When is a building, plumbing, mechanical or electrical permit required?

The State Building Code requires permits to construct, enlarge, alter, repair, move, demolish or change occupancy of a building. In general, a permit is required for most construction projects where something is being built, repaired, replaced, or remodeled. 

The best way to find out if you need a permit is to contact Building Inspections at 507-645-3004. Discuss your plans with an inspector before you begin construction to determine needed permits. 

Permits are usually required for the following:

  • New buildings
  • Additions (bedroom, bathroom, basement finish, family room)
  • Residential work (deck, porch, garage, fence, fireplace, pool, water heater, water softener, furnace replacement)
  • Renovations (garage conversion, basement finish, kitchen expansion, siding, roofing)
  • Electrical
  • Plumbing systems
  • HVAC/mechanical systems (heating, ventilating, and air conditioning systems)
