California Security Deposit Return Deadline: The 21-Day Rule
After a tenant moves out, a California landlord has 21 calendar days to either return the full deposit or send an itemized statement of deductions with the balance. The clock starts the day the tenant vacates, and missing it is the easiest way for a small landlord to turn a routine move-out into a dispute (Civil Code §1950.5(h)(1)).
What you must send within 21 days
- The full deposit, or
- An itemized statement of every deduction, plus whatever is left of the deposit.
Permitted deductions are limited to unpaid rent, cleaning needed to return the unit to its move-in condition, and repair of damage beyond ordinary wear and tear.
What the itemized statement needs
- Each deduction listed separately, with the amount.
- Copies of the bills, invoices or receipts for repair and cleaning charges. If you or your employee did the work, describe it and state the time spent and a reasonable hourly rate (Civil Code §1950.5(h)(2)).
- The dated photos of the unit taken before and after the repairs or cleaning (§1950.5(h)(2)(D); see our photo documentation article).
You can skip those documents if your repair and cleaning deductions together do not exceed $125, or if the tenant signed a valid waiver (§1950.5(h)(4)).
When you can't finish the work in 21 days
If a repair can't reasonably be completed within 21 days, or the contractor's paperwork hasn't reached you yet, you may deduct a good-faith estimate and send it with the statement. You then must complete the paperwork (actual bills and photos) within 14 calendar days of finishing the repair or receiving the documents (§1950.5(h)(3)). An honest estimate is fine; padding it is not.
What a missed deadline can cost
Retaining a deposit in bad faith can expose a landlord to statutory damages of up to twice the deposit, on top of the tenant's actual damages (Civil Code §1950.5(m)). Bad faith is a finding a judge makes, but a deadline that passed with nothing sent, and no explanation, is the kind of fact courts point to.
A simple way to never miss it
- On the day the tenant returns the keys, write the 21st day on your calendar.
- Take the move-out photos before any cleaning or repairs.
- Collect receipts as work finishes, and send the statement by day 18, not day 21.
- Keep proof of when and how you sent it.
