The Sprinkler mandate on new homes over 4,500 square feet to be required to install a fire sprinkler system has been ruled Invalid by Minnesota Court of Appeals.
It appears part of the decision was that the Judge determined the mandate did not meet “scientific principles, approved tests, and professional judgement.” and also that it “violated statutory rulemaking procedures..”
D E C I S I O N
For the reasons outlined above, we declare the Energy Code to be valid. However, the Sprinkler Rule’s exception for new one-family dwellings under 4,500 square feet is arbitrary and not supported by the record. Therefore, we conclude that petitioner has 19 demonstrated that it was not the result of the application of scientific principles, approved tests, and professional judgment. Further, we conclude that respondent violated statutory rulemaking procedures by failing to adequately address the costs of complying with the Sprinkler Rule for small businesses and cities. Consequently, we declare the Sprinkler Rule invalid. Declaratory judgment issued.
