Prefabricated building requirements
Construction of prefabricated buildings, which is governed by the Minnesota State Building Code, are those structures that are intended for use as one- or two-family dwellings or accessory buildings of "closed construction." Closed construction means they are built so that concealed parts or processes of manufacture can't be inspected at the site without disassembly.
This regulation is similar to that in Chapter 1361 for modular and industrial buildings. But it differs in that it is intended for those small manufacturers, particularly those lumber yards or vocational schools, that construct no more than three buildings each year for permanent installation. When a permanent seal and data plate is affixed to each building or building module, that shows it is in compliance with the State Building Code.
Construction of prefabricated buildings is governed by Minnesota Rules, Chapter 1360
