Security Deposits in LA: The 1-Month Cap, 21-Day Return & Getting Yours Back

Your security deposit is often the single largest sum you hand a landlord besides rent, and California law is unusually protective about how it can be held and returned. Since AB 12 took effect on July 1, 2024, the rules got even friendlier to renters. This guide walks through what a Los Angeles tenant needs to know: how much a landlord can legally collect, the strict 21-day return clock, what can and cannot be deducted, the new timestamped-photo requirements, deposit interest for LA city rent-stabilized units, and exactly how to fight back if your money does not come home.

This is educational information, not legal advice. Every figure below is tied to a primary California statute or an official Los Angeles agency, and we flag anything that changes year to year so you can confirm the current number yourself.

The 1-month cap: what AB 12 changed

Under California Civil Code §1950.5(c), as amended by AB 12 (effective July 1, 2024), a landlord may not demand or receive a security deposit greater than one month's rent, whether the unit is furnished or unfurnished. This is a sharp cut from the old law, which allowed up to two months (unfurnished) or three months (furnished). The "first month's rent paid in advance" does not count toward the deposit, so a typical move-in is now first month plus one month's deposit.

There is one narrow exception. A landlord who is a natural person (or an LLC where every member is a natural person) and who owns no more than two residential rental properties that together contain no more than four dwelling units may collect up to two months' rent as a deposit. Corporate landlords, REITs, and larger portfolios get no such exception, and even the small-landlord exception cannot push a service-member's deposit above one month. If a leasing office quotes you a "last month's rent" charge on top of a full deposit, add it up: the total of everything labeled deposit, last month, pet deposit, or key deposit is what the one-month cap measures against.

The 21-day itemized return rule

Civil Code §1950.5(g) gives the landlord a hard deadline: no later than 21 calendar days after you vacate, they must either return your full deposit or mail you an itemized statement listing each deduction, plus whatever balance is left over. Twenty-one days means twenty-one days, weekends and holidays included, counted from when you actually move out and hand back possession, not from the lease end date.

If any single deduction exceeds $125, the landlord must attach copies of receipts, invoices, or bills documenting the work. If their own employees did the work, the statement must describe the work, the time spent, and the hourly rate. When materials or repairs cannot be documented within 21 days (say a contractor is slow to invoice), the landlord may send a good-faith estimate and then has 14 additional days to provide the actual receipts.

Missing the 21-day window is not a technicality landlords can shrug off. A landlord who fails to return the deposit or provide the itemized statement in time can forfeit the right to keep any of it, and if a court finds the retention was in bad faith it may award you up to twice the deposit amount in statutory damages on top of the deposit itself.

What can and cannot be deducted

California limits deductions to four categories under §1950.5(b): (1) unpaid rent; (2) cleaning the unit to make it as clean as when you moved in; (3) repair of damage beyond normal wear and tear; and (4) restoring or replacing personal property (like keys or furniture) if your lease allows it. That is the entire list.

The dividing line that matters most is normal wear and tear versus damage. Landlords may deduct for genuine damage but not for the ordinary aging of a unit. Things a landlord generally cannot charge you for:

• Faded paint, minor scuffs, or nail holes from normal hanging of pictures after a multi-year tenancy
• Worn or lightly stained carpet that has simply reached the end of its useful life
• Routine "make-ready" costs the landlord incurs to re-rent, such as general repainting between tenants
• Loose grout, minor caulk wear, or small carpet wear near doorways

Things that can be deducted include large holes in walls, pet urine damage to flooring, broken fixtures or appliances caused by misuse, missing keys, and cleaning a unit left visibly dirtier than move-in condition. A landlord also cannot deduct for conditions that existed before you moved in, which is exactly why the photo rules below matter so much.

AB 2801: the new timestamped-photo rules

AB 2801 amended §1950.5 to require photographic evidence, phasing in over 2025 (these provisions were carried forward by AB 414, Stats. 2025, Ch. 340, effective January 1, 2026). The point is to stop landlords from charging for damage that was never yours.

• Move-out photos (since April 1, 2025): The landlord must take photographs of the unit within a reasonable time after you return possession but before making any repairs or cleaning.
• Move-in photos (tenancies starting on or after July 1, 2025): The landlord must take photographs of the unit immediately before, or at the start of, your tenancy.
• Documentation with the itemized statement: When a landlord deducts for repairs or cleaning, they must include the relevant photographs along with the itemized statement.

You do not have to wait for the landlord. Take your own timestamped, date-marked photos and a short walk-through video the day you move in and again the day you move out, and email them to yourself so there is a server timestamp. This is the cheapest insurance you will ever buy against a bogus deduction.

RSO deposit interest for LA city units

Here is a benefit many Los Angeles renters never claim. Under the City of Los Angeles Rent Stabilization Ordinance (RSO), landlords of covered rental units (generally buildings with two or more units built on or before October 1, 1978) must pay tenants annual interest on their security deposits. This is a City of Los Angeles rule that applies on top of the statewide deposit protections; it does not apply to units outside the city or to units the RSO does not cover.

The interest rate is set and published each year by the Los Angeles Housing Department (LAHD), and it changes annually, so do not rely on a number you saw in an old article. Check LAHD's current published deposit-interest rate before you calculate what you are owed. Interest is generally payable to the tenant once a year (or credited toward rent), and accrued interest that was never paid can be claimed when you move out. If you live in a rent-stabilized building and have never received a deposit-interest payment, that is money quietly owed to you.

Not certain whether your building falls under the city RSO, the LA County RSTPO (which covers only unincorporated areas), or neither? The correct jurisdiction determines your rights, so start with our guide to what the LA RSO covers and confirm the layer that applies to your address.

How to get your deposit back: the demand-letter path

If the 21 days pass with no deposit and no itemized statement, or the deductions are obviously padded, you have a clear escalation path.

• Step 1: Send a written demand letter. Politely state your move-out date, note that §1950.5(g) required return within 21 days, list the amount owed, and give a firm deadline (7 to 14 days). Attach your move-in and move-out photos. Send it by both email and certified mail so you have proof of delivery, and keep a copy.
• Step 2: Reference the bad-faith penalty. Mention that California law allows a court to award up to twice the deposit as a penalty for bad-faith retention. Many landlords settle once they see you know the statute.
• Step 3: File in small claims court. California small claims handles individual claims up to $12,500, and you do not need a lawyer (attorneys are generally not even allowed to represent parties in small claims hearings). The filing fee is modest and can be waived if you qualify. Bring your lease, the demand letter with proof of delivery, your photos, and the landlord's itemized statement if you got one.

Keep everything in writing, stay factual, and lean on your documentation. Between the 21-day rule, the receipt-and-photo requirements, and the double-damages penalty, the law gives a prepared tenant substantial leverage.

Frequently asked questions

Can my landlord charge a non-refundable cleaning fee?

No. California does not permit non-refundable deposits or fees of any kind for residential tenancies. Any amount labeled a "non-refundable cleaning fee" is still legally part of your refundable deposit and is subject to the one-month cap and the 21-day return rule.

Does the 21-day clock start when my lease ends or when I move out?

When you actually vacate and return possession, which can be earlier or later than the lease end date. Return your keys promptly and in a documented way (in person with a receipt, or by certified mail) so there is a clear record of when the 21 days began.

My landlord kept my whole deposit for repainting. Is that legal?

Usually not. Routine repainting to make a unit ready for the next tenant is generally considered normal wear and tear, not tenant damage, especially after a multi-year tenancy. Painting is only deductible when it repairs damage you caused beyond ordinary use, and the landlord must document it with receipts and photos.

What if my landlord never sent an itemized statement at all?

Then they have likely forfeited the right to keep any of your deposit. Send a demand letter citing the 21-day deadline in §1950.5(g), and if that fails, file in small claims, where you can ask for the full deposit plus up to twice its value if the retention was in bad faith.

I live in a rent-stabilized LA building. Am I owed deposit interest?

Likely yes. The city RSO requires landlords of covered units to pay annual interest on security deposits at the rate LAHD publishes each year. If you have never received it, calculate what is owed using LAHD's published rates for each year of your tenancy and request it in writing.
