How to Get a Low Voltage (C-7) Contractor License in Riverside, CA

If you want to install, service, or maintain low-voltage systems in Riverside, California, it is important to understand how to obtain the appropriate license — specifically the C-7 Low Voltage Systems Contractor license issued by the California Contractors State Licensing Board (CSLB). This blog explains the requirements, process, and practical steps to secure that license so you can legally and confidently operate in Riverside.


What is the C-7 Low Voltage License

The C-7 classification covers contractors who work on low-voltage systems operating at 91 volts or less.
A C-7 contractor installs, services, and maintains communication and low voltage systems that are energy-limited and do not exceed 91 volts.
Typical systems include telephone and data systems, sound systems, cable TV, closed-circuit video, satellite dish antennas, instrumentation, temperature controls, and landscape lighting that operate within the voltage limit.
Fire alarm systems are not included under the C-7 classification.

Understanding this definition is essential because if your work exceeds 91 volts or involves high-voltage electrical systems, you will need a different classification such as the C-10 Electrical Contractor license.


Why Getting Licensed Matters in Riverside, CA

Operating without the correct license can lead to fines, penalties, and stop-work orders. In Riverside, licensed contractors must also obtain a valid City of Riverside business license before performing work. Having the C-7 license not only ensures compliance with California law but also builds trust with clients and provides credibility in a competitive local market.
