What the contractor's bond covers

What this record does and does not tell you
The California Contractors State License Board (CSLB) tracks license status, classification, bond, and workers'-comp. It does not rate work quality, track general-liability insurance, or collect customer reviews. Use it to confirm the license is real and in good standing, then check references and a written contract separately.
What classification B covers
CSLB #330542 is classified General Building (B). A California contractor is licensed only for the classifications on record; work outside them may fall outside the license. The full classification list is on the official CSLB record.
