The notice must be served by certified mail, registered mail, or personal delivery. Missing the 20-day window does not eliminate lien rights entirely — late service limits your lien protection to work performed in the 20 days before service. Failing to serve the notice at all is a complete bar to mechanics lien rights on private works. On public projects, different bonding and notice rules apply under A.R.S. § 34-222. ## Who Is Required to Serve a Preliminary 20-Day Notice in Arizona? Any subcontractor, material supplier, equipment lessor, or labor contractor who does not have a direct contract with the property owner must serve a Preliminary 20-Day Notice to preserve lien rights on private construction projects in Arizona. Under [A.R.S. § 33-992.01](https://www.azleg.gov/ars/33/00992-01.htm), first-tier subcontractors with a direct contract with the GC, second-tier subs, specialty trades, and material suppliers are all subject to this requirement. General contractors who contract directly with the owner are not required to serve the notice. If you are an electrician, plumber, roofer, HVAC contractor, drywaller, painter, or any other trade working under a GC or upper-tier subcontractor, this notice is your legal foundation for getting paid. ## What Is the Deadline for Serving the Arizona Preliminary Notice? The deadline is within 20 days of the date you first furnish labor, materials, or equipment to the project. Under [A.R.S. § 33-992.01](https://www.azleg.gov/ars/33/00992-01.htm)(B), "first furnishing" is the trigger — not when the contract is signed, not when work is substantially complete. If you first show up on site March 1st, your preliminary notice must be served by March 21st. If you miss that window, your lien protection only covers work performed in the 20-day period preceding the date you actually serve the notice. Work done before that window is unprotected. On a large subcontract, that gap can represent tens of thousands of dollars in exposed receivables.

Under [A.R.S. § 33-992.01](https://www.azleg.gov/ars/33/00992-01.htm)(C), service must be made by one of three methods: certified mail with return receipt requested, registered mail, or personal delivery. First-class mail alone is not sufficient. The notice must be sent to three parties simultaneously: the property owner (or reputed owner), the general contractor, and the construction lender if one exists. Skipping any of these recipients creates gaps in your coverage. The owner's address can often be found on the building permit, the county assessor's records, or the recorded notice of commencement if one has been filed. Document everything — keep your certified mail receipts and tracking confirmations in the project file.

Arizona law specifies the exact content required in a Preliminary 20-Day Notice under [A.R.S. § 33-992.01](https://www.azleg.gov/ars/33/00992-01.htm)(A). The notice must include: - **Your name and address** (the claimant serving the notice) - **The name and address of the person who hired you** (your direct customer — GC or upper-tier sub) - **The name of the property owner or reputed owner** - **A description of the labor, materials, or equipment** you are or will be furnishing - **The legal description or street address** of the property - **A statutory warning statement** as prescribed by [A.R.S. § 33-992.01](https://www.azleg.gov/ars/33/00992-01.htm)(A)(6), notifying the owner that a lien may be filed if payment is not made Arizona provides a statutory form for this notice. Using a non-compliant form — or leaving out required fields — can invalidate the entire notice. Attorney-reviewed templates remove that risk. ## What Is the Deadline to File a Mechanics Lien in Arizona After a Notice Is Served? Serving the preliminary notice preserves your right to lien — but it does not file the lien. Under [A.R.S. § 33-993](https://www.azleg.gov/ars/33/00993.htm), a mechanics lien must be recorded in the county recorder's office in the county where the property is located within 120 days after the claimant last furnishes labor, materials, or equipment to the project. Once you record the lien, you must then file a lawsuit to foreclose the lien within six months of recording, or the lien is extinguished under [A.R.S. § 33-998](https://www.azleg.gov/ars/33/00998.htm). Both deadlines are hard cutoffs. There is no grace period and no mechanism to reinstate a missed lien. Check all your active Arizona project deadlines at once on the [LienFlash deadlines page](/deadlines). ## How Does Arizona's Lien Law Apply to Public Projects? On public construction projects — state, county, city, or other government-owned property — mechanics liens are not available because government-owned land cannot be liened. Instead, Arizona law protects subcontractors and suppliers through the Payment Bond requirements under A.R.S. § 34-222. On public projects with a contract value over $50,000, the GC is required to obtain a payment bond. To make a claim against that bond, you must serve written notice on the GC within 90 days after your last day of furnishing labor or materials. Failing to serve timely notice waives your right to a bond claim. The 20-day preliminary notice process is not required for public bond claims, but the 90-day notice to the GC is mandatory. ## Why Does the Arizona Preliminary Notice Matter Beyond Legal Compliance? Slow payments are endemic in construction. According to Rabbet's 2024 Construction Payments Report, 82% of contractors face payment waits of over 30 days, up from 49% just two years earlier. The average days sales outstanding in construction sits at approximately 90 days — double the 45-day threshold that financial experts consider healthy. A properly served preliminary notice does something practical beyond legal compliance: it puts the owner on notice that you are on the job and have protected lien rights. Owners who know a sub has lien rights often prioritize those payments over subs who haven't filed. The notice signals you know your rights and intend to use them. The math is straightforward. A single preliminary notice costs $24.99 through LienFlash. If it preserves lien rights on a $15,000 subcontract that would otherwise go unpaid, that is a 60,000% return on the cost of filing. On a $75,000 contract, the return exceeds 300,000%. ## What Happens if You Miss the Arizona Preliminary Notice Deadline? Missing the 20-day window does not immediately eliminate all your lien rights, but it does create a gap. Under [A.R.S. § 33-992.01](https://www.azleg.gov/ars/33/00992-01.htm), late service limits your lien protection to labor and materials furnished in the 20 days immediately before the date you actually serve the notice. Anything you furnished before that 20-day lookback window is permanently unprotected. If you realize you missed the deadline partway through a large job, serve the notice immediately — even late service protects the work you haven't done yet and recent work done in the last 20 days. If you never serve the notice at all, you lose all mechanics lien rights on the project, period. At that point, your only remedies are breach of contract claims or small claims court, neither of which carries the leverage of a recorded lien. ## Frequently Asked Questions ### Does a general contractor in Arizona need to serve a preliminary notice? No. General contractors who have a direct contract with the property owner are not required to serve a Preliminary 20-Day Notice under [A.R.S. § 33-992.01](https://www.azleg.gov/ars/33/00992-01.htm). The notice requirement applies to subcontractors, material suppliers, and equipment lessors who lack a direct contractual relationship with the owner. ### Can I serve the Arizona preliminary notice by email or fax? No. Arizona law requires service by certified mail with return receipt requested, registered mail, or personal delivery. Email and fax are not recognized methods of service under [A.R.S. § 33-992.01](https://www.azleg.gov/ars/33/00992-01.htm)(C). Using an unapproved delivery method means the notice is legally ineffective, even if the recipient actually reads it. ### What is the "first furnishing" date in Arizona? The first furnishing date is the calendar date you first deliver labor, materials, or equipment to the project site. This is the trigger for the 20-day preliminary notice deadline. It is not the contract execution date, the mobilization date, or the date you submit a quote. The day boots hit the ground or materials arrive on site — that is day one. ### Does Arizona require a Notice of Commencement to be filed before subcontractors can file a lien? Arizona does not require an owner to file a Notice of Commencement as a precondition to subcontractor lien rights, unlike some other states such as Florida. However, if an owner does record a Notice of Commencement, it provides important information — including the construction lender's identity — that subcontractors need to properly serve their preliminary notice. ### How long does a mechanics lien stay on an Arizona property? A mechanics lien recorded under [A.R.S. § 33-993](https://www.azleg.gov/ars/33/00993.htm) is effective for six months from the date of recording. If the lien claimant does not file a lawsuit to foreclose the lien within that six-month period under [A.R.S. § 33-998](https://www.azleg.gov/ars/33/00998.htm), the lien expires automatically. An expired lien has no legal force and cannot be reinstated. ### Can a sub-subcontractor (second-tier sub) file a lien in Arizona? Yes. Sub-subcontractors — those hired by a subcontractor rather than directly by the GC — have mechanics lien rights under Arizona law, provided they serve the Preliminary 20-Day Notice under [A.R.S. § 33-992.01](https://www.azleg.gov/ars/33/00992-01.htm). The notice must be served on the owner, the GC, and the construction lender. Second-tier subs who skip the preliminary notice lose their lien rights entirely. ### Does Arizona have a "notice of intent to lien" requirement before recording a mechanics lien? Arizona does not require a separate notice of intent to lien before recording a mechanics lien on a private project. Once the preliminary notice has been properly served and the 120-day recording deadline is approaching, you can record the lien directly with the county recorder. However, sending a notice of intent informally before recording is often a practical tactic to prompt payment without escalating to a formal lien. ### What county recorder do I file the Arizona mechanics lien with? You must record the mechanics lien with the county recorder in the county where the property is physically located. For example, a project in Phoenix would be filed with the Maricopa County Recorder; a project in Tucson would go to the Pima County Recorder. Filing in the wrong county is a fatal defect — the lien will have no effect on the property. ## Protect Your Lien Rights on Every Arizona Job Every Arizona job where you are not contracting directly with the owner carries payment risk. The preliminary notice is the only tool that preserves your legal leverage — and it has to be served within 20 days of first furnishing. There is no workaround for a missed deadline.
