Security deposit return deadlines

Engraving of a tear-off desk calendar with a blank leaf, a stamped envelope and a rubber date stamp on its ink pad — Calendar, envelope, date stamp: the window is short, and it starts before most landlords think it does.

21 days

In most statutes it runs from the day the tenant vacates — not from the day you finish the repairs or receive the invoice.

Deposit deadlines are the sharpest edge in landlord-tenant law: short, mechanical, and penalised on a multiple. The deductions can be perfect and still worthless if the statement goes out a day late.

What starts the clock

Statutes pick one of three triggers: the day the tenant vacates, the day the tenancy legally terminates, or the day you receive a forwarding address. They are frequently different dates. California uses the first — 21 calendar days after the tenant has vacated the premises (Civ. Code § 1950.5, checked 2026-10-18).

Repairs do not pause the clock. If the contractor is booked out three weeks, you send the statement with a written estimate inside the window and reconcile afterwards where the statute allows it.

What has to be in the envelope

An itemised statement, line by line, in plain words.
Receipts or written estimates for the lines you charged.
The balance owed, as a cheque or an electronic payment the tenant can actually access.
Any interest owed on the deposit — see the interest calculator.

Send it to the forwarding address if you have one, and to the last known address if you do not. Keep proof of posting; a statement you cannot prove you sent is a statement you did not send.

What missing it costs

Failure	Common consequence
Statement late	Deductions forfeited; full deposit returnable
Statement never sent	Statutory damages, often a multiple of the deposit (up to twice it in California, for bad faith)
Bad faith retention	Damages plus the tenant's legal costs
No itemisation	Treated as no statement at all

Exact multiples are state-specific. The shape — forfeiture first, multiples second, costs third — is near-universal.

Running it as a system, not a scramble

01Diary the deadline the day notice is served, not the day the keys come back.
02Book the move-out inspection for the handover day itself.
03Get estimates the same week — an estimate is enough for the statement.
04Build the statement in the deduction calculator and post it with a week to spare.
