City-specific rules exist: Milton, and Beloit have their own fencing & safety requirements rules that differ from Rock County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

(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.

Frequently Asked Questions

How tall must a public pool fence be in Wisconsin?

Under SPS 390.18(4), a public or semi-public pool barrier must be at least 5 feet high with self-closing, lockable gates and openings no greater than 4 inches.

Is there a state fence rule for backyard pools?

No statewide residential rule. The Uniform Dwelling Code exempts outdoor pools, so your town, city, or village sets any required fence.
