Washington subcontractors, material suppliers, and equipment lessors who do not have a direct contract with the property owner must serve a Notice of Right to Claim Lien within 60 days of first furnishing labor, materials, or equipment to a private construction project, under RCW 60.04.031. The notice must be served on the owner and the prime contractor via personal delivery or certified mail with return receipt. Missing the 60-day window does not eliminate lien rights entirely — it limits protection to work performed within 60 days before the notice was served. Failing to serve the notice at all when required is a complete bar to mechanics lien rights on private works in Washington State.
Who Must Send a Pre-Lien Notice in Washington State?
Any subcontractor, material supplier, or equipment lessor without a direct contract with the property owner must send a Notice of Right to Claim Lien before filing a mechanics lien on a private project. Under RCW 60.04.031, this requirement applies regardless of your trade — electrician, plumber, roofer, HVAC, drywall, painter, concrete sub, or any other specialty contractor two or more tiers removed from the owner.
General contractors with a direct contract with the owner are exempt from the preliminary notice requirement. Labor unions filing on behalf of workers and certain materialmen have specific provisions, but the default rule for any first- or second-tier subcontractor is: no notice, no lien rights.
If you are a material supplier to a material supplier (third tier or lower), Washington's lien statute still requires a notice, but your lien rights have additional limitations. When in doubt about your tier position, serve the notice. The cost of sending it is trivial compared to the cost of losing your lien rights on a $40,000 scope of work.
What Is the Washington State Preliminary Notice Deadline for Subcontractors?
The deadline is 60 days from the date you first furnish labor, materials, or equipment to the project — not 60 days from the last day of work, not 60 days from invoice due date. RCW 60.04.031 is explicit: the clock starts on the first day you show up or deliver materials.
This is one of the most common mistakes subs make in Washington. A crew that mobilizes on Day 1 and wraps up 90 days later has until Day 60 to serve the notice. If they wait until the job ends to think about paperwork, they have already missed the window by 30 days.
Late service does not wipe out all lien protection. If you serve the notice on Day 70, your lien rights cover labor and materials furnished during the 60-day period immediately before that service date. Work performed in the first 10 days is unprotected. The later you wait, the more exposure you carry.
The practical rule: serve the notice within the first week of work. Day 1 is ideal. Waiting until Day 55 to "see how the job goes" is a gamble that costs nothing to avoid.
What Are the Washington State Pre-Lien Notice Form Requirements?
Washington's pre-lien notice must contain specific statutory language to be valid. Under RCW 60.04.031(2), the notice must include:
- The name and address of the claimant (your business name and mailing address)
- The name and address of the person who contracted for the labor, materials, or equipment (your direct customer — the GC or upper-tier sub)
- A description of the labor, materials, or equipment provided (what you're doing on the job)
- The name of the owner or reputed owner of the property
- The common street address or legal description of the property
- The following statutory warning language, which must appear verbatim on the notice:
"NOTICE TO PROPERTY OWNER: If the person named above fails to pay the person giving you this notice for labor, materials, equipment, or taxes owed by the person named above in connection with your project, a lien may be placed on your property. A lien is a legal claim against your property. Liens must be satisfied before your property can be sold. To ensure that you are fully protected, you may withhold a sufficient amount from the prime contractor to ensure that the person giving you this notice is paid."
Missing required elements or using a non-compliant form are grounds for the notice to be challenged. Using an attorney-reviewed, state-specific template eliminates that risk.

How Do You Send a Preliminary Notice in Washington State?
Washington law accepts two delivery methods for a preliminary notice under RCW 60.04.031(3):
- Personal delivery — physically handing the notice to the owner and prime contractor (or their authorized agents)
- Certified mail with return receipt requested — mailed to the last known address of the owner and prime contractor
First-class mail alone is not sufficient for Washington preliminary notices. You need the certified mail tracking and return receipt to prove service if the notice is challenged in a lien dispute. Keep every receipt, tracking confirmation, and green card (or electronic return receipt) as part of your project records.
Serve the notice on both the property owner and the prime contractor. Serving only one of the two parties is not compliant with RCW 60.04.031.
USPS Certified Mail currently costs $4.85 as the base service fee plus standard First-Class postage, with electronic Return Receipt adding $2.46 (per USPS Notice 123, effective 2026). For two certified mailings — one to the owner, one to the GC — you are looking at roughly $15–$20 in postage. That $15–$20 is protecting whatever your contract value is on that job.
According to Rabbet's 2024 Construction Payments Report, 82% of contractors face payment waits of over 30 days, up from 49% just two years earlier. A served and documented preliminary notice is one of the few concrete tools a sub has to apply real legal pressure on a slow-paying GC or owner.
Does Washington State Require Pre-Lien Notices on Public Projects?
No. Washington's preliminary notice requirement under RCW 60.04.031 applies to private construction projects only. Public works projects — government buildings, school districts, municipalities, state agencies — are governed by a completely different framework under Washington's public works bond statutes (RCW 39.08).
On public projects in Washington, there is no real property to lien. The protection mechanism is a Payment Bond posted by the prime contractor, and the process for making a claim against that bond has its own notice and deadline requirements under RCW 39.08.030. If you are working on a public job, research the payment bond claim process separately — it is not the same as the private preliminary notice system.
For private projects only: single-family residential, multi-family, commercial, and industrial construction all fall under RCW 60.04's lien and preliminary notice framework.
What Happens If You Miss the Pre-Lien Notice Deadline in Washington?
Missing the 60-day deadline in Washington does not automatically kill all of your lien rights, but it will cost you money. Here is exactly what happens:
If you serve late (after 60 days): Your mechanics lien can only cover labor and materials furnished within the 60 days immediately before you served the notice. Work performed outside that window is unprotected. On a long job where most of your contract value was earned in the first two months, a late notice could gut your entire lien claim.
If you never serve the notice: You cannot file a valid mechanics lien on a private project in Washington. Without lien rights, your collection options drop to pursuing a civil lawsuit on breach of contract, which takes longer, costs more, and gives you no leverage over the property itself.
If the job ends and you realize you missed it: Serve the notice immediately. Partial protection is better than none. Then call your attorney to assess exactly what portion of your contract value falls within the protected 60-day lookback period.
The math here is not subtle. According to Rabbet's 2024 Construction Payments Report, slow payments cost the U.S. construction industry an estimated $280 billion in 2024, adding roughly 14% to total construction spending. Subs absorb a disproportionate share of that pain. A preliminary notice is one of the cheapest insurance policies in construction.
How to Track and Manage Washington Preliminary Notice Deadlines Across Multiple Jobs
If you run one or two jobs at a time, a calendar reminder set for Day 1 of each project works. If you are running five, ten, or twenty active jobs simultaneously, manual tracking creates real exposure.
The 60-day clock starts independently for every project. Miss it on one job because a foreman mobilized early without notifying the office, and you are chasing an uncollectable $30,000 invoice with no legal leverage.
Contractors who manage notice deadlines manually typically rely on:
- A project start log updated the day work begins
- Calendar alerts set for Day 45 (warning) and Day 55 (hard deadline)
- A designated person in the office responsible for confirming notice was served and filed
Automating this process removes the human error. When the deadline is tracked by software that triggers notices automatically, the 60-day window becomes a non-issue.
Frequently Asked Questions
Does a sole proprietor electrician or plumber need to send a pre-lien notice in Washington?
Yes. The requirement under RCW 60.04.031 applies to any subcontractor without a direct contract with the property owner, regardless of business size. A one-person electrical sub working under a GC must serve the notice within 60 days of first furnishing work. Business size is not a factor in the statute.
Can I send the Washington preliminary notice by regular first-class mail?
No. RCW 60.04.031(3) requires either personal delivery or certified mail with return receipt requested. First-class mail alone does not satisfy the statutory delivery requirement and will not hold up if service is disputed in a lien enforcement action.
What address do I use if I cannot find the property owner?
Use the last known address of the owner. Washington courts look at whether you made a good-faith effort to identify and serve the owner. Check the county assessor's records for the registered property owner and document your search. Serve to the best address available and retain proof of the mailing.
Does the Washington pre-lien notice deadline apply to a project I have been on for months with no written subcontract?
Yes. The 60-day clock runs from the date you first furnished labor or materials, regardless of whether a written contract exists. If you mobilized without a signed sub agreement, the clock was still ticking from Day 1. Assess where you are in the window and serve immediately if you are still within 60 days.
Is there a filing fee to record the Washington preliminary notice with the county?
No. The preliminary notice under RCW 60.04.031 is served directly on the owner and prime contractor — it is not recorded with the county. There is no county recording fee for the preliminary notice itself. The mechanics lien (filed later, if needed) is recorded with the county and carries a recording fee.
If I send the notice on Day 58, does it protect my full contract value?
No. A notice served on Day 58 protects only labor and materials furnished within the 60 days before service — meaning work from Day 1 through roughly Day 58, minus any work performed in the first two days of the project outside that rolling 60-day window. The earlier you serve the notice, the more of your contract value is protected. Serving on Day 1 protects everything.
Do I need to re-send a preliminary notice if the project owner changes mid-project?
Yes, you should. If ownership of the property transfers and you have not yet been paid, serve a new notice on the new owner to preserve your lien rights against them. Relying solely on notice served to a prior owner creates legal uncertainty. Serve again and document the new owner's identity from county assessor records.
Does a Washington preliminary notice expire?
The notice itself does not expire, but your mechanics lien rights do. Under RCW 60.04.141, a mechanics lien in Washington must be recorded within 90 days after the last date you furnished labor, materials, or equipment to the project. Serving the preliminary notice on time is only step one — you still must file the actual lien within the 90-day window if you are not paid.
