A.R.S. 32-1158: What a Contractor's Written Contract Must Include

Updated July 10, 2026
In Short

A.R.S. 32-1158 sets what a contractor's written contract must include in Arizona. For any job over $1,000, the contract must list the contractor's name, address, and license number, the jobsite, the completion date, the total price, and deposit and payment terms. It must also carry a complaint-rights notice in at least ten-point bold type, signed by both parties.

A.R.S. 32-1158 (Contract requirements; provision of documents and receipt at contract signing)

This is a government work (Arizona statute, administrative rule, or city ordinance) in the public domain. Always confirm the current official text at the source before relying on it.

A written contract is your first layer of protection when you hire a plumber or any contractor in Arizona. State law spells out what that contract must contain. A.R.S. 32-1158 is the statute. It applies to most residential jobs and forces the contractor to put the key terms in writing. If a contract skips these items, that is a red flag worth asking about.

What this statute says

A.R.S. 32-1158 sets a dollar trigger. It applies to "any contract in an amount of more than $1,000" between a contractor and a property owner. For any job above that line, the contract must be in writing. It must contain a specific list of information, spelled out in the statute.

What the contract must include

The statute lists the required terms. Your written contract must contain all of these:

  • The contractor's name, business address, and license number. The statute requires "the name of the contractor and the contractor's business address and license number." That license number lets you verify the contractor with the state.
  • The owner's name and mailing address, plus the jobsite address or legal description.
  • The date you and the contractor entered into the contract.
  • The estimated completion date for all the work.
  • A description of the work to be performed.
  • The total dollar amount you will pay for all the work.
  • The dollar amount of any advance deposit.
  • The dollar amount of any progress payment and the stage of construction it is tied to.

The complaint-rights notice

The statute adds one more required item, and it is a consumer protection. The contract must tell you that you can complain to the state if the contractor breaks the rules. It must state that the property owner has the right to file a written complaint with the Registrar of Contractors for an alleged violation. It must also give the registrar's phone number and website address.

This notice cannot hide in fine print. The statute requires it to appear "in at least ten-point bold type." The contract must then be signed by both the property owner and the contractor.

Your right to a signed copy

You are entitled to keep the paperwork. Once you both sign, the statute says "the contractor shall provide the owner with a legible copy of all documents signed." If you pay cash, you also get a written, signed receipt for the exact amount. Never accept a promise to send the contract later. Get your signed copy before work starts.

What this means for you

Before you sign, run down the list. Confirm the license number is on the contract. Then check that number with the state Registrar of Contractors. Make sure the total price, deposit, and payment schedule are written out in dollars. Look for the bold complaint-rights notice. If it is missing, the contractor may not be following the rules that protect you.

A solid written contract also supports your other rights. If the work goes wrong, you can file a complaint against the contractor. These consumer protections apply to licensed contractors. That is one more reason to confirm the difference between a licensed contractor and a handyman before you hire. For serious losses caused by a licensed contractor, you may also reach the Residential Contractors' Recovery Fund.
