Mechanical Permits

Effective Monday, March 1, 2021, all mechanical permits submitted to the City of Minneapolis must use the new, updated mechanical permit application form (to be posted online on March 1, 2021). Please clear your web browser(s) cache to remove any cookies tied to previous versions of this permit application.

Any older, previous versions will be rejected and a new version will be requested. The updated mechanical permit application form will reflect changes to our mechanical permit review process including information necessary for digital plan review in our Project Dox system.

Effective Monday, August 10, 2020, the City of Minneapolis will no longer accept, process, issue or inspect new permit submittals for radon mitigation systems in the City of Minneapolis.

Due to the resolution of recent legal challenges to State of Minnesota Department of Health requirements, radon mitigation permits must now be requested from the State of Minnesota Health Department.

Any open permits issued from the City of Minneapolis prior to August 10, 2020 will need to obtain final inspections from city inspection staff.

For all new residential construction and for additions to residential construction where a radon mitigation system is currently installed, these radon systems will continue to be reviewed and inspected as part of the overall building permit issued for the project – no additional mechanical permit is required.

Visit the Minnesota Department of Health websites for more information on Radon in HomesRadon Laws, Rules and Standards, and Licensing for Radon Professionals
