If any business or establishment required by section 70-28 to possess a special business license is located in whole or in part in a yard, enclosure,
lot or open area, such premises and area shall, so far as reasonably possible, be
kept clean and free from rubbish and similar loose material that might serve as a
harborage for rats, mice or other rodents and all loose metal, or parts or accessories
of automobiles. All other material kept, stored or accumulated in such place shall,
so far as reasonably possible, be neatly and carefully piled in such manner as to
minimize and prevent as far as possible the harborage of rodents and shall be suitably
protected from water and the elements so that there can be, so far as is practicable,
no accumulation of water in any article or thing stored on the premises.
