Do I need a permit for garage conversion in Unincorporated Caroline County?
Yes. In Maryland, garage conversion generally requires a permit, and Unincorporated Caroline County is no exception.
State law requires every county, Baltimore City, and municipality that enforces the Standards to issue building permits and inspect permitted work (Public Safety 12-505), and Maryland has no statewide exemption for converting a garage into living space. When a building permit is issued for an alteration to a one- or two-family home or for an additional residential unit, State law requires smoke alarm placement to be upgraded to at least one alarm on each level, including basements (Public Safety 9-104). Local jurisdictions may not weaken the energy code in the Standards (COMAR 09.12.51.05), so a converted garage that is heated or cooled must meet the 2021 IECC insulation and air sealing rules.
