Mechanics Lien in Washington State: Deadlines, Notice, and Priority

A mechanics lien in Washington state is a security interest that contractors, subcontractors, suppliers, architects, engineers, and surveyors can record against property they improved but weren’t paid for, and the process is governed by Chapter 60.04 RCW. The core timeline is short: send any required pre-claim notice as early as possible, record the lien with the county auditor within 90 days of your last day of work, serve the owner within 14 days after recording, and file a foreclosure lawsuit in superior court within eight months or the lien expires.¹² Miss any single step and the claim usually dies with it.

Who Can Claim a Lien

Anyone who furnishes labor, professional services, materials, or equipment for the improvement of real property may claim a lien for the unpaid contract price.³ “Improvement” is defined broadly to cover constructing, altering, repairing, demolishing, grading, filling, landscaping, and related professional services. The amount is capped at the contract price, or if no price was set, the customary and reasonable charge.⁴

One residential limit deserves attention before you file. On a single-family residential repair or remodel, a subcontractor or supplier who didn’t contract directly with the owner-occupier can only recover from funds the owner hasn’t yet paid to the general contractor at the time the pre-lien notice arrives.⁵ If the homeowner has already paid the GC in full, a downstream party may have a valid lien worth nothing.

Contractor Registration Is a Gate

Washington closes the lien system to unregistered contractors. Under RCW 18.27.114, a contractor must deliver the statutory disclosure statement to the customer, and no contractor can file or maintain a lien without proving that disclosure was delivered.⁶ A lapsed registration or a missing disclosure form ends the lien right before it starts, no matter how large the unpaid balance.

Pre-Claim Notice

Most claimants must send a written notice to the property owner (and in some situations the prime contractor) informing them of the right to claim a lien.⁵ Building the notice into the original bid or contract is the cleanest approach.

Three groups are exempt from sending the notice:

Anyone who contracted directly with the owner or the owner’s agent.
Workers whose claim is based solely on performing labor.
Subcontractors who contracted directly with the prime contractor, except in certain owner-occupied residential situations.

These carve-outs come from RCW 60.04.031.⁵

Send the notice by certified or registered mail so delivery is verifiable, or use personal service. “Received” means actual personal delivery, or three days after mailing by certified or registered mail (excluding weekends and holidays).⁵ The notice should include the claimant’s name and business address, a description of the services or materials furnished, and the identity of the party that hired the claimant. Send it early. On owner-occupied residential work, every dollar the owner pays the GC before the notice arrives is money that can never be reached through a lien.

What the Lien Document Must Contain

RCW 60.04.091 lists the required contents of a notice of claim of lien. A missing element can void the whole claim. Include:

Claimant’s name, phone number, and address.
The first and last date labor, services, materials, or equipment was furnished.
The name of the person or entity that hired the claimant.
A street address, legal description, or other description sufficient to identify the property to someone familiar with the area.
The name of the owner or reputed owner, if known; if unknown, a statement to that effect.
The principal amount claimed, excluding interest and attorney fees.

All of these come from the statute.¹

The claimant (or an authorized representative for an entity) must sign the document under penalty of perjury, affirming the claim is true and correct, and the signature must be acknowledged as required by Chapter 64.08 RCW, which usually means notarization. Failing to comply with the signing requirements invalidates the lien and forfeits the right to claim it.¹

Recording Deadline and Service on the Owner

Record the completed, acknowledged document with the auditor of the county where the property sits. The deadline is 90 days after the claimant last furnished labor, services, materials, or equipment to the project — measured from the last day of actual work or delivery, not from the day payment came due.¹

The base state recording fee is $5 for the first page and $1 for each additional page, but counties add surcharges that vary, so confirm the total with the local auditor before filing.⁷

After recording, the claimant has 14 days to serve a copy of the recorded lien on the owner or reputed owner by certified or registered mail or by personal service.¹ This is not a formality. Missing the 14-day window exposes the claim to challenge.

Enforcement: The Eight-Month Deadline

A recorded lien expires after eight calendar months unless the claimant files a foreclosure lawsuit in the superior court of the county where the property sits.² No court will extend this deadline. If the lien recites that credit was extended and states the credit terms, the eight months runs from the end of the credit period rather than the recording date.⁴

Filing alone isn’t enough. The claimant must serve the owner with the summons and complaint within 90 days after the foreclosure action is filed, which can occur after the eight-month deadline as long as it happens inside that 90-day service window.⁴ Once suit is filed, the case must be pushed to judgment within two years or the court may dismiss it, which cancels the lien.²

A mandatory arbitration clause in the underlying contract does not excuse the statutory foreclosure deadline. Arbitrators cannot foreclose a lien; only a court can. The standard practice is to file the foreclosure action in court within the eight-month window to preserve the lien, arbitrate the contract dispute, and then return to court to enforce the award through the foreclosure proceeding.

Priority Against Mortgages

Priority decides who gets paid first when the property sells or when multiple creditors compete for the same equity. Washington uses a relation-back rule: a mechanics lien is senior to any mortgage, deed of trust, or other encumbrance recorded after (or unrecorded at) the time the claimant first delivered labor, services, or materials.⁸

Construction lenders get a large carve-out. Under RCW 60.04.226, a recorded mortgage or deed of trust generally takes priority over later liens and encumbrances to the full extent of amounts it secures, except as provided in RCW 60.04.061 and 60.04.221.⁴ In practice, a construction loan recorded before work begins usually outranks a mechanics lien, while a lien for work started before the mortgage was recorded can outrank the mortgage. The exact timeline of first work versus loan recording controls the outcome.

How Owners Can Fight Back

Property owners are not stuck with an inflated or baseless claim. Under RCW 60.04.081, an owner (or an affected contractor, subcontractor, or lender) can file a motion in superior court ordering the claimant to appear within six to fifteen days and show cause why the lien should not be released or reduced.⁴

If the claimant fails to appear, the lien is released with prejudice and the claimant pays the applicant’s costs and attorney fees. If the claimant appears but the court finds the lien frivolous or clearly excessive, the court releases or reduces it and awards costs and fees to the applicant. But if the court finds the lien valid and reasonable, the party who brought the challenge pays the claimant’s costs and fees.⁴ Neither side plays this move for free.

Clearing a Lien With a Bond

An owner who needs to sell or refinance while a lien is pending can dissolve it by recording a surety bond under RCW 60.04.161. Once a qualifying bond is filed, the lien is dissolved and the title clears.⁴ The claimant’s rights shift to the bond; recovery is pursued against the surety instead of through a forced sale.

Lien Waivers Before Payment

On most projects, owners and lenders require lien waivers as a condition of payment. Confusing the two main types causes real losses.

A conditional waiver takes effect only if payment actually clears. If the check bounces or funds never arrive, the waiver is void and lien rights survive. An unconditional waiver takes effect the moment it’s signed, whether or not payment clears. Each comes in a progress-payment version (covering only the current draw) and a final-payment version (releasing all lien rights for the entire project). The common disaster is signing an unconditional waiver before confirming funds have cleared the bank. After that signature, the lien right is gone even if the payment fails.

If the Owner Files Bankruptcy

When the property owner files bankruptcy, the automatic stay under 11 U.S.C. § 362(a) generally blocks acts to create, perfect, or enforce a lien against estate property. A narrow exception in Section 362(b)(3) allows acts to perfect or maintain an interest when the trustee’s avoidance powers are subject to such perfection under Section 546(b).⁹ Section 546(b) recognizes state laws that let perfection relate back and bind earlier interests.¹⁰ Washington’s mechanics lien statute is such a law, so a claimant may still be able to record inside the state’s window even after a bankruptcy filing. This corner of the process is a state-federal tangle where mistakes cost the lien permanently, and it warrants a bankruptcy attorney before you act.
