Arizona L-67 Low Voltage Contractor License Requirements (2026)

The Arizona Registrar of Contractors (ROC) issues the L-67 (commercial) and CR-67 (residential) Low Voltage Communication Systems specialty classifications under A.R.S. §32-1101 and A.A.C. R4-9. The L-67 / CR-67 covers telephone, intercom, sound, paging, audio/video, structured cabling, fiber optics, and signaling under 91 volts. Burglar alarm, monitored CCTV, and access control are additionally regulated by the Arizona Department of Public Safety (DPS) Licensing Unit, which issues the Alarm Agent Certification under A.R.S. §32-101 et seq. Fire alarm installation generally requires the L-11 (commercial) or CR-11 (residential) Electrical classification plus State Fire Marshal acceptance under NFPA 72.

Where Applications Stall

The errors below are the ones that most frequently cost Arizona Low Voltage applicants time, drawn from the cited board guidance.

Treating L-67 as a burglar alarm license

L-67 is communication systems only. Burglar alarm and monitored CCTV require an Arizona DPS Alarm Agent Certification.

Confusing L-67 with L-11

L-67 cannot install fire alarm systems. Fire alarm requires L-11 / CR-11 Electrical plus NFPA 72 acceptance.

Underestimating the bond requirement

The ROC contractor bond scales with annual gross volume. Contractors who underestimate volume have their bond called by ROC.

Missing DPS fingerprints for alarm work

Every Alarm Agent must hold a current DPS / FBI fingerprint clearance card.

Letting the L-67 renewal lapse

ROC suspends licenses 30 days after expiration. A delinquent license cannot be reinstated after one year and the qualifier must re-test.
