How do I dispute a security deposit return in Washington?

Washington's Residential Landlord-Tenant Act (RCW Ch. 59.18) governs deposits in RCW 59.18.280, recently amended by 2024 legislation tightening timelines.

1. Move-In Checklist Required

The landlord must furnish a written move-in checklist describing the condition of the premises at the start of tenancy, signed by both parties. Failure to do so means the landlord cannot collect a deposit at all (RCW 59.18.260).

2. 21-Day (formerly 30) Return Rule

After 2024 reforms (HB 2114), the landlord must return the deposit and itemized statement within 21 days after the tenant vacates and provides a forwarding address. (Older leases still under 30-day rule.)

3. Allowed vs. Prohibited Deductions

Permitted: unpaid rent, charges for damage beyond ordinary wear and tear. Prohibited: ordinary wear and tear, routine cleaning, repainting after long tenancies. Cleaning may be deducted only if necessary to return the unit to the same level of cleanliness as in the move-in checklist.

4. Penalty for Failure to Comply

A landlord who fails to provide the itemization within the deadline forfeits all rights to retain any portion. If the failure is in bad faith, the tenant may recover up to 2x the deposit plus costs and reasonable attorney's fees (RCW 59.18.280(2)).

5. Demand Letter & Small Claims

Send a written demand by certified mail. Then file in Washington district court small claims (up to $10,000). The statute of limitations is 6 years for written contracts (RCW 4.16.040).
