Application Requirements for Mechanical Permits

In accordance with the Minnesota State Mechanical Code (MSMC), permits are required for any installation, maintenance, alteration, and inspection of mechanical systems that are permanently installed and utilized to provide control of environmental conditions and related processes within buildings, fuel gas piping systems, fuel gas equipment and appliances, and related accessories. 

Note for contractors: Mechanical permit applicants (contractors) are not required to be licensed by the State of Minnesota but are required to file a $25,000 mechanical contractor bond with the Minnesota Department of Labor and Industry (DLI) in order to contract to perform gas, heating, ventilation, cooling, air conditioning, fuel burning, or refrigeration work in Minnesota. The bond must be approved by DLI and written by a surety company licensed to do business in Minnesota.
