Maryland

State Adoptions

Maryland's law related to building codes is called the Maryland Building Performance Standards (MBPS). It requires each jurisdiction in Maryland 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).

State adoption authority falls under the Department of Labor and, by statute, adoption must occur 18 months after a new code edition is issued. Local jurisdictions have an additional 12 months to make local amendments and enforce the most current version of the state adopted codes. The Maryland Board of Plumbing is also housed under the Department of Labor and is the adoption authority for the statewide plumbing and fuel gas codes.
