Maple Grove, MN Swimming Pools & Spas: Hot Tub Rules (2026)

Maple Grove's Residential Swimming Pools and Hot Tubs handout treats hot tubs and spas alongside pools. A building permit is required for swimming pools and hot tubs with a valuation exceeding $500. Any pool or hot tub exceeding 18 inches in depth or 150 square feet in area must comply with the city's rules whether or not a permit is required. The key exception for hot tubs is barrier-related: a hot tub with a lockable cover does not need a fence. A hot tub without a lockable cover that exceeds the size or depth thresholds would fall under the standard barrier requirements - a climb-resistant fence at least four feet high with self-closing, self-latching gates (latch at the top), no more than four inches of space underneath, and dwellings or accessory buildings permitted as part of the enclosure. Plans submitted with the permit application must show the hot tub's location relative to structures, lot lines, easements, and wetland buffers, plus the design of any required fence and gates. All water and drain connections must comply with the Minnesota Plumbing Code, and noise-generating equipment must be located in the rear yard. As a private residential installation, a backyard hot tub is regulated by the city building official rather than under Minnesota Rules Chapter 4717, which governs public pools and spas.
