If you’ve found homeless camping on private property you own, the lawful path forward runs through documentation, posted notice, and law enforcement — not through anything you do with your own hands. Every state prohibits some form of “self-help” removal, and the shortcuts that feel most satisfying in the moment are the ones most likely to turn you from the injured party into a defendant.
Don’t Try to Remove Anyone Yourself
Tearing down a tent, throwing belongings into the road, cutting tent lines, padlocking access points people have been using, or turning on sprinklers to drive occupants out are all off limits. These actions can expose you to civil liability for property destruction and, depending on how aggressive things get, criminal charges for assault or harassment.
The reasoning is simple. The legal system requires removal of people from any location to go through a process with built-in safeguards. Bypassing that process can undermine your own position if the situation later reaches a courtroom, because a judge may treat your conduct as the more serious wrong. Physical confrontation also carries real safety risk that no property interest justifies.
Photograph and Log Everything Before You Do Anything Else
Spend ten minutes building a record before you make a single call. Use your phone to photograph the encampment from a safe distance, capturing its location relative to your property lines, the number of structures, and any visible damage to the land. Take video if the scene is large or complex. Write down the date and time of each observation.
Photographs taken before any removal establish the baseline if you later pursue civil damages for cleanup costs or property repair. Timestamped evidence of a measured approach also helps if a dispute arises over whether you followed proper procedures. Keep everything organized in a folder or album you can hand to a lawyer or officer.
Post No-Trespassing Notice
Posting your property puts occupants on notice that they’re unwelcome and strengthens any future trespass claim. Criminal trespass laws in most states require the prosecution to show that a person was “forbidden” to enter or remain, either through direct communication or posted notice. Without signs, fencing, or a verbal warning, proving that element gets harder.
Place signs where anyone approaching would reasonably see them. “No Trespassing” or “Private Property — No Trespassing” in clear, legible lettering is standard. Requirements for sign size, spacing, and placement vary by jurisdiction, so check local ordinances. Some areas require signs at every entry point; others accept them at regular intervals along the boundary.
More than 20 states now recognize “purple paint laws,” which let landowners mark trees or posts with vertical purple paint stripes as a legal substitute for traditional signs. The marks must meet specific dimensions and spacing requirements that differ by state. This option is useful for rural landowners with large tracts where signs would be impractical or easily stolen.
Call the Police and Ask About Trespass Authorization
Call the non-emergency line to report the trespass. Reserve 911 for an active crime, medical emergency, or immediate safety threat. Give the dispatcher your name, the property address, and a clear statement that you are the owner reporting unauthorized camping. Mention that no-trespassing signs are posted, how many people appear to be present, and any structures you’ve observed.
Responding officers will typically make contact with the occupants, tell them the land is private, and give them a window to leave voluntarily. If they refuse, officers can issue a trespass citation or, in some jurisdictions, make an arrest. Your role during this is to be available and cooperative, not to direct the operation. Police handle the interaction; you provide the authorization and answer questions about ownership.
Trespass Letter of Consent
Many police departments offer a program sometimes called a Trespass Letter of Consent or trespass authorization. You sign a document giving officers standing permission to enforce trespass laws on your property without needing to reach you first. This matters if you don’t live near the property or can’t respond quickly when a new encampment appears. Ask your local department whether they offer this. With the authorization on file, officers can act immediately when they encounter someone on your posted land instead of waiting to confirm your wishes each time.
When People Return
If occupants return after being removed, document each new encampment the same way you documented the first. Repeated trespass strengthens any civil case you may bring and can escalate the criminal charge in some jurisdictions. Keep a log of every incident with the date, the responding officer’s name, and any case or report numbers.
Never Accept Money From Someone Camping on Your Land
This is the trap that blindsides property owners. Someone who started as a trespasser can argue they’ve become a tenant, meaning they can’t be removed without formal eviction proceedings. Courts in many states will entertain that argument, particularly when the occupant has been on the property for an extended period, has received mail there, or when the owner has accepted any form of payment.
The line between a trespasser and someone with a tenancy claim varies by state. As a general rule, if money changed hands or any written agreement exists (even an informal one), the occupant will likely be treated as a tenant rather than a trespasser. If neither happened, the person is a squatter, and removal usually follows an unlawful detainer action rather than a standard eviction.
The practical rule is straightforward: never accept money from someone camping on your property, even if they offer it as “rent” or as compensation for the inconvenience. Accepting payment can create a month-to-month tenancy that triggers full eviction protections. Act promptly, because the longer occupants remain undisturbed, the stronger any argument about implied permission becomes.
What to Do With Belongings Left Behind
After occupants leave or are removed, you’ll almost certainly find belongings scattered around the site. You cannot simply throw everything away. Most states impose a duty to store abandoned personal property for a set period and to make a reasonable effort to notify the former occupants before disposing of it.
The typical process:
- Inventory and photograph every item you find. This protects you if someone later claims you destroyed something valuable.
- Move belongings to a dry, accessible location. You don’t need to rent a storage unit, but leaving things in a pile exposed to weather won’t satisfy a court.
- Post a written notice at the former site describing the items, where they’re stored, and a deadline to retrieve them. Many jurisdictions require this.
- Wait out the deadline. Storage periods typically range from about 7 to 30 days depending on your state. After the deadline passes without a claim, local law governs whether you can discard, donate, or sell the items.
Some categories of belongings receive special protection. A number of states exempt medically necessary items, tools of a trade, and basic clothing from storage liens, meaning you may have to release those items on demand even before the deadline expires. Skipping any part of this process exposes you to a conversion claim, essentially the civil equivalent of theft, which can result in money damages even if the items had little value.
Cleanup and Biohazards
The cost of cleaning up an encampment catches most owners off guard. Beyond ordinary trash removal, you may face biohazard concerns that require professional remediation. Sites frequently contain human waste, discarded needles, and other materials that pose genuine health risks. OSHA regulations treat all human body fluids as potentially infectious, and contaminated sharps like needles must not be bent, recapped, or handled without proper protective equipment.1Occupational Safety and Health Administration. Bloodborne Pathogens – 1910.1030
Professional biohazard cleanup for even a modest site can run from roughly $1,500 to $5,000 or more, depending on size and severity of contamination. General debris removal adds to that. Before you or anyone else sets foot on the former encampment, do a visual sweep for needles, broken glass, and waste. If you see any of that, bring in professionals rather than handling it yourself.
Check whether your homeowner’s or commercial property policy covers any portion of cleanup. Some policies treat encampment damage as vandalism, which may be covered; others exclude it. Contact your insurer before incurring expenses so you know what documentation they’ll need.
What You Owe a Trespasser Who Gets Hurt
Property owners are often surprised to learn they can be sued by someone who was trespassing on their land. The bar for such claims is high. Under long-standing tort principles, a landowner generally owes trespassers no duty to keep the property safe or warn of hazards. A trespasser enters at their own risk. Liability attaches only when the owner does something willful or reckless, meaning a deliberate act or an extreme disregard for safety, not just a failure to maintain the property.2Cornell Law School Legal Information Institute. Trespass
The clearest way to cross that line is to set a trap. Booby-trapping your property to injure trespassers is illegal everywhere in the United States. Even if someone has no right to be on your land, deliberately creating a hazard designed to hurt them makes you liable for their injuries and potentially subjects you to criminal charges. Trip wires, concealed pits, rigged doors — any of that will land you in far more trouble than the trespassers ever caused.
There’s a wrinkle for known trespassers. Once you’re aware people are camping on your property, your duty of care edges upward. If you’ve created or maintained an artificial condition on the land that you know could cause serious injury or death, you may need to take reasonable steps to warn trespassers you know are present. That doesn’t mean making your property safe for them. It means you can’t, for example, leave an open pit next to their encampment and say nothing.
Suing for Damage and Getting an Injunction
Beyond having people removed, you can pursue civil action for the damage they’ve caused. Trespass is both a crime and a tort, meaning you can seek money damages in court independent of any criminal prosecution. Available remedies include compensatory damages to cover the cost of repairing your property and restoring it to its pre-trespass condition, as well as recovery for lost use or diminished market value.
If the trespass was particularly egregious, involving deliberate destruction, threats, or refusal to leave despite repeated warnings, some jurisdictions allow punitive damages. A few states provide statutory damages, such as double or treble recovery, for specific types of trespass like cutting down trees. You can also seek an injunction, a court order prohibiting the individuals from returning. Injunctions are especially useful against repeat trespassers, because violating one is contempt of court.
The practical challenge with civil suits against unauthorized campers is collection. A judgment is only as good as the defendant’s ability to pay. For many owners, the real value isn’t the money — it’s the injunction and the formal legal record that strengthens your position if the problem recurs.
