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) accepts complaints against unlicensed individuals actively working on a construction project where the combined cost for labor and materials is $500 or more.

Reporting unlicensed activity

The best way to let CSLB know about unlicensed activity on an active job site is by completing the SWIFT Lead Referral form. After completing the form you may attach it to an email and send it to the appropriate SWIFT office. Use the email links below and select the appropriate SWIFT office based on the county where the alleged unlicensed activity is taking place. You may also fax and/or send the form by mail.

Please provide as much detailed information as possible about the unlicensed activity and indicate if there are employees on the project. Please include photographs if available.

Complaints are processed according to the date of receipt, priority, and staff availability.  If there is enough information the lead referral will be assigned to an enforcement representative for investigation.
