Pleasanton, CA Swimming Pools & Spas: Fencing Requirements (2026)

Per the City of Pleasanton 'Residential Swimming Pool and Spa Review Requirements' handout (implementing Chapter 20.55 of the Municipal Code and CBC Section 3109), a swimming pool is any structure intended for swimming, recreational bathing, or wading that contains water over 18 inches deep, including in-ground, above-ground, and on-ground pools, hot tubs, spas, portable spas, and non-portable wading pools. A minimum 60-inch tall fence, pool barrier, or enclosure that completely surrounds all pools must be in place and maintained at all times. The pool enclosure must have a minimum height of 60 inches above grade, measured on the side facing away from the pool. The space between finished grade and the bottom of the enclosure must be less than 2 inches on the side facing away from the pool. All gaps or openings in the enclosure must not allow passage of a 4-inch-diameter sphere. The outside surface must be free of handholds or footholds that could enable a child under five to climb over. Access doors and gates must open outward away from the pool and be self-closing with a self-latching device; the release mechanism of the self-latching device must be at least 60 inches above the bottom of the gate on the outside of the enclosure. A removable mesh pool fence option must meet ASTM F2286 with a self-closing, self-latching gate that accommodates a lockable key device.
