Workers’ compensation
This contractor has certified to the state that they have no employees, so they carry no workers’ compensation policy. The exemption covers only the license holder. If anyone else works on your project — a crew, a helper, a day laborer — they are not covered, and an injury on your property can become your liability. Ask who will physically be on site.
Are they licensed for your job?
A California contractor may only contract for work their classification covers. Pick the job and this reads the license on file against it.
