Washington Notice of Right to Claim Lien Deadline Calculator
Washington has the most nuanced lien notice deadline of any state — TWO rules depending on project type. Standard construction (commercial, multi-family, remodels, additions) follows the 60-calendar-day rule under RCW 60.04.031. New construction of a single-family residence follows a much shorter 10-day rule under RCW 60.04.031(2)(a). Washington applies a partial-loss rule — late filing still preserves rights for the lookback window plus all future work. Choose your project type below to get your exact deadline.
Two Rules. Pick The Right One.
The 10-day rule applies ONLY to new construction of single-family residences. If you are working on a remodel, addition, multi-family, or commercial project, you have 60 days. Picking the wrong rule means missing the actual deadline. Confirm your project type before relying on the result.
Calculate Your Deadline
How the Two Washington Rules Work
RCW 60.04.031 is the primary statute. It creates two parallel deadlines based on project type:
Applies to commercial construction, multi-family residential, remodels, additions, infrastructure, and any project that is not new single-family residential.
Applies ONLY to new construction of a single-family residential dwelling. Smaller window because Washington treats residential homeowners as needing extra notice.
Both rules count CALENDAR days. Weekends, holidays, and weather days all count. If Day 10 or Day 60 falls on a Saturday, the deadline is still that Saturday.
When Does the 10-Day Rule Apply
The 10-day rule is the most commonly misapplied lien notice deadline in Washington. Two requirements must BOTH be true:
- The project is creating a NEW dwelling from the ground up (not a remodel, not an addition)
- The dwelling is a single-family residence (not a duplex, triplex, or apartment building)
Falls under the 60-day rule (NOT the 10-day rule):
- Kitchen remodel on existing single-family home
- New garage addition on existing single-family home
- New duplex or triplex construction
- New apartment building (multi-family)
- Any commercial construction
The Washington Partial-Loss Rule
Washington applies a partial-loss rule like California, Arizona, and Nevada — late preliminary notice does not eliminate all lien rights. Filing late preserves lien rights for:
- All work performed in the X days IMMEDIATELY BEFORE the date the notice is served (where X is your rule's window — 60 or 10)
- All work performed AFTER the notice is served
What you lose: lien rights for work performed MORE than X days before the service date.
Practical implication for the 10-day rule: The shorter window means partial-loss happens much faster. Filing on Day 15 of a new single-family residential project means you've already lost 5 days of work. The same delay on a commercial project (using the 60-day rule) loses nothing — you're still within the safe window.
Slow payments cost the U.S. construction industry an estimated $280 billion in 2024, according to Rabbet's 2024 Construction Payments Report. Filing today always preserves more leverage than not filing at all — regardless of which Washington rule applies.
Who Must File a Washington Notice
Per RCW 60.04.031, the following parties must serve the Notice of Right to Claim Lien:
- Subcontractors who contract with a prime contractor
- Sub-subcontractors below the first-tier subcontractor
- Material suppliers who furnish materials to any party below the owner
- Equipment lessors who lease equipment to a contractor or subcontractor
- Design professionals who furnish professional services to the project
Direct contractors with the owner are typically exempt. They have privity with the owner and do not need the notice to preserve their lien rights.

Frequently Asked Questions
What is the Washington Notice of Right to Claim Lien deadline?
Washington has two deadlines depending on the project type. Standard projects (commercial, multi-family residential, remodels, additions, infrastructure) follow a 60-calendar-day deadline under RCW 60.04.031. New single-family residential construction follows a much shorter 10-calendar-day deadline under RCW 60.04.031(2)(a). The clock starts on the day of first furnishing labor or materials.
When does the 10-day rule apply in Washington?
The 10-day rule under RCW 60.04.031(2)(a) applies ONLY to new construction of a single-family residence. It does NOT apply to remodels of existing residences, additions to existing residences, multi-family residential, or commercial construction. If you are working on a brand-new house being built from the ground up, you are subject to the 10-day window. If you are working on anything else, you have 60 days.
What happens if you file the Washington notice late?
Washington applies a partial-loss rule similar to California, Arizona, and Nevada. Late filing still preserves lien rights for work performed in the 60 days (or 10 days, depending on project type) before service date plus all work going forward. You lose lien rights only for work performed MORE than 60 days (or 10 days) before service. Filing today always preserves more contract value than not filing at all.
How do I know if my project counts as "new single-family residential"?
The 10-day rule applies when (1) the project is creating a NEW single-family residential dwelling from the ground up, AND (2) the building is intended for use as a single-family residence. Remodels of existing single-family homes follow the 60-day rule. Additions to existing single-family homes follow the 60-day rule. New duplexes, triplexes, or multi-family construction follow the 60-day rule. When in doubt, consult a Washington construction attorney before filing.
Who must file a Washington Notice of Right to Claim Lien?
Per RCW 60.04.031, any potential lien claimant who furnishes labor, materials, equipment, or professional services to a construction project and is not in direct privity with the property owner must serve the notice. This includes subcontractors, sub-subcontractors, material suppliers, equipment lessors, and design professionals. Direct contractors with the owner are typically exempt from the notice requirement.
Who must receive the Washington notice?
Per RCW 60.04.031, the notice must be served on the owner or reputed owner of the property, the prime contractor (if the claimant is not the prime contractor), and any lender providing construction financing. Failure to serve any required recipient can invalidate lien rights against that party.
How must the Washington notice be served?
Per RCW 60.04.031, valid service methods are: (1) certified or registered mail with return receipt requested, (2) personal delivery to the recipient, or (3) by leaving with the recipient or at the recipient's place of business. LienFlash uses USPS Certified Mail with Return Receipt as standard practice for ironclad proof of service.
