Washington: Mechanic's Lien Deadlines & Notice Requirements

The short answer

Washington runs the same notify-file-serve-sue sequence as most states, but
shapes the notice step differently: instead of a hard deadline to send a
preliminary notice, the notice can go out anytime and simply looks backward,
protecting only the work done shortly before it was sent. Recording the lien
itself is a flat 90 days after the claimant's own last day of work for every
tier of claimant — there's no shorter window for subcontractors and no
owner-recorded notice of completion that speeds up the clock. Once recorded,
serving a copy on the owner within 14 days matters for collecting attorney's
fees, but a missed deadline there doesn't kill the lien the way it does in
some other states. The foreclosure suit deadline is a comparatively generous
8 months.

Requirements one by one

Governing law

Washington's mechanic's lien law is codified at RCW Title 60, Chapter 60.04,
"Mechanics' and Materialmen's Liens." The chapter was substantially rewritten
by 1991 c 281 (effective April 1, 1992), which repealed the older
19th-century lien statute and replaced it with the current numbering
(§§ 60.04.011 and up). It is a traditional single-chapter statutory lien
law, not built on any national uniform act.

Who can claim

RCW 60.04.021 gives a lien to "any person furnishing labor, professional
services, materials, or equipment for the improvement of real property...
at the instance of the owner, or the agent or construction agent of the
owner." That last phrase carries a real gate: RCW 60.04.041 says a
contractor or subcontractor is only deemed the owner's lien-establishing
"construction agent" — the legal hook that lets a sub or supplier who never
dealt with the owner directly still reach the owner's property — "only if so
registered" under the contractor registration act (ch. 18.27) or licensed
under ch. 19.28. Registered or licensed contractors, subcontractors,
material and equipment suppliers, laborers, and design professionals
(architects, engineers, surveyors) can all claim. Notably, the statute also
protects a claimant's rights even if a contractor above them in the chain
later loses their registration or license, so long as the claimant wasn't in
direct privity with that contractor.

Preliminary notice

RCW 60.04.031(1) requires most claimants to give the owner (and, in some
cases, the prime contractor) a "notice in writing of the right to claim a
lien." Unlike states with a hard pre-notice deadline, Washington's notice
"may be given at any time" — but it only protects work "supplied after the
date which is sixty days before" the notice is mailed or served. Anything
done more than 60 days before the notice goes out permanently falls outside
lien protection. New construction of a single-family residence gets a
sharply shorter look-back: only 10 days before the notice, instead of 60.
Subsection (2) exempts three groups from sending any notice at all: anyone
who contracted directly with the owner, laborers, and subcontractors who
contracted directly with the prime contractor (subject to the residential
carve-out in subsection (3)(b), below).

Deadline to file the lien

RCW 60.04.091 sets one flat rule for every claimant tier: file the notice of
claim of lien for recording "not later than ninety days after the person has
ceased to furnish labor, professional services, materials, or equipment."
Unlike states that give a direct contractor extra time or start a shorter
clock for subcontractors, Washington counts the same 90 days from each
individual claimant's own last day of work, regardless of role. For a
multi-unit residential project, RCW 60.04.101 runs a separate 90-day clock
for each "separate residential unit," starting when the claimant stops
furnishing work on that particular unit.

Notice of completion effect

Washington has no equivalent to the owner-recorded notice of completion or
cessation used in some other states to shorten the filing window. Nothing in
Chapter 60.04 lets an owner accelerate a claimant's 90-day deadline by
recording anything; the clock always runs off the claimant's own last date
of furnishing labor, services, materials, or equipment.

Serving the lien on the owner

After recording, RCW 60.04.091 requires the claimant to "give a copy of the
claim of lien to the owner or reputed owner by mailing it by certified or
registered mail or by personal service within fourteen days of the time the
claim of lien is filed for recording." The consequence of missing that
window is narrower than in some states: the statute says a late or missed
copy "results in a forfeiture of any right the claimant may have to
attorneys' fees and costs against the owner," not forfeiture of the lien
itself.

Deadline to sue to foreclose

RCW 60.04.141 gives a lien claimant 8 calendar months after recording to
commence — and have the owner served in — a foreclosure suit: the lien
doesn't bind the property "for a longer period than eight calendar months
after the claim of lien has been recorded unless an action is filed by the
lien claimant within that time... and service is made upon the owner...
within ninety days of the date of filing the action." If credit terms were
stated in the lien itself, the 8 months runs from when that credit expires
instead. Separately, if a filed foreclosure suit sits without reaching
judgment for 2 years, the court has discretion — not an automatic rule — to
dismiss it for want of prosecution.

Homestead/residential extras

RCW 60.04.031(3) creates a distinct track for "the repair, alteration, or
remodel of an existing owner-occupied single-family residence or appurtenant
garage." A claimant who contracts directly with the owner-occupier "shall
not be required to send a written notice of the right to claim a lien and
shall have a lien for the full amount due under their contract." Anyone else
on the same job must give notice to the owner-occupier, but their lien "may
only be satisfied from amounts not yet paid to the prime contractor by the
owner at the time the notice... is received" — a cap tied to what the
homeowner still owes, not the claimant's full unpaid balance. Separately,
new construction of a single-family residence gets the shortened 10-day
notice look-back described above, and multi-unit residential projects get
the per-unit filing clock under RCW 60.04.101.

What trips people up

The "backward-looking" preliminary notice is easy to misjudge: because
Washington lets the notice go out "at any time," claimants sometimes wait
weeks into a job assuming they still have time, not realizing every day that
passes is a day of unprotected work falling outside the eventual 60-day (or
10-day, for new single-family construction) look-back window. The safest
practice is still to send it as early as possible. Separately, the 14-day
post-recording service requirement is often assumed to be as fatal as it is
in other states — it isn't; RCW 60.04.091 only costs a claimant their
attorney's fees and costs for missing it, so a late copy is a real financial
setback but not, by the statute's own words, a dead lien.

Common questions

Do I have to send the preliminary notice before I start work?
No — Washington lets you send it "at any time," but the notice only protects
work performed in the 60 days (10 days for new single-family home
construction) right before you send it. Sending it early protects more of
your work.

Does a subcontractor get less time than a general contractor to file the
lien?
No. Unlike many states, Washington gives every claimant the same flat 90
days from their own last date of furnishing labor or materials, with no
separate, shorter window for subs or suppliers.

What happens if I forget to mail the owner a copy of my recorded lien?
The lien itself survives. RCW 60.04.091 only forfeits your right to recover
attorney's fees and costs from the owner if you miss the 14-day window — it
doesn't invalidate the lien the way a similar miss would in some other
states.

Is it harder to lien a home someone actually lives in?
It depends on your relationship to the owner. If you contracted directly
with the owner-occupier for a repair or remodel, you need no notice at all
and can lien the full amount owed. If you didn't, you must give notice and
your lien is capped to what the owner still owed the prime contractor when
that notice arrived.
