A.R.S. 32-1121: Arizona's Owner-Builder Exemption

Arizona requires a contractor license for almost all construction, but A.R.S. 32-1121 carves out a short list of people who do not need one. The two exemptions that matter most for homeowners are the owner-builder exemption, which lets you build or improve your own property, and the minor-work exemption for small jobs. Both come with conditions, and missing a condition can drag you back under the license rule or void your work.

What this statute says

The owner-builder exemption lets a property owner act as their own contractor on their own property, as long as they do the work themselves, use their own employees, or hire licensed contractors. The catch is what you can do with the result. Here is the operative language:

Owners of property who improve the property or build or improve structures or appurtenances on the property and who do the work themselves, with their own employees or with duly licensed contractors, if the structure, group of structures or appurtenances ... are intended for occupancy solely by the owner and are not intended for occupancy by members of the public ... and are not offered for sale or for rent.

The exemption assumes you are building to live there, not to flip. If you sell or rent the property too soon, the law treats that as a sign you were really acting as an unlicensed contractor.

What this means for you

You can legally build or remodel your own home in Arizona without an ROC license under this exemption. A real example: you own a lot in Rio Verde and want to act as your own general contractor on your $700,000 custom home. You can, if you live in it yourself and you hire licensed trades for the work. But if you sell that home within one year of completion, the statute presumes you built it for sale, which means you needed a license you did not have. That presumption can expose you to penalties and can complicate the sale.

The second common exemption is for small jobs. Work of a casual or minor nature with a total contract price under $1,000 (labor and materials combined) does not require a license. But that exemption disappears the moment the work needs a local building permit, is part of a larger project, or the person advertising fails to disclose they are unlicensed. There are also hard carve-outs that never qualify for the minor-work exemption, including most electrical work and gas or propane line connections, because of the safety risk.

How this connects to the rest of the law

This section is the exemption door out of the broad contractor definition in A.R.S. 32-1101 . If you do not qualify for an exemption here, you need a license, which means meeting the qualifications in A.R.S. 32-1122 and choosing a class under A.R.S. 32-1102 . Even as an owner-builder, your local permit office still checks licensing under A.R.S. 32-1169 . The applied version of this question is can I build my own house in Arizona , and the role split is covered in custom home builder vs general contractor .

Whether a specific job qualifies for an exemption depends on the facts, so confirm with the ROC or a qualified attorney before relying on it.
