Washington Eviction Process: Notice Periods, Timeline, and Costs

RCW 59.12.030(3) gives residential tenants under the Residential Landlord-Tenant Act 14 days after service to pay or vacate, and RCW 59.18.057 requires the notice to be in substantially the form the Attorney General publishes — using your own wording is a common ground for dismissal. Only 'rent' as defined in RCW 59.18.030 may be demanded, meaning recurring periodic charges for use and occupancy; late fees, damages, and attorney fees cannot be included and cannot support a nonpayment case. Service follows RCW 59.12.040: personal delivery, or leaving a copy with a person of suitable age plus mailing, or posting conspicuously plus mailing. When you serve by mail you must add five days before filing, and the notice must state the specific calendar date by which the tenant must pay or vacate.

RCW 59.12.030(4) and RCW 59.18.650(2)(b) give the tenant at least 10 days after service to remedy a breach of a lease covenant. Waste, nuisance, unlawful business, or a serious act on the premises gets a three-day notice to quit with no right to cure under RCW 59.12.030(5), and four documented lease violations in a 12-month period support a 60-day termination notice.

Washington abolished no-cause termination of residential tenancies. Under RCW 59.18.650 you may only end or decline to continue a tenancy for one of the enumerated causes, each with its own notice period: 90 days for owner or family move-in, 90 days for sale of a single-family home, 120 days for demolition or substantial rehabilitation, 30 days if the unit is condemned or uninhabitable, and 60 days for other good cause based on a legitimate economic or business reason. Several cities layer additional restrictions on top.

Unlawful detainer is a Superior Court action in the county where the property is located. RCW 36.18.020(2)(a) sets a $45 statutory unlawful detainer filing fee, but county clerk surcharges push the real total to roughly $135 for an uncontested residential case and $250 or more once an answer is filed or you request an order to show cause, plus sheriff service and writ execution costs.

The eviction summons under RCW 59.18.365 tells the tenant a specific date and 5:00 p.m. deadline to respond in writing, and RCW 59.12.070 requires that date to be not less than seven nor more than 30 days from service. A tenant who does not respond by the deadline can be defaulted, but Washington courts vacate defaults readily and most cases move to a show cause hearing.

Fourteen days of notice (plus five more if you served by mail), a summons giving the tenant seven to 30 days to respond, a show cause hearing, and then a writ of restitution that the sheriff must serve and cannot execute for at least three days. Washington's right-to-counsel program for low-income tenants and eviction-resolution requirements in some counties routinely add weeks.

RCW 59.18.290 makes it unlawful for a landlord to remove or exclude a tenant except under a court order, so lock changes and hauling out belongings are prohibited; the tenant may recover possession or terminate the lease and recover actual damages plus costs and reasonable attorney's fees. RCW 59.18.300 separately makes it unlawful to intentionally cause termination of a tenant's water, heat, electricity or gas except for brief repairs, and exposes you to actual damages plus statutory damages of up to $100 for each day the tenant is without the service, again with attorney's fees. Only a sheriff executing a writ of restitution may remove anyone.

HB 1003 (2025) required notices served under RCW 59.12.040 to state the specific date by which the tenant must vacate or comply and mandated certified mail for the mailing component. HB 2664, chapter 144, Laws of 2026, effective June 11, 2026, removed the certified mail requirement while keeping the requirement that a copy be mailed from within Washington and the five extra days before filing. HB 1217 (2025) capped rent increases and lengthened rent-increase notice to 90 days, and gives tenants an eviction defense where the claimed rent reflects an unlawful increase.

Washington punishes form errors harder than almost any state. The 14-day notice must track the Attorney General's mandated form under RCW 59.18.057, must state an actual calendar date, and must demand only rent — including a late fee in the total is a routine reason cases get dismissed. The certified mail requirement that HB 1003 added in 2025 was repealed effective June 11, 2026, so guides written in the last year may tell you to use certified mail when regular first-class mail deposited from within Washington is now sufficient; either way you must add five days before filing. Remember that no-cause termination no longer exists for residential tenancies, and Seattle, Tacoma, Burien, Federal Way and others add local just-cause and winter eviction restrictions on top of state law. Given the mandated forms and the tenant right-to-counsel program, most small landlords here use an attorney.
