The notice must be delivered to the property owner and the prime contractor. Subcontractors and suppliers who do not have a direct contract with the owner are required to send this notice — general contractors are exempt. Failing to serve the notice on time does not eliminate lien rights for past work, but any labor or materials furnished before the 60-day window closes are permanently excluded from lien protection. Skipping the notice entirely bars a lien claim for the full contract amount on projects where notice is required. ## Who Is Required to File a Notice of Right to Claim Lien in Washington? Any subcontractor, sub-subcontractor, or material supplier who lacks a direct contract with the property owner must serve the Notice of Right to Claim Lien to preserve lien rights under [RCW 60.04.031](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.031). General contractors who have a direct contract with the owner are not required to serve this notice. That means if you're an electrical sub, a roofing subcontractor, a plumbing sub, or a lumber yard delivering material to the site — you must send this notice. It applies to private projects only. Public works projects in Washington are governed by a separate payment bond statute (RCW 39.08), not the mechanics lien statute. ## When Is the Washington Notice of Right to Claim Lien Due? The notice must be served no later than 60 days after first furnishing labor, materials, or equipment to the project, per [RCW 60.04.031](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.031). The clock starts on the first day you actually perform work or deliver materials — not the date your contract is signed, not the date of the purchase order. If you serve the notice after the 60-day window has already opened, your lien protection is limited to work and materials furnished in the 60 days before the notice was served. Anything outside that window is unprotected. Send the notice on day one of first furnishing, not day 59. ## How Do You Serve the Washington Notice of Right to Claim Lien? Under [RCW 60.04.031](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.031)(4), the notice must be served by certified mail with return receipt requested, personal delivery, or any other method that provides a written record of delivery. Certified mail is the standard method in practice because it creates a dated, documented delivery record. Address the notice to the owner of the property and the general contractor. If you don't know the owner's name or address, you can pull the property ownership information from the county assessor's records — that information is public. Use the legal address of the property, not just the job site address, when addressing the owner. [Washington lien notice resources](/resources/washington-notice-of-right-to-claim-lien) The notice itself must include specific content under [RCW 60.04.031](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.031)(1): - The name and address of the person furnishing labor, materials, or equipment - The name of the person who hired the claimant (your direct customer on the project) - A general description of the labor, materials, or equipment furnished - The name of the owner or reputed owner of the property - The legal description or common address of the property Leaving out required fields can invalidate the notice. Use an attorney-reviewed, state-compliant form. ## What Is the Deadline to File the Mechanics Lien Itself in Washington? After the Notice of Right to Claim Lien is properly served, a subcontractor has 90 days from the last date of furnishing labor or materials to file the mechanics lien with the county recorder in the county where the property is located, under [RCW 60.04.091](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.091). The 90-day period runs from the last day you performed work or delivered materials — not from the payment due date, not from the invoice date. Missing this deadline means your lien rights are gone entirely, regardless of whether your preliminary notice was perfect. File the lien with the auditor's office (county recorder) in the county where the property sits. Washington has 39 counties, so confirm the correct county before filing. The lien claim itself must include the information required by [RCW 60.04.091](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.091)(2): - The claimant's name, address, and phone number - A description of the labor, professional services, materials, or equipment furnished - The last date on which labor or materials were furnished - The name of the person who contracted for the work or materials - The legal description of the property - The dollar amount claimed ## How Long Do You Have to Enforce a Washington Mechanics Lien? A recorded mechanics lien in Washington must be enforced by filing a lawsuit within 8 months of the date the lien was recorded, under [RCW 60.04.141](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.141). If you don't file suit within that window, the lien expires and becomes unenforceable — the property owner can then file for a release of the lien. Eight months sounds like a long time, but between negotiation attempts and attorney scheduling, it moves fast. Mark the enforcement deadline on your calendar the day you file the lien. One important nuance: if the property owner serves a written notice demanding that the claimant commence suit, the 8-month period is compressed to 30 days from receipt of that demand notice under [RCW 60.04.141](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.141). This is a common tactic owners use to accelerate lien expiration. If you receive a demand-to-sue notice, contact an attorney immediately. ## What Are the Consequences of Missing the Washington Lien Deadlines? Missing either deadline — the 60-day notice window or the 90-day lien filing window — results in a permanent loss of lien rights for the affected work. There is no cure period, no grace extension, and no ability to file late. Washington courts have consistently held that the statutory deadlines are strict. A defective or late notice is treated the same as no notice. According to Rabbet's 2024 Construction Payments Report, 82% of contractors face payment waits of over 30 days — and without a timely lien notice, the only remaining option when a payment dispute arises is a breach-of-contract lawsuit, which is slower and more expensive than enforcing a lien. [lien deadline calculator](/tools/lien-deadline-calculator) ## Does Washington Require a Preliminary Notice on Public Projects? No. The Washington mechanics lien statute (RCW 60.04) applies only to private construction projects. On public works projects — anything involving a state agency, county, city, or other public body — the property itself cannot be liened. Instead, Washington requires that prime contractors post a payment bond on public works contracts over $35,000 under RCW 39.08.010. Subcontractors and suppliers must file a claim against that payment bond. The deadline to file a payment bond claim on a Washington public works project is 30 days after completion of the prime contract, or 4 months after the last date of furnishing labor or materials, whichever is earlier, under RCW 39.08.030. These are different deadlines from the private lien statute — do not confuse them. ## What Are Washington's Rules on Lien Waivers? Washington does not have a statutory lien waiver form — there is no mandated state form you're required to use. However, lien waivers are routinely used in Washington construction contracts, and courts will enforce them as contract documents. Unconditional lien waivers signed before payment is received can extinguish your lien rights even if payment never comes. Conditional lien waivers are safer because they only take effect once the triggering payment actually clears. Read every lien waiver carefully before signing. If a GC sends you a broad, unconditional waiver for a progress payment, that document may waive rights beyond the payment it covers. ## How Much Does It Cost to File a Washington Mechanics Lien? Filing fees vary by county. Most Washington counties charge between $100 and $200 to record a lien document with the county auditor, though fee schedules are set locally and subject to change. That fee covers the recording only — it does not include the cost of preparing the lien document, serving the notice of right to claim lien, or any attorney fees if enforcement is needed. In 2024, preliminary notices were filed on construction projects valued at over $22.7 billion across the United States, according to Lienser (via DocJoist Construction Payment Statistics, 2024) — a number that reflects how seriously subcontractors treat lien protection as standard business practice. Sending the preliminary Notice of Right to Claim Lien via LienFlash costs $24.99 and includes a state-compliant, attorney-reviewed form plus USPS Certified Mail with Return Receipt. USPS Certified Mail itself costs $4.85 as a base fee in 2026, per USPS Notice 123, before postage — the larger cost is usually the time and administrative overhead of generating a compliant notice and tracking the delivery. LienFlash handles both. [lien deadline directory](/deadlines) ## Frequently Asked Questions ### Does a general contractor in Washington need to send a Notice of Right to Claim Lien? No. General contractors with a direct contract with the property owner are exempt from the notice requirement under [RCW 60.04.031](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.031). The notice requirement applies to subcontractors, sub-subcontractors, material suppliers, and equipment lessors who do not have a direct contractual relationship with the property owner. ### What happens if I miss the 60-day notice window in Washington? Missing the window does not eliminate your lien rights entirely, but it limits them. Under [RCW 60.04.031](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.031), a late notice protects only the labor and materials furnished in the 60 days prior to the date the notice was served. Any work or materials furnished before that 60-day lookback period are permanently excluded from lien coverage. Serving the notice as early as possible is always the right move. ### Can I file a mechanics lien in Washington without filing the preliminary notice first? If you are a subcontractor or supplier without a direct owner contract, failing to serve the Notice of Right to Claim Lien before filing a lien puts your lien at serious risk of being ruled invalid. The preliminary notice is a prerequisite to lien rights for those parties required to send it under [RCW 60.04.031](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.031). General contractors do not have this restriction. ### Where do I file a mechanics lien in Washington state? File with the county auditor's office in the county where the property is located. Washington has 39 counties, so confirm the correct county using the property's legal description or address. Filing in the wrong county will not create a valid lien against the property. ### Does the Washington mechanics lien law apply to residential projects? Yes. RCW 60.04 applies to both commercial and residential private construction projects. However, Washington has additional requirements for owner-occupied residential properties — under [RCW 60.04.035](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.035), a subcontractor claiming a lien on an owner-occupied residential property must also give written notice of the right to claim a lien to the owner at or before the time of first furnishing labor or materials. Residential lien law in Washington has added complexity; consult an attorney if you are working on an occupied single-family home. ### How do I serve the Notice of Right to Claim Lien in Washington? Under [RCW 60.04.031](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.031)(4), serve by certified mail with return receipt requested, personal delivery, or another method that provides written proof of delivery. Certified mail is the most common method because the tracking record and return receipt create clear, timestamped evidence of delivery. Keep the Certificate of Mailing and the signed return receipt card. ### Can an owner bond around a Washington mechanics lien? Yes. Under [RCW 60.04.161](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.161), a property owner can record a surety bond in an amount equal to 150% of the lien claim to discharge the lien from the property. This does not eliminate the debt — it just moves the security from the real property to the bond. The claimant's lien rights then attach to the bond, and the claimant must still enforce within the original 8-month period. ### What is the difference between a Washington mechanics lien and a stop notice? Washington does not have a stop notice remedy for private projects. The primary payment protection tool for private work is the mechanics lien under RCW 60.04. For public works, the payment bond claim under RCW 39.08 is the equivalent remedy. Stop notices are a statutory tool available in some other states — California being the most notable — but they do not exist in Washington's private construction lien framework. ## Protect Your Lien Rights Today Washington's 60-day notice window moves faster than most subcontractors expect. The safest approach is to send the Notice of Right to Claim Lien on the day you first show up to a job — not after the invoice goes unpaid, not when a payment dispute starts brewing. By then, the window may already be partially closed.
