Washington Security Deposit Rules — Limits & Returns

Security deposit disputes are among the most common landlord-tenant issues in Washington. The rules for how much can be charged, what can be deducted, and when the deposit must be returned are set by statute §59.18.280; §59.18.260.

The maximum security deposit in Washington is not capped by RCW chapter 59.18 §59.18.280; §59.18.260.

Landlords may deduct for:

• Unpaid rent
• Damage beyond normal wear and tear
• Cleaning costs (if the unit was left in worse condition than at move-in)
• Other charges specifically authorized by the lease

If the landlord fails to return the deposit within 30 days or withholds it in bad faith, the penalty is: full amount of the deposit if the statement, documentation, and any refund due are not delivered personally or mailed first-class within 30 days; court may in its discretion award up to 2x the deposit for intentional refusal, plus costs of suit or arbitration and reasonable attorney fees to the prevailing party.

• Request your itemized deduction statement in writing if you do not receive it
• If the landlord does not respond, you may need to file a claim in small claims court
• Keep copies of your lease, move-in checklist, and all correspondence
