Verified from official government sources
Wisconsin's Uniform Dwelling Code does not regulate outdoor residential pools, so no county pool permit exists. Permits are set by your town, city, or village. In unincorporated towns the county's zoning site permit governs where the pool sits.
No county-wide residential pool fence rule exists; barriers are set by your town, city, or village. Wisconsin's statewide barrier standard (SPS 390.18) applies to public and semi-public pools: a barrier at least 5 feet high with self-closing, lockable gates.
Wis. Admin. Code SPS 390.18(4)
(d) The barrier shall be at least 5 feet in height. (e) Gates in the barrier shall be equipped with a self-closing, lockable closure mechanism at a height of at least 54 inches from the bottom of the gate. (f) Fences serving as barriers shall have no opening greater than 4 inches in width or diameter.
Wisconsin's enforceable pool safety code (SPS 390) applies to public and semi-public pools, covering barriers, warning markers, and depth signage. Backyard-pool safety is left to local ordinance; the county sets no residential pool safety standard.
Wis. Admin. Code SPS 390.18(3)
(3) Warning markers. (a) Pools or water attractions having water depths of 5 feet or less shall be provided with diving prohibition markers located on the deck at intervals of no more than 25 feet. (b) Diving prohibition markers shall be printed with the text, 'No Diving.'
Above-ground pools are not regulated by Wisconsin's Uniform Dwelling Code, so there is no county rule. Your town, city, or village decides on permits and barriers. In unincorporated towns, county zoning setbacks apply to where the pool is placed.
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.
