What is the AZ ROC (Arizona Registrar of Contractors)?
The Arizona Registrar of Contractors (AZ ROC) is the state agency that licenses and regulates contractors across Arizona. By state law, anyone performing construction work valued over $1,000 (including labor and materials) must hold an active ROC license in the correct classification. The ROC issues licenses, investigates complaints, and publishes disciplinary actions and a list of unlicensed violators.
ROC licenses are grouped by classification. Broadly: “B” is general building (residential or commercial), “R”/“CR” cover residential and specialty-residential trades, “C” covers commercial specialty trades, and “K” (dual) covers both. Each classification defines exactly what kind of work the license permits — a roofing license doesn’t authorize electrical work.
Hiring an unlicensed contractor for work that requires a license carries real risk: no access to the ROC’s recovery fund, limited legal recourse, and often uninsured work. That’s why verifying the license before signing matters — status, classification, expiration, and any disciplinary history.
PlumbIntel tracks the full AZ ROC roster — license status, classifications, disciplinary actions, and the unlicensed-violator list — fused with each contractor’s actual building-permit activity.

- They define the scope of work allowed — e.g. B (general building), R/CR (residential & specialty residential), C (commercial specialty), K (dual). A license only authorizes work in its classification.
