Vacaville, CA Fence Regulations: Pool Barriers (2026)

California's Swimming Pool Safety Act, codified at Health & Safety Code 115921-115929 and implemented through California Building Code Section 3109 (adopted under VMC Title 15), applies to every newly constructed or substantially remodeled pool and spa attached to or serving a private single-family home in Vacaville. The Act requires a building permit application for a pool or spa to include at least two of seven drowning-prevention safety features: (1) an isolation barrier separating pool from home meeting CBC 3109.4 specifications, (2) an approved removable mesh pool fence (ASTM F 2286), (3) an approved pool safety cover (ASTM F 1346), (4) exit alarms on all home doors with direct access to the pool, (5) self-closing/self-latching devices on doors providing direct access to the pool, (6) an alarm capable of alerting on water entry, or (7) a swimming-pool alarm meeting ASTM F 2208. The required isolation barrier under CBC 3109.4.1.1 must be at least 60 inches tall measured on the side facing away from the pool, with bottom clearance no more than 2 inches above grade (4 inches over a hard surface). Openings cannot allow passage of a 4-inch sphere. Gates must open outward from the pool, be self-closing and self-latching, with the release mechanism at least 54 inches above the ground. VMC 14.09.200 also requires a 3-foot setback from any property line for pools located in the rear or side yard. The Vacaville Building Division reviews barrier compliance during plan check and final inspection.
