Summary of Permit/Approval Process

The Building Code. The purpose of the building code is to insure public safety, health and welfare insofar as they are affected by building construction, through structural strength, adequate egress facilities, sanitary equipment, light and ventilation, and fire safety: and, in general, to secure safety to life and property from all hazards incident to the design, erection, repair, removal, demolition or use and occupancy of buildings, structures or premises.

What is a building code? The building code controls all matters concerning the construction, alteration, addition, repair removal, demolition, use, location, occupancy, and maintenance of all buildings and structures and their service equipment. 2015 Michigan Building Code went into effect statewide on April 20, 2017.

Are building permits necessary? Before construction of a building or structure, and owner, or the owner's builder, architect, engineer, or agent shall submit an application in writing to the appropriate enforcing agency for a building permit. A permit is also required when the use or occupancy of a structure or portion thereof is changed.

A permit is not required for ordinary repairs. Please refer to the Check First page for details.   In some cases building permits are not required but a zoning approval may be needed.
