Washington Security Deposit Law: Limits and Return Deadlines

Security deposits in Washington are governed by the state Residential Landlord-Tenant Act (RLTA), chapter 59.18 RCW. This article covers how much a landlord can require before move-in, the conditions a landlord must meet to hold a deposit, the 30-day deadline to return it, what a landlord can lawfully deduct, and what happens when a landlord keeps money a tenant disputes. For the wider framework of rental rules, required notices, and tenant protections, see Washington landlord-tenant law.

How much a landlord can charge as a deposit

Washington’s Residential Landlord-Tenant Act does not cap the dollar amount of a security deposit. No state statute limits a deposit to a set number of months’ rent, so the amount is whatever the written rental agreement specifies. A deposit can be collected at all only when the tenancy is documented: under RCW 59.18.260, no deposit may be collected unless the rental agreement is in writing and the landlord gives the tenant a written checklist describing the condition of the unit at the start of the tenancy.

Nonrefundable fees are treated separately from deposits. Under RCW 59.18.285, money that is nonrefundable cannot be labeled a deposit, the rental agreement must be in writing, and it must state clearly that the fee is nonrefundable. If the agreement fails to say so, the fee is treated as a refundable deposit and comes back to the tenant under the same rules as any other deposit.

Washington also gives tenants a right to spread the up-front cost over time. RCW 59.18.610 requires a landlord, on the tenant’s written request, to allow deposits, nonrefundable fees, and last month’s rent to be paid in installments. For a lease of three months or longer the tenant can pay in three equal monthly installments; for shorter tenancies, two. A landlord is not required to offer installments when the deposits and nonrefundable fees together are no more than 25 percent of the first full month’s rent and last month’s rent is not required up front.

A landlord who refuses a proper written installment request is subject to a statutory penalty of one month’s rent plus reasonable attorneys’ fees under RCW 59.18.610.

What a landlord must do to hold a deposit

Collecting a deposit triggers two documentation duties. The first is the move-in checklist. Under RCW 59.18.260, the landlord must give the tenant a written checklist or statement, at the start of the tenancy, that specifically describes the condition and cleanliness of the unit and its fixtures, appliances, and furnishings. Both parties sign it. A landlord who collects a deposit without providing this checklist is liable to the tenant for the amount of the deposit, and the prevailing party can recover court costs and reasonable attorneys’ fees.

The second duty concerns where the money is held. RCW 59.18.270 requires the landlord to place the deposit promptly in a trust account at a financial institution and to give the tenant a written receipt plus written notice of the name, address, and location of the institution holding it. Unless the rental agreement says otherwise, the landlord keeps any interest earned on the account. If the property changes hands, the deposit transfers to the new owner’s trust account and the tenant is notified of the new location.

The 30-day deadline to return your deposit

The central deadline is 30 days. Under RCW 59.18.280, within 30 days after the rental agreement ends and the tenant vacates, the landlord must give the tenant a full and specific written statement of the basis for keeping any of the deposit, together with any refund due. The landlord meets the deadline by delivering the statement and refund to the tenant in person, or by depositing them in the U.S. mail, properly addressed with first-class postage prepaid, within those 30 days.

1. The tenancy ends and the tenant moves out

   The 30-day period begins when the rental agreement terminates and the tenant has vacated the unit. Providing the landlord a forwarding address in writing gives the landlord somewhere to mail the statement and refund.

2. The landlord compares the unit to the move-in checklist

   The landlord assesses the unit’s condition against the signed move-in checklist required by RCW 59.18.260. That checklist is what allows the landlord to charge for damage beyond normal wear and tear.

3. The landlord sends a statement and any refund

   Within 30 days, the landlord delivers or mails a full and specific written statement of any deductions plus the remaining balance, as RCW 59.18.280 requires. A deposit kept in full still requires the written statement.

4. The tenant reviews or disputes the deductions

   A tenant who disagrees with the deductions can request documentation and, if the dispute is not resolved, file a claim in court to recover the amount withheld.

What a landlord can deduct from a deposit

A deposit secures the tenant’s obligations, so a landlord can apply it to unpaid rent and other charges the tenant owes, and to the cost of repairing damage the tenant caused beyond normal wear and tear. Ordinary wear from living in the unit is not chargeable. RCW 59.18.280 ties deductions to the documentation rule: a landlord may not keep any of the deposit for the cost of repairing or replacing fixtures, equipment, appliances, or furnishings unless their condition was reasonably documented in the written move-in checklist.

Because the statement of deductions must be “full and specific,” a general note that money was kept “for cleaning and damages” does not meet the standard. The Washington State Attorney General’s office describes the deposit rules and the itemization requirement in its landlord-tenant consumer information. Keeping the checklist, dated move-in and move-out photos, and receipts is how each side supports its position if the deductions are later challenged.

When a landlord keeps a deposit improperly

The consequence for missing the deadline is defined by statute. Under RCW 59.18.280, a landlord who does not provide the required statement within 30 days is liable to the tenant for the full amount of the deposit. In an action to recover the deposit, the prevailing party is additionally entitled to the cost of the suit or arbitration, including a reasonable attorneys’ fee.

There is a time limit on bringing the claim. An action by the landlord to recover sums beyond the deposit for damage the tenant caused, and by extension a deposit dispute tied to it, must generally be started within three years of the end of the rental agreement or the tenant’s abandonment of the unit, under RCW 59.18.280. Deposit disputes that fit within the small claims dollar limit are commonly filed in the district court’s small claims department, where the process is designed for people without lawyers.
