Did You Know? What California’s C-7 License Covers on an AV Project

A conference room upgrade might start with a new display and camera. Once the project involves running network cable above the ceiling, installing microphones and speakers, or wiring a room control system, it’s worth asking who will handle the low-voltage installation and what license they hold.

What is a C-7 license?

California’s Contractors State License Board (CSLB) calls C-7 the Low Voltage Systems Contractor classification. It covers installation, service, and maintenance of energy-limited communications and low-voltage systems operating at 91 volts or less. CSLB lists sound systems and closed-circuit video as examples. Low-voltage fire alarm systems are outside the classification’s scope.

What does that mean for your project?

Say you’re upgrading a boardroom for Microsoft Teams Rooms or Zoom Rooms. The project might include new data drops, ceiling microphones, speakers, and a touch panel. If the room also needs a new 120-volt outlet behind the display, ask your project team who’s handling that electrical work and who’s handling the low-voltage installation. Getting that into the scope early can help avoid a last-minute change order.

Before approving a proposal, ask for the contractor’s license number and check its status and classifications with CSLB.

What about a certificate of insurance (COI)?

Before your AV contractor comes onsite, ask for a certificate of insurance (COI) and compare the listed coverage, limits, and policy dates with your building or contract requirements. Check the policies your project calls for, such as general liability and workers’ compensation.

If your building or contract requires an owner, property manager, or general contractor to be named as an additional insured, ask for documentation showing how the policy grants that status. A COI summarizes insurance information. Additional insured status comes from the policy terms or an endorsement.
