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

California security deposit laws cap most residential deposits at one month’s rent, limit deductions to unpaid rent, damage beyond normal wear and tear, cleaning, and restoring personal property, and require the landlord to return the balance with an itemized statement within 21 days of move-out. A landlord who acts in bad faith can be ordered to pay up to twice the deposit as a penalty on top of what was wrongfully withheld. The rules sit in Civil Code Section 1950.5, and the one-month cap has been in place since July 1, 2024.¹

How Much a Landlord Can Charge

The maximum security deposit is one month’s rent, whether the unit is furnished or unfurnished.¹ Before July 1, 2024, landlords could charge up to two months for unfurnished units and three months for furnished ones. Those higher limits are gone.

Small Landlord Exception

A narrow group of landlords can still collect up to two months’ rent. To qualify, the landlord must be an individual (or an LLC where every member is an individual) and own no more than two residential rental properties totaling four dwelling units or fewer.² If you rent from a property management company or a corporate owner, the exception does not apply.

Service Members

Active service members are always capped at one month’s rent, even when the small-landlord exception would otherwise allow more.¹ Starting April 1, 2025, if a landlord charges a service member more than the standard or advertised deposit because of credit history, the landlord must give a written explanation before the lease is signed, and the extra amount must be returned after six months of on-time rent payments.³

Pet Deposits and “Nonrefundable” Fees

A pet deposit is not a separate category. Any amount collected for a pet counts toward the same one-month cap. And no security deposit in California can be labeled nonrefundable; the statute prohibits any lease from characterizing a deposit that way, so a provision saying otherwise is unenforceable.¹

What a Landlord Can Deduct

Deductions must be “reasonably necessary” and can only cover four things:¹

Unpaid rent owed at the time you move out.
Damage beyond normal wear and tear caused by you or your guests.
Cleaning, but only to return the unit to the level of cleanliness it was in when you moved in.
Restoring or replacing personal property you were responsible for under the lease, excluding normal wear and tear.

The law expressly bars deductions for pre-existing conditions or for the cumulative wear from ordinary use, whether that wear built up during your tenancy or a previous one. If the carpet was already worn when you moved in, the landlord cannot charge you to replace it when you leave.

Normal Wear and Tear vs. Damage

Normal wear and tear is the gradual deterioration that comes from living in a home: minor wall scuffs from furniture, faded paint from sunlight, carpet worn in high-traffic paths, loosened door handles. Those costs sit with the landlord. Damage is different: large holes in walls, broken windows, deep floor gouges, cigarette burns on countertops, carpet ruined by pet urine. Those costs can come out of the deposit. The cleaning standard follows the same baseline: if the unit was not professionally cleaned when you moved in, the landlord cannot bill you for a professional cleaning on the way out.¹

Move-In Documentation and the Pre-Move-Out Inspection

Your leverage in any later dispute depends on evidence collected before you ever unpack. Photograph or video every room, appliance, and fixture on the day you take possession, with close-ups of anything that isn’t pristine, and keep the file metadata intact so timestamps are visible. A written move-in checklist signed by both parties turns a later argument about a stain into a resolved question.

California also requires the landlord to notify you in writing that you can request a pre-move-out inspection.¹ The notice has to come within a reasonable time after either party gives notice of ending the tenancy. If it doesn’t come, ask for it. The landlord’s duties under this section are not discharged unless you affirmatively decline the inspection.

Once you request it, the inspection is scheduled no earlier than two weeks before the end of the tenancy, with at least 48 hours’ written notice of the date and time. That 48-hour requirement can only be waived by a written waiver signed by both parties.¹

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

The 21-Day Return Rule

After you move out and return the keys, the landlord has 21 calendar days to either return the full deposit or send an itemized statement of deductions with any remaining balance.¹ Give the landlord a forwarding address in writing before you leave. Without one, they have a built-in excuse for delay.

The itemized statement must list each deduction, the reason, and the exact dollar amount. Entries like “cleaning” or “repairs” with no specifics don’t satisfy the law.

Receipts and Documentation

When total deductions for repairs or cleaning reach $125 or more, the landlord must attach supporting documentation. Work done by an outside contractor requires copies of the receipts or invoices. Work done by the landlord or an employee has to be described in the statement, along with the time spent and a reasonable hourly rate.⁴

When Repairs Aren’t Finished in 21 Days

If a repair genuinely can’t be completed in time, the landlord can include a good-faith cost estimate with the itemized statement. Within 14 calendar days of finishing the repair or receiving the contractor’s paperwork, the landlord must send you the actual receipts and adjust the accounting if the final cost differs from the estimate.¹ If the vendor’s documents are not in the landlord’s possession within 21 days, the statement must list the vendor’s name, address, and phone number so you can verify the work.

If the Property Is Sold or Foreclosed

Your deposit survives a change of ownership. The outgoing landlord must either transfer the remaining deposit to the new owner or return it to you. If it’s transferred, the previous landlord must notify you in writing with the new owner’s name, address, and phone number, along with any claims already made against the deposit. If that transfer never happens properly, both the old and new owners are jointly and severally liable for the money, so you can pursue either one or both. A new owner also cannot demand a replacement deposit without first returning the original.³ The same joint-liability rule applies after a foreclosure.

Interest on Deposits

State law does not require landlords to pay interest on security deposits. Several California cities with rent control, including San Francisco, Los Angeles, West Hollywood, and Berkeley, do require annual interest payments. Rates and payment schedules vary, so check the local ordinance if you rent in one of those jurisdictions.

Getting Your Money Back When the Landlord Won’t Pay

If deductions look inflated or the 21-day deadline has passed with nothing from the landlord, pull together your lease, move-in and move-out photos, the itemized statement (if any), and every written exchange with the landlord.

Send a Demand Letter

Before filing a small claims case, California requires a written demand to the landlord.⁵ Send it by certified mail with a return receipt. Explain why the deductions are improper, state the amount owed, cite the 21-day rule, and set a reasonable deadline.

Small Claims Court

If the demand is ignored, you can sue in small claims court. Individuals can file for up to $12,500.⁶ Filing fees run from $30 to $75 depending on the amount claimed.⁷ Attorneys are not allowed to represent parties in California small claims cases, so you don’t need one.

Bad-Faith Damages

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

The burden is on the landlord to prove that deductions were reasonable, not on you to prove they weren’t.¹ Missing the 21-day deadline, failing to attach required receipts, or charging for normal wear and tear can all support a bad-faith finding. Timestamped move-in and move-out photos are the strongest evidence in these cases; side-by-side comparisons of the same wall, floor, or appliance make it hard for a landlord to claim you caused damage that was already there. Bring printed copies of everything to the hearing.
