Each jurisdiction in Maryland is required to use the same edition of the same building codes that are the International Building Code (IBC), the International Residential Code (IRC), and the International Energy Conservation Code (IECC). The State has modified the IBC and the IRC to coincide with other Maryland laws. The International Building Code (IBC), the International Residential Code (IRC), and the International Energy Conservation Code (IECC), with modifications by the State, constitute the Maryland Building Performance Standards (MBPS). The International Plumbing Code, International Mechanical Code, and International Green Construction Code are also adopted by reference the MBPS. Each local jurisdiction in Maryland may modify these codes to suit local conditions with exception to the International Energy Conservation Code (IECC - The Energy Code) and Maryland Accessibility Code (MAC - The Accessibility Code).
