Summary
Chino's Building Code amendment sets detailed pool-barrier specs, a 60-inch minimum height and openings that block a 4-inch sphere, that must be installed and approved before a pool is filled.
An outdoor swimming pool shall be provided with a barrier that shall be installed, inspected, and approved prior to plastering or filling the pool with water. The top of the barrier shall be at least sixty inches (1,524 mm) above grade, measured on the side of the barrier which faces away from the swimming pool. The maximum vertical clearance between grade and the bottom of the barrier shall be two inches (51 mm) measured on the side of the barrier which faces away from the swimming pool. The maximum vertical clearance at the bottom of the barrier may be increased to four inches (102 mm) when grade is a solid surface such as a concrete deck, or when the barrier is mounted on the top of the aboveground pool structure. When barriers have horizontal members spaced less than forty-five inches (1,143 mm) apart, the horizontal members shall be placed on the pool side of the barrier. Any decorative design work on the side away from the swimming pool such as protrusions, indentations or cutouts, which renders the barrier easily climbable, is prohibited.
3109.3.1.1 Openings. Openings in the barrier shall not allow passage of a four-inch (102 mm) diameter sphere.
EXCEPTIONS:

Full Breakdown
Chino's amendment adding CBC § 3109.3.1 requires an outdoor swimming pool barrier to be installed, inspected and approved before the pool is plastered or filled with water. The barrier top must be at least 60 inches above grade, with a maximum 2-inch clearance at the bottom (4 inches over a solid deck), and openings can't allow passage of a 4-inch-diameter sphere. Access gates can be no wider than 4 feet, must swing away from the pool, and must be self-closing and self-latching, with detailed rules for chain-link barriers and for a dwelling wall serving as part of the barrier.
Violations & Fines
Plastering or filling a pool before the required barrier passes inspection, or maintaining a gate that fails to self-close and self-latch, violates the amended California Building Code as adopted by Chino and will fail final inspection.
