Guilford Center is a village area within the Town of Guilford (New Haven County), Connecticut. Connecticut does not license a generic “handyman,” but most paid residential repair/remodel work requires Connecticut Home Improvement Contractor (HIC) registration through the Department of Consumer Protection (DCP) unless a narrow exemption applies (e.g., certain new-home builders, some owner-occupant work). Separate state trade licenses are required for electrical, plumbing, HVAC/refrigeration, and gas piping work—those are not covered by HIC registration and generally cannot be performed by an unlicensed handyman.
