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 J9 Engineering or J9 Solutions INC. A different company name on the paperwork usually means someone else is working under this license.

  3. Check the license covers your job

    This is a general engineering (a) license. If your job is a different trade, the contractor needs that license too, or a licensed sub for that part.
