The Washington state eviction process is a court-supervised proceeding called an unlawful detainer action, governed by the Residential Landlord-Tenant Act at RCW 59.18. A landlord cannot remove a tenant personally, change the locks, or shut off utilities. The process starts with a specific written notice, usually requires participation in the state’s Eviction Resolution Program, moves through a lawsuit and a show cause hearing in Superior Court, and ends only when a judge issues a writ of restitution directing the county sheriff to physically remove the tenant.
You Need a Just Cause
Washington does not let a landlord end a residential tenancy for any reason they choose. Under RCW 59.18.650, every eviction must be tied to a specific, enumerated cause.1Washington State Legislature. Washington Code RCW 59.18.650 – Eviction of Tenant, Refusal to Continue Tenancy, End of Periodic Tenancy The common grounds fall into a few categories:
- Nonpayment of rent after proper notice.
- A substantial breach of a material lease term that the tenant has not corrected.
- Waste, nuisance, or illegal activity on the premises.
- Owner move-in, sale, demolition, or substantial renovation requiring the unit vacant.
Picking the wrong ground, or matching the wrong notice to the violation, is one of the fastest ways to get a case dismissed. The notice form, the days allowed, and the procedure all turn on which cause applies.
Serve the Right Pre-Lawsuit Notice
Before anything is filed in court, the landlord must deliver a written notice giving the tenant a chance to cure the problem or move out. Washington uses three main notice types.2Washington State Legislature. Washington Code RCW 59.18.057 – Notice Form
14-Day Notice to Pay Rent or Vacate
For unpaid rent, the 14-day notice must state the exact dollar amount owed, including any late fees. The tenant has 14 days from service to pay in full or move out.1Washington State Legislature. Washington Code RCW 59.18.650 – Eviction of Tenant, Refusal to Continue Tenancy, End of Periodic Tenancy
10-Day Notice to Comply or Vacate
When the problem is a lease violation other than unpaid rent, the 10-day notice describes the specific breach and tells the tenant what to do to fix it. If the tenant cures within 10 days, the landlord cannot proceed on that basis.2Washington State Legislature. Washington Code RCW 59.18.057 – Notice Form
3-Day Notice to Quit
For significant property damage, nuisance, or illegal activity on the premises, the tenant gets three days to leave with no option to cure.1Washington State Legislature. Washington Code RCW 59.18.650 – Eviction of Tenant, Refusal to Continue Tenancy, End of Periodic Tenancy
How to Serve It
Every notice must include the full names of all tenants, the rental address, and the exact date the notice period expires. Serve it by handing it to the tenant, leaving it with a person of suitable age at the residence, or posting and mailing. The method matters because it determines when the clock starts. Complete a declaration of service documenting how and when the notice was delivered. Missing or defective proof of service is a frequent reason cases get thrown out.
The Eviction Resolution Program Step for Nonpayment Cases
For nonpayment of rent cases, the landlord must participate in the court-based Eviction Resolution Program (ERP) before the court will hear the unlawful detainer action.3Washington State Legislature. Washington Code 59.18.660 – Eviction Resolution Program
When serving the 14-day pay-or-vacate notice, the landlord must also provide an additional notice informing the tenant about the ERP. That additional notice must include contact information for the local dispute resolution center, information about the county’s housing justice project, and a statement that failing to respond within 14 days may result in the landlord filing a lawsuit. Copies of both notices go to the local dispute resolution center at the same time they are served on the tenant.3Washington State Legislature. Washington Code 59.18.660 – Eviction Resolution Program
Here is where landlords get stuck. The court will not hear a nonpayment eviction unless the landlord has obtained a certification of participation from the dispute resolution center. Filing a complaint without it wastes the filing fee.
Filing the Unlawful Detainer Lawsuit
Once the notice period runs out and the tenant has neither cured nor vacated, the landlord prepares two documents: a Summons and a Complaint for Unlawful Detainer. The Complaint names every adult occupant, describes the property, and lays out the facts supporting eviction, including every notice served and when. The Summons follows a specific statutory format set by RCW 59.18.365.4Washington State Legislature. Washington Code RCW 59.18.365 – Unlawful Detainer Action, Summons, Form
The statutory summons tells the tenant their written response must be received by a specific deadline or they lose the right to defend themselves. It also notifies low-income tenants that they may qualify for a court-appointed attorney at no cost.4Washington State Legislature. Washington Code RCW 59.18.365 – Unlawful Detainer Action, Summons, Form
File both documents with the Superior Court clerk in the county where the property sits and pay the filing fee. Fees vary by county. In King County, the base fee for a residential unlawful detainer is $135, with an additional $112 due if the tenant files an answer or the court schedules a show cause hearing.5King County. Superior Court Clerk’s Office Fee and Payment Information Check with your local clerk for exact amounts.
Serving the Summons and Complaint
After filing, the tenant must be formally served with the Summons and Complaint. A professional process server or any neutral adult who is not a party to the case can handle this. If personal service fails after at least three attempts over two or more days at different times, alternative service is allowed: posting the documents in a visible spot on the property and mailing copies by both regular and certified mail at least nine days before the court date.6Washington State Legislature. Washington Code RCW 59.18.055 – Service Methods
The server must complete a sworn affidavit of service and file it with the court. Without that proof on file, the case stalls.
The Show Cause Hearing
The show cause hearing is where a judge decides whether the landlord has met the legal requirements for eviction. The landlord presents evidence of the violation and proves every required notice was properly served. The tenant can raise defenses, present counterclaims, or argue that the eviction should not go forward. In straightforward cases, the judge may issue an order granting possession the same day. More complicated disputes may be set for a full trial.
Nonpayment cases carry a built-in escape hatch for the tenant. Before the court enters judgment, or within five court days after judgment, the tenant can pay all rent owed plus court costs, late fees up to $75, and any attorney fees the court has awarded. If the tenant does that, the judgment is satisfied and the tenancy continues. A tenant who holds a pledge letter from a government or nonprofit rental assistance program gets even more time and can pay up until the sheriff actually arrives.7Washington State Legislature. Washington Code RCW 59.18.410 – Eviction, Payment of Rent, Reinstatement of Tenancy A judgment in your favor is not necessarily the end of the case.
Writ of Restitution and Sheriff Removal
If the judge rules for the landlord and the tenant does not pay or vacate, the court issues a Writ of Restitution. This is the only document that authorizes the sheriff to physically remove a tenant.8Washington State Legislature. Washington Code RCW 59.18.370 – Writ of Restitution, Application, Order, Hearing Deliver the writ to the sheriff’s office and pay the service fee, which varies by county.
The sheriff serves a copy on the tenant and must wait three days before executing it.9Washington State Legislature. Washington Code RCW 59.18.390 – Writ of Restitution, Service, Execution If the tenant cannot be found, the sheriff posts the writ on the premises. Most tenants leave during this three-day window. If they do not, the sheriff returns and removes them.
What Happens to Property Left Behind
Once the sheriff executes the writ, the landlord takes possession of whatever the tenant left behind. The tenant has three days after the writ is served to submit a written request for storage. If the tenant makes that request, the landlord must store the belongings in a reasonably secure location.10Washington State Legislature. Washington Code RCW 59.18.312 – Tenant Property After Writ of Restitution
If the tenant does not request storage and does not object, the landlord may store the property anyway. If the tenant objects or never asks, the landlord must place the belongings on the nearest public property.
For stored property worth more than $250 total, the landlord must notify the tenant of a pending sale and wait 30 days before selling or disposing of it. For property valued at $250 or less, the waiting period drops to seven days after notice, but personal papers, family photos, and keepsakes cannot be disposed of in that category. The tenant can reclaim stored belongings at any time by paying the actual or reasonable storage costs, whichever is less.10Washington State Legislature. Washington Code RCW 59.18.312 – Tenant Property After Writ of Restitution
A landlord who knows the tenant has a disability that prevents them from making the written storage request must presume the tenant has requested storage unless the tenant objects in writing.
Security Deposit Accounting
Eviction does not eliminate the obligation to account for the security deposit. Within 30 days after the tenant vacates, the landlord must provide a detailed written statement explaining every deduction and return any balance. The statement must include copies of repair estimates or invoices. If the landlord or an employee did the work, the statement must show time spent and a reasonable hourly rate. Normal wear and tear cannot be deducted. Unpaid rent can be.11Washington State Legislature. Washington Code RCW 59.18.280 – Security Deposits
What You Cannot Do
Trying to force a tenant out without going through the courts carries real consequences. Changing locks, shutting off utilities, removing doors, or any other self-help measure is illegal. A tenant who is illegally removed can either recover possession or end the lease and, in either case, collect actual damages plus costs and attorney fees.12Washington State Legislature. Washington Code RCW 59.18.290 – Unlawful Removal or Exclusion of Tenant
Deliberately cutting off utilities carries a separate penalty of up to $100 per day for every day the tenant goes without service, on top of actual damages and attorney fees.13Washington State Legislature. Washington Code 59.18 – Residential Landlord-Tenant Act Two weeks without water is $1,400 in statutory damages alone, before actual damages and legal fees.
Defenses That Commonly Derail Cases
Tenants do not simply lose because the landlord filed paperwork. A few defenses come up regularly and can delay or defeat the action.
Defective notice is the most frequent. Wrong form, wrong amount, improper service, or too few days under the statute and the court will likely dismiss. The landlord can refile with a corrected notice, but that resets the entire timeline.
Retaliatory eviction is another powerful defense. If a landlord files within 90 days after a tenant reports code violations, complains to a government agency, or exercises another legal right, the court presumes the eviction is retaliatory and the burden shifts to the landlord.14Washington State Legislature. Washington Code RCW 59.18.250 – Retaliatory Actions by Landlord A tenant who wins recovers attorney fees and costs.
Habitability defenses arise when a landlord has failed to maintain the property. A tenant may argue that the landlord’s own breach of the duty to keep the unit livable excuses or offsets the unpaid rent.
Federal Rules That May Apply
Two federal laws can affect a Washington eviction.
Before a court enters a default judgment against a tenant who has not appeared, the landlord must file an affidavit stating whether the tenant is on active military duty under the Servicemembers Civil Relief Act. If the landlord cannot determine military status, the affidavit must say so, and the court may require a bond. Filing a false military status affidavit is a federal crime punishable by up to one year in prison.15Office of the Law Revision Counsel. United States Code Title 50 Section 3931 – Default Judgments, Affidavit Requirement
If the property has a federally backed mortgage or receives certain federal housing subsidies, Section 4024 of the CARES Act requires the landlord to give the tenant at least 30 days’ notice to vacate before filing. This still applies as federal law even though some federal agencies rescinded their parallel regulations in early 2026. Skipping the 30-day notice on a covered property risks dismissal.
What the Process Costs
Evictions cost more than most landlords expect. Court filing fees for a residential unlawful detainer start around $135 and can reach $247 or more if the tenant contests the case, depending on the county.5King County. Superior Court Clerk’s Office Fee and Payment Information Process server fees, sheriff fees for executing the writ, and potential storage costs for tenant belongings all add up. An attorney for an unlawful detainer case adds several hundred to over a thousand dollars depending on complexity.
For landlords who report rental income, eviction-related legal fees, court costs, and repair expenses for tenant-caused damage are generally deductible as ordinary business expenses on Schedule E. Unpaid rent, however, cannot be deducted as a loss if you use cash-basis accounting, because you never included that rent in your income in the first place.16Internal Revenue Service.
