What You Should Know to Report Suspicious Contracting Activity

No one benefits from unlicensed contracting. That's why CSLB has an Enforcement division that focuses on unlicensed activity and welcomes tips from licensed contractors to help catch those illegally taking away work.

Your tips could lead to an unlicensed operator being invited to an undercover sting operation or help with the investigation of a consumer complaint.

Please note that it's important that you provide our Statewide Investigative Fraud Team (SWIFT) with complete and detailed information about the activity on an active job site and indicate if there are employees on the project. The more information and evidence (including photos), the better.

There are three types of forms that can be used to share information with CSLB:

  1. Lead Referral Form
  2. Advertising Complaints
  3. Building Permit Complaints
