(A)   No person, firm or corporation in possession of land within the city, either as owner, purchaser under contract, lessee, tenant or licensee, upon which is situated a swimming pool or other outside body of water designed or used for swimming, dipping or immersion purposes by men, women or children, of a minimum depth of 18 inches shall fail to maintain on the lot or premises upon which such pool or body of water is located and completely surrounding such pool or body of water, a fence or wall not less than six feet nor more than eight feet in height, with openings, holes or gaps therein no larger than four inches in any dimension; prohibited, however, that if a picket fence is erected or maintained, the horizontal dimension shall not exceed four inches; provided, further, that the wall of a building located on the same property as the swimming pool may be used as a part of such enclosure. The height of the fence or wall shall be measured from the grade of the property upon which the swimming pool is located.  If there is a grade differential between the property upon which the swimming pool is located and any adjacent property, the height of the fence or wall shall be measured from the higher of the two properties.
   (B)   All gates or doors opening through such enclosure shall be at the same height of the enclosure and shall be equipped with a self-closing and self-latching device designed to keep, and capable of keeping, such door or gate securely closed at all times when not in actual use; provided, however, that the door of any building occupied by human beings and forming any part of the enclosure hereinabove required need not be so equipped.
