Arizona Mechanics Lien Law: Deadlines, Notices & Filing Guide
Arizona lien deadlines come from A.R.S. §§ 33-993 & 33-1003 for private work and A.R.S. §§ 34-221 to 34-227 for public projects under the state's Little Miller Act. Timing hinges on completion, or an owner-filed Notice of Completion, making early tracking critical.
Arizona mechanics lien deadlines at a glance
Arizona limits lien rights to parties in direct contract with the general contractor or a first-tier subcontractor, meaning more remote parties such as supplier-to-supplier or supplier-to-sub-subcontractor relationships fall outside lien protection. A timely Preliminary 20-Day Notice is also a prerequisite to preserving lien rights for those who do qualify.
A claimant generally must record its lien within 120 days after completion of the project if no Notice of Completion has been filed, under A.R.S. §§ 33-993 & 33-1003. If the owner records a Notice of Completion, that window shortens to 60 days from the date of that filing, so every claimant should watch for it.
Foreclosure must be filed within six months after the lien is recorded; this deadline is treated as jurisdictional and cannot be extended.
On Arizona public projects, bond rights are similarly limited to parties in direct contract with the general contractor or a first-tier subcontractor, so claimants further down the contracting chain do not have a bond remedy.

Who can file a mechanics lien in Arizona?
Arizona lien rights are available to general contractors, subcontractors, sub-subcontractors, material suppliers, and qualifying design professionals who furnished labor, materials, or services to the improvement, though remoteness in the contracting chain can limit who ultimately qualifies.
Overview of Arizona lien practice
Arizona's lien scheme is notable for tying the standard recording deadline to project completion rather than the claimant's own last day on site, giving claimants 120 days after completion, or only 60 days if the owner records a Notice of Completion. Because that filing can compress the timeline sharply, contractors and suppliers should monitor the county recorder for a Notice of Completion throughout the job. A valid Preliminary 20-Day Notice is a prerequisite to lien rights, and Arizona additionally limits eligibility to parties in direct contract with the general contractor or a first-tier subcontractor, cutting off more remote suppliers and sub-subcontractors from lien and bond remedies alike. Once recorded, the lien must be enforced by a foreclosure suit within six months, a deadline the courts treat as jurisdictional with no room for tolling. As in every state, federal property cannot be reached by an Arizona mechanics lien, so a bond claim is the only available route there. Confirming the correct owner of record and county before recording remains basic due diligence.
Common pitfalls on Arizona projects
Serve the owner after recording
A copy of the recorded lien must be served on the owner within five days of recording under A.R.S. § 33-993(F).
Preliminary notice is a prerequisite
Lien rights depend on having served a timely Preliminary 20-Day Notice; skipping it forfeits the claim.
Notice of Completion shortens the clock
If the owner records a Notice of Completion, every claimant's recording deadline compresses to 60 days from that filing.
Six-month suit deadline cannot be tolled
Missing the six-month foreclosure deadline extinguishes the lien outright, since courts treat it as jurisdictional.
