Statute
§ 59.18.280
Revised Code of Washington
Under RCW § 59.18.280, your landlord has 30 days after the termination of your rental agreement AND your vacating the premises — both events — to return your security deposit or provide a written, itemized statement of any deductions. (This deadline was extended from 21 to 30 days by a 2023 amendment — many outdated sources still cite the old figure.)
If the landlord fails to meet the deadline or withholds your deposit improperly, you may recover:
So a $1,500 deposit intentionally withheld can support a court judgment of up to $3,000 — and the 2× is measured against the whole deposit even if only part was withheld. Most landlords settle quickly once they realize you know the law.
Watch for outdated info: Washington’s deadline was extended from 21 to 30 days by HB 1074, effective July 23, 2023. Many secondary sources still cite the old 21-day figure — your letter uses the current 30-day rule. A move-in checklist and documentation of deductions are required, or the landlord loses the right to retain.
Good to know: There is no statewide deposit cap, though Seattle caps deposits and move-in fees at one month’s rent. Deposits must be held in a trust account.

Some cities layer their own security deposit rules on top of state law — and some don't. Here's where Washington's major cities stand.
30 days after you move out.
Missing the 30-day deadline makes the landlord liable for the full deposit and bars any retention claim or defense; for an intentional refusal, a court may additionally award up to twice the amount of the DEPOSIT itself — not merely the portion withheld — under § 59.18.280(2).
