You can remove someone from your house in California, but the method depends entirely on whether the law treats that person as a guest or a tenant. A guest who refuses to leave is trespassing, and police can escort them out. A tenant, even one with no lease and no rent payments, has legal protections that require you to go through a formal eviction, which the courts estimate takes 30 to 45 days or longer from the first notice to the sheriff’s lockout.1Judicial Branch of California. The Eviction Process for Landlords Getting that distinction wrong, or skipping steps, can turn you into the defendant.
Is the Person a Guest or a Tenant
This is the question that decides everything else. A guest stays with your permission and can be asked to leave whenever you say so. A tenant has established some form of residency, which triggers protections against removal even without a written lease and even without rent.
California courts look at the full picture. Factors that push someone toward tenant status include:
- Paying toward rent, utilities, groceries, or any household expense that could be read as rent.
- Receiving mail at the address.
- Having a key and coming and going independently.
- Moving in furniture or a meaningful amount of personal belongings.
No single factor automatically creates a tenancy, and there’s no bright-line rule that says “after 30 days you’re a tenant.” But the longer someone has stayed and the more they’ve integrated into the household, the more likely a court is to call them a tenant at will. An adult child who has lived in the home for months, or a partner who moved in and started chipping in on bills, will almost always be treated as a tenant, whether or not anyone ever used the word “rent.”
Removing a Guest Who Won’t Leave
If the person is genuinely a guest with none of the tenancy indicators above, this is straightforward. Tell them, clearly, that they need to go. Once a guest refuses to leave after you’ve revoked permission, they’re trespassing under California Penal Code 602, which covers refusing to leave private property after the owner asks.2California Legislative Information. California Penal Code Section 602
Then call local law enforcement. When officers arrive, they’ll size up whether the person is really a guest or has established some form of tenancy. If it’s clearly a guest, they can remove the person without a court order. The catch: if the person tells officers they’ve been living there, receive mail there, or contribute to household costs, police often back off and call it a civil matter, which sends you into the eviction process anyway. That’s why the guest-versus-tenant analysis matters so much before you dial.
Evicting Someone Who Qualifies as a Tenant
If the person is a tenant, you can’t call the police, you can’t change the locks, and you can’t move their things to the curb. You have to work through the statutory process, and every step has to be done correctly.
Step One: Serve a Written Notice
Eviction begins with a written notice. Which one you use depends on the situation:
- A 30-day notice to quit, if the tenant has lived there less than a year.3Judicial Branch of California. Types of Eviction Notices Landlords
- A 60-day notice to quit, if the tenant has lived there one year or more.3Judicial Branch of California. Types of Eviction Notices Landlords
- A 3-day notice to pay rent or quit, if the tenant owes back rent. The notice can list only past-due rent, not late fees, not utility charges, not bounced-check fees. If it demands more than what’s actually owed, it’s invalid.4Judicial Branch of California. Types of Eviction Notices Tenants
Every notice needs the tenant’s full name, the property address, and the date they have to leave. For the 3-day notice, count only court days — Saturdays, Sundays, and court holidays don’t count, and day one is the first day after the tenant receives it.4Judicial Branch of California. Types of Eviction Notices Tenants
Delivery matters too. California recognizes three methods, and you have to try them in order: personal service (handing the papers directly to the tenant); substituted service (leaving them with another adult at the home or workplace and mailing a copy) if personal service fails; and posting and mailing, which requires a judge’s permission after the first two methods have failed.5California Courts.

Step Two: File an Unlawful Detainer Case
If the tenant doesn’t leave by the deadline in the notice, you file an Unlawful Detainer lawsuit in the superior court of the county where the property is located. You cannot file before the notice period fully expires. Jumping the gun invalidates the case and you’ll start over.6Judicial Branch of California. Fill Out Forms to Start an Eviction Case
Once you file, the tenant has to be formally served with the court papers. They then have ten court days to file a written response.7California Legislative Information. California Code of Civil Procedure CCP 1167 Because court days exclude weekends and judicial holidays, that’s roughly two calendar weeks. If they don’t respond, you can ask the court for a default judgment. If they do respond, either side can request a trial, which the court must hold within 20 days of the request.8California Legislative Information. California Code of Civil Procedure CCP 1170.5
Contested cases, especially where the tenant raises defenses like habitability problems or retaliation, run longer than the 30-to-45-day baseline. Budget for filing fees, a process server, and possibly an attorney if the case goes to trial.
Step Three: The Sheriff’s Lockout
Winning the case doesn’t mean you can change the locks that afternoon. After the court enters judgment for you, file a Writ of Execution with the clerk and take it to the sheriff’s office.9California Courts | Self Help Guide. After the Eviction Trial Decision
The sheriff serves the tenant a Notice to Vacate that gives them five days to move out. If they’re still there when that deadline passes, the sheriff returns, physically removes them, and locks them out.9California Courts | Self Help Guide. After the Eviction Trial Decision Until the sheriff performs the lockout, the tenant has a legal right to remain. Only after the lockout is the eviction complete.
One more thing after the lockout. If the former tenant left belongings behind, you can’t just throw them out. California requires a written notice describing the property and giving the tenant a deadline to reclaim it, generally 15 days for personal delivery or 18 days if mailed. Skipping this step exposes you to a separate lawsuit for the value of what you tossed.
What You Cannot Legally Do
California strictly prohibits “self-help” eviction. No matter how fed up you are, you can’t force a tenant out by making the home unlivable. The law bans:
- Changing the locks or installing any device that keeps the tenant out.
- Removing the tenant’s belongings without their written consent.
- Shutting off utilities like water, gas, or electricity.
- Removing doors or windows to make the home uninhabitable.10California Legislative Information. California Code CIV 789.3
Penalties stack. Civil Code 789.3 makes you liable for the tenant’s actual damages plus up to $100 for every day you’re in violation.10California Legislative Information. California Code CIV 789.3 Civil Code 1940.2 adds up to $2,000 per violation for using threats, force, intimidation, or immigration-status threats to push a tenant out.11California Legislative Information. California Civil Code Section 1940.2 Those penalties run on top of any damages in the tenant’s own lawsuit, and an illegal lockout can torpedo your pending eviction case.
A Faster Route When There’s Abuse
If the person you want out has been violent or threatening toward you or your family, eviction is not your only option, and it’s probably not the fastest one. California allows victims to seek a Domestic Violence Restraining Order, which can order the abuser to leave the shared home immediately.12Judicial Branch of California. Domestic Violence Restraining Orders in California
You file the request at the courthouse. A judge can issue a temporary restraining order the same day, without the other person present, and that order can include a move-out. A hearing for a longer-term order is then scheduled within about three weeks. This route applies when the person is a spouse, a domestic partner, someone you’ve dated, a co-parent, or a close relative. If you’re in immediate danger, call 911. Officers can request an Emergency Protective Order from a judge by phone that takes effect right away and lasts up to seven days.
If the Person Is Active-Duty Military
One boundary worth knowing. If the person you’re trying to remove is an active-duty servicemember, federal law adds a layer on top of California’s process. The Servicemembers Civil Relief Act requires a court order before evicting a servicemember or their dependents, regardless of state procedure. If the servicemember can’t appear, the judge must appoint someone to represent their interests and can delay the case by up to 90 days.13U.S. Department of Justice. Financial and Housing Rights Skipping those federal requirements can expose you to serious consequences even if you followed every California step correctly.
