Washington's just cause eviction requirements significantly limit when landlords can end tenancies. Notice content rules are detailed and recently updated.
Washington's eviction process is called an Unlawful Detainer Action and is governed by RCW 59.18 (Residential Landlord-Tenant Act). Cases are filed in superior court at the county level. Washington is one of the most tenant-protective states in the country — the 2019 Just Cause Eviction Reform Act significantly limits when landlords can terminate tenancies. Uncontested cases typically take six to nine weeks; contested cases significantly longer.
Unlawful detainer cases are filed in the superior court of the county where the property is located. Washington's just cause requirements (RCW 59.18.650) apply statewide and require landlords to specify a permitted reason for terminating most residential tenancies.
For non-payment of rent, Washington requires a 14-day written notice to pay or vacate (RCW 59.12.030). This was extended from 3 days under recent reforms. The notice must precisely state the amount owed and inform the tenant of the right to cure within 14 days.
For lease violations, Washington requires a 10-day notice to cure or vacate. For violations involving substantial waste, nuisance, illegal activity, or threatening behavior, Washington allows a 3-day notice to vacate.
For month-to-month tenancies, Washington's just cause requirements limit no-cause termination significantly. When a permitted cause applies, the notice period varies based on the cause — generally 20 to 90 days. Notices must be served by personal service, mailing and posting, or certified mail.
After the notice period expires, file an unlawful detainer complaint and summons in the superior court of the property's county. Filing fees in Washington are typically $240 to $290. Service must be completed by a process server using specific methods.
The tenant has 7 days from service to file an answer. Washington's eviction procedure includes a Show Cause hearing typically scheduled within 14 to 30 days of filing.
Washington superior court unlawful detainer hearings are formal proceedings. Bring your lease, all notices and proof of service, your rent ledger, photographs, and any documentation. Tenants can raise extensive defenses including just cause violations, habitability defenses, retaliation, and procedural challenges. Mediation is encouraged in many counties.
If you prevail, the writ of restitution is issued. Tenants can appeal and request stays. Washington's Eviction Resolution Pilot Program and other tenant assistance programs can extend the process significantly.
King County, anchored by Seattle, is Washington's most populous county. King County eviction filings go to the King County Superior Court at the Seattle Courthouse. The City of Seattle has additional tenant protections beyond state law including the Just Cause Eviction Ordinance, the Roommate Eviction Ordinance, and various rent regulation rules. Filing in Seattle requires understanding both state and local requirements.
Pierce County, anchored by Tacoma, is Washington's second-largest county. Pierce County eviction filings go to the Pierce County Superior Court in Tacoma. Tacoma also has additional local tenant protections. For detailed landlord-tenant law specific to each county — including just cause requirements, Seattle and Tacoma local ordinances, and procedural details — see King County landlord-tenant law and Pierce County landlord-tenant law.
