Mechanical/Heating Permits

Note: Many projects require more than one permit. To determine which permits you need for your project, call Minneapolis 311. If outside the Minneapolis city limits call (612) 673-3000.

A mechanical permit is required to:

  • Replace or install furnace or boiler.
  • Install ductwork, radiators, or baseboard heating.
  • Connect gas appliances to gas piping.

Note: A licensed contractor must get the permit and perform the work of connecting the gas. Find a licensed contractor

Licensing Requirements

If you are owner/occupant of a single-family home, you can apply for some mechanical permits for work that you intend to do yourself.

The City of Minneapolis issues licenses to heating/mechanical contractors. A contractor applying for a license must either hold a Certificate of Competency at the master level or employ a tradesperson who does.
