Walk-In Tubs in Minnesota

Census estimates put the median build year in Minnesota at 1979; about 20% of homes were built before 1950. Kitchens and bathrooms from this era often keep their original layout and plumbing. Decide early whether you want to move fixtures, since that changes the permit and the scope. Federal EPA rules require firms that disturb painted surfaces in homes built before 1978 to follow lead-safe work practices. Ask whether the company is EPA lead-safe certified.

About 26% of Minnesota's counties are in climate zone 7 (very cold), based on the U.S. Department of Energy's county map. In a damp climate, a bathroom exhaust fan that vents outside (not into the attic) helps prevent mold. Cold winters make exterior walls matter. If walls are opened, ask whether insulation will be added before they are closed. Check your own county's zone, since conditions differ across the state.

About 66% of homes in Minnesota are single-family houses, and about 72% of occupied homes are lived in by their owners.

Moving plumbing, adding electrical circuits or changing walls usually needs a permit; swapping fixtures in place usually does not. In Minnesota, building permits are issued by cities and counties, so the rules depend on where the home is. Ask the company who pulls the permit, and keep a copy of it.

The Department of Labor and Industry licenses residential building contractors and remodelers. Look up the company's license or registration before you sign.
