How to check a structural steel contractor's license in Riverside

  1. Look the company up by name or license number (search Riverside). On the profile, confirm three things: Clear status, the C-51 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. Match the license holder's name to the name on the written contract and the person you meet. Ask for proof of workers' comp if anyone besides the owner will work on site. Hiring checklist.
