Lake County, CA Swimming Pools & Spas: Fencing Requirements (2026)

The County of Lake's published barrier handout (Part A, CBC Section 3109.4 as modified by the County) requires that a swimming pool be surrounded by a fence or wall at least 60 inches (5 feet) high. Acceptable enclosures include chain link of 2 1/4-inch square mesh (per 3109.4.1.5), vertical slat fencing with a maximum slat spacing of 4 inches, or masonry. Any other enclosure may be approved provided no opening (other than for doors and gates) allows a 4-inch-diameter sphere to pass through. Under Part B, item 1, the enclosure must meet additional standards: a minimum height of 60 inches; a maximum vertical clearance of 2 inches between the ground and the bottom of the enclosure; gaps that do not allow a sphere 4 inches or larger to pass; and an outside surface free of handholds or footholds a child under five could climb. Access gates through the enclosure must open away from the pool and be self-closing with a self-latching device placed no lower than 60 inches above the ground. Driveway gates that form part of the enclosure must be electronically operated and automatically close within one minute of being opened (the handout cites 15.04.131 P.C.C.). Barrier features such as covers, alarms, and door devices (Part B items 2-6) may substitute for the fence between the home and pool, but cannot substitute for the Part A perimeter fence.
