How to Check A Contractors License in CA

If you are hiring a contractor to build or remodel, the first thing to do before signing a contract or having them begin work, is to confirm they are currently licensed. Here are the steps to check a contractor's license in California.

Check the license before you start construction.

Step 1

You'll need either the license number or name of the contractor you'd like to check.  In general, contractors will add their license number to their website, business cards and any other marketing materials they use. If you are searching the Internet for contractors, it's a good idea to check their license status before calling them. 

Step 2

Go to the Contractors State License Board (CSLB) website - the URL is listed in the Resources below.  Click on the 'Instant License Check' button. The default search is by license number.  If you don't have that info, find the URL to search by 'Contractor name' or 'Contractor Personnel name'. Input the info you have and click 'Search for License'. 

Step 3

Review the CSLB results.  Confirm that the contractor has an active license and that they are licensed in the category of work you are requesting. For instance, a plumber might be listed in the HVAC category as well as plumbing, but not general construction.  The CSLB website also lists if the contractor is currently bonded (including the bond company name and amount of bond), and whether or not they carry Workers Compensation insurance.

Warning

  • Do not use an unlicensed contractor - the possible savings in initial costs doesn't outweigh the risk.
