  2. Re-check the same number on CSLB's Instant License Check the day you sign; our copy is refreshed weekly and 6.2% of Livermore listings here already show a suspension.
  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.
