Squatters in California: What Property Owners Can Do
Squatters in California are one of the most stressful problems a property owner can face. You find out someone is living in a vacant house you own, maybe an inherited home or a rental between tenants, and suddenly you’re dealing with police, paperwork, and a lot of uncertainty. The good news is that California law gives owners a clear legal path. The hard part is that the path takes patience.
We’ve been buying houses in California since 2003, including many vacant and inherited homes, so we’ve seen how these situations unfold. We’re not attorneys, and squatter cases can turn on small details, so please talk to a California landlord-tenant or real estate attorney about your specific situation. Here’s a plain-English overview.
Squatter, Trespasser, or Tenant?
These words get mixed up, but the difference matters because it can change how the situation is handled.
- Trespasser: someone who enters or stays on property without permission and hasn’t established any kind of residence. Trespassing is generally a criminal matter, and police can often act.
- Squatter: someone living in a property without the owner’s permission who has moved in, perhaps with belongings, utilities, or a claim that they were allowed to stay. Once someone appears to be living there, police often treat it as a civil matter.
- Tenant or former tenant: someone with a lease or other agreement, even an expired or informal one. Tenants have strong legal protections in California, and removing them follows a formal eviction process.
Sometimes a squatter presents a fake lease or says a relative of the owner let them in. Police in the field usually can’t sort out who is telling the truth, which is why many of these cases end up in court.
What About “Squatters’ Rights” and Adverse Possession?
You’ll see a lot online about “squatters’ rights.” In California, the legal concept is called adverse possession, and it is very hard for a squatter to use it to take ownership. Generally, a person would have to occupy the property openly and continuously for five years, without the owner’s permission, and pay the property taxes during that time, along with meeting other legal requirements. Because owners are usually the ones paying the property tax bill, successful adverse possession claims against a house are rare.
So the real risk for most owners isn’t losing the house. It’s the time, cost, and damage while someone is living there without permission.
How Squatters Are Typically Removed in California
Every case is different, but the general steps often look like this:
- Call the police right away. If you catch it early, before someone has established residence, police may be able to treat it as trespassing. Bring proof of ownership, like a deed or property tax bill.
- Ask about a trespass authorization letter. Many California police departments let owners of vacant property file a letter authorizing officers to act on trespassers. Ask your local department what they accept.
- If police say it’s a civil matter, talk to an attorney. The usual next step is an unlawful detainer case, the same type of court case used for evictions. It involves serving notice, filing with the court, and, if you win, having the sheriff carry out the removal.
- Document everything. Take photos, keep records of utility accounts, and save any communication.

What Not to Do
It’s natural to want to handle it yourself, but “self-help” can backfire. Changing the locks while someone is living there, removing their belongings, shutting off utilities, or using threats is generally not allowed and can expose you to legal liability, even if the person has no right to be there. Let the legal process do the work.
How to Prevent Squatters in a Vacant House
Vacant homes are the most common target, especially during probate or between tenants. A few steps can help:
- Make the house look lived in: keep the yard maintained, stop mail and flyers from piling up, and use timers on lights.
- Secure every entry, including back doors, garages, and crawl space vents.
- Visit regularly or ask a trusted neighbor to keep an eye out and call you, not just the police.
- Post no trespassing signs and keep your trespass authorization letter on file with the police.
- Check your insurance. Vacant homes often need a different policy, and some standard policies limit coverage after a home has been vacant for a while.
If the house is part of an estate, our guide on how to sell an inherited house in California covers how to protect and sell a vacant property while the paperwork is handled.
Can You Sell a House With Squatters in It?
Sometimes, yes, but it’s complicated. Most traditional buyers and lenders want the home delivered vacant, and showings are difficult or impossible with someone living there. Some investors will consider buying an occupied property, but each situation is different.
For us, buying a house with someone living in it is case by case. California occupancy situations can be difficult, and we look at the details before saying whether we can help. We won’t promise to handle a removal for you. In some cases, owners work with an attorney to resolve the occupancy first, sometimes with a negotiated move-out agreement, which our article on cash for keys in California explains. If the occupant is actually a tenant, see our guide to selling a tenant-occupied property in California.
When Selling Right Away Isn’t the Best Option
If the squatter situation is likely to be resolved soon through the court process, and the house is in good shape otherwise, it may make more sense to wait until the property is vacant and then decide how to sell. A vacant, secured home usually gives you more buyers and more options. Selling quickly tends to make the most sense when the house also needs major repairs, you’re managing it from far away, or the costs of holding it are adding up.
Frequently Asked Questions
Generally, adverse possession in California requires at least five years of open, continuous occupation without permission, plus payment of the property taxes during that time and other legal requirements. Successful claims against houses are rare, but talk to an attorney if someone is making one.
Sometimes. If someone has just entered and hasn’t established residence, police may treat it as trespassing. Once a person appears to be living there or shows a document claiming permission, police often consider it a civil matter that has to go through the court process.
That is generally not allowed in California and can create legal liability for you, even if the person has no right to be there. Use the legal process instead, and talk to an attorney before taking action.
It depends on the facts, the county, and whether the case is contested. A court case can take weeks to months. Acting quickly and keeping good documentation can help.
