Arizona: Mechanic's Lien Deadlines & Notice Requirements

The short answer

Arizona runs an unusually strict version of the standard notify-file-serve-sue
sequence. Almost every claimant — the only exception is a person performing
actual labor for wages — must serve a preliminary 20-day notice within 20 days
of first showing up on the job, and the statute calls that notice "a necessary
prerequisite to the validity of any claim of lien," not just a step that
narrows the lien if missed. The lien itself must be recorded within 120 days
after the whole project is completed, cut to 60 days if the owner records a
notice of completion. Two licensing gates sit on top of that sequence: an
unlicensed contractor and an unregistered design professional both lose lien
rights entirely, regardless of how well they did the work. Once recorded, the
foreclosure suit deadline is a tight 6 months, and a residence already
occupied by its owner before work began can't be liened at all unless the
claimant dealt directly with that owner.

Requirements one by one

Governing law

Arizona's mechanic's lien law sits in Arizona Revised Statutes Title 33,
Chapter 7, Article 6, "Liens on Property" (§§ 33-981 to 33-1008). It is a
traditional single-article statutory lien scheme, not built on any national
uniform act, and has been amended piecemeal over the decades rather than
recast wholesale the way California's law was.

Who can claim

A.R.S. § 33-981(A) gives a lien to "every person who labors or furnishes
professional services, materials, machinery, fixtures or tools in the
construction, alteration or repair of any building, or other structure or
improvement." Two licensing gates sit directly beneath that broad grant,
though: subsection (C) says a person "required to be licensed as a
contractor but who does not hold a valid license... shall not have the lien
rights provided for in this section," and subsection (E) applies the same
bar to a design professional without "a valid certificate of registration."
Subsection (F) further requires a design professional to have an agreement
with the owner, or with an architect, engineer, or contractor who has an
agreement with the owner, before their lien rights are enforceable at all.

Preliminary notice

A.R.S. § 33-992.01(B) requires "every person" who furnishes labor,
professional services, materials, machinery, fixtures, or tools to serve a
written preliminary 20-day notice on the owner, the original contractor, the
construction lender (if any), and whoever the claimant contracted with —
"as a necessary prerequisite to the validity of any claim of lien." The only
exception is "a person performing actual labor for wages." Subsection (C)
sets the deadline at "not later than twenty days after the claimant has
first furnished" work to the jobsite. A late notice under subsection (E)
doesn't kill lien rights outright, but it "is entitled to claim a lien only
for... labor, professional services, materials, machinery, fixtures or tools
furnished within twenty days before the service of the notice and at any
time thereafter" — everything furnished earlier falls out of the lien for
good.

Deadline to file the lien

A.R.S. § 33-993(A) gives every claimant, regardless of tier, the same "one
hundred twenty days after completion of a building, structure or
improvement" to record a notice and claim of lien with the county recorder
and then serve a copy on the owner "within a reasonable time thereafter."
Subsection (B) treats a multi-building residential project specially:
"each building is a separate work," so the 120-day clock runs separately for
each building rather than for the project as a whole.

Notice of completion effect

Arizona defines "completion" itself, and lets an owner shorten the clock by
recording a notice of it. Under § 33-993(C), completion happens at the
earliest of "thirty days after final inspection and written final
acceptance by the governmental body which issued the building permit," or
"cessation of labor for a period of sixty consecutive days" (excluding
strikes, material shortages, or an act of God). If the owner then records a
notice of completion, § 33-993(A) cuts every claimant's filing window from
120 days down to "sixty days after recordation of such notice" — a sharp
acceleration that applies across the board, not just to one claimant tier.

Serving the lien on the owner

Unlike some states, Arizona folds service on the owner into the same step as
recording. Section 33-993(A) requires the claimant to record one copy with
the county recorder "and within a reasonable time thereafter serve the
remaining copy upon the owner of the building, structure or improvement, if
he can be found within the county." The statute doesn't spell out a
consequence for a missed or late service the way it does for the
preliminary notice — the enforceability rules elsewhere in the article don't
condition the lien's validity on this particular service step the way they
do on the preliminary notice.

Deadline to sue to foreclose

A.R.S. § 33-998(A) is direct: a lien "shall not continue for a longer period
than six months after it is recorded, unless action is brought within that
period to enforce the lien and a notice of pendency of action is recorded"
in the county where the property sits. Arizona's 6-month window is on the
shorter end among the states surveyed so far, and the statute gives no
mechanism to extend it by agreement.

Homestead/residential extras

A.R.S. § 33-1002 singles out a "dwelling" (a one- or two-family residence,
including a condo unit) whose owner was already an "owner-occupant" —
someone who held title before construction started and intends to live
there at least 30 days in the following year — before work began. Subsection
(B) is categorical: "No lien provided for in this article shall be allowed
or recorded... except by a person having executed in writing a contract
directly with the owner-occupant." Anyone further down the contracting
chain — a subcontractor or supplier who never dealt with the homeowner
directly — has no lien rights against that home at all, not just a
narrower or delayed one. Subsection (C) makes this protection non-waivable:
"Any provision of an agreement made or entered into by an owner-occupant
which waives the provisions of this section is void."

What trips people up

Arizona treats the preliminary 20-day notice far more harshly than most
states in this survey: § 33-992.01(B) calls it "a necessary prerequisite to
the validity of any claim of lien," so a subcontractor or supplier who skips
it entirely — not just misses the 20-day deadline — can lose the whole lien,
not just the earliest days of work. Separately, the residential rule in
§ 33-1002 catches subcontractors and suppliers off guard on owner-occupied
jobs: unlike commercial work, there's no notice mechanism that can rescue a
lien against an already-occupied home if the claimant never contracted with
the homeowner directly — the statute simply bars the lien outright.

Common questions

Do I still need to send preliminary notice if I'm a subcontractor working
for the general contractor, not the owner?
Yes. Section 33-992.01(B) requires it of "every person" except someone
performing actual labor for wages, regardless of who they contracted with —
missing it can invalidate the entire lien, not just narrow it.

What if the owner never records a notice of completion?
Then the standard 120-day filing deadline applies, running from whichever
of the statutory "completion" triggers under § 33-993(C) happens first:
30 days after final building-permit acceptance, or 60 continuous days of no
work.

Can I lien a house that someone already lives in?
Only if you contracted directly, in writing, with that owner-occupant.
Section 33-1002(B) bars a lien against an owner-occupied dwelling by anyone
further down the chain — a sub or supplier with no direct contract with the
homeowner has no lien rights against it at all.

How much time do I have to actually sue once my lien is recorded?
Six months, per § 33-998(A) — and you must both file suit and record a
notice of pendency of action (lis pendens) within that window, or the lien
lapses with no extension available.
