San Leandro, CA Swimming Pools & Spas: Hot Tub Rules (2026)

The 2022 California Building Code §202 definition adopted in San Leandro's submittal handout expressly includes 'hot tubs, spas, portable spas and non-portable wading pools' within the term 'swimming pool.' That means a hot tub or spa holding more than 18 inches of water needs a building permit, must be inside a 5-foot non-climbable enclosure with self-closing self-latching outward-swinging gates (2022 CBC §3109.2 / H&S §115923), and must comply with the door-alarm rules for dwelling doors that open directly to the spa area (alarm sounds within 7 sec, runs ≥30 sec, auto-resets; deactivation ≤15 sec per opening). Spas rated at 240 volts must have a disconnecting means that simultaneously disconnects all ungrounded conductors. That disconnect must be readily accessible, within sight of the spa or hot tub, and located at least 5 feet horizontally from the inside walls of the spa, measured along the shortest path from the water's edge to the disconnect (2022 CEC §680.41). All spa circuits must be GFCI protected unless the listed packaged spa equipment assembly includes integral GFCI protection for all internal electrical parts. SB 442's two-feature drowning-prevention requirement (H&S §115922) also applies whenever a permit is pulled.
