What this license means

California requires a CSLB license for any job where labor and materials cost $1,000 or more, and the license must cover the kind of work. Each classification (the letter-number codes) is one kind of work; a C-39 roofer can't contract for electrical work.

  2. Make sure the name on the contract matches

    The contract, the permit and the license should all name D One Construction Co. A different company name on the paperwork usually means someone else is working under this license.

    This is a general building (b), electrical (c-10) and 1 more license. If your job is a different trade, the contractor needs that license too, or a licensed sub for that part.
