Low-voltage licensing by state

Every state regulates low-voltage work differently. Some have a unified state license (Texas, Florida, California). Some leave it to cities (New York, Illinois, Colorado). Some have classifications specifically for low-voltage installers; others roll it into general electrical contracting.

This guide is a free reference for installers, contractors, and anyone bidding low-voltage work across state lines. We aggregate public information from each state's regulatory agency and cite the original sources on every page. It is not legal advice - verify current requirements with the agency before applying.
