Do I need a permit for hvac replacement or installation in Town of Groton?

Permit required

Yes. In Connecticut, hvac replacement or installation generally requires a permit, and Town of Groton is no exception.

The Connecticut code requires a permit to install, alter, repair, or replace any mechanical or gas system (CSBC R105.1); only portable appliances, minor parts, and small self-contained units are exempt (CSBC R105.2). Heating, piping, and cooling work requires a State occupational license (CGS 20-334). An owner may do electrical, plumbing, heating, cooling, and solar work in a single-family home the owner occupies or will occupy without a trade license, but the work still needs inspection and approval by the building official (CGS 20-340(11)); the exemption does not cover two-family homes or rentals. Connecticut does not adopt the International Fuel Gas Code; gas work follows NFPA 54 and NFPA 58 (CSBC R101.4.1).
