A security deposit in California isn't your money. It's the tenant's money, and you're holding it in trust. That's not a philosophical position. It's how Civil Code Section 1950.5 has always worked. But between 2024 and 2026, three new laws rewrote the mechanics of how you collect it, how you justify keeping any of it, and how you return it.
A San Leandro landlord holds back $3,000 from a deposit. He has cleaning invoices. He has photos of the spotless unit after the cleaning crew left. He sends the itemized statement on day 23. The tenant files in small claims.
The judge asks a question the landlord isn't expecting: where's the photo of the damage before the cleaning? There isn't one. The judge rules bad faith and awards the tenant $9,000.
Three laws. One missing photo. One missed deadline. That's how it happens now.
Here's the full landscape: what you can hold, what you can deduct, the deadlines that will cost you if you miss them, and the penalty structure that makes a $3,000 mistake into a $9,000 judgment.
Why This Costs More Than It Used To
California doesn't just make you return the deposit if you get it wrong. If a judge finds you acted in bad faith (fabricated charges, billed for pre-existing damage, ignored the deadline), the court can order you to return the full deposit plus a penalty of up to twice that amount. That's not a fine you pay to the state. That's money the tenant walks out with.
Small claims limit: $12,500. No lawyer required for the tenant to file.
Three statutes converge to make that math possible. The rest of this article is how each of them works, and how to stay on the right side of all three.
The One-Month Cap (AB 12)
Since July 1, 2024, Assembly Bill 12 caps security deposits at one month's rent. Period. It doesn't matter if the unit is furnished or unfurnished. The old distinction between two months (unfurnished) and three months (furnished) is gone. Pet deposits are included in the cap. "Last month's rent" is included in the cap. You get one month total.
You can still charge up to two months' rent if all three conditions are met: you're a natural person (or an LLC where all members are natural persons), you own no more than two residential rental properties, and those properties collectively have four or fewer units. But this exception vanishes entirely if your tenant is an active-duty service member. One month max, no exceptions, even if you otherwise qualify. The California Attorney General's consumer alert on security deposits confirms these limits.
AB 12 only applies to deposits collected on or after July 1, 2024. If you lawfully collected a larger deposit before that date, you can keep holding it. But good luck competing for tenants when every other listing asks for one month.
Mandatory Photo Evidence (AB 2801)
AB 12 cut what you can hold. Assembly Bill 2801 raised the bar on what you need to prove before keeping any of it. We covered this in depth in our AB 2801 photo requirements article. The short version: three photo sets, no exceptions.
Document the unit's condition immediately before a new tenant moves in. Required for leases starting July 1, 2025 or later.
Photograph the unit exactly as the outgoing tenant left it. Before the cleaning crew, before any repairs, before anyone moves a single thing.
Same rooms, same angles, once the work is done. The before-and-after pair is what converts an invoice into a defensible deduction.
If you're deducting from the deposit and you don't have the "before" photo showing the damage, a judge will reject the deduction. An invoice proves you spent money. The photo proves the tenant caused the damage. Those are two different things, and only one of them wins in court.
These photo requirements apply to all move-outs on or after April 1, 2025, regardless of when the lease was signed.
The 21-Day Deadline That Can't Be Missed
This is the rule that generates the most small claims cases. The clock starts the moment your tenant moves out and returns the keys. You have exactly 21 calendar days to do one of three things:
Return the full deposit with no deductions, or return the remaining balance with a detailed itemized statement, receipts for any charges over $125, and the before-and-after photos required by AB 2801, or if repairs aren't finished, provide a good faith estimate of charges, and then send the final receipts within 14 days of the work being completed.
You forfeit the right to keep any portion of the deposit. Full stop. You must return 100% immediately. You can still sue the tenant separately for actual damages, but you lose the power to hold their money. If the tenant files first, you're defending a case where you already violated the statute.
The 14-Day Extension Trap
The good faith estimate option sounds like a safety valve. It's actually where a lot of landlords hang themselves. The statute gives you 14 days after repairs are completed to send the final receipts, not 14 days after you sent the estimate. If the work drags out and you forget to follow up with the final numbers, the tenant has a clean bad faith case against you. The estimate buys you time. It doesn't close the loop.
How to Actually Deliver the Statement
"Within 21 days" means in the tenant's hands, not in a mailbox. If you mail it on day 20 and it arrives on day 23, you're on the wrong side of the deadline. Email with delivery confirmation, certified mail with return receipt, or hand delivery with a signed acknowledgment. Those are the three formats that hold up. A regular email with no confirmation is proof you sent something. It isn't proof the tenant received it.
Starting January 1, 2026, if your tenant paid their deposit electronically (online portal, Zelle, bank transfer), you must offer the option to receive the refund electronically. You're required to offer the choice, not to force it. The tenant can still request a paper check. For multi-tenant leases, the default is a single payment to all tenants unless they agree in writing to a different arrangement. Get that agreement in writing or send one check.
What You Can Actually Deduct For (And What You Can't)
California law restricts deposit deductions to four categories. That's it. You can't label a deposit as "nonrefundable." You can't use it for anything outside these four buckets. The toggle below flips between what each category does and doesn't cover. The line between them is where most disputes are won and lost.
The "wear and tear" line is where most disputes happen. Sunlight fading curtains over five years? That's wear and tear, you pay. The tenant's dog shredding those same curtains? That's damage, the tenant pays. If you can't tell the difference, the judge definitely can.
Don't Skip the Pre-Move-Out Inspection
California law requires you to notify tenants in writing that they have the right to a pre-move-out inspection during their final two weeks. A lot of landlords skip this or treat it as a formality. That's a mistake.
If the tenant agrees to the inspection, you walk the unit together and provide a written list of visible damage. This becomes a "cure period." The tenant can fix the issues themselves before move-out and avoid deductions. If they choose not to fix them, your documented inspection becomes strong evidence that the damage existed, was identified, and the tenant was given fair notice.
If you refuse to offer the inspection, or leave obvious damage off your list, you may lose the ability to charge for those repairs later. It's a procedural trap that costs nothing to avoid.
Local Rules Stack On Top
Everything above is state law: the floor, not the ceiling. If you own property in unincorporated Alameda County, the county's just cause eviction ordinance adds its own layer. No-fault evictions require relocation assistance equal to two months' rent, and you can't fund that from the security deposit. That's a separate payment. Oakland, Berkeley, San Francisco, and other cities have their own deposit-related rules layered on top of the state requirements. Always check your local jurisdiction.
How We Handle Deposits at SLPM
At SLPM Property Management, deposit compliance isn't an afterthought, it's built into every turnover. Here's the workflow we follow for every single move-out:
- Offer the pre-move-out inspection in writing. Every tenant gets the required notice during their final two weeks. If they accept, we walk the unit, document issues, and give them the written list. If they decline, we document that too.
- Photograph the unit before touching anything. The maintenance team's first tool is a camera. Every room, every surface, every issue, date-stamped, before any cleaning or repairs begin.
- Complete repairs and photograph again. Same rooms, same angles, after the work is done. The before-and-after pair is the legal proof for every deduction.
- Deliver the itemized statement with photos within 21 days. No exceptions. The statement includes every deduction with an explanation, receipts for charges over $125, and the full photo set. We send via email with delivery confirmation.
- Return the balance promptly. If the tenant paid electronically, we offer electronic return per AB 414. The remaining deposit goes out before the deadline, not on the deadline.
