California low voltage contractor license guide
California low voltage contractors use CSLB's C-7 Low Voltage Systems Contractor classification. This guide maps security cameras, sound, communication, controls, and similar low-voltage work to official CSLB source materials.
California low voltage contractors should review CSLB's C-7 Low Voltage Systems Contractor classification before selling communication, sound, closed-circuit video, satellite, instrumentation, temperature-control, or low-voltage landscape-lighting work. CSLB's C-7 description says low voltage fire alarm systems are not included.
Who this applies to
- California contractors installing, servicing, or maintaining energy-limited communication and low-voltage systems should review the C-7 classification.
- Security camera, smart-home, low-voltage lighting, sound, networking, and control work can overlap with electrical, alarm, locksmith, and local permit requirements.
- Homeowners and contractors should verify CSLB license status before contracting for wired security, camera, audio, or control-system installation.

Practical application path
- Read CSLB's C-7 classification page before advertising low-voltage installation or service work.
- Confirm whether the planned work is C-7 low voltage, C-10 electrical, alarm/fire alarm, locksmith/security, or another regulated scope.
- Identify the qualifying individual and gather verifiable low-voltage systems experience documentation.
- Follow CSLB's application, exam, fingerprinting, bond, and issuance instructions.
- Confirm local permit, inspection, alarm, access-control, and fire-code requirements before starting jobs.
Watchouts before you sell the work
- Do not treat all security, camera, alarm, access-control, and electrical work as the same scope.
- CSLB's C-7 page specifically excludes low-voltage fire alarm systems.
- Projects involving line voltage, fire systems, monitored alarms, or door hardware may require a different license, permit, or specialist.
