# Washington Notice of Right to Claim Lien: Requirements & Deadlines

Washington subcontractors, sub-subcontractors, and material suppliers who do not have a direct contract with the property owner must serve a Notice of Right to Claim Lien within 10 days of first furnishing labor, materials, or equipment to the project, under [RCW 60.04.031](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.031). The notice must be delivered to the owner and the prime contractor by personal service or by certified or registered mail with return receipt requested. Missing this deadline does not bar lien rights entirely — but it limits protection to labor and materials furnished after serving a late notice. Failing to serve the notice at all is a complete bar to mechanics lien rights on private works for parties without a direct owner contract.

## Who Is Required to Serve a Washington Notice of Right to Claim Lien?

Any party without a direct contract with the property owner is required to serve a Notice of Right to Claim Lien in Washington. This includes subcontractors, sub-subcontractors, material suppliers, equipment lessors, and design professionals hired by someone other than the owner.

General contractors who have a direct contract with the property owner are exempt from the notice requirement — their lien rights attach automatically. However, if you are a second-tier sub working under a general contractor or a supplier selling to a subcontractor, you have no automatic lien protection. The notice is your mechanism for preserving rights against the property and protecting yourself if the GC or upper-tier sub fails to pay.

Laborers hired directly by a subcontractor also have lien rights and must follow the same notice rules. If you supply both labor and materials under a single subcontract, one notice covers the full scope.

## What Is the Deadline for Serving the Notice in Washington?

The deadline is 10 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). "First furnishing" is the date your crew mobilizes, your materials are delivered to the jobsite, or your equipment arrives — whichever comes first.

If you miss the 10-day window, you can still serve a late notice. But under [RCW 60.04.031](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.031)(2), a late notice only protects work performed and materials furnished within 10 days before the date of service and all labor, materials, and equipment furnished after that date. Work performed before that 10-day lookback period is unprotected. On a long project, that exposure can be substantial.

This is not a forgiving statute. If you are 30 days into a project and have not served the notice, you have already lost lien rights on roughly the first 20 days of work. Serve the notice immediately — do not wait until you sense a payment problem.

## What Information Must the Notice Include?

A valid Washington Notice of Right to Claim Lien under [RCW 60.04.031](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.031) must contain the following information:

- **Name and address of the claimant** (the subcontractor or supplier serving the notice)
- **Name of the person who contracted for the labor, materials, or equipment** (typically the GC or upper-tier sub)
- **Description of the labor, materials, or equipment furnished or to be furnished**
- **Description of the property** sufficient to identify it (street address or legal description)
- **Name of the owner or reputed owner** of the property

Washington state prescribes specific statutory language that must appear on the face of the notice. [RCW 60.04.031](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.031)(1) mandates verbatim warning language informing the owner that a lien may be claimed against the property. Using a form that omits or paraphrases this language can invalidate the notice. The statute's required warning reads, in part, that a lien has been or may be claimed against the owner's property and that the owner may protect themselves by requiring the contractor to provide lien releases.

Do not draft this from memory. Use an attorney-reviewed template that tracks the current statutory form.

## How Must the Notice Be Served?

Under [RCW 60.04.031](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.031), the notice must be served on both the property owner and the prime contractor. Service is valid by:

1. **Personal delivery** to the owner or prime contractor
2. **Certified or registered mail with return receipt requested**, addressed to the last known address of the recipient

Washington courts have held that actual receipt is not always required — proper mailing to the correct address satisfies the service requirement. However, you need documentation proving you mailed the notice. A Certificate of Mailing from USPS is your evidence. If the dispute ever goes to court, your ability to prove timely service depends on that paper trail.

USPS Certified Mail costs $4.85 as the base service fee in 2026, plus standard First-Class postage (per USPS Notice 123). Adding an electronic Return Receipt adds $2.46; a physical green card adds $4.10. These are small costs compared to the contract value at risk.

Send separate certified mail to the property owner and the GC. One envelope addressed to both is not proper dual service.

## What Happens to Your Lien Rights If You Don't Serve the Notice?

If you have no direct contract with the property owner and you fail to serve any notice, you lose your right to file a mechanics lien in Washington. Period. [RCW 60.04.031](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.031) makes notice a prerequisite — not a formality — for non-owner-contract claimants on private works.

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. In that environment, a mechanics lien is one of the only reliable tools a subcontractor has to force payment. Losing lien rights is not a technicality — it means you are left pursuing a breach of contract claim against a subcontractor or GC who may be insolvent, with no recourse against the property itself.

The math is straightforward: a single notice filing costs $24.99 through LienFlash. If that notice preserves lien rights on a $15,000 subcontract that would otherwise go unpaid, the return on that filing exceeds 60,000% (LienFlash pricing applied to typical subcontract values, BLS data).

## Does the Notice Requirement Apply on Public Projects?

No. The Washington Notice of Right to Claim Lien under RCW 60.04 applies only to private construction projects. Public projects — work performed for state agencies, counties, cities, or other government entities — are governed by a different statute and a different protection mechanism.

On public works in Washington, subcontractors and suppliers protect their payment rights through a claim against the public works retainage bond or the retainage fund, governed by RCW 60.28. There is no mechanics lien right against public property, and the [RCW 60.04.031](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.031) notice plays no role in public project claims.

If you work on both private and public jobs, be clear about which rules apply to which project before you start. Confusing the two can leave you without any protection on either.

## How Does Washington's Requirement Compare to Neighboring States?

Washington's 10-day deadline is significantly tighter than most states. Oregon requires a preliminary notice within 8 days for suppliers but allows suppliers to send notice up to certain project completion thresholds under [ORS 87.021](https://oregon.public.law/statutes/ors_87.021). California requires a 20-day preliminary notice under [Cal. Civ. Code § 8200](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV&sectionNum=8200.). Arizona's deadline is 20 days under [A.R.S. § 33-992.01](https://www.azleg.gov/ars/33/00992-01.htm).

The practical implication: if your crews or trucks cross state lines — or if you bid multi-state work — you cannot apply the same notice timeline to every project. Washington's 10-day rule demands that you trigger the notice process the same week you mobilize, not two weeks later.

## What Is the Deadline to File the Mechanics Lien Itself?

The Notice of Right to Claim Lien is not the lien — it is the prerequisite notice that preserves your right to file a lien later. The mechanics lien itself must be filed in the county where the property is located within 90 days of the last day labor or materials were furnished, under [RCW 60.04.091](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.091).

After filing the lien, you must serve a copy on the owner within 14 days of recording. After the lien is recorded, you have 8 months to file a lawsuit to foreclose the lien, or it expires ([RCW 60.04.141](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.141)).

The timeline, compressed:

- **Day 1-10:** Serve Notice of Right to Claim Lien
- **Within 90 days of last furnishing:** Record mechanics lien with county auditor
- **Within 14 days of recording:** Serve copy of lien on property owner
- **Within 8 months of recording:** File foreclosure lawsuit or lien expires

Miss any of these deadlines and you lose rights at that stage. The notice is the first gate. Do not skip it.

## Frequently Asked Questions

### Does a general contractor need to serve a Washington Notice of Right to Claim Lien?

No. General contractors with a direct contract with the property owner are exempt from the [RCW 60.04.031](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.031) notice requirement. Their lien rights attach automatically by virtue of the direct owner contract. The notice requirement applies to subcontractors, sub-subcontractors, suppliers, and equipment lessors who contract with someone other than the property owner.

### What if I serve the notice late — do I lose all lien rights?

Not entirely. Under [RCW 60.04.031](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.031)(2), a late notice protects labor and materials furnished within 10 days before the date of service and all work performed after service. Work furnished more than 10 days before the late notice was served is unprotected. The earlier you serve — even if late — the more contract value you preserve.

### Can one notice cover the entire project duration?

Yes. A single Notice of Right to Claim Lien served within 10 days of first furnishing covers all subsequent labor and materials furnished on that project. You do not need to refile each time you deliver additional materials or continue work. However, if you are working on a completely separate project at the same address under a new contract, that new scope requires a new notice.

### Does the notice need to be notarized?

No. Washington's [RCW 60.04.031](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.031) does not require the Notice of Right to Claim Lien to be notarized. It does require the statutory warning language and proper service on both the owner and the prime contractor. The mechanics lien itself (filed later, if needed) must be signed under oath, but the preliminary notice does not carry that requirement.

### What address do I use to mail the notice to the property owner?

Use the last known address of the owner. If you do not have a direct relationship with the owner, check the county assessor's records — property ownership and mailing address are public information and available online in most Washington counties. If you are working through a GC, they are typically required under [RCW 60.04.230](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.230) to provide project ownership information upon request.

### Does the 10-day clock start when I sign the contract or when I first furnish?

The clock starts when you first furnish labor, materials, or equipment to the project — not when you sign the contract, not when the contract is executed, not when permits are pulled. The trigger is your first physical act of performance on the job. For a materials supplier, that is the first delivery. For a subcontractor, that is the first day your crew works on-site.

### Is the Notice of Right to Claim Lien required on residential projects?

Yes. Washington's lien notice requirements under RCW 60.04 apply to both commercial and residential private construction projects. There is no residential exemption for the preliminary notice. Note, however, that residential projects may have additional disclosure requirements under [RCW 60.04.230](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.230) that the GC must provide to the owner — but those are separate from the subcontractor's obligation to serve the notice.

### Can I still get paid if I miss the notice deadline entirely?

You can still pursue payment through a breach of contract lawsuit against the party who hired you. Missing the notice eliminates your mechanics lien rights against the property — it does not erase the underlying contract debt. However, a breach of contract claim against a subcontractor or GC who has become insolvent is far less valuable than a lien against the property itself. The notice exists precisely because contract claims alone often do not result in payment.
