Learn more →Why this exam matters
No matter what trade you are licensing in — B, C-10, C-36, C-46, any of them — you must pass the California Law & Business exam in addition to your trade exam. It is the same exam for every classification. Pass it once.
What it covers
The L&B exam samples the business and legal side of contracting in California. Topic weights vary year to year, but the seven areas below appear on every iteration of the exam.
Why it trips people up
Tradesmen often expect Law & Business to be easy because there is no technical math. In practice, this exam fails more first-timers than the trade exam — because the material is unfamiliar (most journeymen have never run payroll or filed a mechanic's lien). Treat it with the same respect as your trade exam.
