No person in charge of or in control of any premises, whether as owner, lessee, tenant, occupant or otherwise, shall allow any partially dismantled, wrecked, junked, discarded or otherwise nonoperating and unlicensed motor vehicle, machinery, farm implement, equipment and/or personal property of any kind, which is no longer safely usable for the purposes for which it was manufactured, to remain on such property longer than twenty eight (28) days, unless such vehicle, equipment or other property, is maintained in an enclosed building or so located within a fenced or screened enclosure of at least six feet (6') in height, in accordance with, and as defined by, the zoning ordinance and building codes of the city, such that the materials are not readily visible from any public place or from any surrounding private property. Allowing such materials to remain unenclosed or unscreened shall constitute a nuisance. This section shall not apply with regard to any vehicle, equipment or other personal property on the premises of a business enterprise operated in a lawful place, other than in a residential district, and operated in a lawful manner, when the keeping or maintenance of such vehicle, equipment or other damaged and abandoned personal property is necessary to the operation of such business enterprise and is not in violation of other provisions of law.
