California Security Deposit Laws: Limits, 21-Day Return & Disputes

California security deposit law caps most residential deposits at one month’s rent, limits deductions to unpaid rent, damage beyond normal wear and tear, cleaning to the move-in standard, and restoration of personal property, and gives the landlord 21 calendar days after you move out to return the deposit or send an itemized statement. A landlord who keeps money in bad faith can be ordered to pay up to twice the deposit on top of what was wrongfully withheld.¹

How Much a Landlord Can Charge

Since July 1, 2024, the maximum security deposit is one month’s rent, whether the unit is furnished or unfurnished.¹ Pet deposits aren’t a separate bucket. Any money labeled a pet deposit counts toward the same one-month cap, so a landlord who already collected a full month’s rent cannot add more on top for a pet.

No deposit can be called “nonrefundable.” The statute prohibits any lease from characterizing a security deposit that way, and a provision that tries to is unenforceable.¹

The Small Landlord Exception

A narrow exception lets some small landlords charge up to two months’ rent. The landlord must be an individual, or an LLC where every member is an individual, and must own no more than two residential rental properties totaling no more than four units.² Property management companies and corporate landlords don’t qualify.

Service Members Are Always Capped at One Month

The small landlord exception does not apply to active service members. Their deposit stays at one month’s rent regardless of who owns the property.¹ Starting April 1, 2025, if a landlord charges a service member more than the standard or advertised deposit based on credit history, the landlord has to give a written explanation before the lease is signed and refund that extra amount after six months of on-time rent.³

What a Landlord Can Deduct

Deposits exist to cover specific costs, not to pad the landlord’s budget. A landlord may keep only amounts that are reasonably necessary for four purposes:¹

Unpaid rent owed at move-out.
Damage caused by the tenant or their guests, beyond normal wear and tear.
Cleaning needed to return the unit to the level of cleanliness it had when the tenancy began.
Restoring or replacing personal property the tenant was responsible for under the lease, again excluding ordinary wear.

The statute explicitly bars deductions for pre-existing conditions or the cumulative wear of ordinary use, whether that wear built up during your tenancy or an earlier one.¹ A carpet that was already worn when you moved in cannot be charged to you when you leave. The cleaning standard works the same way: if the unit wasn’t professionally cleaned at move-in, the landlord can’t bill you for a professional clean at move-out.

Normal Wear and Tear vs. Damage

Most deposit fights come down to this line. Normal wear and tear is the gradual deterioration that follows from simply living in a home: minor scuffs from furniture, paint faded by sunlight, carpet thinned in high-traffic areas, door handles loosened over the years. The landlord absorbs those costs.

Damage is something different. Large holes punched in walls, broken windows, deep gouges in hardwood, cigarette burns on counters, or carpet stained beyond cleaning by pet urine are all repair costs the landlord can legitimately deduct.

Document the Unit Before You Move In

Your ability to challenge unfair deductions later rests almost entirely on evidence you gather at the start. Before or on the day you take possession, photograph or video every room, including walls, floors, appliances, fixtures, windows, and any existing damage. Take close-ups of anything that isn’t pristine, and keep the timestamps intact in the file metadata.

A written move-in checklist that both you and the landlord sign creates an agreed record of condition. Without one, a later dispute over whether that stain was already there turns into your word against theirs. Do the same walkthrough on move-out so you have before-and-after documentation for every room.

The Pre-Move-Out Inspection

The landlord must notify you in writing that you can request a pre-move-out inspection, and must give that notice within a reasonable time after either party signals the tenancy is ending.¹ If you don’t get the notice, ask for it.

Once you request the inspection, the parties pick a mutually convenient time no earlier than two weeks before the tenancy ends. The landlord must give at least 48 hours’ written notice of the date and time; both of you can waive that in a signed writing.¹

At the inspection, the landlord walks through the unit and gives you an itemized list of anything that could support a deduction. You then have until move-out to fix those issues yourself, which almost always costs less than what the landlord would charge. After the inspection, the landlord cannot deduct for any visible issue that wasn’t on that list, unless the damage happened later or was concealed at the time.⁴

The 21-Day Return Rule

After you return the keys, the landlord has 21 calendar days to send either your full deposit or an itemized statement explaining every deduction along with whatever balance remains.¹ Give your landlord a written forwarding address before you leave. Without one, delays become easy to excuse.

The itemized statement has to list each deduction, the reason, and the exact dollar amount. Vague entries like “cleaning” or “repairs” don’t satisfy the statute.

When Deductions Reach $125

If deductions for repairs or cleaning total $125 or more, the landlord must attach supporting documentation. For outside contractors, that means copies of receipts or invoices. If the landlord or an employee did the work, the statement must describe what was done, how long it took, and the hourly rate charged, and that rate has to be reasonable.⁴

When Repairs Run Past 21 Days

Sometimes a repair genuinely can’t be finished in time. The landlord can then include a good-faith estimate with the itemized statement. Within 14 calendar days of completing the work or receiving the contractor’s documents, the landlord must send you the actual receipts and reconcile the estimate against the final cost.¹ If the vendor’s paperwork isn’t in the landlord’s hands within 21 days, the statement has to include the vendor’s name, address, and phone number so you can verify the work yourself.

If the Property Is Sold or Foreclosed

Your deposit survives a change in ownership. The outgoing landlord has to either transfer the remaining deposit to the new owner or return it directly to you.³ If the deposit is transferred, the previous landlord must notify you in writing with the new owner’s name, address, and phone number, plus any claims already made against the deposit.

If the handoff isn’t done properly, both the old and new owners are jointly and severally liable for returning your money, so you can pursue either or both. The new owner also can’t demand a replacement deposit without first returning the original.³ The same joint liability applies after a foreclosure.

Interest on Security Deposits

State law does not require landlords to pay interest on security deposits. Several rent-controlled cities, including San Francisco, Los Angeles, West Hollywood, and Berkeley, do require annual interest payments. If you rent in one of those jurisdictions, check your local ordinance for the current rate and payment schedule.

Getting Your Money Back When the Landlord Won’t Pay

If deductions look inflated or the 21-day deadline came and went, pull your evidence together: the lease, move-in and move-out photos or video, the itemized statement if you got one, and any written communication with the landlord.

Start With a Demand Letter

California courts require a written demand to the landlord before you can file a small claims case.⁵ Send it by certified mail with return receipt. Explain why the deductions are improper, state the amount you’re owed, cite the 21-day return requirement, and set a reasonable deadline for payment.

Small Claims Court

If the landlord doesn’t respond or refuses to pay, you can sue in small claims court. Individuals in California can file claims up to $12,500.⁶ Filing fees run $30 to $75 depending on the amount claimed.⁷ You don’t need a lawyer; attorneys aren’t allowed to represent parties in California small claims cases.

Bad Faith Penalties

A court that finds the landlord acted in bad faith can award statutory damages of up to twice the deposit, on top of the amount wrongfully withheld.¹ On a $2,000 deposit kept without justification, that’s $2,000 in actual damages plus up to $4,000 in statutory damages.

The landlord carries the burden of proving each deduction was reasonable. You don’t have to prove the charges were bogus; the landlord has to prove they were legitimate.¹ Missing the 21-day deadline, failing to supply receipts, and deducting for normal wear and tear can all support a bad faith finding.

The Evidence That Decides These Cases

Timestamped move-in and move-out photos are the strongest evidence you can bring. Side-by-side images of the same wall, floor, or appliance on both dates make it hard for a landlord to pin existing wear on you. Written witness statements help, and the signed move-in checklist can be decisive. Bring printed copies of everything; the judge won’t scroll through your phone.
