Washington Security Deposit Demand Letter
Direct answer
In Washington, the landlord must return the deposit within 30 days. The deadline is measured from this trigger: Termination of the rental agreement and vacation of the premises (or, if tenant abandons, within 30 days after landlord learns of the abandonment). The verified state formula is If landlord fails to provide the statement/refund within 30 days, landlord becomes liable to tenant for the full amount of the deposit; if the court finds the landlord's refusal to give the statement, documentation, or refund was "intentional," the court may in its discretion award up to 2x the deposit amount, plus the prevailing party (tenant, if they win) may recover costs and reasonable attorneys' fees. If the landlord fails to provide the initial move-in checklist (RCW 59.18.260) before collecting a deposit, landlord is liable for the full deposit amount plus costs/fees..

Statute says
"Within 30 days after the termination of the rental agreement and vacation of the premises... the landlord shall give a full and specific statement of the basis for retaining any of the deposit... together with the payment of any refund due the tenant... The court may in its discretion award up to two times the amount of the deposit for the intentional refusal of the landlord to give the statement, documentation, or refund due unless the landlord shows that circumstances beyond the landlord's control prevented the landlord from providing the statement..." (RCW 59.18.280(1)(a), (2))
What this means
Read the deadline, trigger, and penalty together before sending a letter. Match the dates in your documents to the trigger listed above, then cite RCW 59.18.260, RCW 59.18.280 (Residential Landlord-Tenant Act) and request the deposit amount supported by your records.
Worked example
Use your actual deposit amount when you write the letter. For context, median rent in Washington is $1,824 according to US Census Bureau American Community Survey via USAFacts data as of .
- Seattle-Tacoma-Bellevue, WA Metro Area: $2,000
- Portland-Vancouver-Hillsboro, OR-WA Metro Area: $1,724
- Bellingham, WA Metro Area: $1,555
- Spokane-Spokane Valley, WA Metro Area: $1,264
Example demand basis: a deposit equal to the state median rent starts at $1,824 before applying the state formula: If landlord fails to provide the statement/refund within 30 days, landlord becomes liable to tenant for the full amount of the deposit; if the court finds the landlord's refusal to give the statement, documentation, or refund was "intentional," the court may in its discretion award up to 2x the deposit amount, plus the prevailing party (tenant, if they win) may recover costs and reasonable attorneys' fees. If the landlord fails to provide the initial move-in checklist (RCW 59.18.260) before collecting a deposit, landlord is liable for the full deposit amount plus costs/fees..
