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

Alameda Municipal Code §30-5.12 (Development Regulations / open space) addresses pool placement, not barrier height. Pools or spas constructed and/or permanently located 'in-ground,' and any mechanical equipment for them, may be located within a minimum required rear and side yard provided a minimum five-foot (5') setback is maintained from any property line. Portable pools, spas, hot tubs and similar features that the Building Official determines are not structures are not subject to the accessory-building setbacks or the in-ground setbacks, except that no mechanical equipment for such portable pools or spas may be placed within five feet (5') of any property line. The safety barrier itself follows statewide law that Alameda administers: under the California Building Code §3109.2 and Health & Safety Code §115923, an enclosure used to isolate a pool must be at least 60 inches (5 feet) high, have no more than a 2-inch ground gap, allow no opening through which a 4-inch sphere passes, and have self-closing, self-latching gates that open away from the pool with a latch released from inside, generally at least 60 inches above grade. Because these are state standards, Alameda does not publish a different fence height.
