Certain hot tubs exemption from public pool regulations provision

This bill exempts specific hot tubs from Minnesota's public pool regulations. It applies to hot tubs on houseboats rented to the public and hot tubs in single-unit rental properties (like vacation homes) used solely by renters. The key provision requires these hot tubs to display a mandatory notice stating: "NOTICE: This spa is exempt from state and local sanitary requirements... USE AT YOUR OWN RISK." This change directly affects rental property owners who operate these hot tubs, removing them from standard public pool safety and sanitation requirements.
