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. 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.
