The California Building Code requires covered barriers for swimming pools, spas and hot tubs. By definition, a Swimming Pool is considered to be any structure that is intended for swimming or recreational bathing and contains water that is over 24 inches deep, including spas and hot tubs. This includes in-ground, above-ground and on-ground swimming pools, and fixed-in-place wading pools. A Barrier is a fence, wall, building wall or combination thereof that completely surrounds the swimming pool and obstructs access to the swimming pool. During construction of new pools, spas or hot tubs, the City inspector will enforce the barrier regulations by checking fence heights, gate operations, door alarms, and other associated requirements. A copy of the barrier requirements will be attached to the approved plans for his review. You can voluntarily make your pool, spa or hot tub environment a safe one for family and friends by putting these requirements into play. Community Development Permit Technicians within the Development Services Center will issue building permits for voluntary barrier upgrades for existing pools. For more information please call 510-494-4460 or stop by the Development Services Center office at 39550 Liberty Street. Office Hours are Monday through Thursday 8 a.m. to 4 p.m. and Friday 8 a.m. to noon.
