What Is a Mechanics Lien in Washington State — Complete 2026 Guide
Washington mechanics lien law requires subcontractors and suppliers to deliver a Potential Lien Notice to the property owner before recording a lien. The filing deadline is 90 days from last furnishing under RCW 60.04. Enforcement must begin within 8 months of recording.
Washington Preliminary Notice Requirement
Washington subcontractors and material suppliers must serve a Potential Lien Notice (also called a preliminary notice) on the property owner within 60 days of first furnishing labor or materials on the project under RCW 60.04.031. Failure to serve this notice limits lien rights to work furnished within the 60 days before the notice was served. The notice must go to both the property owner and the prime contractor.
Washington 90-Day Filing Deadline
After last furnishing labor, materials, or professional services on the project, Washington lien claimants have 90 days to record a claim of lien with the County Auditor in the county where the project is located. This 90-day deadline applies to all claimant types regardless of tier.
Where to File in Washington
Washington mechanics liens are recorded with the County Auditor in the county where the project property is located. Unlike most states that use a County Recorder, Washington uses the County Auditor's office. Major filing offices include the King County Auditor (Seattle), Pierce County Auditor (Tacoma), Snohomish County, and Clark County (Vancouver).
Washington Lien Enforcement — 8 Months
After recording a claim of lien in Washington, the claimant must enforce the lien by filing a foreclosure lawsuit within 8 months of the date the lien was recorded. Washington's 8-month enforcement window is longer than most states and gives claimants meaningful time to negotiate before litigation.
