Arizona Statutes, Rules, and Contractor Regulation
The statutory frame
Arizona contractor law lives in A.R.S. Title 32, Chapter 10 (§ 32-1101 and following), with detailed rules in A.A.C. Title 4, Chapter 9. The Registrar of Contractors (ROC) issues licenses, investigates complaints, and can order a contractor to correct work or make a refund. Know the classifications: A (general engineering), B (general building), B-1 (general residential), B-2 (general small residential), B-3 (residential remodeling/repair), the C specialty trades, and dual licenses. A license covers only the classification and scope shown on it; a specialty license never authorizes whole-building work.
Licensing triggers
A license is required to offer or perform work, including labor and materials, valued at $1,000 or more. Residential work above that threshold requires a written contract containing the statutory items - scope, price, schedule, the ROC's contact information, and lien/notice disclosures. Advertising must carry the license number. Contracting without a license is a criminal offense and generally bars the unlicensed party from collecting compensation.
Traps in questions
- Assuming the ROC can award any damages; its remedial authority is bounded by statute.
- Assuming a license follows the owner into a new LLC - the entity, not the person, is licensed.
- Forgetting the threshold counts materials supplied, not just labor.
- Mixing up the ROC (licensing and complaints) with the AHJ (permits and inspections).
Rule of thumb: when a job's total price reaches $1,000, stop and confirm a license classification covers every trade in the scope.
