Landlord & tenant
How do I send a security deposit demand letter?
Updated · By the SendMyLettersOnline team
Once your state's deadline for returning the deposit has passed, send your former landlord a written demand stating the amount, your move-out date, your forwarding address and a deadline to pay, by Certified Mail with a return receipt. In California, for example, the landlord must return the deposit or an itemized statement within 21 days after you move out, and a court can award up to twice the deposit for bad-faith retention (Civil Code 1950.5).
| Step | Why it matters |
|---|---|
| Find your state's return deadline | The demand is strongest once that deadline has passed |
| Give your forwarding address in writing | Many states tie the deadline or penalties to it |
| State the amount and a pay-by date | Gives the landlord a clear chance to settle |
| Attach move-out photos and the lease | Evidence that deductions aren't justified |
| Send certified with return receipt | Proves you made the demand before filing |
| File in small claims if unpaid | Bring the letter, receipt and return receipt |
California example
California Civil Code 1950.5 requires the landlord to return the deposit, minus allowed deductions with an itemized statement, within 21 days after the tenant moves out, and allows a court to award statutory damages of up to twice the deposit if the landlord kept it in bad faith. Other states set different deadlines and penalties, so check your own state's law before you cite numbers.
If the landlord doesn't pay
Small claims court is designed for disputes like this and you usually don't need a lawyer. Courts commonly ask whether you asked for payment before suing, and your certified letter and return receipt answer that. California's courts publish a small claims self-help guide.
