The law in plain English
Return deadline
Under Wash. Rev. Code Sections 59.18.260 to 59.18.285; 59.18.610; 59.18.670, the deposit response usually has to be sent within 30 days of the move-out timeline described by the state rule.
Required notice
Washington generally requires the refund or an itemized deduction statement with supporting receipts within 30 days.
This dispute type
An itemized statement is how renters learn what the landlord says was damaged, what each deduction was for, and whether the withholding was timely. In Washington, failure to provide that breakdown can strengthen a renter's challenge even before the underlying repair issue is resolved.
Penalty leverage
If the withholding was wrongful or in bad faith, the exposure allowed under the statute is: Up to 2x the deposit, plus court costs and reasonable attorney's fees
