2020 MINNESOTA STATE BUILDING CODES (CODE BOOK REQUIREMENTS)
The 2020 Minnesota State Building Code is effective March 31, 2020, except for the Minnesota Mechanical Fuel Gas Code, which is effective April 6, 2020.
It is the minimum construction standard throughout all of Minnesota. Although it is not enforceable by municipalities unless it is adopted by local ordinance, it creates a level playing field for the construction industry by establishing the Minnesota State Building Code as the standard for the construction of all buildings in the state.
