Return security deposit with itemized statement within 30 days of move-out. Washington law (RCW 59.18.280) requires, within 30 days after the rental agreement ends and the tenant moves out, handing over or mailing first class to the tenant's last known address a full and specific statement of the basis for keeping any of the deposit, with copies of the estimates or invoices supporting each damage charge, and any refund due, and missing the deadline makes the landlord liable for the full deposit, while an intentional refusal can cost up to twice the deposit plus the costs and attorney fees of a lawsuit the tenant wins.
