Brentwood, CA Fence Regulations: Pool Barriers (2026)

Swimming-pool barrier requirements in Brentwood are primarily set by California Health & Safety Code §115920-115929 (the Swimming Pool Safety Act) and the California Building Code, enforced by Brentwood Building Division. Fences enclosing pools must be at least 60 inches (5 feet) high, with no gaps exceeding 4 inches, and no footholds or climbable horizontal rails on the exterior. Gates must be self-closing and self-latching, with the latch at least 54 inches above the ground, and must open outward (away from the pool). For pools built or remodeled after January 1, 2007 (and stricter requirements after 2018), properties must have at least two drowning-prevention safety features from a state-approved list: isolation fence, removable mesh fence with lockable gate, approved safety cover, alarms on exit doors, self-closing/self-latching doors, or pool alarms. Real-estate transactions require a pool-safety disclosure. Enforcement occurs at building-permit inspection and in response to complaints. Violations can result in stop-work orders, required retrofits, and civil liability in the event of a drowning.
