California Security Deposit Law: A Renter's Guide
California gives landlords 21 calendar days to return a security deposit or send an itemized statement of deductions. Here's how the law works and how to draft a demand letter that holds your landlord to it.
The 21-day rule
Within 21 calendar days of you moving out, the landlord must either return the full deposit or send a written, itemized statement explaining any deductions, along with the remaining balance.
Receipts and invoices
When deductions exceed the statutory threshold, California law generally entitles the tenant to copies of receipts or invoices for the work claimed. A demand letter is the right place to request them.
Bad-faith withholding
California courts can award statutory damages in addition to the deposit itself if a landlord withholds in bad faith. Your demand letter should quote the 21-day rule and request payment by a clear deadline.
