§ 30-45. Extermination of pests.

A. 

Every occupant of a dwelling containing a single-dwelling unit shall be responsible for the extermination of any insects, rodents or other pests therein or on the premises, and every occupant of a dwelling unit or rooming unit in a dwelling containing more than one such unit shall be responsible for such extermination whenever his unit is the only unit within the dwelling that is infested. Notwithstanding the foregoing provisions of this section, whenever infestation is caused by failure of the owner to maintain a single-family dwelling let to another person or a dwelling unit or rooming unit in a dwelling containing more than one such unit (including but not limited to a unit occupied by the owner) in a ratproof or reasonably insectproof condition, extermination shall be the responsibility of the owner. Whenever infestation exists in two or more of the dwelling units or rooming units in any dwelling or in the shared or common parts of any dwelling containing two or more units, extermination thereof shall be the responsibility of the owner.

B. 

No owner or occupant of a dwelling or dwelling unit shall store, place or allow to accumulate any materials which may serve as food for rats in a site accessible to rats. No owner of a dwelling shall permit accumulation of rubbish, boxes, lumber, scrap metal or any other materials in such a manner that may provide a rat harborage in a dwelling or about the shared or public areas of a dwelling or its premises. Materials stored by the owner or permitted to be stored by the owner shall be stacked neatly in piles elevated at least 18 inches above the ground floor. No occupants of a dwelling or dwelling unit shall accumulate rubbish, boxes, lumber, scrap metal or any other materials in such a manner that may provide a rat harborage in or about any dwelling or dwelling unit. Stored materials shall be stacked neatly in piles elevated at least 18 inches above the ground or floor.
