Subcontractors and suppliers on Arizona public construction projects cannot file a mechanics lien against government-owned property — but under Arizona's Little Miller Act (A.R.S. § 34-222 and § 34-223), the prime contractor is required to obtain a payment bond, and that bond is your substitute remedy when a GC or upper-tier sub fails to pay. To preserve your right to make an Arizona payment bond claim on a public project, first-tier subcontractors and suppliers dealing directly with the prime contractor have no preliminary notice requirement, but claimants who do NOT have a direct contract with the prime contractor must serve written notice on the prime contractor within 90 days of last furnishing labor or materials, under A.R.S. § 34-223(B). All claimants must then file suit on the bond within one year of last furnishing. Missing either deadline extinguishes your claim.
What Is Arizona's Little Miller Act and Who Does It Protect?
Arizona's Little Miller Act is the state law that requires payment bonds on public construction projects and gives unpaid subcontractors and suppliers the right to claim against those bonds. Specifically, A.R.S. § 34-222 requires the prime contractor on any public works contract exceeding $100,000 to furnish a payment bond in an amount equal to the full contract price, conditioned on the prompt payment of all persons supplying labor or materials under the prime contract.
The statute covers a defined group of claimants. Under A.R.S. § 34-223(A), the following parties have bond claim rights:
- Subcontractors who contracted directly with the prime contractor
- Suppliers who furnished materials directly to the prime contractor
- Sub-subcontractors and suppliers who furnished labor or materials to a first-tier subcontractor (one step removed from the prime)
Third-tier claimants — those two or more steps removed from the prime — are generally not protected under Arizona's Little Miller Act. This is one of the most common eligibility mistakes subcontractors make. If you are a supplier to a sub-subcontractor, your rights under this statute may not exist. When in doubt, verify your tier before relying on this remedy.
The bond requirement applies to contracts with state agencies, counties, municipalities, school districts, and other public bodies. Private projects — even large commercial jobs — use a different set of rules and remedies.
Is There a Preliminary Notice Requirement Before Filing an Arizona Payment Bond Claim?
Whether you need to serve a preliminary notice before making an Arizona payment bond claim depends entirely on your contract tier.
First-tier claimants — those with a direct contract with the prime contractor — do not need to serve any preliminary notice to preserve bond claim rights under A.R.S. § 34-223. Your right to claim against the bond exists by virtue of your direct relationship with the prime.
Second-tier claimants — subcontractors or suppliers who contracted with a first-tier sub, not the prime — must serve written notice on the prime contractor within 90 days after the date on which the claimant last performed labor or last furnished materials. This requirement is established in A.R.S. § 34-223(B).
This 90-day notice is not the same as the Arizona 20-day preliminary notice used for private project lien rights. These are two separate statutes with separate purposes. If you are working on a public job and also want to protect private lien rights on a mixed-use project, consult the requirements under A.R.S. § 33-992.01 as well.
For second-tier claimants, this notice must be in writing and must be served on the prime contractor. Arizona law does not specify a single mandatory delivery method in A.R.S. § 34-223, but using a method that creates proof of delivery — such as certified mail — is strongly advisable. You need to be able to prove the notice was received.

What Is the Deadline to File an Arizona Payment Bond Claim?
Every claimant who has properly preserved bond rights must bring a civil action on the payment bond within one year after the date on which the claimant last furnished labor or materials, under A.R.S. § 34-223(C).
This is a hard deadline. There is no exception in the statute for disputes, negotiations in progress, or partial payments that reset the clock. The one-year period runs from the last date you actually furnished labor or materials on the project — not from the invoice date, not from the payment due date, and not from the date you sent a demand letter.
Two deadlines to track:
| Claimant Tier | Notice Deadline | Suit Deadline |
|---|---|---|
| First-tier (direct with prime) | None | 1 year from last furnishing |
| Second-tier (contracted with a sub) | 90 days from last furnishing | 1 year from last furnishing |
Mark both dates from the moment your crew finishes on the job or your last delivery hits the site. Do not wait until you receive a denial or a bounced check. The clock starts running the day you stop working.
What Documentation Do You Need for an Arizona Public Bond Claim?
Strong documentation is what separates a paid claim from a dismissed one. Before you file suit or even send your written notice, you should have the following assembled:
Project identification documents:
- The prime contract number and public agency name
- The name and address of the prime contractor
- The bond number and name of the surety (the bonding company) — this is typically available through a public records request to the contracting agency or via the bond itself, which prime contractors are required to keep on file
Proof of your contract and work performed:
- Your subcontract or purchase order with the party who hired you
- Invoices or billing statements showing amounts due
- Delivery receipts, field tickets, certified payroll records, or lien waivers that document what was furnished and when
- A clear record of the last date you furnished labor or materials (this is your deadline anchor)
Proof of non-payment:
- Any correspondence showing that payment was demanded and not received
- Bank records showing no payment received for the invoiced amounts
Notice documentation (second-tier claimants):
- A copy of the written notice sent to the prime contractor
- Proof of delivery — a USPS Certified Mail tracking confirmation and Certificate of Mailing, or a signed acknowledgment from the prime
If you served notice via certified mail, save the tracking number, the postmarked envelope scan, and the delivery confirmation. These are the documents that prove your notice was timely. Sureties and courts look for exactly this kind of paper trail.
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. In an environment where slow payment is the norm rather than the exception, having your documentation organized before a dispute arises means you can act immediately when payment stops.
How Do You Actually File an Arizona Payment Bond Claim?
Filing an Arizona payment bond claim is a legal proceeding — it is not a form you submit to a government office. Here is the sequence:
Step 1: Identify the bond and the surety. Request the payment bond information from the public contracting agency. Under A.R.S. § 34-222(C), prime contractors are required to provide a copy of the bond to any subcontractor or supplier upon request. Get the surety's name, the bond number, and the surety's contact address.
Step 2: Send written notice if you are a second-tier claimant. If you did not contract directly with the prime, send your written notice to the prime contractor before the 90-day window closes. Include your name and address, the name of the party you contracted with, a description of the labor or materials furnished, and the amount claimed.
Step 3: Send a demand letter to the surety. Before filing suit, send the surety a formal written demand for payment. Include your contract documentation, invoices, and proof of non-payment. Sureties are required to investigate and respond. Many claims resolve at this stage without litigation.
Step 4: File suit in the appropriate court within one year. If the surety denies your claim or fails to respond adequately, you must file a civil action in Arizona superior court within one year of your last furnishing date. Under A.R.S. § 34-223(C), the action must be brought in the county where the public construction project is located.
For the demand letter and the lawsuit, consult a licensed Arizona attorney. These are legal documents with legal consequences, and an attorney familiar with Arizona's Little Miller Act can ensure your claim is properly framed.
What Are Subcontractor Rights Under Arizona's Public Works Bond?
Subcontractors and suppliers who meet the eligibility and notice requirements have the right to recover the full unpaid amount for labor and materials furnished, plus interest. A.R.S. § 34-223 does not cap recovery at some percentage of the bond — you can claim the full amount you are owed, as long as it falls within the total bond amount.
Arizona's Little Miller Act also protects wages. A subcontractor's employees who go unpaid may have separate rights under Arizona wage laws, but the payment bond is the primary mechanism for subcontractors recovering contract amounts for labor and materials furnished on public work.
One practical point: the bond amount equals the full prime contract price under A.R.S. § 34-222. On large public projects, that means there is meaningful security behind your claim. On smaller projects just over the $100,000 threshold, multiple claimants sharing a bond can reduce individual recoveries if total claims exceed the bond amount — another reason to act promptly.
According to Rabbet's 2024 Construction Payments Report, slow payments cost the U.S. construction industry an estimated $280 billion in 2024, adding roughly 14% to total construction spending. Payment bonds exist precisely because subcontractors on public jobs bear real financial exposure when GCs or upper-tier subs fail to pay — and mechanics liens are legally unavailable against government-owned property.
Common Mistakes That Kill Arizona Payment Bond Claims
The following errors account for most failed bond claims:
Misjudging your contract tier. If you think you are first-tier but you actually contracted with a sub, you missed your 90-day notice window. Confirm your tier in writing before you start the job.
Using the last invoice date instead of the last furnishing date. The clock runs from when you last physically performed work or delivered materials — not when you billed for it. If your crew punched out for the last time on March 10, that is your anchor date regardless of when the invoice went out.
Assuming the GC's payment bond problems are temporary. Waiting for the GC to "work things out" with the owner can cost you your legal window. Do not let goodwill negotiations run out your clock.
Failing to get the bond number and surety information early. If you wait until you need to file a claim, getting bond information under time pressure is stressful and sometimes slow. Request bond info when you sign your subcontract.
Serving notice by email only. Arizona law does not specify certified mail for the second-tier notice under A.R.S. § 34-223, but email alone creates proof-of-delivery disputes. Use USPS Certified Mail. The USPS Certified Mail base fee is $4.85 in 2026 (per USPS Notice 123), which is a trivial cost against the amount of the claim.
Frequently Asked Questions
Does Arizona require a payment bond on every public construction project?
No. Under A.R.S. § 34-222, the payment bond requirement applies to public construction contracts exceeding $100,000. Contracts at or below that threshold do not carry the same statutory bond requirement, though a contracting agency may voluntarily require a bond on smaller projects. Always confirm whether a bond exists at the start of the project.
Can a supplier who sold materials directly to the owner — not the GC — make an Arizona payment bond claim?
Generally no. A.R.S. § 34-223 protects claimants who furnished labor or materials under the prime contract or under a subcontract with a first-tier subcontractor. A supplier who has a direct contract only with the project owner — not with the prime or a sub — falls outside the protected class.
What happens if the surety denies my Arizona payment bond claim?
You must file suit in Arizona superior court in the county where the project is located within one year of your last furnishing date under A.R.S. § 34-223(C). A surety denial does not pause or extend the one-year limitation period. Contact an Arizona construction attorney immediately after a denial to preserve your remaining time.
Does serving the 90-day notice guarantee I will get paid?
No. The 90-day notice preserves your right to make a claim against the bond — it does not create an automatic payment obligation. You still need to prove the amount owed, that you furnished the labor or materials, and that you were not paid.
Can I make a payment bond claim and also pursue the prime contractor directly?
Yes. Filing a bond claim against the surety does not prevent you from also pursuing breach of contract claims against the party who hired you or against the prime contractor. These are separate legal remedies that can be pursued simultaneously. An attorney can advise you on the most efficient strategy for your specific facts.
How do I find out which surety issued the payment bond on a public project?
Request a copy of the bond directly from the contracting public agency (the state department, county, school district, etc.). Under A.R.S. § 34-222(C), the prime contractor must provide a copy of the bond to any claimant upon request. The surety's name, address, and bond number will appear on the face of the bond.
What if the prime contractor goes out of business before I can collect?
This is exactly why the payment bond exists. The surety — not the prime contractor — is the party you are making the claim against. The prime's insolvency does not eliminate the surety's obligation under the bond, as long as you meet the notice and deadline requirements under A.R.S. § 34-223.
Is an Arizona payment bond claim the same as a mechanics lien?
No. A mechanics lien attaches to private property and is governed by A.R.S. § 33-981 et seq. Mechanics liens cannot be placed on government-owned property. A payment bond claim is a claim against a surety's financial guarantee — it is a separate legal remedy that exists specifically because liens are unavailable on public work. The deadlines, notice requirements, and procedures are entirely different.
