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