Heating, Air Conditioning & Refrigeration
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, infloor (plex) or baseboard heating.
- Connect gas appliances to gas piping (heating systems only).
- Replace and install air conditioning
- Low temp refrigeration
- Radon mitigation system (must be installed by a licensed contractor)
Note: A licensed contractor must get the permit and perform the work of connecting the gas. Find a licensed contractor:
RESIDENTIAL HVAC REPLACEMENT PERMIT:
LEVEL 1: Includes Miscellaneous HVAC Work – No Burners
LEVEL 2: Includes any Level 1 work and replacement of boiler/furnace
LEVEL 3: Includes any Level 1 or 2 work and entire system replacement
Heating, air conditioning, and refrigeration for commercial, new construction and radon mitigation system
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. All gas piping and gas venting for heating appliances must be done by a licensed gas installer and requires a separate permit before this permit is issued.
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.
