How to Get Your C-7 Low Voltage Systems License in California

If you install low voltage systems, the C-7 license lets you take jobs of any size legally. You need to pass two exams, and you can study for both online.

What the C-7 license covers

The C-7 is for contractors who install low voltage systems that run on limited energy.

  • Security and alarm systems
  • Data and communication cabling
  • Audio and video systems
  • Low voltage controls

C-7 license requirements

  • At least four years of journey-level experience in low voltage work within the last ten years
  • Pass the C-7 Low Voltage Systems trade exam
  • Pass the CSLB Law and Business exam
  • A $25,000 contractor license bond
  • Workers’ compensation insurance if you have employees
  • Fingerprinting and a background check

How to get your C-7 license, step by step

  1. Confirm your experience. Make sure you have four years of low voltage experience and someone who can verify it.
  2. Submit your CSLB application. We help you fill it out correctly so it isn’t sent back.
  3. Study for both exams online. Work through the trade and Law and Business material and practice tests at your own pace.
  4. Pass your exams. Pass our practice tests first, and if you don’t pass the CSLB exam the first time, we pay your retest fee.
  5. Get your bond and insurance, and receive your license.

C-7 license questions

How many exams do I need to pass for the C-7?

Two: the C-7 Low Voltage Systems trade exam and the CSLB Law and Business exam. Our online course prepares you for both.

How much experience do I need?

CSLB asks for at least four years of journey-level experience (or as a foreman, supervisor, or owner) in low voltage work within the last ten years. Someone who knows your work signs off on it.

Can I study for the C-7 online?

Yes. Our online course covers both exams, with practice tests and help with your CSLB application, on your own schedule, in English or Spanish.

When do I need a license?

In California, you need a contractor license for jobs worth $1,000 or more, including labor and materials. Working without one on jobs above that amount can lead to fines.
