Private residential hot tubs are not covered by Wisconsin's Uniform Dwelling Code, so Rock County sets no rule; check your town, city, or village. Public and semi-public spas must meet state SPS 390, including barrier and safety requirements.
A backyard hot tub or spa attached to a one- or two-family home falls outside the Wisconsin Uniform Dwelling Code, so Rock County imposes no countywide standard. Local municipalities may require electrical inspection or a barrier. In unincorporated towns, county zoning setbacks govern where a spa or its deck may sit. Spas that are public or semi-public (at motels, campgrounds, health clubs, or multi-family properties) are regulated by the state as water attractions under SPS 390, which requires plan approval and the same barrier standards as pools: a 5-foot barrier with self-closing, lockable gates.
Public/semi-public spa violations are enforced by DSPS under SPS 390; residential electrical or placement violations follow the local municipal or county-zoning ordinance.
