How can I report unlicensed activity?

This section explains how consumers, building officials and legitimate licensed contractors can report alleged unlicensed activity to CSLB.

Contact SWIFT

CSLB's Statewide Investigative Fraud Team (SWIFT) receives complaints against unlicensed individuals actively working on a construction project where the cost for labor and materials is $500 or more.

Reporting unlicensed activity

The best way to let CSLB know about unlicensed activity is by downloading a SWIFT Lead Referral form from this website. After completing the form, fax or mail it to the appropriate SWIFT office, based on the county where the alleged unlicensed activity is taking place.

Please Note: It's important that you provide SWIFT with complete and detailed information about the unlicensed activity and indicate if there are employees on the project. The more information and evidence the better.

Complaints are processed according to the date of receipt, priority, and staff availability if the job site is located in a remote area. The complaint will be assigned to an Enforcement Representative who will follow-up on the information provided.
