  1. Find the business in the list below, or search all 40 Brentwood listings, and open its profile. You want a Clear status and the C-36 classification (a B license can also cover it as part of a multi-trade job).

  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.
