Security deposit in Washington

Limit
No statewide dollar limit. A deposit is allowed only with a written rental agreement and a signed move-in condition checklist. Nonrefundable fees must be clearly labeled in a written lease. Some cities (such as Seattle) set their own limits.
Deadline to return it
Within 30 days after the rental agreement ends and you move out (or 30 days after the landlord learns you abandoned the unit), the landlord must give you a full and specific written statement of the reasons for keeping any part of the deposit, with supporting documents, plus any refund. Delivering it personally or mailing it first-class to your last known address counts. Give your forwarding address in writing.
Itemized list
Yes, plus proof: copies of estimates or paid invoices for damage; if the landlord did repairs, receipts for materials and a statement of the time spent and the hourly rate.
What may be deducted
Unpaid rent and other charges, and damage beyond wear from ordinary use, as allowed by the written lease. Not allowed: ordinary wear; carpet cleaning unless wear beyond ordinary use is documented; repair of items whose condition wasn't documented on the checklist; or replacing a whole item when only part was damaged.
Interest
No. Interest on the trust account goes to the landlord unless you agree otherwise in writing.
Separate account
Yes. The deposit must be put in a trust account at a Washington financial institution or licensed escrow agent. The landlord must give you a written receipt and tell you in writing the name and address of the bank. RCW 59.18.270.
Move-in checklist
Required. No deposit may be collected unless the landlord gives you a written checklist at move-in describing the condition and cleanliness of walls, floors, furniture and appliances, signed and dated by both of you; you get a copy and one free replacement. If the landlord collects a deposit without one, you can recover the whole deposit. RCW 59.18.260.
If the landlord keeps it wrongly
If the landlord misses the 30-day deadline, the landlord owes you the full deposit and can't raise any reason to keep it (unless circumstances were beyond the landlord's control). For an intentional refusal, the court may award up to twice the deposit. The winner gets court costs and attorney fees.
