California security deposit laws: Limits, deadlines and Itemized returns

Missing that deadline is the single most common way California landlords lose money they were otherwise entitled to keep.

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

One month's rent (§ 1950.5(c)). The limit counts the total of everything held as security, whatever it is called in the lease — cleaning deposit, pet deposit, key deposit, damage deposit. Renaming a charge does not move it outside the cap. Rent paid for the first month is not part of the deposit; rent collected for the last month usually is.

There are narrow exceptions: a small landlord owning no more than two rental properties with four units or fewer in total may collect up to two months' rent, unless the tenant is a service member (§ 1950.5(c)(2)).

How long does a California landlord have to return a security deposit?

21 days from the end of the tenancy (§ 1950.5(g)(1)). The clock runs from when the tenant gives up possession, not from when the lease was scheduled to end and not from when the landlord finishes repairs. Within that window the landlord must deliver either the full deposit, or the remaining balance plus an itemized statement accounting for every dollar withheld.

What must be on a California itemized deposit statement?

The statement must identify each deduction and the amount, and — above a threshold of $125 — attach receipts, invoices or a good-faith estimate of the work (§ 1950.5(g)(2)). "Cleaning: $400" on its own is not an itemization. Where the landlord did the work personally, the statement must describe the work and state the hourly rate and time spent.

What can a California landlord legally deduct?

The line between damage and wear and tear is the most-litigated part of this statute. The practical defence is documentation: a signed move-in inspection checklist with dated photographs, held by both parties. Without one, the landlord is arguing from memory.

Does a California landlord have to pay interest on a security deposit?

Not under state law (§ 1950.5). This is the rule most often stated incorrectly online, because several California cities impose their own interest requirements that state law does not. If the property sits in a city with a rent-control or deposit ordinance, the local rule applies on top of the state one.

Do California cities have their own security deposit rules?

Yes — and they override the state floor where they are stricter. Los Angeles, San Francisco, Berkeley, Oakland, Santa Monica and West Hollywood all run local ordinances touching deposits, interest, or both. State law is the minimum, not the whole answer, and a lease drafted only to the state standard can still be non-compliant at the city level.

What happens if a landlord misses the return deadline?

Missing the 21-day deadline generally forfeits the right to withhold anything, even for genuine damage, and exposes the landlord to statutory penalties of up to twice the amount of the deposit where the retention was in bad faith (§ 1950.5(l)). A deposit dispute that would have been a $600 argument becomes a multiple-damages claim.

Is there a pre-move-out inspection requirement in California?

Yes — the landlord must tell the tenant in writing that they can request one (§ 1950.5(f)). Where it applies, the tenant has the right to be present, and to be told in writing what the landlord intends to deduct — which gives them a chance to fix it themselves. Landlords who skip this step lose the ability to claim for anything the tenant could have remedied.

How your California lease should handle the deposit

Four things belong in the document itself, not in a side conversation:

1. The amount held, stated as a figure, with every component named so nothing looks like a hidden fee later.
2. What it covers — unpaid rent, damage beyond wear and tear, cleaning to move-in condition.
3. The return process — the {{CA_RETURN_DAYS}}-day window, the itemized statement, and where the tenant should send a forwarding address.
4. A move-in condition record, signed by both parties, attached to the lease as an addendum.

A lease that carries all four turns a deposit dispute into a document-reading exercise. A lease that carries none turns it into a credibility contest.
