land. And something that isn’t a structure at all — fill dirt, a graded road, cleared timber, a lawn someone’s been mowing and maintaining — can still count, and timber cutting specifically can carry its own separate, often severe damages in many states. The remedy that makes sense scales with what’s actually involved.

Why a Court Might Not Just Order It Removed

Here’s something worth knowing before you spend money pursuing a teardown: courts don’t always order an encroachment removed, even when they agree it’s genuinely on your land. Many states recognize some version of what’s often called the relative hardship doctrine — if the encroachment was innocent (not deliberate), and tearing it down would cost the other side far more than the harm it’s actually causing you, a court can decline to order removal and award you money damages instead, or in some cases force a sale of the strip of land involved. This varies significantly by state and by the specific facts, and it’s exactly the kind of thing a real property attorney should assess for your situation before you set your expectations on a guaranteed teardown.

Realistic Paths Forward, Roughly Cheapest First

• A conversation, followed by a written and recorded boundary line agreement both sides sign, fixing the line where you actually agree it sits.
• Selling the encroached strip to the neighbor outright — often the cleanest outcome when the structure is permanent and the strip of land involved is small. This generally requires a formal lot split first.
• A license or recorded easement letting the structure stay on specific, written terms, with an explicit statement that it’s permissive, not a transfer of ownership.
• Ejectment or a mandatory injunction, asking a court to compel removal.
• A quiet title action, if the encroacher is actually claiming ownership of the land itself, not just using it.

This is the first-person version of a broader topic — for the full picture on boundary and encroachment issues generally, see the Encroachments guide in our Problem Land Encyclopedia.

If You’re Trying to Sell the Land

An encroachment is one of the more common reasons a survey kills a deal late in the process — it will surface in a buyer’s title work whether you disclose it upfront or not, so disclosure is the sound approach either way. If this is exactly what happened to you, our guide on a buyer backing out after a survey covers what comes next.

Common Questions

Can I just tear it down myself since it’s on my land?

No — don’t. Self-help removal can expose you to real liability, even when you’re right about the boundary. Document it and get a survey instead.

How long before this becomes a real legal problem for me?

It varies by state, but continued, open use of your land without objection can eventually mature into real legal rights for the person using it. Don’t assume you have unlimited time to decide.

If I let them pay me, does that fix it?

It can help — permission generally defeats a future claim that they earned rights through use — but get it in writing carefully, with help, since a poorly worded agreement can unintentionally create a recorded easement.

Will a court definitely order it removed?

Not necessarily. Many states recognize a balancing test that can result in money damages instead of removal, particularly for an innocent, costly-to-remove structure. An attorney can tell you what’s realistic for your situation.

What if it’s not a structure, just cleared land or a maintained lawn?

It can still count, and if timber was cut without permission, many states impose separate, sometimes substantial damages for that specifically.

Dealing With an Encroachment and Ready to Sell Instead?

If the land is 10+ acres and sorting this out with a neighbor isn’t something you want to take on, you don’t need it resolved first. Tell us about the property and the situation, and we’ll let you know whether a direct offer makes sense — this isn’t a legal opinion, and not a guarantee of an offer.

Important disclosure

Sell My Vacant is a direct land buyer, not a law firm or surveying firm. Nothing on this page is legal or survey advice. Adverse possession, prescriptive easement, and relative hardship rules vary significantly by state and by the specific facts involved. Consult a real property attorney and a licensed surveyor before taking action.
