St. Paul, MN (KROC-AM News) - The State Court of Appeals has struck down a controversial addition to Minnesota’s building code.

The Dayton Administration enacted a rule in late January that requires the installation of sprinkler systems in larger new homes. The mandate covers single-family residences starting at 4500 square feet of space and was challenged by the Twin Cities Builders Association with support from the Rochester Area Builders Association and other similar organizations throughout the state.

In a ruling issued Tuesday, the Minnesota Appeals Court found the Sprinkler Rule’s exception for homes under 4,500 square feet is arbitrary and the regulation is not supported by substantial evidence.
