Every person in possession of land within the city upon which is situated a swimming pool, either as owner, purchaser under contract, lessee, tenant, or licensee, shall at all times maintain on the lot or premises upon which the pool is located, a fence or solid structure, completely surrounding such pool, lot or premises, not less than five feet in height with no opening therein (other than doors or gates) larger than six inches square. All gates or doors opening through such enclosures shall be equipped with a self-closing and/or self-latching device designed to keep, and capable of keeping, the door or gate securely closed at all times when not in actual use; provided, however, that the door of any dwelling occupied by human beings and forming any part of the enclosure required need not be so equipped.
