"Squatters Rights" in California — Mostly a Myth, Practically a Problem

The contrarian fact

The "squatter takes your house" story you see on social media is misleading. California's adverse possession framework (CCP §318-§325) requires every element of a high bar to be met for five continuous years, including payment of the property taxes by the squatter. Almost no squatter pays property taxes — that line on a tax assessment is one of the cleanest reasons most adverse possession claims fail outright.

What's actually true: removing a squatter takes more procedural steps than removing a trespasser, because California treats the squatter as a tenant-at-sufferance for procedural purposes. The path is unlawful detainer, not self-help. That's where most owners get frustrated.

The actual adverse-possession elements

Under California case law applying CCP §318-§325, a successful adverse possession claim requires:

• Open and notorious possession (visible to the owner and the public).
• Hostile — without the owner's permission.
• Continuous for at least 5 years.
• Exclusive — the claimant alone, not shared with the owner or public.
• Payment of all property taxes during the 5-year period (CCP §325).
• Color of title or claim of right.

The tax payment requirement is the bright line. A squatter who hasn't paid five years of property taxes loses on summary judgment. Owners who keep paying their taxes have nearly absolute protection against adverse possession.

Removing a squatter — the UD path

California courts treat squatters as tenants for procedural purposes once they've been in place long enough to claim color of right. The removal path:

1. Serve a written demand to vacate. Typically a 3-day or 30-day notice depending on the specific circumstances. For an unlawful occupant (no lease, no permission, no relationship), 3-day notice to quit is common.
2. Wait the notice period. Don't go in.
3. File unlawful detainer. In Superior Court for the county.
4. Serve summons and complaint. Through a process server or sheriff.
5. Trial. Squatter has the response window under AB 2347 (10 court days). Bench trial follows.
6. Writ of possession. Sheriff lockout.

When the police can help

Penal Code §602 criminalizes forcible entry to property. When a squatter has just broken in — days, not months — police in many California jurisdictions will treat it as a criminal trespass and remove the person. The longer the squatter has been in place, the more police treat it as a civil matter. The cutoff varies by department; some agencies are more willing to act than others.

Documentation that helps police get involved: evidence of recent forcible entry (broken lock, damaged door), evidence of legitimate ownership (deed, tax records), and the absence of any utility setup in the squatter's name.

Prevention

• Don't leave units vacant for extended periods without inspection.
• Drive by vacant properties weekly. Check for changed locks, occupancy signs, mail buildup that suddenly stops.
• Keep property taxes paid. The tax-payment bar is the cleanest protection.
• Address breaks-in immediately. Same-day police report; same-week UD filing if the person doesn't leave.
• Camera surveillance on vacant properties is legal in California for owner's own property.
