Understanding the Prelien Process on Construction Projects in Washington by Role

Subcontractors and suppliers must serve preliminary notice within 10 or 60 days depending on project type. Late notice is permissible but limits lienable amounts.

Prime/ Original / General Contractors (GCs): Prime contractors should maintain project-type documentation that affects notice windows.

Subcontractors/Trade Partners (Subs): Subs should serve preliminary notice on time to preserve full claim scope.

Second-tier Subcontractors: Second-tier parties should apply 10-day or 60-day windows based on project type.

Lower-tier Subcontractors: Lower-tier claimants should avoid late notices that shrink lienable amounts.

Material Suppliers: Suppliers should issue timely notices and track first-furnishing dates closely.

Equipment Lessors: Lessors should preserve equipment-delivery records for notice and lien timing.

Second-tier Material Suppliers: Second-tier suppliers should use project-specific deadline tracking.

Mechanic's Liens in Washington

Washington mechanics lien law requires that a lien claimant record a claim of lien within 90 days after the last date labor, materials, or equipment were furnished. For commercial projects, preliminary notice must be sent within 60 days after first furnishing, while for new single-family residential projects, notice must be sent within 10 days. Late notices are permitted, but only work provided after the retroactive window is lienable. The lien must be recorded in the county where the property is located and notice of lien must be served on the owner within 14 days of recording. A foreclosure action must be initiated within 8 months of recording, and lis pendens should be filed at that time. See RCW §§ 60.04.031, 60.04.091, 60.04.111, and 60.04.171.

Bond Claims in Washington

The claimant must also commence an action to enforce the bond claim within 6 months from the date the public agency formally accepts the project. RCW § 39.08.030 governs public project payment bonds.

Frequently asked questions (FAQs) on Washington lien processes for contractors

Do I need to send a preliminary notice to preserve my lien rights in Washington?

Yes. Subcontractors and suppliers must send a preliminary notice within 60 days of first furnishing labor or materials on commercial projects, and within 10 days for new single-family residential projects. Failure to do so limits lien rights to only materials or labor furnished after that timeframe.

When do I need to file my claim of lien?

A lien must be recorded within 90 days after the last day labor, services, materials, or equipment were furnished to the project.

What happens if I serve my preliminary notice late?

A late preliminary notice does not invalidate your lien rights completely, but limits your claim to only those labor or materials furnished after the notice and during the preceding 60 (or 10) days, depending on project type.

How long do I have to enforce a lien after recording it?

You must file a lawsuit to foreclose the lien within 8 months of recording it. If the suit is not prosecuted to judgment within 2 years, the court may dismiss it.

What notice is required for public works projects?

For public projects, a claimant must file a claim against the payment bond with the public agency within 30 days after final acceptance of the work and must commence a legal action within 6 months thereafter.
