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

Pool barrier rules in Whittier come from two layers that both apply. The City layer is the 2021 International Swimming Pool and Spa Code (ISPSC), adopted by reference in Whittier Municipal Code Chapter 15.12. Under the ISPSC, an outdoor residential pool or spa must be surrounded by a barrier whose top is at least 48 inches above grade measured on the side facing away from the pool, with limited openings and a maximum gap at the bottom; pedestrian access gates must open outward away from the pool and be self-closing and self-latching, with the latch release positioned per the code. The State layer is California's Swimming Pool Safety Act, Health & Safety Code sections 115922 through 115928, which is enforced through the building permit. Section 115923 describes an enclosure at least 60 inches high with no more than a 2-inch ground gap, gaps that will not pass a 4-inch sphere, and gates that are self-closing and self-latching with the latch at least 60 inches above grade. For new pool construction or remodels, HSC 115922 requires the owner to equip the pool with at least two of seven approved drowning-prevention safety features (such as an isolating enclosure, approved safety cover, door and window alarms, or self-closing self-latching doors). Whittier's published 'Pool and Spa Requirements' handout incorporates these fence and gate requirements into the plan-check checklist. Where the City code and state law differ, the more protective standard controls in practice, so applicants should design to the 60-inch State enclosure height.
