How to Write a 30-Day Notice to Landlord in California

To end a month-to-month tenancy in California, deliver your landlord a signed, written 30-day notice to vacate at least 30 calendar days before you plan to move out, and pay rent through the full notice period. Civil Code 1946.1 sets that 30-day rule for tenants, and it applies regardless of how long you’ve lived in the unit or whether your rental agreement is written or oral.¹ The notice can be given on any calendar day, and getting the details right matters, because a flawed notice can leave you owing extra rent or waiting longer for your deposit.

When 30 Days Is the Right Notice

The 30-day timeline is for month-to-month tenancies. If you pay rent monthly with no fixed end date on your agreement, you’re month-to-month, and 30 days’ written notice is all the state requires from you.² Your notice period stays 30 days whether you’ve been there three months or ten years. Landlords face longer timelines in some cases (60 days once a tenant has been in place 12 months or more), but that rule only affects the landlord’s obligation to you, not yours to the landlord.³

Fixed-term leases work differently. If you signed a lease with a specific end date, a 30-day notice does not let you walk away early. You remain liable for rent until the landlord finds a replacement tenant, though the landlord must make a reasonable effort to re-rent, and any rent from a new tenant offsets what you owe. One exception: if your fixed-term lease has already expired and you kept paying rent without signing a new agreement, the tenancy automatically converted to month-to-month, and the standard 30-day rule now applies.¹

What to Put in the Notice

California doesn’t require a specific form, but the document needs to be clear enough that nobody can dispute what you intended. Include:

The date you’re writing and delivering the notice. This is what starts the 30-day clock.
The full rental address, including apartment or unit number.
The specific date you intend to vacate, at least 30 days out from delivery.
Signatures from every adult tenant on the lease. The statute doesn’t strictly require all signatures, but a notice signed by only one co-tenant can raise questions about whether the whole tenancy is ending.
A forwarding address for your security deposit. Providing it up front removes one common excuse for a delayed refund.

Address the notice to the person your lease identifies for receiving legal notices. California landlords are required to disclose the name, phone number, and street address of the person authorized to manage the property and accept notices for the owner.⁴ If ownership has changed since you moved in, the most recent notice of ownership change should have the updated contact information.

How to Deliver It

The statute requires “written notice” but doesn’t dictate a delivery method for a tenant ending a month-to-month tenancy. The method you choose determines how easily you can prove the landlord received it, and proof matters if a dispute develops later.

The safest approach is to hand the notice directly to the landlord or property manager and ask them to sign and date a copy acknowledging receipt. If that isn’t practical, use certified mail with return receipt requested. The signed receipt card is your proof of delivery, and you’ll have the exact date it arrived. A private carrier like FedEx or UPS with tracking and delivery confirmation works too.

Email and text are risky unless your lease specifically authorizes electronic notice. Even if all your prior communication has been by email, an electronic termination notice may not hold up if the landlord disputes receiving it. Deliver a paper copy by a method that creates a paper trail, then follow up with an email as a courtesy. Keep copies of everything: the notice itself, any mailing receipts, and any signed acknowledgment.

The 30-day countdown begins on the day the notice is delivered, not the day you wrote it. If you mail it, the clock starts on arrival, so build in a few extra days for transit.

Rent During the 30 Days

You can give notice on any day of the month, and your tenancy ends exactly 30 days later. Rent gets prorated to match. Deliver notice on September 10 and your tenancy runs through October 10, so you owe 10 days of October rent on top of whatever remains for September.⁵ Watch the calendar: months have different lengths, so notice delivered on the 10th of a 31-day month ends the tenancy on the 9th of the next month, not the 10th.

Here’s the part most tenants miss. You owe rent for the full 30-day notice period whether you’re still in the unit or not. Moving out on day 15 does not cut your obligation in half. The only exception is if the landlord re-rents the unit to a new tenant before your 30 days expire and that new tenant starts paying. The landlord can’t collect rent from both of you for the same days.⁵

Giving fewer than 30 days’ notice doesn’t shorten what you owe. It just means the landlord can pursue you for the difference between the shorter notice and a full 30 days.

If You Stay Past the End Date

A tenant who remains after the 30-day notice expires becomes a holdover tenant, and the landlord can file an unlawful detainer action, California’s fast-track eviction lawsuit.⁶ You’ll typically have five days to respond after being served, and the case moves faster than a regular civil suit. Beyond the eviction itself, the landlord can seek damages for the days you overstayed, and an unlawful detainer judgment on your record makes it much harder to rent in the future.

If you need more time, ask the landlord for a written extension before your notice expires. The landlord cannot change your locks, shut off utilities, or remove your belongings without a court order.⁶

Move-Out Inspection and Deposit Return

After you give notice, the landlord must tell you in writing that you have the right to request a pre-move-out inspection. That inspection happens no earlier than two weeks before your termination date, and its purpose is to flag anything the landlord plans to deduct from your deposit so you can fix it yourself before you leave.⁷ If you request it, the landlord must give at least 48 hours’ written notice of the scheduled time, and you have the right to be present.

After the walkthrough, the landlord provides an itemized list of proposed deductions, and you have the remaining time before move-out to handle repairs or cleaning yourself, which almost always costs less than what the landlord would charge.

Once you’ve vacated and returned the keys, the landlord has 21 calendar days to either refund your full deposit or send an itemized statement of every deduction with receipts or invoices for the work performed.⁷ If a contractor did the work, the statement must include that contractor’s name, address, phone number, and a copy of the bill. If the landlord or an employee did the work, the statement must describe what was done and list the time spent and hourly rate. Landlords who withhold deposit funds in bad faith face statutory damages of up to twice the deposit amount, and small claims court is the standard remedy if you don’t receive the deposit or statement within 21 days.

If You’re Active-Duty Military

Federal law gives servicemembers a separate right to end a residential lease early without penalty under the Servicemembers Civil Relief Act. It applies when you receive permanent change of station orders, deployment orders for 90 days or more, or orders to enter active duty.⁸

To use it, deliver written notice of termination together with a copy of your orders. You can hand deliver, use a private carrier, send certified mail with return receipt requested, or deliver electronically. For a lease with monthly rent, termination takes effect 30 days after the next rent payment is due following delivery.⁸ If rent is due on the first and you deliver notice on March 15, the lease ends on May 1, which is 30 days after the April 1 payment date. The SCRA overrides any conflicting lease provision, including early termination fees. If your landlord tries to charge a penalty for a military-related termination, contact your installation’s legal assistance office before paying.
