Low-voltage licensing
Arizona
Arizona regulates low-voltage work through the Registrar of Contractors (ROC). The L-67 classification (Low Voltage Communications Systems) is the primary low-voltage license, covering data, voice, sound, intercom, fire and burglar alarm. The C-11 (Electrical) is the broader electrical contractor classification.

Common pitfalls
Mistakes we see installers make when navigating Arizona licensing.
- Arizona requires a Qualifying Party - an individual who passes the trade and business management exams and is associated with the company. The Qualifying Party can only qualify one license at a time.
- Commercial (L-67) and residential (CR-67) are separate licenses with separate exams.
