Minneapolis has some of the most demanding furnace requirements in the country. Temperatures routinely drop to -20°F or colder, and your furnace is a life-safety appliance — not just a com fort item. Here's everything Minneapolis homeowners need to know about furnace installation.
Minneapolis Permit Requirements
All furnace installations in Minneapolis require a mechanical permit from the City of Minneapolis Inspections Services Division. Permits cost $75–$200 depending on job scope. Work must be performed by a licensed contractor (Class A or C license for gas work in Minnesota). DIY gas furnace installation is not legal in Minneapolis.

What Minneapolis Code Requires
• High-efficiency furnaces (90%+ AFUE) require PVC flue piping — not metal — vented out the side of the house
• Two-pipe systems (combustion air + exhaust) are required for 90%+ AFUE
• Carbon monoxide detectors required on every level with sleeping areas
• New furnaces must be properly sized using Manual J load calculation
• Gas line work requires a separate gas permit
