Current Codes, Rules, and Regulations

As established in Minnesota law, the primary purpose of the Minnesota State Building Code (MSBC) is to provide minimum standards to safeguard life and limb, health, property, and public welfare by regulating and controlling the design, construction, quality of materials, use and occupancy, location, and maintenance of all structures and equipment specifically covered by the code.

The Minnesota State Building Code (MSBC) contains various Minnesota rule chapters that regulate different parts of building construction. Although compiled as separate chapters, the compilation is identified as the Minnesota State Building Code. As part of the State rule-making process, national model codes are usually referenced for adoption. Minnesota also writes and adopts several of its own building construction codes. Some of these rules include: the Administrative Provisions of the Building Code, the Minnesota Plumbing Code, the Minnesota Energy Code, and the Minnesota Accessibility Code.
