Full Breakdown
Above-ground pools in El Cajon are regulated under the California Building Code and Swimming Pool Safety Act.

The 60-inch barrier rule applies: above-ground pool walls may count toward the barrier height if they are non-climbable and have self-closing, self-latching access points. Ladders must be removable or lockable when the pool is not in use. At least one additional safety feature is required per the Swimming Pool Safety Act: an approved cover, alarms, or self-closing doors.
