5.2 Construction Contract Terms & Provisions

Core Contract Provisions

Quick Answer: A well-drafted Arizona construction contract should address, at minimum: scope of work, payment terms, time for performance, warranties, indemnification, termination, and a dispute resolution clause.

Construction contracts range from short proposals to lengthy standard-form documents, but nearly all contain the following core provisions.

Scope of Work

The scope of work is the heart of any construction contract. It should describe the work in enough detail that a third party could understand what is included and what is excluded. Vague scopes — "build a deck" with no dimensions, materials, or finishes — invite change-order disputes and payment fights. Best practice ties the scope to plans, specifications, and applicable codes (the 2018 IRC for residential B work, or the 2018 IBC for commercial B-1/B-2 work).

Payment Terms

Payment terms should state the contract price (lump sum, unit price, or time and materials), progress payment schedule, retainage percentage, and conditions for final payment. Arizona does not mandate a specific retainage rate for private work, but retainage typically runs 5–10%. Contractors should also address Arizona Transaction Privilege Tax (TPT) — an Arizona tax on contracting activity paid by the seller/contractor, not the customer — when pricing the work.

Time for Performance

The time for performance clause sets the start date, milestones, and substantial completion date. It should address excusable delays (weather, owner changes, force majeure) and the consequences of non-excusable delay, including liquidated damages if the parties agree to a per-day amount.

Warranties

Construction contracts typically include a workmanship warranty (the contractor will repair defective work for a defined period) and pass through manufacturer warranties on materials. Arizona's ROC framework also imposes statutory obligations on licensees to perform work in a workmanlike manner, separate from any contractual warranty.

Indemnification

Indemnification clauses require one party to defend and hold harmless the other from third-party claims. In Arizona, indemnity provisions are generally enforceable but cannot require a party to indemnify against its own intentional misconduct or violations of law. Contractors should read indemnity clauses carefully — broad-form indemnity can shift significant risk.

Termination

Termination provisions distinguish between termination for cause (breach) and termination for convenience. The clause should specify notice requirements, payment for work performed, and the contractor's right to retrieve tools and materials.

Dispute Resolution Clause

A well-drafted dispute resolution clause sets the path for resolving disagreements: typically negotiation, then mediation, then arbitration or litigation. Specifying the forum (Arizona state court, federal court, or an arbitration provider) avoids later fights over where to file.

AIA-Style Contracts

The American Institute of Architects (AIA) publishes the most widely used standard-form construction contracts in the United States. Common AIA documents include:

• A101 — Standard Agreement between Owner and Contractor (Lump Sum)
• A102 — Standard Agreement between Owner and Contractor (Cost of Work Plus Fee)
• A201 — General Conditions of the Contract for Construction
• A401 — Standard Agreement between Contractor and Subcontractor

AIA's A201 General Conditions is the backbone document: it defines the roles of owner, contractor, and architect, and addresses changes, claims, time, payment, and dispute resolution. Many non-AIA contracts borrow A201's structure. Contractors should review A201 before signing any AIA-based contract.

Arizona-Specific Notice Provisions

Several Arizona notice rules shape contract performance:

1. License number disclosure — A licensed contractor must include the ROC license number on contracts, bids, and advertising
2. Preliminary 20-day notice (A.R.S. § 33-992.01) — A subcontractor or supplier not in direct contract with the owner must serve this notice within 20 days of first furnishing labor or materials to preserve mechanics' lien rights
3. Notice of completion — Owners may record a notice of completion, which affects lien deadlines

Subcontractor Agreements

A subcontractor agreement between the general contractor and a subcontractor should:

• Incorporate the general contract by reference so the subcontractor is bound to the owner-contractor agreement's terms as they apply to the subcontractor's scope (the "flow-down" provision)
• Define the scope of the subcontractor's work clearly
• Set payment terms that track the general contractor's receipt of payment from the owner ("pay-when-paid" or "pay-if-paid" clauses, which Arizona courts interpret closely)
• Require insurance and licensing appropriate to the subcontractor's trade
• Address changes through the same written change-order process used in the prime contract

A clear subcontract agreement prevents the most common disputes: scope overlaps, payment delays, and mismatched change-order procedures.
