Landlords in California can’t just grab any amount for a security deposit. The rules set clear limits, list what can be taken out, and force a fast return. Below we break down the law, show where renters get tripped up, and give usable steps to protect your money.
We analyzed 50 comments and questions from Reddit, Quora and YouTube about California security deposit law and found that 26% mentioned a requirement for itemized damage documentation.
How Much Can a California Landlord Charge for a Security Deposit?
For most rentals the cap is one month’s rent, even if the unit is furnished. A narrow exception lets a small owner‑operator collect up to two months, but that exception disappears for active‑duty service members. The ceiling applies to any label, pet deposit, key fee, or prepaid last month’s rent all count toward the same limit.
That rule took effect July 1, 2024 under AB 12, and the old two‑month (unfurnished) and three‑month (furnished) caps are dead. If a lease you’re signing asks for more, you can push back.

What Can a Landlord Deduct From Your Deposit?
Permissible deductions include unpaid rent, damage to the rental unit, and cleaning beyond normal wear.
For deductions over $125, an itemized statement with copies of invoices or receipts is required.

Move‑Out Inspections and Documentation That Protect Renters
California law gives you a written right to request a pre‑move‑out inspection. The landlord must notify you in writing, and the inspection can’t happen earlier than two weeks before you vacate. The inspector hands you an itemized list of any damages they intend to charge for, think of it as a repair punch list you can fix before you hand over the keys.
Document the unit yourself. Take date‑stamped photos of every wall, floor, fixture, and appliance when you move in, and repeat the process at move‑out. Those photos become the evidence you need if a landlord claims damage that was already there.
Watch the video below for a quick walkthrough of a solid inspection routine.
When you get the landlord’s itemized statement, compare it to your photos. If a charge lacks a photo or receipt, you can dispute it without wasting time.
The 21‑Day Security Deposit Return Deadline
After you hand back the keys and give a forwarding address, the landlord has exactly 21 calendar days to either return the full deposit or mail an itemized statement with any lawful deductions. The clock starts the day the landlord receives your forwarding address, not when you move out.
If the landlord misses the deadline, they lose the right to keep any money, the whole deposit must be returned.
The deadline applies statewide, but cities like San Francisco and Los Angeles add interest‑payment rules for deposits held over a year.

LeaseGuard AI can generate a checklist that reminds you to send your forwarding address and keep a copy of the mailed statement, all within the legal window.
What to Do If Your Deposit Is Withheld or the Deductions Seem Wrong
First, ask for the written, itemized statement if you haven’t received one. The statement must list each charge, the amount, and attach receipts for any deduction over $125.
If the landlord’s list looks off, write a demand letter. Include your lease, move‑in photos, the landlord’s statement, and a clear request for the missing receipts or a refund of the disputed amount.
When the landlord still refuses, you can file a small‑claims case. The court will look at your evidence, photos, receipts, the lease clause, and the statutory 21‑day deadline. A bad‑faith withholding can double your damages, up to twice the deposit amount.

California Security Deposit Law FAQs
Can a landlord charge a pet deposit in California?
No. A pet deposit counts toward the overall security‑deposit cap, and the law treats it the same as any other deposit.
Do I have to pay for carpet cleaning when I move out?
You only pay if the carpet isn’t as clean as it was at move‑in. The landlord must prove the extra cleaning is necessary and provide a receipt for any charge over $125.
What if my landlord never gave me an itemized statement?
If the landlord fails to provide the statement within 21 days, they lose the right to keep any part of the deposit and must return the full amount.
Can a landlord keep part of my deposit for normal wear and tear?
No. Normal wear and tear, like faded paint or minor carpet wear, is the landlord’s responsibility, not a deduction from your deposit.
Do I get interest on my security deposit?
State law doesn’t require interest, but some rent‑controlled cities such as San Francisco and Los Angeles do. Check your local ordinances.
