Landlord Sued in Washington Small Claims Court Over a Security Deposit

A tenant just filed a small claims case against you for their security deposit. Under Washington's Residential Landlord-Tenant Act, this is one of the most common — and most expensive — claims a landlord can face, because the law allows the tenant to recover up to double the deposit amount.

The 30-Day Rule Under RCW 59.18.280

Washington law requires landlords to provide a full, specific statement of the basis for retaining any deposit, required supporting documents, and any refund due within 30 days after the rental agreement ends and the tenant vacates. If you fail to do so, you are liable for the full deposit unless a statutory exception applies.

If you miss the 30-day deadline, you may also be barred from asserting a claim or defense for retaining the deposit unless circumstances beyond your control prevented timely compliance or the tenant abandoned the premises.

Double Damages

RCW 59.18.280 allows the court, in its discretion, to award up to twice the amount of the deposit for an intentional refusal to provide the required statement, documentation, or refund. This isn't automatic.

On a $2,000 deposit, that's up to $4,000 plus the plaintiff's filing and service costs. Within Washington's $10,000 small claims limit for individuals, most security deposit disputes fit comfortably.

How to Defend the Claim

Your defense depends on what happened with the deposit:

You returned it on time with proper deductions. Bring the itemized statement you mailed, proof of mailing (certified mail receipt or tracking), photos of the damage, and repair invoices. If you followed the 30-day timeline and documented everything, this is a strong defense.

You sent the statement but the tenant disputes the deductions. The dispute becomes about whether the deductions were reasonable. Bring move-in and move-out inspection reports (ideally signed by both parties), dated photos of the unit's condition, contractor estimates or repair receipts, and the lease showing what constitutes normal wear and tear. The judge compares your documentation against the tenant's.

You missed the 30-day deadline. This is harder to defend. The statute allows an exception if circumstances beyond your control prevented timely compliance or the tenant abandoned the premises. If the statement was late, you should consider settling for the deposit amount before the hearing rather than risking an award at trial.

The tenant broke the lease or owes rent. Unpaid rent and early lease termination costs can be legitimate deductions, but they need to appear in the statement sent within 30 days. Raising them for the first time at the hearing, without having included them in the statement, generally doesn't work.

What to Bring to the Hearing

• The lease agreement
• The move-in inspection report
• The move-out inspection report
• Your itemized deduction statement and proof of when it was mailed
• Dated photos of any damage (with timestamps)
• Repair invoices or contractor estimates
• Any written communication with the tenant about the deposit
• Three copies of everything (judge, tenant, yourself)

Business Entity Complications

If you own the rental property through an LLC or corporation, the small claims limit drops to $5,000 under RCW 12.40.010. Your entity must be represented by a non-attorney officer or employee — you can't hire a lawyer to appear in small claims without the judge's permission. If the tenant's claim exceeds your entity's $5,000 cap, the case may need to transfer to regular District Court civil proceedings.
