How to Legally Serve an Eviction Notice in King County (2025 Guide)
Introduction Serving an eviction notice properly is a critical first step in the legal eviction process. If done incorrectly, a landlord's case can be dismissed in court. In King County, where eviction laws are particularly tenant-friendly, landlords must follow very specific rules when delivering notices. This guide breaks down the correct ways to serve an eviction notice in 2025.
Step 1: Choose the Right Notice Before serving anything, landlords must issue the correct type of notice based on the reason for eviction:
14-Day Pay or Vacate Notice – For nonpayment of rent.
10-Day Comply or Vacate Notice – For lease violations.
3-Day Notice to Quit – For illegal activity or substantial nuisance.
90-Day Notice to Terminate Tenancy – For ending month-to-month tenancies.
Each notice must clearly state the reason for eviction, the timeline for compliance, and any applicable tenant rights, including the right to legal assistance and rental assistance resources.
Step 2: Methods of Legal Service Washington state law allows the following legal methods for serving eviction notices:
Personal Service
The notice is handed directly to the tenant.
This is the preferred and most reliable method.
Substitute Service and Mailing
If the tenant isn’t available, the notice can be left with someone of suitable age and discretion who lives at the residence and mailed to the tenant via first-class mail.
Posting and Mailing ("Nail and Mail")
If personal or substitute service isn’t possible, the notice can be posted in a conspicuous place at the rental property (typically the front door) and mailed to the tenant.
Important 2025 Updates:
In Seattle, landlords are required to file a copy of the notice with the Seattle Department of Construction & Inspections (SDCI) when using certain types of notices.
Digital delivery (email or text) is not a valid legal method unless specifically agreed to in writing by the tenant.
Proof of Service Landlords should document how and when the notice was served. Include:
A written declaration of service.
Photos (if posted on the door).
Mailing receipts, if applicable.
Common Mistakes to Avoid
Using the wrong notice type.
Failing to include all required tenant rights and legal disclosures.
Relying solely on email or text.
Not allowing the full legal timeframe to expire before taking action.
