Do I need a permit for hvac replacement or installation in Unincorporated Dorchester County?
Most likely yes. Hvac replacement or installation usually requires a permit in Maryland. Confirm the specifics with Unincorporated Dorchester County.
A new or relocated system, or one that burns gas, goes beyond a like for like change out and is not covered by replacement exemptions. Gas piping and venting normally require their own permit and a pressure test, and a relocated system usually triggers new duct, condensate, and electrical disconnect requirements. HVACR work requires a license from the State Board of HVACR Contractors (Business Regulation 9A-301); an individual owner of a single-family dwelling working on a building the owner owns is exempt from that license (9A-103), but local permits still apply. The State HVACR code is enforced by counties under agreements with the Board, and a county code adopted before 1988 applies in that county (Business Regulation 9A-205). Mechanical systems are outside the Maryland Building Performance Standards, so mechanical permit rules come from the local mechanical code.
