Requirements for use of hot water pools on certain rental properties established.

HF 2147 exempts hot tubs or whirlpools on houseboats and single-unit rental properties from most public pool safety requirements in Minnesota. It requires property owners to ensure water temperature stays below 106°F, test chlorine/bromine, pH, and alkalinity before each rental, and provide renters with a specific notice about the exemption. The bill mandates a posted warning: "NOTICE: This spa is exempt from certain state and local sanitary requirements... USE AT YOUR OWN RISK." It directly affects rental property owners, resorts, and renters of these properties, while prohibiting local governments from adding extra requirements for qualifying hot water pools.
