California Security Deposit Rules 2026: Limits & Deadlines

TL;DR: Since July 1, 2024, California law (AB 12) caps most security deposits at one month's rent, whether the unit is furnished or not — a narrow exception lets small landlords who own two or fewer rental properties charge up to two months' rent. Landlords have 21 calendar days after move-out to return the deposit or send an itemized statement with receipts for any deductions over $125. Withholding a deposit in bad faith can cost a landlord up to twice the deposit amount in statutory damages, on top of returning the money owed.

A tenant moves out, and now the clock is running whether you're ready or not. California's deposit rules changed in a real way with AB 12, and getting the cap, the deadline, or the deductions wrong is one of the fastest ways an independent landlord ends up in small claims court.

Okoniq Property Hub logs your move-in and move-out inspections, deposit amounts, and deduction receipts in one place, so the 21-day statement writes itself instead of becoming a scramble.

How much can a California landlord charge for a security deposit?

Most landlords can charge no more than one month's rent as a security deposit, regardless of whether the unit is furnished. That's the rule under AB 12, effective July 1, 2024, and it replaced the old system that allowed up to two months for unfurnished units and three months for furnished ones.

There's one carve-out. A landlord who owns no more than two rental properties, totaling no more than four rental units, can still charge up to two months' rent — but only if the tenant is not an active-duty servicemember, and this applies to individual landlords, not entities like LLCs or corporations that own the property. If you're setting deposit terms in the lease, it's worth reviewing this alongside the rest of your lease clauses so the number in the contract actually matches what the law allows for your situation.

Charging more than the legal cap doesn't just risk a refund order — tenants who successfully challenge an overcharge can also recover damages, and courts have little patience for landlords who "didn't know" the law changed in 2024.

How many days does a California landlord have to return a security deposit?

You have 21 calendar days from the date the tenant moves out to either return the full deposit or send an itemized statement explaining any deductions, along with copies of receipts or invoices for work over $125. This 21-day window applies statewide under California Civil Code Section 1950.5, and it doesn't pause for weekends or holidays.

If repairs aren't finished within the 21 days, you can send a good-faith estimate of the cost and follow up with final receipts within 14 additional days. Skipping the paperwork entirely and just keeping the money is the single most common mistake that turns a routine move-out into a dispute — and it's also the mistake that costs the most, since a tenant only needs to show you didn't itemize to win in court.

What can a landlord legally deduct from a security deposit?

Landlords can deduct for unpaid rent, damage beyond normal wear and tear, cleaning to restore the unit to its move-in condition, and any costs the lease specifically allows, such as restoring altered fixtures. Normal wear and tear — faded paint, worn carpet in high-traffic areas, minor nail holes — is not deductible, and this is where most disputes land.

The clearest way to protect a deduction is photo and written documentation from both the move-in and move-out inspections. If you're weighing whether interest is owed on top of the principal, check the separate rules on security deposit interest — California doesn't require it statewide, but several cities do.

| Deductible | Not Deductible | |---|---| | Unpaid rent or late fees specified in the lease | Faded paint or minor scuffs from normal living | | Carpet stains from pet damage | Worn carpet nap from years of foot traffic | | Broken window or damaged appliance | Small nail holes from hanging pictures | | Excessive cleaning beyond normal use | Light dust or minor scuff marks |

What happens if a landlord violates California's deposit rules?

A landlord who withholds a deposit in bad faith can be ordered to pay up to twice the deposit amount in statutory damages, in addition to returning what's owed. "Bad faith" generally means the landlord knew or should have known the deductions weren't legitimate — for example, charging for a full repaint on a unit that was only lived in for eight months, or simply ignoring the 21-day deadline without explanation.

Tenants can and do sue in small claims court for these disputes, and California's small claims limit ($12,500 for individuals as of 2024) covers the vast majority of deposit cases without a lawyer involved. If a deposit dispute escalates alongside a move-out that also involves an eviction, keeping your paperwork tight matters even more — see the basics on writing an eviction notice for how documentation habits carry over between the two processes.

How should landlords document deposits to avoid disputes?

Documentation is the difference between a deposit dispute you win and one you lose, so treat the move-in and move-out inspections as non-negotiable steps. Take dated, timestamped photos at both ends of the tenancy, use a written checklist the tenant signs at move-in, and keep every repair receipt tied to a specific unit and date.

Many independent landlords track this manually in spreadsheets and folders until a dispute forces them to reconstruct a timeline under pressure. Pairing your process with property management software built for independent landlords means the inspection photos, deposit ledger, and 21-day countdown are already organized before a tenant even asks for their money back. It's also worth making sure your screening and lease-signing process stays compliant from the start — a quick check of what landlords can't ask under fair housing law closes off a different but related source of legal risk.

FAQ

Does California require landlords to pay interest on security deposits?

No, California doesn't require interest on security deposits at the state level, but several cities, including San Francisco, Los Angeles, and Berkeley, have local ordinances requiring annual interest payments to tenants.

Can a California landlord charge a pet deposit on top of the security deposit?

No. Since AB 12 took effect in July 2024, any pet deposit counts toward the same one-month cap as the rest of the security deposit — landlords can't stack a separate pet fee on top of it.

What happens if a tenant disputes the itemized deduction statement?

The tenant can request further documentation or take the matter to small claims court, where California's limit for individuals is $12,500 as of 2024, and the burden is on the landlord to prove the deductions were legitimate and beyond normal wear and tear.

Is the security deposit cap different for month-to-month tenants?

No, the one-month cap under AB 12 applies the same way to month-to-month tenancies as it does to fixed-term leases, with the same small-landlord exception for those who own two or fewer rental properties.

Can a landlord keep the deposit if the tenant breaks the lease early?

Only for actual unpaid rent owed and legitimate damages tied to the early termination, such as re-renting costs specified in the lease — the landlord still can't keep the deposit simply as a penalty for breaking the lease.
