Mechanic's Lien Deadlines & Notice Requirements in Washington
At a glance
| Governing law | RCW Title 60, ch. 60.04 (Mechanics' and Materialmen's Liens); a single-chapter statutory lien law, substantially rewritten by 1991 c 281, not tied to any uniform act |
|---|---|
| Who can claim a lien | Anyone furnishing labor, professional services, materials, or equipment for an improvement, at the owner's or their agent's instance (RCW 60.04.021); a contractor/subcontractor only counts as the owner's lien-establishing "construction agent" if registered under ch. 18.27 or licensed under ch. 19.28 (RCW 60.04.041) |
| Preliminary notice | A written notice of the right to claim a lien is required of everyone except those contracting directly with the owner, laborers, and subs contracting directly with the prime; it can be sent anytime but only protects work from 60 days before it's sent (10 days for new single-family residential construction) (RCW 60.04.031) |
| Deadline to file the lien | Flat 90 days after the claimant personally ceases furnishing labor, services, materials, or equipment — no split by claimant tier (RCW 60.04.091); each unit in a multi-unit residential project gets its own 90-day clock (RCW 60.04.101) |
| Notice of completion effect | None — Washington's chapter has no owner-recorded notice of completion or cessation; the 90-day filing clock always runs from the individual claimant's own last date of furnishing |
| Serving the lien on the owner | The claimant must mail (certified/registered) or personally serve a copy of the recorded lien on the owner within 14 days of recording; missing that deadline only forfeits the claimant's right to attorneys' fees and costs, it does not invalidate the lien (RCW 60.04.091) |
| Deadline to sue to foreclose | Sue within 8 calendar months after recording, or after stated credit expires, and serve the owner within 90 days of filing; a court may dismiss an action not brought to judgment within 2 years (§ 60.04.141). |
| Homestead/residential extras | Existing owner-occupied home repairs/remodels: a claimant dealing directly with the owner-occupier needs no notice and gets a lien for the full contract amount; anyone else must give notice and their lien is capped to what the owner still owed the prime contractor when the notice was received (RCW 60.04.031(3)) |
Requirements one by one
Who can claim
RCW 60.04.021 grants a lien for labor, professional services, materials, or equipment furnished for an improvement at the instance of the owner or an agent. RCW 60.04.041 makes a contractor or subcontractor who must register or obtain a license the owner's construction agent for lien purposes only if registered or licensed. It also preserves a claimant's rights despite a remote contractor's registration loss when that contractor is outside the claimant's immediate contractual chain.
Preliminary notice
Under RCW 60.04.031(1), notice can be given at any time, but protects only professional services, materials, or equipment supplied during the preceding 60 days and afterward. For new single-family construction, the lookback is ten days. Subsection (2) exempts direct owner contractors, labor-only claimants, and subcontractors contracting directly with the prime contractor, subject to the home-repair rule below.
Deadline to file the lien
RCW 60.04.091 requires recording within 90 days after the claimant stops furnishing labor, services, materials, or equipment, or after employee benefit contributions were last due. RCW 60.04.101 measures the period separately for each residential unit in a development.
Serving the lien on the owner
RCW 60.04.091 requires a copy of the recorded claim to reach the owner by certified or registered mail or personal service within fourteen days after recording. Missing this step forfeits a right to attorney fees and costs against the owner; the same provision does not say the lien itself expires.
Deadline to sue to foreclose
RCW 60.04.141 requires filing an enforcement action within eight calendar months after recording and serving the owner within 90 days after filing. If credit was given and its terms stated in the lien, the eight months run from expiration of that credit. A court may dismiss for want of prosecution if no judgment is reached within two years after suit begins.
Homestead/residential extras
For repair or remodel of an existing owner-occupied single-family home, RCW 60.04.031(3) exempts a direct owner contractor from notice. A claimant without a direct owner contract must give notice, and its lien can be satisfied only from the amount the owner had not yet paid the prime contractor when notice arrived.
What trips people up
The 90-day recording period does not recover materials left outside the earlier preliminary-notice lookback. On new single-family construction, a notice mailed after the first ten days can already leave early supplies unprotected under RCW 60.04.031(1).
Common questions
Must the recorded lien be signed and acknowledged? Yes. RCW 60.04.091(2) requires the claimant or an authorized person to sign, affirm the statement under penalty of perjury, and acknowledge it.
Does an owner's bankruptcy petition pause the foreclosure period? RCW 60.04.141 tolls the statutory limitation period when an owner of the liened property files a petition under Title Eleven of the United States Code.
