Short answer: In a Washington security deposit lawsuit, a landlord who misses the 30-day statement deadline owes the full deposit and, under RCW 59.18.280(2), is generally barred from raising any defense for keeping it; a court may award up to twice the deposit for an intentional refusal. You can sue in the district court’s small claims department for up to $10,000 as an individual under RCW 12.40.010.
Washington also demands proof from the landlord, not just a list. Under RCW 59.18.280(1)(b), the statement must include copies of estimates or paid invoices, and the landlord’s own labor has to be shown in hours and an hourly rate. A deduction that arrives without that backup is weak from the start.

Check the Move-In Checklist First
Before you think about court, find the checklist you signed at move-in. Under RCW 59.18.260(2), no deposit may be collected unless the rental agreement is in writing and the landlord provides a written checklist describing the condition of walls, flooring, furniture, appliances and other items at the start of the tenancy. Both sides must sign and date it.
The consequence is strong. If the landlord took a deposit without that checklist, RCW 59.18.260(5) makes the landlord liable to you for the amount of the deposit, and the prevailing party may recover court costs and reasonable attorneys’ fees. Even with a checklist, RCW 59.18.280(1)(c) bars charges for fixtures, appliances or furnishings whose condition the checklist did not reasonably document.
What the Landlord Owes You Within 30 Days
The 30 days run from the end of the rental agreement and your move-out, or from when the landlord learns you abandoned the unit. Within that time, RCW 59.18.280(1)(a) requires a full and specific statement of why any money is kept, plus any refund due. Mailing it first-class to your last known address counts. So give a forwarding address in writing.
No deposit money can be kept for wear from ordinary use, for carpet cleaning unless the landlord documents wear beyond ordinary use, or for more than the cost of fixing only the damaged part of an item. See our guide to normal wear and tear for examples that come up in Washington cases.
Preparing Your Washington Security Deposit Lawsuit
Washington does not make a demand letter a condition of suing over a deposit. A written demand is still useful: it gives the landlord a last chance and becomes an exhibit showing an intentional refusal if ignored. Our deposit demand letter page explains what to say; for Washington, cite RCW 59.18.280 and list any missing invoices.
The small claims department of each district court hears money-only cases up to $10,000 for a natural person and $5,000 for other plaintiffs, under RCW 12.40.010. Grant County District Court explains that a claim generally must be filed in the district court of the county where the defendant lives, with exceptions in RCW 3.66.040.
Fees and representation
Under RCW 12.40.020, the filing fee is $35 plus any surcharge authorized for counties that fund a dispute resolution center. The total therefore varies: Grant County District Court’s page gives $35 or $45, and the Attorney General’s small claims guide gives $35 or $50. Service by sheriff or process server costs extra, though the AG notes certified mail with return receipt is an alternative.
Lawyers are kept out. RCW 12.40.080(1) says no attorney, legal paraprofessional or anyone other than the plaintiff and defendant may take part without the judge’s consent.
Penalties a Washington Judge Can Order
- Late or missing statement: liability for the full deposit, and the landlord may not raise any claim or defense for keeping it unless circumstances beyond the landlord’s control caused the delay or you abandoned the unit (RCW 59.18.280(2)).
- Intentional refusal: up to two times the deposit, at the court’s discretion, subject to the same exceptions.
- Costs and fees: the prevailing party in a deposit suit gets the cost of suit, including a reasonable attorneys’ fee.
That fee-shifting rule cuts both ways. If you sue and lose, the landlord can ask for costs too, so build the file before filing.

Example: A Tacoma Renter
Jordan’s lease in Tacoma ends March 31, 2026, and Jordan moves out that day after emailing and mailing a forwarding address. The 30-day deadline is April 30, 2026. On May 6, a letter arrives keeping $700 of a $1,600 deposit for “painting,” with no invoice.
Because the statement was late, RCW 59.18.280(2) makes the landlord liable for the full $1,600 and bars the painting defense unless the landlord proves something beyond its control caused the delay. If the judge finds the refusal intentional, the award could reach twice the deposit, $3,200. Jordan files in Pierce County District Court’s small claims department, under the $10,000 individual limit, and pays the posted filing fee.
After the Hearing: Appeals and Collection
Appeals in small claims are limited. RCW 12.40.120 bars any appeal where the amount claimed was under $250, and bars an appeal by the party who chose small claims if that party claimed less than $1,000. A landlord who appeals must post a bond of twice the judgment and costs or twice the amount in controversy, whichever is greater, under RCW 12.36.020.
Collection has a built-in timetable. Under RCW 12.40.105, the judgment becomes a district court civil judgment and grows by statutory costs, post-judgment interest and enforcement costs, including reasonable attorneys’ fees. If the landlord does not pay within 30 days after entry on the judgment docket, garnishment and execution may issue, and you can file the judgment with the superior court for its lien docket.
RCW 59.18.280 sets no deadline for filing a deposit suit. Moving quickly keeps your invoices and photos easy to find.
Frequently Asked Questions
Can my Washington landlord keep money for repairs without showing receipts?
Not properly. RCW 59.18.280(1)(b) requires copies of estimates or invoices with the statement, and for in-house work, a statement of time spent and the hourly rate. Missing documentation is a strong argument at the hearing.
I never signed a move-in checklist. What can I recover?
RCW 59.18.260(5) makes a landlord who collected a deposit without a written checklist liable for the amount of the deposit, plus court costs and reasonable attorneys’ fees to the prevailing party. That claim is separate from any RCW 59.18.280 claim.
Can I bring my lawyer to small claims?
Only with the judge’s consent under RCW 12.40.080. Since the prevailing party can still recover attorneys’ fees in a deposit case, some tenants hire a lawyer and file a regular district court case instead.
How fast can I garnish the landlord’s bank account?
RCW 12.40.105 allows garnishment and execution if the judgment is unpaid 30 days after it is entered on the district court judgment docket. The clerk gives you a certified copy of the judgment for no added fee.
Is the Washington small claims limit different for an LLC tenant?
Yes. RCW 12.40.010 sets $10,000 for a natural person and $5,000 for all other plaintiffs, such as a business that signed a lease.
