Summary
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.
(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.
Full Breakdown
For backyard pools the Uniform Dwelling Code does not impose a barrier, so fencing is governed by local ordinance in each Rock County municipality or unincorporated town. Wisconsin's binding barrier rule is written for public and semi-public pools in SPS 390.18(4): the barrier must be at least 5 feet high, gates must be self-closing with a lockable latch at least 54 inches up, fence openings may be no greater than 4 inches wide, and the bottom may sit no more than 4 inches above grade. Many local pool ordinances mirror these dimensions for residential pools.
Violations & Fines
Public/semi-public pool operators failing SPS 390 barrier rules face DSPS enforcement and license action; residential fence violations are cited under the applicable municipal or town ordinance.
