Waukesha, WI Swimming Pools & Spas: Fencing & Safety Requirements (2026)

Waukesha's private swimming pool fencing standard sits in the zoning code's accessory-use regulations at Sec. 58(2)(h). Every private pool must be walled or fenced with a detached wall or fence standing at least four feet high, positioned no closer than four feet to the pool's perimeter walls at any point, and built so children cannot wander in from the street or an adjoining yard. Every opening into that enclosure, meaning every gate, must carry a self-closing and self-latching device mounted at the top. The Code allows two ways to satisfy the requirement without a dedicated pool fence: if the entire lot is already enclosed by a detached wall or fence meeting the same four-foot, self-latching standard, the pool does not need a second fence; and an above-ground pool is exempt from the detached-fence rule if its attached deck sits at least 48 inches above grade and the deck's outer edge carries its own fence at least 32 inches high, again with a self-closing, self-latching gate and ladder at the opening.

On top of the zoning fence standard, Sec. 38 of the Municipal Code separately requires every gate required under Sec. 58(2)(h) to be fitted with a combination lock or key lock, and that lock must be engaged whenever no owner or invited guest is inside the fenced pool area. The Zoning Administrator and Building Inspector enforce these standards.
