The Baltimore market

Baltimore City's Department of Housing and Community Development (DHCD) requires a permit for changing, installing or replacing any electrical, gas, mechanical, HVAC and refrigeration or plumbing system. Only replacement of a minor part that does not alter equipment approval is exempt, and the city's exempt list does not include water heater replacement. Electrical, mechanical, gas and plumbing work requires a licensed contractor, and all permits require inspections by DHCD building and trade inspectors. Fees were not found, so ask DHCD. EIA's survey shows a mixed state: furnaces are main heat in 64% of Maryland homes, heat pumps in 19% and boilers in 7%, while 57% heat water with electricity. Baltimore County, which surrounds the city, is a separate jurisdiction with its own permit office, as are Howard and Anne Arundel counties.

Heat pumps show up more in newer suburban housing than in city rowhouses, but a rowhouse with an aging furnace and AC can still be a fit. Maryland's federal rebate programs are not open. The Maryland Energy Administration submitted updated applications to DOE on September 30, 2026, and launch depends on DOE review. Ask the contractor about utility rebates in the meantime. For a narrow rowhouse, ask whether a ducted system or ductless heads would suit the floor plan better.
