Arizona fire protection contractor licenses (C-16, R-16, CR-16)
Arizona licenses contractors, not individual techs, through the Registrar of Contractors (ROC).
As of Nov 4, 2026. Rules change, so confirm with the agency before you apply. Numbers in brackets link to the official source for each fact.
Three fire protection licenses
ROC issues separate licenses for commercial and residential work, plus dual licenses that cover both. [1]
C-16 Fire Protection Systems (commercial) covers installing, altering and repairing fire protection systems that use water, steam, gas or chemicals. That includes fire pumps, tanks, piping, valves and sprinkler heads, low voltage signaling, and flushing and testing. [1]
R-16 is the residential version and allows low voltage signaling; other electrical work must be subcontracted. CR-16 is the dual license covering both. [1]
Who holds the license
The license belongs to the business, not to the qualifying party. The business needs a regularly employed qualifying party with the necessary experience, knowledge and skills. [1]
A B-2 general small commercial contractor has to subcontract fire protection work to a properly licensed contractor. [1]
What we couldn't confirm
ROC's experience and exam requirements for the qualifying party are in a document we couldn't open during this check, so they're left out.
