Hiring tip

Low voltage systems include data cabling, security, and fire alarm work. Some installations require permits and fire marshal approval. Verify the contractor is current with the latest code requirements for the specific system being installed.

California law requires a contractor license for this type of work on projects valued at $500 or more (combined labor and materials). Hiring an unlicensed contractor for work requiring a license may void your consumer protections.
