Unlawful detainer california is the legal name for an eviction lawsuit, and Code of Civil Procedure section 1161 lists the reasons a landlord can file one. If your notice cites this section, your key number is three days, not counting Saturdays, Sundays, or court holidays, before an unlawful detainer california case can start.
What Unlawful Detainer California Actually Says
Section 1161 is a list of five situations. Each one lets a landlord ask a court to remove a tenant. The list is not a license to evict. It only tells you what the landlord has to prove, and which notice has to come first.
The most common ground is unpaid rent. The unlawful detainer california rule for rent is strict. The notice must be in writing. It must state the amount due. It must give the name, phone number, and address of the person you pay. If you can pay in person, it must also list the usual days and hours that person is available.
The landlord can also give you a bank account number instead. However, the bank has to be within five miles of your rental. If an electronic payment method was already set up, the notice can point to that. Here is the whole section at a glance:
| Provision | Exact rule | Section |
|---|---|---|
| Staying after the lease ends | Staying without the landlord’s permission. A tenancy at will must first be ended by notice under the Civil Code. | CCP 1161(1) |
| Unpaid rent notice | 3 days in writing, not counting Saturdays, Sundays, and judicial holidays | CCP 1161(2) |
| Deadline to serve a rent notice | Within 1 year after the rent became due | CCP 1161(2) |
| Bank payment option | The bank must be within 5 miles of the rental | CCP 1161(2) |
| Other lease violations | 3 days to fix the problem or move out. Weekends and judicial holidays don’t count. | CCP 1161(3) |
| Nuisance, waste, illegal use, or unapproved subletting | A 3-day notice to quit, with no chance to fix the problem | CCP 1161(4) |
| You gave notice to move out | You gave written notice under Civil Code 1946, or the landlord accepted your written offer to leave, and then you didn’t leave | CCP 1161(5) |
| Fees for notices | The landlord can’t charge you a fee for serving, posting, or delivering a notice | CCP 1161(6) |
| Current version in effect since | February 1, 2025 (SB 611, Stats. 2024, Ch. 287) | CCP 1161(8) |

Who Unlawful Detainer California Covers (and Who It Does Not)
Unlawful detainer california law reaches almost every renter. Section 1161 says “tenant” includes any person who rents real property. That covers apartments, houses, rooms, and mobile spaces you rent. It also covers subtenants. If a subtenant actually lives in the unit, the notice must be served on them too.
There is one exception. The section does not treat people as “tenants” if their stay is described in Civil Code section 1940(b). That subsection mostly covers short, hotel-style stays. If you’re not sure whether it applies to you, check with a legal-aid office.
Farm leases have their own rule. Sometimes an agricultural tenant stays more than 60 days after the lease ends, and the landlord never demanded the property back. In that case, the tenant is treated as holding over for another full year. Also, many California cities have their own rent and just-cause eviction rules. As a result, an unlawful detainer california case may need more than a valid 1161 notice. Check your city’s rent board or housing department.
What Your Landlord Must Do Under This Law
Your landlord can’t skip the notice step. For unpaid rent and most lease violations, they must serve a written three-day notice first. The notice must include every required detail. For example, a rent notice that leaves out the payee’s phone number is missing something the statute requires.
The landlord also can’t charge you a fee just for serving, posting, or delivering the notice. That rule comes from section 1161(6). Finally, a rent notice must be served within one year after the rent became due. An older rent debt can’t be the basis of a three-day rent notice under section 1161(2).
Mailing rent has a helpful rule too. Sometimes the address in the notice doesn’t allow personal delivery. If you mail your rent to that name and address, it counts as received on the date you mailed it. However, you need proof of mailing. Keep your receipt.
What You Can Do When It Is Broken
First, read the notice line by line. Compare it to the table above. Is the amount right? Is the payee’s name, phone number, and address there? Does it count the three days correctly? A notice with missing or wrong details may be a defense in an unlawful detainer california case.
Second, act inside the window if you can. Under section 1161(3), you can save your lease from forfeiture within the three days. You do that by fixing the violation or paying the rent owed. Get a receipt or other proof. However, some grounds, like nuisance or illegal use, don’t come with a chance to fix things.

Third, if you’re served with court papers, don’t ignore them. Unlawful detainer california cases move faster than most lawsuits. Your county’s superior court self-help center can give you the response forms. In most cases, it’s smart to contact a local legal-aid office or a tenant attorney right away. If you were charged a fee for a notice, tell them. Many tenants can raise these problems as defenses.
Frequently Asked Questions
Does a three-day notice mean I have to move out in three days?
No. A notice alone does not end your tenancy. In an unlawful detainer california case, the landlord still has to file in court and win. The three days are your window to pay or fix the problem first.
Can my landlord add a “notice fee” to what I owe?
No. Section 1161(6) bans fees for serving, posting, or delivering a notice. If one shows up on your ledger, write it down and bring it up with legal aid.
What if my rent notice asks for rent from more than a year ago?
Section 1161(2) says a rent notice must be served within one year after the rent became due. Older amounts may not support a rent notice in an unlawful detainer california case. Check the dates and ask a tenant attorney to review it.
Protect your stuff while you sort this out
A landlord’s insurance does not cover your belongings — renters insurance does, often for a few dollars a month. Compare options before your next move.
