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.

A California contractor license is generally required when a project costs $1,000 or more in combined labor and materials, requires a building permit, or uses additional workers. Small jobs cannot be split from a larger project to qualify for the exemption. Read the CSLB requirements.
