Trade business resources for Connecticut.

In Connecticut, trade and home improvement contractors are licensed through the Department of Consumer Protection (DCP), which oversees both specialty trade licenses and the Home Improvement Contractor (HIC) registration. Licensing requirements vary by trade, with electricians and plumbers governed by separate examining boards under DCP, while general home improvement work requires registration rather than a full contractor's license.

Connecticut requires electricians to hold a state license (E-1 Master Electrician, E-2 Journeyman, or limited specialty classifications) issued by the Electrical Work Examining Board. Plumbers and gasfitters are licensed through the Plumbing and Piping Work Examining Board, with Master (P-1) and Journeyman (P-2) tiers. HVAC/mechanical contractors typically need an S-1 or S-2 (sheet metal/heating) license or an oil burner technician registration depending on the scope of work. General contractors and roofers performing home improvement work on residential properties (1-4 units) must register as a Home Improvement Contractor (HIC) if the work exceeds $200; there is no separate GC license for residential work, but new home construction requires a New Home Construction Contractor (NHCC) registration. Commercial general contracting does not require a state-level license, though local building permits and insurance are mandatory. All contractor registrations and licenses are administered by DCP.
