How does a Washington tenant dispute a deposit deduction?
Step 1: write a demand letter to the landlord (certified mail, return receipt) requesting the deducted amount, citing RCW 59.18.280 and any specific deductions disputed. Step 2: if the landlord does not respond within a reasonable time (typically 14-30 days), file a small-claims action in the county where the property is located. Filing fees range $30-$100. Step 3: at the hearing, present the move-in checklist, photos, lease, deposit receipt, and the landlord's itemized statement. Up to 2x the wrongfully withheld amount plus attorney fees under RCW 59.18.280(2). Many Washington tenants prevail simply because the landlord failed to itemize within the statutory deadline.

This is an informational answer based on RCW 59.18.280 as of early 2026. It is not legal advice. Housing law changes year to year and local ordinances (especially in rent-controlled or rent-stabilized cities) can override or add to state law. For contested cases, consult a Washington-licensed attorney.
