Sierra County, CA Swimming Pools & Spas: Safety Rules (2026)

Sierra County applies the California Swimming Pool Safety Act and the adopted California Building Standards Code rather than a distinct local pool-safety ordinance. Under Health & Safety Code section 115922, a new or remodeled residential pool or spa must include at least two of seven drowning-prevention safety features, which include an isolating enclosure (Health & Safety Code section 115923), approved removable mesh fencing, an approved safety cover, exit alarms on doors leading to the pool, and self-closing, self-latching devices on those doors. Health & Safety Code section 115928 requires every new pool to have anti-entrapment protection: hydraulically balanced suction outlets, generally at least two per pump separated by a minimum distance, fitted with approved anti-entrapment grates to prevent a swimmer from being trapped by suction. The County adopts these standards through its building-code reference in Sierra County Code section 12.04.080 (California Plumbing and Electrical Codes), which also covers required equipotential bonding of pool reinforcing steel and equipment. The Sierra County building official inspects the drowning-prevention features and equipment before granting final approval. Because the only city is Loyalton, the County administers these rules across all unincorporated communities.
