40.1% report a workers' comp exemption, 11.2 points lower than the statewide figure for electricians (51.3%), so many of these businesses say they have no employees. The share with a suspension, 4.4%, is 1.2 points higher than the San Bernardino County rate for the same license (3.2%).

14 of these licenses are less than a year old, while 51.1% have been held for 10 years or more. The median is 10.2 years.

In California this work generally calls for the C-10 Electrical Contractor license (or a B license when it is part of a larger multi-trade job). See the C-10 Electrical Contractor guide for what the license covers.

How to check an electrician's license in Ontario

  1. Look the company up by name or license number (search Ontario). On the profile, confirm three things: Clear status, the C-10 license for this kind of work, and a contractor's bond on file.
  2. Before any money changes hands, verify the license on CSLB's own lookup. Our data comes from CSLB's weekly file, so a very recent change may not show here yet.
  3. Ask for the pocket license and a photo ID and match the name to your contract. Work of $1,000 or more needs a license (the $1,000 rule), and a down payment can't exceed $1,000 or 10% (down payment rules).
