Executive Summary
- Arizona’s Prompt Payment Act establishes deadlines intended to promote timely payment for licensed contractors, subcontractors, and material suppliers on private and public construction projects.
- For most private projects, owners generally have 14 days to approve or deny a payment request and seven days to issue payment after approval. For public projects, approval is typically required within seven days, with payment due within 14 days. Contractors must pay subcontractors and suppliers within seven days of receiving funds.
- Late payments may result in statutory interest—1.5% per month on many private projects and 1% per month on public projects. In certain disputes, a court may award attorney fees to the prevailing party.
- The Act allows payment to be withheld in limited situations, such as defective work, unsatisfactory progress, damage, or unpaid financial obligations.
Understanding Arizona’s Prompt Payment Act
Arizona’s Prompt Payment Act is a collection of statutes designed to encourage timely and predictable payment practices within the construction industry. These laws apply to payment relationships among property owners or public entities, contractors, subcontractors, and material suppliers on qualifying projects throughout the state.
For most private construction projects, a property owner generally has 14 days after receiving a contractor’s billing to approve or reject it. Once approved, payment must be issued within seven days. On most public projects, progress payment requests are expected to be approved or denied within seven days, and payment must follow within 14 days. In both settings, contractors are required to pay subcontractors and suppliers within seven days after receiving payment.
When payments are late and no statutory exception applies, the Act allows interest and other remedies. For parties involved in Arizona construction contracts, understanding these timelines and requirements is an important part of managing risk and maintaining compliance.
What Is Arizona’s Prompt Payment Act?
Arizona’s Prompt Payment Act sets statutory deadlines for payments on private and public construction projects. By defining how quickly funds should move from owners or public entities to contractors—and then down to subcontractors and suppliers—the Act seeks to reduce extended payment delays and disputes.
Statutes Governing Private Construction Projects
Payment obligations for private-sector construction projects are primarily addressed in the following statutes:
- A.R.S. § 32-1181 – Definitions and applicability.
- A.R.S. § 32-1182 – Progress payment requirements and interest on late payments.
- A.R.S. § 32-1183 – Payment obligations between contractors, subcontractors, and suppliers.
- A.R.S. § 32-1184 – Suspension or termination of construction contracts.
- A.R.S. § 32-1185 – Rights to suspend performance or terminate a contract.
- A.R.S. § 32-1186 – Contract provisions that are void as against public policy.
- A.R.S. § 32-1187 – Statutory exclusions.
- A.R.S. § 32-1188 – Applicability to owner-occupied dwellings.
Taken together, these statutes establish when payments must be made and identify circumstances under which performance may be suspended or contracts terminated.
Laws Governing Public Construction Projects
Public construction projects in Arizona are subject to separate prompt payment requirements, including:
- A.R.S. § 34-221 – Payment timelines and dispute procedures for public works contracts.
- A.R.S. § 41-2576 – Procurement and payment administration for public projects.
- A.R.S. § 41-2577 – Compensation procedures for state construction contracts.
- A.R.S. § 28-6924 – Payment and penalty provisions for highway construction projects.
These statutes are intended to encourage consistent payment practices by public entities and provide remedies when deadlines are missed.
History of the Prompt Payment Act
At the federal level, Congress enacted a Prompt Payment Act in 1982 under Public Law 97-177, requiring the federal government to pay interest on overdue contract payments. Many states, including Arizona, later adopted their own prompt payment laws applicable to state and private construction projects.
Arizona enacted its first prompt payment statutes in 1989. Subsequent amendments—particularly those adopted in 2010—clarified billing timelines, addressed withholding for defective work, expanded notice requirements, and provided subcontractors with additional access to payment information. Further amendments in 2015 extended prompt payment protections to architects and engineers on many public projects.
Main Payment Timelines
Arizona’s Prompt Payment Act sets different deadlines depending on whether a project is private or public.
Private Construction Projects Relationship Owner to Contractor Contractor to Subcontractor Contractor to Supplier Payment Deadline Within seven days after invoice approval Within seven days after contractor is paid Within seven days after contractor is paid Invoice Approval 14 days after receipt Public Construction Projects Relationship Public Entity to Contractor Contractor to Subcontractor Contractor to Supplier Payment Deadline Within 14 days after approval; final payment generally within 60 days of project approval Within seven days after contractor is paid Within seven days after contractor is paid Invoice Approval Seven days after receiptNotice Requirements and Disputes
The Act requires timely written notice when payment is withheld or disputed. On private projects, owners generally must provide notice within 14 days of receiving a billing request. On public projects, public entities typically have seven days to approve or dispute an invoice and explain the reason for any withholding. Contractors who withhold payment from subcontractors or suppliers must also provide notice within seven days.
Consequences of Non-Compliance
When payment deadlines are missed without a valid statutory reason, interest may accrue. Private project disputes may involve interest at 1.5% per month under A.R.S. § 32-1182. Public project statutes, including A.R.S. § 41-2576 and A.R.S. § 41-2577, generally impose interest at 1% per month. Courts may also award reasonable attorney fees to the prevailing party in certain disputes.
Mechanics’ Liens and Payment Security
Unpaid contractors may have the ability to record a mechanics’ lien to secure payment. Arizona has specific lien requirements, including the use of a Preliminary 20-Day Notice. Only properly licensed contractors may assert lien rights, and filing deadlines vary depending on project completion and whether a Notice of Completion was recorded.
Mediation and Other Dispute Resolution Options
The Prompt Payment Act allows parties to pursue mediation or other alternative dispute resolution methods to address payment disagreements. These approaches may help resolve disputes more efficiently and preserve working relationships. If informal methods do not resolve the issue, arbitration or litigation may follow.
Exceptions and Limitations
The Act permits payment to be withheld under specific circumstances, such as defective work, failure to meet contract terms, third-party claims, or unpaid labor or supplier costs. Public project statutes provide similar grounds for withholding payment. Certain projects—such as some owner-occupied residential construction or work performed by unlicensed contractors—may fall outside the scope of the Act.
Practical Considerations for Compliance
Contractors and owners can reduce disputes by using clear contracts, maintaining accurate billing records, and communicating promptly when issues arise. Understanding statutory timelines and notice requirements can help parties address concerns early and avoid unnecessary delays.
Conclusion
Arizona’s Prompt Payment Act plays an important role in setting expectations for payment timing on construction projects across the state. By outlining deadlines, notice requirements, and remedies, the Act provides a framework for managing payment issues on both private and public projects.
When payment disputes arise, legal counsel can help parties evaluate their rights and obligations under the applicable statutes and determine appropriate next steps.
