Washington Security Deposit Law: 21 days Return Rule

Washington's Residential Landlord-Tenant Act (RCW 59.18.280) gives landlords 21 days after you move out to return your security deposit along with a written statement itemizing any deductions. If the landlord misses the deadline or acts in bad faith, RCW 59.18.280(3) allows you to recover up to twice the deposit amount plus attorney's fees.

Key fact: Washington state landlords have 21 days to return deposits, the same tight window as California, with double damages for bad-faith withholding.
