To spot a squatter, look for changes you didn’t authorize and signs of daily life on a property that should be empty: new locks, utility meters running, unfamiliar vehicles that keep coming back, curtains in previously bare windows, and mail addressed to people you don’t know. Squatters rely on being noticed late. The earlier you catch them, the cheaper and faster removal becomes.
Check the Doors, Windows, and Exterior First
The exterior tells you most of what you need to know without stepping inside.
Start with the locks. If the deadbolt on your property has been changed and you didn’t authorize it, that is the single strongest indicator someone has moved in. Look closely at the door frame and strike plate for fresh scratches, replaced screws, or mismatched hardware. New doorknobs, added deadbolts, and padlocks on sheds or garages all suggest someone is securing the place for themselves.
Windows come next. Broken panes taped over or covered with cardboard from the inside point to a break-in followed by an attempt to make the space livable. Plywood screwed over a window from the inside, rather than the outside where an owner would typically board up, is a giveaway. Also check for windows that are now unlocked or slightly ajar when you know they were secured.
Other exterior changes are easier to miss. A new mailbox, an unfamiliar name on the existing one, or mail that’s been neatly collected rather than piling up all suggest someone is intercepting deliveries. Fences or gates that appeared without your knowledge, especially around a backyard or side entrance, indicate someone trying to create privacy. Landscaping cuts both ways: a suddenly mowed lawn on a property you haven’t maintained means someone wants the place to look occupied and legitimate, while a lawn deteriorating faster than expected can point to foot traffic from an entrance you haven’t noticed.
Signs Someone Is Actually Living Inside
Physical alterations show that someone got in. These signs show that someone stayed.
Utility usage is the most objective evidence you’ll get. If you still have accounts active on the property, check your water, electric, and gas meters. Consumption on a vacant home is hard to explain away. If utilities were shut off, watch for evidence that someone has reconnected them, either through the utility company under a fraudulent identity or by rigging a direct connection. Unexplained utility bills arriving at the property address are a clear red flag.
Habitation is often visible from the sidewalk. Curtains or blankets hung in windows that were previously bare, furniture behind the glass, condensation on windows in cold weather from body heat or cooking, and the glow of lights or a television at night all confirm someone is inside. Trash bags set out on collection day, recycling bins appearing at the curb, and food delivery bags near the door show a daily routine.
Pay attention to mail. Envelopes addressed to people you don’t recognize, packages on the porch, and flyers stuffed in a door that disappear between visits all confirm regular presence. Some squatters file a change of address form with the postal service, which can cause your own forwarded mail to stop arriving.
Activity Patterns to Watch For
A property you believe is vacant should have no routine. When it develops one, pay attention.
Unfamiliar vehicles parked consistently in the driveway or on the street nearby are among the first things neighbors notice. The key word is “consistently.” A car parked there once could be anyone. The same car every night, or a rotation of the same two or three vehicles, points to someone living there. The absence of a moving truck is itself a clue: squatters typically move in with whatever fits in a car, not a professional haul.
People coming and going at irregular hours, particularly late at night and early morning, suggest habitation rather than a one-time trespass. Sounds from inside, whether music, voices, television, or the hum of appliances, confirm someone has settled in. The smell of cooking is one of the most commonly reported signs by neighbors.
Toys in the yard, a dog tied up outside, bicycles against the house, and school-age children coming and going on weekday mornings are hard to miss. Courts are generally more cautious about ordering removal when children are present, which is one more reason to catch the situation early.
Neighbors are your best surveillance system. If you own a property you don’t visit regularly, one trusted neighbor with your phone number who knows the place should be vacant is worth more than most security technology. Ask specific questions rather than vague ones. “Have you noticed anything unusual?” gets a shrug. “Have you seen anyone going in or out, or lights on at night?” gets useful answers. Ask about vehicles, delivery drivers, and whether trash has been set out on collection days. Neighbors can also give you a rough timeline of when activity started, which matters for the legal case later.
When a Squatter Produces a Fake Lease
A growing number of squatters skip the break-in entirely and fabricate paperwork. They show up with a lease, sometimes listing the correct property address and owner name pulled from public records. When police arrive, the person waves the document and claims to be a paying tenant. That piece of paper, even an obvious forgery, can be enough to turn what should be a trespassing removal into a months-long eviction case.
The fastest way to check a suspicious lease is to compare the landlord name on it against public property ownership records, which are available online through most county assessor or recorder offices. If the name doesn’t match the actual owner, the document is fraudulent. Other red flags include no specific start or end date, missing signatures, rent that doesn’t match the local market, and agreements printed on plain paper with no letterhead or contact information.
Several states have recently made it a criminal offense to present a forged lease or deed to law enforcement or a property owner, with penalties ranging from misdemeanor charges to felony fraud. If someone at your property produces a lease you didn’t authorize, don’t argue about its validity on the spot. Document it, photograph it if you can, and bring it to court where a judge can examine it properly.
Document Everything Before You Act
Once you suspect a squatter, the instinct is to act immediately. Document first. The evidence you gather now determines how quickly you can get the person out through legal channels.
Photograph every sign of unauthorized occupation from the exterior: changed locks, broken windows, new items on the property, vehicles with visible license plates, trash, and any personal belongings visible from outside. Take video if you can. Make sure your phone’s location services and automatic timestamps are turned on so every image is geotagged and dated. Courts give more weight to evidence with clear timestamps.
Keep a written log with dates and times of every visit, every observation, and every interaction. Note what you saw, heard, and smelled. If neighbors provide information, write down what they told you, when they told you, and what dates the activity they described occurred. Save copies of any utility bills, and request usage history from your utility provider showing consumption during periods the property should have been vacant.
Do not enter the property to gather evidence. If the squatter has established any claim to occupancy, entering without following proper legal procedures can undermine your case and potentially expose you to liability. Everything you need for the initial police report and court filing can be gathered from the outside and from records.
Why Speed Matters
Early detection isn’t only about property damage. The legal position shifts against you the longer a squatter stays.
Every state recognizes some form of adverse possession, a doctrine that allows someone who occupies property openly, continuously, and without permission to eventually claim ownership. The required time period varies widely, from as few as three years in some states to twenty or more in others. The possession must be open and obvious, hostile to the true owner’s rights, continuous without significant gaps, exclusive of others, and actual rather than theoretical. Some states also require the squatter to have paid property taxes during the occupation period. A squatter who knows the rules will deliberately check these boxes from day one.
The more immediate risk is that many jurisdictions treat long-term occupants, including squatters, as having tenant-like protections once they’ve been in place for a certain period. When that happens, you can’t simply call the police and have them removed as trespassers. You’re forced into a formal eviction process that can take weeks or months and costs money in filing fees, service fees, and potentially attorney fees. A handful of states have recently passed laws that explicitly declare squatters are not tenants regardless of how long they’ve been on the property, and some now allow law enforcement to remove unauthorized occupants without a court order if the property owner provides a sworn affidavit. These reforms are not universal, and in most places delay still favors the squatter.
What to Do Once You’ve Confirmed It
This is where property owners make the most expensive mistakes. The urge to change the locks, shut off the water, or haul the squatter’s belongings to the curb is understandable. Do none of these things. Nearly every state prohibits self-help eviction, meaning you cannot remove an occupant by force, intimidation, or cutting off utilities, even if they have no legal right to be there. Violating that prohibition can result in the squatter suing you for damages, and some jurisdictions treat it as a criminal offense.
Follow this sequence instead:
- Call police and file a trespassing report. Whether police can remove the squatter on the spot depends on your state’s laws and whether the squatter claims to be a tenant. Even if officers say it’s a civil matter, the report itself becomes evidence for your court filing.
- Consult a local attorney. Eviction procedures, timelines, and notice requirements vary enormously by jurisdiction. Someone who handles landlord-tenant or property disputes in your area can tell you exactly what process applies.
- Serve proper legal notice. In most states, you’ll need to serve the squatter with a written notice to vacate before you can file for eviction. The required notice period ranges from a few days to thirty days depending on local law.
- File for eviction if the squatter doesn’t leave. Court filing fees generally run between $50 and $300. A process server to deliver legal papers adds $30 to $150. The timeline from filing to court-ordered removal typically takes several weeks at minimum.
Keep documenting throughout. Judges resolve disputed claims based on evidence, and the owner who shows up with a thick folder of timestamped photographs, utility records, and neighbor statements gets a faster ruling than the one who shows up with a story.
Making Your Property a Hard Target
Squatters pick the easiest option available. Modest security measures push them toward someone else’s property.
- Visit regularly. A property that gets checked weekly or biweekly is far less attractive than one that sits untouched for months. If you can’t visit in person, hire a property manager or ask a neighbor to walk the perimeter.
- Make it look occupied. Timed interior lights, maintained landscaping, an occasional car in the driveway, and regular mail collection all suggest someone is paying attention.
- Secure every entry point. Deadbolts on all exterior doors, window locks, and secured garage doors are baseline. Smart locks let you monitor access remotely and receive alerts if a lock is tampered with.
- Install visible cameras. Security cameras with remote monitoring let you check on the property from your phone and act as a deterrent. Pair them with signage indicating the property is under surveillance.
- Keep utilities in your name. Active accounts show usage spikes immediately. If utilities are shut off, someone attempting to activate them under a different name creates a paper trail.
The owner who checks regularly, documents thoroughly, and acts through legal channels gets the property back. The owner who ignores the warning signs or tries to handle it alone almost always pays more in time, money, and damage than the situation required.
