Seattle Commercial Eviction Attorney

Consider this hypothetical: your commercial tenant in Capitol Hill missed last month’s rent. You have a clause in the lease giving you the right to terminate immediately for nonpayment. You send a termination notice. You think you’re done. You’re not.

That termination notice and the 3-day pay-or-vacate notice required by RCW 59.12.030(3) are two different legal acts. The Washington Court of Appeals has held that even when a lease gives a landlord immediate termination rights, the landlord still must serve the statutory notice if it wants to use the expedited eviction process. Skip that step and the case gets dismissed. The clock resets. The rent keeps not coming in.

K&S Canon handles commercial evictions in King County Superior Court. We file unlawful detainer actions under RCW Chapter 59.12, understand the procedures that separate a case that moves on the priority calendar from one that gets kicked back on a technicality, and know what commercial landlords are often surprised to learn: the remedies available in commercial evictions are significantly stronger than in residential ones.

SHORT ANSWER No. Seattle’s Just Cause Eviction Ordinance (SMC 22.206.160) applies to residential tenancies only. Commercial landlords in Seattle do not need just cause to evict a commercial tenant. Commercial evictions are governed entirely by Washington’s Unlawful Detainer Act under RCW Chapter 59.12, which imposes no just-cause requirement for commercial properties.

This is one of the most persistent misconceptions I see from commercial landlords, particularly those who also own residential properties. Seattle has built an extensive set of residential tenant protections — the Just Cause Eviction Ordinance (SMC 22.206.160), the winter eviction ban (December 1 through March 1), mandatory right to counsel for residential tenants who cannot afford an attorney, and more. None of those apply to commercial tenancies.

When a commercial landlord asks whether they need a good reason to evict a commercial tenant in Seattle, the answer is the same as it would be anywhere else in Washington: the lease terms and RCW 59.12 govern. No just cause required. No Seattle ordinance overlay. The Seattle SDCI’s own page on the Just Cause Eviction Ordinance makes this clear — it applies to residential housing units, not commercial properties.

WHAT ALSO DOES NOT APPLY TO SEATTLE COMMERCIAL EVICTIONS •         Seattle’s winter eviction ban (December 1–March 1) — residential only •         The 14-day pay-or-vacate notice — residential only (RCW 59.18) •         Tenant right to free legal counsel — residential only (Seattle city law) •         Eviction resolution pilot program — residential only, expired July 2023

SHORT ANSWER Commercial evictions in Seattle are governed by RCW Chapter 59.12, not the Residential Landlord-Tenant Act. Key differences: the notice period for nonpayment is 3 days (not 14), no just cause is required, and commercial landlords can recover double damages under RCW 59.12.170 — a remedy that does not exist in residential evictions.

The framework matters from the first step. Every commercial eviction is different — the notice that works in one situation fails in another because of how the lease is drafted or how service was accomplished. But the starting framework is always the same: RCW Chapter 59.12, not RCW 59.18.

Factor	Commercial (RCW 59.12)	Residential (RCW 59.18)
Notice for nonpayment	3-day pay-or-vacate	14-day pay-or-vacate
Notice for lease violation	10-day	10-day
Just cause required in Seattle?	No	Yes (SMC 22.206.160 + RCW 59.18.650)
Seattle winter eviction ban?	Does not apply	Applies Dec 1 – Mar 1
Double damages available?	Yes — mandatory (RCW 59.12.170)	No equivalent
Priority trial calendar?	Yes — RCW 59.12.130	No priority
Tenant right to free counsel?	No	Yes (Seattle city law)
Notice form prescribed?	No prescribed form	Yes — RCW 59.18.057

Commercial landlords who also manage residential properties sometimes use the 14-day pay-or-vacate form for commercial tenants. That form is the residential notice. It is wrong for commercial evictions. Using it requires starting over.

SHORT ANSWER A Seattle commercial eviction starts with a 3-day pay-or-vacate notice for nonpayment under RCW 59.12.030(3), followed by an unlawful detainer complaint filed at King County Superior Court, 516 Third Avenue. Commercial cases receive priority scheduling under RCW 59.12.130. After a show cause hearing, the court may issue a writ of restitution enforced by the King County Sheriff.

Steps in a Seattle commercial eviction

1.       Serve proper notice. For nonpayment: a 3-day pay-or-vacate notice under RCW 59.12.030(3). For lease violations other than rent: a 10-day comply-or-vacate under RCW 59.12.030(4). For nuisance or waste: a 3-day notice to quit with no cure option. Notice type, content, and delivery method all matter. As of July 27, 2025 (HB 1003), notices sent by mail rather than personal service require USPS Certified Mail.

2.      Wait the notice period. Count carefully. When in doubt, give an extra day rather than risk dismissal for filing too early. Weekends count toward the 3-day period. The notice is a waiting period for the landlord, not a deadline for the tenant.

3.      File the unlawful detainer complaint. Filed at King County Superior Court, 516 Third Avenue, Seattle. Filing fee: up to $197, typically split between filing and when tenant responds or an Order to Show Cause is requested. Commercial eviction cases receive priority scheduling under RCW 59.12.130.

4.      Serve the summons and complaint. Must be served by a sheriff, licensed process server, or uninvolved adult over 18. Summons is returnable between 7 and 30 days from date of service under RCW 59.12.070.

5.      Attend the show cause hearing. Both parties appear before a King County Superior Court commissioner or judge. The landlord presents evidence of the lease, the default, and proper notice. If the landlord prevails, the court issues an order for a writ of restitution.

6.      King County Sheriff enforces the writ. After obtaining the writ, the King County Sheriff’s Office serves and executes it. Budget approximately 90 days from obtaining the writ for the Sheriff to execute, based on current staffing levels. Writs with short return windows (10 or 20 days) will not be enforced.

THE LEASE TERMINATION TRAP Even if your lease gives you the right to immediately terminate for nonpayment, you still must serve the 3-day pay-or-vacate notice if you want to use the expedited unlawful detainer process under RCW 59.12. The Washington Court of Appeals has held this directly. Landlords who skip the notice step because they think their lease gave them termination rights lose the case and have to start over.

SHORT ANSWER Under RCW 59.12.170, Washington courts must award double the amount of damages assessed in commercial unlawful detainer cases. This includes past-due rent. The double-damages provision is mandatory — it cannot be applied at the court’s discretion. This remedy does not exist in residential evictions.

Most commercial landlords don’t know this.

If a commercial tenant fails to pay rent and an unlawful detainer action proceeds to judgment, the court must award twice the damages assessed — including past-due rent. This is not something the judge can choose to award or decline. Washington case law going back over a century (Hinckley v. Casey, 45 Wash. 430, 1907) establishes that the double-damages provision under RCW 59.12.170 is mandatory.

The double-damages provision applies to all commercial unlawful detainer cases, not only to nonpayment situations. A tenant who holds over after expiration of their lease term, or who remains after a notice period for a lease violation, is also subject to the double-damages award.

This provision is also part of why careful notice and procedure matters so much. A case dismissed on a technicality — wrong notice form, improper service, filing one day early — forfeits this remedy entirely until the process starts over.

SHORT ANSWER Commercial unlawful detainer actions receive priority scheduling at King County Superior Court under RCW 59.12.130. After serving the 3-day notice and filing the complaint at 516 Third Avenue, timelines vary based on court scheduling and whether the tenant contests. Once a writ of restitution is obtained, budget approximately 90 days for the King County Sheriff to execute.

There is no precise answer that applies to every case. What I can tell you is what the statute provides, what King County’s current reality looks like, and where the delays actually come from.

Stage	King County reality (2024–2026)
Notice period (nonpayment)	3 days minimum — no shortcuts
Filing complaint	Day 4 or later
Service on tenant	Within 7–30 days (summons return window)
Show cause hearing	Weeks to months depending on docket
Writ obtained (if landlord prevails)	After hearing
Sheriff enforcement	~90 days from writ issuance

Commercial cases get priority on King County’s trial calendar under RCW 59.12.130, which moves them faster than standard civil litigation. In August 2024, the court implemented new procedures under Presiding Judge Keta Shah to address eviction backlogs, including allowing cases involving health and safety risks to bypass the commissioner queue and go directly before a judge.

The Sheriff’s 90-day execution window is what surprises landlords most. Winning in court and obtaining the writ is not the end. Budget approximately 90 days after the writ is issued for the King County Sheriff’s Office to serve and execute it. That is the current operational reality, not a statutory requirement.

SHORT ANSWER The most common commercial eviction situations in Seattle involve nonpayment of rent, abandoned space where the tenant remains on the lease, and holdover tenants after lease expiration. Each follows a different notice pathway under RCW 59.12, and errors at the notice stage restart the entire process.

Nonpayment — the 3-day notice pathway

The most common situation. Tenant stops paying rent. Landlord serves a 3-day pay-or-vacate notice under RCW 59.12.030(3). If the tenant neither pays nor vacates within 3 days, the landlord files the unlawful detainer complaint at King County Superior Court. If the court finds for the landlord, double damages apply under RCW 59.12.170.

With downtown Seattle office vacancy at 35.6% as of Q4 2025, many commercial landlords are seeing tenant nonpayment from businesses that cannot sustain their leases. Office tenants are exempt from Seattle’s 2024 security deposit and guaranty caps (SMC 6.104) — the eviction process is the same either way.

Tenant abandoned the space but remains on the lease

A tenant stops operating, removes their equipment, and stops responding — but remains legally on the lease and owes rent. Whether a tenant is using the premises or not, they remain obligated for the full lease term under Washington law. If they stop paying, the 3-day notice pathway applies.

Holdover after lease expiration

Commercial lease expires. Tenant stays. This is unlawful detainer under RCW 59.12.030(1). No additional notice is required beyond the lease expiration itself — the landlord can file the unlawful detainer complaint directly. Double damages under RCW 59.12.170 apply to holdover situations as well.

Lease violation — nonpayment of additional charges

Tenant pays base rent but refuses to pay CAM charges, taxes, insurance, or other amounts required under a triple-net lease. These are lease violations, not nonpayment of base rent. The 10-day comply-or-vacate notice under RCW 59.12.030(4) applies. Drafting the notice correctly to identify the specific breach matters — courts require specificity.

SHORT ANSWER K&S Canon PLLC handles commercial evictions in King County Superior Court under RCW Chapter 59.12. Our office at 1200 5th Avenue, Suite 1950, Seattle is approximately 0.7 miles from King County Superior Court at 516 Third Avenue. Call (206) 507-4009.

We regularly handle unlawful detainer proceedings for commercial landlords in Seattle and King County — drafting and serving notices, filing complaints at King County Superior Court, appearing at show cause hearings, and coordinating writ enforcement with the King County Sheriff. We also review commercial leases before a dispute develops, which is where the margin for prevention is largest.

 

By the time a landlord files an unlawful detainer action, the margin for correction has narrowed. Earlier intervention — reviewing a defaulting tenant’s lease, understanding what notice is required and when, assessing whether the double-damages provision is in play — costs less than restarting a dismissed case.
