Do You Need a Permit for a Deck, Remodel, or Addition?

A plain-English guide to building permits in Minnesota and Wisconsin.

Short answer: usually, yes. Most cities in Minnesota and Wisconsin require a permit for building a deck, adding on to your home, or doing any work that changes the structure, plumbing, or electrical.

When you typically need a permit

  • Decks — nearly always, especially anything attached to the house or above a set height.
  • Additions — always, since they change the home's footprint and structure.
  • Kitchen & bath remodels — usually, if plumbing, gas, or electrical is moved.
  • Basement finishing — yes, for framing, egress windows, electrical, and plumbing.
  • Garages & new construction — always.

Simple cosmetic work — paint, flooring, swapping a faucet — generally doesn't need a permit. Requirements vary by city, so it's always worth checking before you start.

Who pulls the permit?

We do. GR Construction handles the permits, schedules the inspections, and builds to code — so you don't have to navigate city hall or worry about a failed inspection down the road.

Why it matters

Permitted, inspected work protects your safety, keeps your homeowner's insurance valid, and prevents headaches when you sell — unpermitted additions and decks routinely derail home sales. It's worth doing right the first time.
