Frequently Asked Questions
How do I verify a contractor's license in California?
Enter the contractor's name or license number in our free lookup tool. The report shows current license status, disciplinary history, bond information, and workers' compensation coverage sourced from official California state records.
What does an "active" license status mean?
An active license means the contractor has met all state requirements including bonding, insurance, and continuing education. It confirms they are legally authorized to perform work in their licensed trade classification.
Should I hire a contractor with an expired license?
Hiring a contractor with an expired or suspended license carries significant risk. Their bond and insurance coverage may have lapsed, which means you could be liable for injuries or property damage during the project. Always verify license status before signing a contract.
