Washington Construction Lien Laws Explained for Subcontractors
Last updated: July 2025
Washington subcontractors, material suppliers, and equipment lessors must serve a Notice of Right to Claim Lien within 60 days of first furnishing labor, materials, or equipment to protect their mechanics lien rights on private construction projects, under RCW 60.04.031. The notice must be sent to the owner and the prime contractor via personal service or first-class mail with certificate of mailing, or certified mail. Missing that 60-day window does not automatically void all lien rights — but it eliminates protection for work or materials furnished before the notice was served. Failing to serve the notice at all bars a subcontractor from filing an enforceable mechanics lien against the property. Washington has no Notice of Right to Claim Lien requirement for general contractors contracting directly with the owner.
Who Is Required to File a Notice of Right to Claim Lien in Washington?
Any party who does not have a direct contract with the property owner must serve a Notice of Right to Claim Lien to preserve mechanics lien rights on private projects. That means subcontractors of all tiers, material suppliers, equipment lessors, and design professionals who contract with the GC or a lower-tier sub — not the owner — are all subject to the requirement under RCW 60.04.031. General contractors (prime contractors with a direct owner contract) are exempt from filing a preliminary notice, but they still have their own lien recording deadlines. If you are an electrical sub, plumber, roofer, HVAC tech, drywall installer, or painter working under a GC on a private job in Washington, you need to file this notice.
What Is the Deadline to Serve the Notice in Washington?
The deadline is 60 days from the date you first furnished labor, materials, or equipment on the project — not 60 days from when the job finishes. This is a hard cutoff under RCW 60.04.031. The practical consequence is that you must track your first-furnishing date job by job, because the clock starts the moment your crew steps on site or your first delivery lands. If you serve the notice late — say, on day 70 — your lien rights are only protected for work performed within the 60 days before service. Everything before that is unprotected. Most experienced subs file the notice as soon as they mobilize or receive a signed subcontract, not on day 59.
Who Must Receive the Notice of Right to Claim Lien?
Under RCW 60.04.031(1), the notice must be sent to two parties: the property owner (or reputed owner) and the prime contractor. If there is a construction lender on the project, Washington law does not separately require notice to the lender for lien preservation purposes — but including them is considered best practice to put all parties on record. The owner's and GC's names and addresses should be pulled from the building permit, the subcontract itself, or a title search. Serving the right parties at the right addresses is not a formality — a notice sent to a wrong address or a wrong entity can be treated as insufficient.
How Must the Notice Be Delivered?
Washington statutes allow three delivery methods for the Notice of Right to Claim Lien: personal service, first-class mail with a certificate of mailing, or certified mail with return receipt. Under RCW 60.04.031(2), the notice is considered served on the date of mailing if you use certified or first-class mail with certificate. Certified mail with return receipt is the gold standard because it gives you documented proof of both mailing and delivery — critical if the owner or GC disputes receipt and you end up in court. USPS Certified Mail is $4.85 in 2026 as the base service fee, per USPS Notice 123, making it one of the cheapest forms of legal protection available in construction.

What Are the Deadlines to Record a Mechanics Lien in Washington?
After serving the preliminary notice, you have a separate deadline to actually record the mechanics lien itself if you go unpaid. Under RCW 60.04.091, a mechanics lien must be recorded with the county auditor in the county where the property is located no later than 90 days after the last date you furnished labor, materials, or equipment on the project. "Last date furnished" means the last substantive work, not a callback to fix a punch list item — courts distinguish between completion of contracted work and minor warranty repairs. Recording is not the same as serving a copy; after recording, you must serve a copy of the recorded lien on the property owner within 14 days of recording, per RCW 60.04.091(2).
How Long Do You Have to Enforce a Mechanics Lien in Washington?
Recording a lien is not the end of the process — it is a preservation step. Under RCW 60.04.141, you must file a lawsuit to enforce the lien within 8 months of the date the lien was recorded. If you miss that window, the lien expires and becomes unenforceable, even if the underlying debt is still owed. Eight months sounds like a long time until you factor in attorney scheduling, mediation attempts, and the time it takes to gather documentation. Mark the enforcement deadline on your calendar the same day you record the lien. Some subcontractors settle during the 8-month period precisely because the owner knows the lien will be enforced — the notice creates real leverage.
What Are the Rules for Public Projects in Washington?
Mechanics liens cannot be filed against public property in Washington — no subcontractor can lien a state highway, school, or government building. The protection mechanism on public projects is a payment bond claim under the Little Miller Act (RCW 39.08). For public works contracts over $35,000, the prime contractor is required to post a performance and payment bond. Subcontractors and suppliers who go unpaid can make a claim against that bond. The deadline to file a bond claim on a public project is generally within 30 days after the subcontractor's last day of furnishing labor or materials for projects where a retainage bond is used, but bond claim deadlines vary by contract structure — always read the bond itself and consult the contract documents.
What Happens If You Miss the Notice Deadline?
Missing the 60-day preliminary notice deadline in Washington does not mean you have no options — it means your options are significantly weaker. You lose lien rights on all work furnished before the notice was served. If you served the notice on day 75, you can only lien for work done in the 60 days preceding that service date. Beyond lien rights, you may still have contract claims, unjust enrichment claims, or the ability to pursue payment through small claims court depending on the dollar amount. But none of those remedies are as fast or as effective as a mechanics lien. According to Rabbet's 2024 Construction Payments Report, 82% of contractors already face payment waits of over 30 days — subcontractors who also lose lien rights are in the worst possible position when a GC or owner defaults.
What Must the Notice of Right to Claim Lien Include?
Washington's Notice of Right to Claim Lien has specific content requirements under RCW 60.04.031. The notice must state: the name and address of the person claiming the lien, the name of the person who contracted with the claimant (typically the GC or upper-tier sub), a description of the labor, materials, or equipment provided, the legal description or street address of the property, and the name of the property owner or reputed owner. Washington also requires that the notice include specific statutory language informing the owner of their right to withhold funds from the contractor to cover the claimant's potential lien. Using a pre-reviewed, state-compliant form eliminates the risk of a defective notice that a court could refuse to enforce.
Frequently Asked Questions
Does a general contractor in Washington need to file a preliminary notice?
No. General contractors who have a direct contract with the property owner are exempt from the Notice of Right to Claim Lien requirement under RCW 60.04.031. The notice requirement applies to subcontractors and suppliers who do not have a direct contract with the owner.
What is the lien recording deadline in Washington?
Under RCW 60.04.091, you must record your mechanics lien with the county auditor within 90 days of the last date you furnished labor, materials, or equipment on the project. Missing this deadline means you lose the right to file a lien entirely.
Can you file a mechanics lien on a public project in Washington?
No. Mechanics liens cannot be placed on public property. On public works projects, subcontractors and suppliers are protected by the payment bond posted by the prime contractor under the Little Miller Act, RCW 39.08.
What happens after you record a lien in Washington?
After recording the lien with the county auditor, you must serve a copy of the recorded lien on the property owner within 14 days, per RCW 60.04.091(2). You then have 8 months from the recording date to file a lawsuit to enforce the lien before it expires under RCW 60.04.141.
Does the 60-day notice deadline apply to all subcontractors?
Yes. Any subcontractor, material supplier, or equipment lessor who does not have a direct contract with the property owner must serve the Notice of Right to Claim Lien within 60 days of first furnishing, regardless of tier. Second-tier subs working under a first-tier sub are subject to the same rule.
Can you still get paid if you miss the preliminary notice deadline?
You lose your mechanics lien rights for work furnished before the notice window, but you may still pursue payment through contract breach claims, unjust enrichment, or small claims court depending on the amount. Those remedies are slower and less certain than a lien — the preliminary notice is your strongest tool.
How do you serve the notice on an out-of-state owner?
The same delivery methods apply: personal service, first-class mail with certificate of mailing, or certified mail with return receipt. Use the address listed on the building permit or the ownership records from the county assessor. If the owner is a corporation or LLC, service on their registered agent is also acceptable.
Does filing a Notice of Right to Claim Lien mean you are filing a lien?
No. The Notice of Right to Claim Lien is a preliminary step that preserves your ability to file a lien later if you go unpaid. It does not create an encumbrance on the property. The actual mechanics lien is a separate document recorded with the county auditor under RCW 60.04.091.
