Every private swimming pool shall be completely surrounded by a fence or wall not less than four (4) feet in height which shall be of a type which precludes passage through or under and is not readily climbable by small children. This shall not mean an additional fence within a completely fenced yard, provided, the fence meets the stated minimum requirement. All gates shall be equipped with a latch which is not readily operated by small children.
The main building, or any accessory structure, on the site may form part of the enclosure. The sides of above-ground pools are acceptable as integral barriers, provided, that the sides extend not less than four (4) feet above the outside ground at all points, and provided further, that access steps or ladders are capable of being rendered inaccessible by being removed or raised more than four (4) feet above the outside grade.
