All swimming pools or similar pools shall be completely enclosed by a fence to prevent access to the pool from other than from within the building. Such fence shall be a minimum of five feet in height, except that existing fences, installed under previous codes that are a minimum of four feet six inches in height may remain. Fences shall be constructed so as not to provide openings or projections or other facilities that would make such fence conducive to climbing by a child. If vertical members are supported by top and bottom rails connected to posts, the space between such vertical members shall not exceed five inches.
Access to the pool from outside the fence shall be by way of a gate. Such gate shall be equipped with a self-latching device which is not accessible from the outside of the fence and which will keep the gate closed and latched at all times. (Prior code § 9.16.521)
