No landlord starts the year planning an eviction. But when rent stops coming in, the meter starts running immediately — and in Washington, the process is more regulated, slower, and more expensive than most owners expect. Filing the wrong notice or missing a procedural step doesn’t just delay things; it can send you back to square one and add months of lost rent to the bill.
This guide walks through how to evict a tenant in Washington step by step — the required notices, the unlawful detainer court process, a realistic timeline, and what the whole thing actually costs once lost rent and turnover are counted. It applies to residential tenancies under the Residential Landlord-Tenant Act (RCW 59.18).
First rule: there is no such thing as a do-it-yourself lockout in Washington. Changing the locks, shutting off utilities, or removing a tenant’s belongings — “self-help” eviction — is illegal and exposes you to damages. Only a county sheriff, acting on a court-issued writ of restitution, can physically remove a tenant.
Before Anything Else: Washington Is a Just-Cause State
Since 2021, Washington landlords cannot end most tenancies without a legally recognized reason. Under RCW 59.18.650, “just cause” grounds include nonpayment of rent, a material lease violation, criminal activity or nuisance on the premises, an owner or immediate family member moving in, sale of a single-family home, and demolition or substantial renovation. A month-to-month tenancy needs just cause to terminate, same as any other.
Why this matters: your eviction case is only as strong as the ground you claim and the notice you serve to support it. “I’d just like the unit back” is not a ground. Get the cause wrong and the case fails before it starts.
Step 1: Serve the Correct Notice
Every Washington eviction begins with a written notice, and the notice type must match the problem:
- 14-Day Notice to Pay or Vacate — for unpaid rent. The tenant has 14 days to pay in full or move out. If they pay within the window, the eviction stops.
- 10-Day Notice to Comply or Vacate — for curable lease violations: unauthorized occupants, unauthorized pets, and similar breaches. The tenant gets 10 days to fix the problem.
- 3-Day Notice to Quit — for serious, non-curable conduct such as waste, nuisance, or illegal activity on the property. No cure period.
- No-fault cause notices — owner move-in, sale, or major renovation carry much longer notice periods, generally 60 to 120 days depending on the ground.
Notices must contain the statutorily required language and be served correctly — personal service, or substitute service plus mailing when personal service fails. Defective notices are the single most common reason eviction cases get dismissed. If the notice is wrong, you start over, notice period and all.
New for Spokane: Eviction Diversion Before You Can File (SMC 10.57)
If your rental sits inside Spokane city limits, state law is no longer the whole story. On February 2, 2026, the City Council passed Ordinance C-36808 on a 5–2 vote, adding a mandatory Eviction Prevention Program to Spokane Municipal Code Chapter 10.57 — the same chapter that already governs rental registration, rent increase notices, and the city’s ban on algorithmic rent-setting. The program took effect June 1, 2026. The backdrop: Spokane evictions climbed from roughly 1,400 per year before the pandemic to about 2,200 in 2024, and the city responded by putting a diversion process between the notice and the courthouse.
For a nonpayment eviction in the city, landlords must now complete four steps before filing an unlawful detainer:
- Serve the 14-day pay-or-vacate notice together with the city’s standardized Eviction Prevention Resources Notice — the form listing city-managed prevention programs and state-funded legal services.
- Contact an approved diversion provider from the city’s official provider directory.
- Notify the tenant in writing within 5 days that a provider has been contacted.
- Participate in good faith for up to 30 days. Good faith means showing up, responding to the provider, and genuinely working toward a resolution — it does not require accepting any particular outcome. If the case isn’t resolved after 30 days, or the tenant doesn’t engage, you may proceed to court.
The resources notice isn’t just for evictions. Under the ordinance, it must also be provided at lease signing, at every renewal, with any rent increase notice, and before seeking a mutual termination agreement. Exemptions to the 30-day process exist for conduct that seriously endangers health or safety, situations requiring eviction to prevent immediate harm or harassment, and tenants arrested for criminal activity on the property — but even exempt cases still require the notice.
Why compliance matters: skipping the diversion process can hand the tenant a legal defense to the eviction under SMC 10.57.250 — which in practice means dismissal, starting over, and another month or more of lost rent. The upside for owners: the program is backed by $2.9 million in rental assistance funding through June 2027, and a diversion payment that actually clears the balance often beats a money judgment you may never collect.
Step 2: File the Unlawful Detainer Action
If the notice period expires without payment, cure, or move-out, the next step is filing an unlawful detainer action — Washington’s formal term for an eviction lawsuit — in the superior court of the county where the property sits. For Apex PMT’s markets, that means Spokane County Superior Court for most of our portfolio.
The court issues a summons and complaint, which must be served on the tenant by a sheriff, deputy, or process server — not by you. The tenant then has seven days (excluding weekends and holidays) to file an answer.
Step 3: The Show Cause Hearing
Most Washington evictions are decided at a show cause hearing, where a judge or commissioner hears both sides. Two things owners should know going in:
- Tenants have a right to counsel. Washington was the first state to guarantee court-appointed attorneys for low-income tenants facing eviction. Expect the tenant to be represented, and expect the court to scrutinize your notice, your ledger, and your service of process.
- Documentation wins cases. A clean rent ledger, copies of every notice with proof of service, the signed lease, and a record of communications are what the commissioner will ask for. Gaps in paperwork become continuances, and continuances become weeks.
If the court rules for the landlord, it enters a judgment for possession — and, where applicable, a money judgment for unpaid rent, court costs, and fees.
Step 4: Writ of Restitution and the Sheriff
The judgment alone doesn’t return the unit. The court issues a writ of restitution, which the sheriff serves on the tenant — typically giving a final three to five days to vacate. If the tenant still hasn’t left, the sheriff returns and physically restores possession. That lockout appointment is the true end of the eviction, and sheriff scheduling adds days to every case.
The Realistic Timeline
| Phase | Typical Duration |
|---|---|
| Notice period (fault-based) | 3–14 days |
| City of Spokane nonpayment cases: pre-filing diversion (SMC 10.57) | Up to 30 days |
| Filing, summons, and service | About 1 week |
| Tenant answer window | 7 court days |
| Show cause hearing | 1–3 weeks out, longer if continued |
| Writ issued and sheriff lockout | 1–2 weeks |
| Total, uncontested | Roughly 6–12 weeks |
| Total, contested | 3–6 months |
Plan on one to three months for a clean case — and remember the rent clock started running well before you served the notice.
What an Eviction Actually Costs
The court fees are the smallest line item. Here’s the full picture for a Washington eviction:
| Cost Item | Typical Range |
|---|---|
| Court filing fee | $45–$250, varies by county |
| Service of summons and notices | $20–$100 |
| Writ of restitution service and sheriff execution | $50–$100+ |
| Attorney fees (uncontested) | $500–$1,500 |
| Attorney fees (contested) | $1,500–$10,000 |
| Lost rent (notice through lockout and turnover) | 2–4 months of rent |
| Turnover: cleaning, repairs, re-leasing | $1,000–$3,000+ |
Run the math on a typical Spokane rental. Three months of lost rent at $1,500 is $4,500 before you’ve paid a single fee. Add a contested hearing with counsel on both sides, plus repairs and vacancy on the back end, and a single eviction routinely lands between $5,000 and $10,000 all-in. A money judgment against the former tenant looks good on paper, but collecting on one is slow and often unsuccessful — treat recovered funds as a bonus, not a budget line.
The real lesson in the numbers: the cheapest eviction is the one that never happens. Rigorous screening, clear lease enforcement from day one, and early intervention on the first missed payment prevent far more losses than any courtroom strategy recovers.
Six Mistakes That Sink Washington Eviction Cases
- Self-help eviction. Lockouts, utility shutoffs, and removing belongings are illegal and create tenant claims against you.
- Defective notices. Wrong notice type, missing statutory language, or improper service — the most common fatal error.
- Sloppy ledgers. If your rent accounting can’t survive scrutiny from the tenant’s appointed attorney, expect a continuance or dismissal.
- Mishandling partial payments. Accepting rent after serving certain notices can undercut your case. Know the rules before you take the check.
- Anything that looks retaliatory. Serving a termination notice shortly after a repair request or complaint invites a retaliation defense.
- Skipping Spokane’s diversion process. For city properties, filing a nonpayment case without the required resources notice and 30-day good-faith participation gives the tenant a ready-made defense under SMC 10.57.
Keep Up With the Law — It Keeps Moving
Washington landlord-tenant law has changed nearly every legislative session in recent years — 2025’s HB 1217 alone reshaped rent increase limits and late fee rules statewide, and Spokane keeps layering city rules on top through SMC 10.57. Notices, fees, and procedures that were compliant two years ago may not be today. Before starting any eviction, confirm your notice forms and lease provisions reflect current law — our Spokane landlord-tenant guide to RCW 59.18 is a good starting point, and our owner resources blog tracks changes as they land.
