Passing the CSLB exam is a major milestone, but it is not the same thing as being fully ready to work under your license.

Most contractors who earn their Class B General Building license feel a sense of relief when the license arrives. And that relief is earned.

Two male construction workers wearing safety vests and hard hats review documents together at a work site.

Every year, contractors across California make a decision that quietly puts their entire future at risk. They take on work, or allow work to proceed, under a license that is not truly theirs.
