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.
