Washington security deposit law

Short answer: A Washington landlord has 30 days after the lease ends and the tenant moves out to send a full, specific statement of anything kept, with estimates or invoices, plus the refund. A landlord can't collect a deposit at all without a written lease and a signed move-in condition checklist.

Deadline to return the deposit30 days after the rental agreement ends and the tenant moves out (or 30 days after the landlord learns the tenant abandoned the unit).
Limit on how much a landlord can chargeNo statewide limit in the general landlord-tenant law (RCW 59.18). Some cities, such as Seattle, set their own limits.
Itemized list of deductionsYes. The landlord must give a full and specific statement of the reasons for keeping any of the deposit, with copies of estimates or paid invoices. For the landlord's own work, the statement must show time spent and the hourly rate, plus receipts for materials.
Interest on the depositNot owed to the tenant unless agreed in writing. The deposit must be held in a trust account at a Washington bank or licensed escrow agent, and the tenant gets a written receipt and the bank's name and address.
Penalty if the landlord breaks the rulesA landlord who misses the 30 days owes the full deposit and generally can't argue for keeping any of it. For an intentional refusal, the court can award up to twice the deposit. The winner gets court costs and attorney's fees.
