The return deadline is 21 days after the tenant vacates, with an itemized statement of deductions and copies of receipts/estimates as required. Interest: No statewide interest requirement; some cities impose local interest or other rules. Procedure, examples, and the opinions below hang off Cal. Civ. Code § 1950.5. Bad-faith retention can support statutory damages of up to twice the deposit amount in addition to the wrongfully withheld sum (§ 1950.5(l)).
