Licensing
Do you need a license in New Haven?
Licensing for dryer vent installation work is set at the state and local level in Connecticut, and New Haven may add its own business-license or registration requirements on top. Always confirm current city and county rules before bidding work. For the statewide picture: Dryer vent installation can fall under building, mechanical, or contractor codes in Connecticut: installation tied to residential work may require a Home Improvement Contractor registration through the Department of Consumer Protection, and venting connected to HVAC or mechanical systems can intersect with the state's mechanical trade licensing and local building codes and permits. Because these requirements vary and change, verify current state and local rules with the Connecticut DCP and your municipality before installing. A NISCR certificate is a professional training credential, not a government license or contractor registration.
A NISCR Certificate of Completion confirms completion of NISCR training and examination. It is a professional credential, not a government license. Where local law requires a license to perform a service, the technician is responsible for obtaining it.
