Washington security deposit law: the 30-day deadline, penalties, and how to get your money back
Under RCW 59.18.280, your landlord has 30 days after you move out to return your security deposit or send an itemized statement of deductions. The landlord becomes liable for the full deposit, cannot withhold any portion, and (absent circumstances beyond their control) cannot charge for damages, report the debt to screening agencies, or send it to collections.

The 30-day deadline and itemization rules
The statement must be 'full and specific' — each basis for withholding listed with its cost — and postmarked within the 30-day window; a statement without supporting cost documentation is noncompliant.
Since July 2023 the landlord must attach copies of estimates, invoices, bills, or receipts for repair/cleaning costs (and a time-and-rate statement for their own labor); deductions are barred for ordinary wear, undocumented move-in-checklist items, or costs exceeding replacement value (RCW 59.18.280).
Penalties for wrongfully keeping your deposit
For intentional refusal to provide the statement or refund, the court may award up to two times the full deposit (RCW 59.18.280(2)); the prevailing party also recovers court costs and reasonable attorney's fees.
No deposit may be collected without a written rental agreement and a signed move-in condition checklist (RCW 59.18.260) — otherwise the landlord owes the deposit back plus fees. Deposits must be held in a disclosed Washington trust account (RCW 59.18.270). Claims must be filed within 3 years.
Taking your landlord to small claims court (district court)
If a demand letter does not resolve the dispute, Washington lets you sue in Small Claims Court (district court) for up to $10,000. Filing fees typically run $35–$50, lawyers are optional, and deposit cases are among the most common — and most tenant-friendly — small claims matters.
