Heating, Air Conditioning & Refrigeration
There are two types of permit application forms to choose from. If the work you are doing is replacing, altering, or modifying existing heating or cooling systems in a one or two family dwelling you must use the APPLICATION for HVAC WORK in EXISTING 1 & 2 FAMILY DWELLINGS. All other heating, air condition, and refrigeration work must be done under the HEATING / MECHANICAL APPLICATION. This includes new construction 1 & 2 family dwellings, townhouses, and multi-family dwellings.
Note: Gas fireplaces, water heaters, cooking appliances, and dryers must be done one a separate plumbing permit. Many projects require more than one permit. To determine which permits you need for your project, call Minneapolis 311. It outside the Minneapolis City limits, call (612) 673-3000.
A mechanical permit is required to:

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.
