Buildings shall be kept free from insect and rodent infestation, and where insects or rodents are found, they shall be promptly exterminated by acceptable processes which will not be injurious to human health. After extermination, proper precautions shall be taken to prevent re-infestation.

    A.    Extermination from Buildings. Every owner of a dwelling or multifamily dwelling shall be responsible for the extermination of insects, rodents, vermin or other pests whenever infestation exists in two or more of the dwelling units, or in the shared or public parts of the structure.

    B.    Extermination from Single Dwelling Units. The occupant of a dwelling unit in a dwelling or multifamily dwelling shall be responsible for such extermination within the unit occupied by him whenever his dwelling unit is the only unit in the building that is infested.

    C.    Responsibility of Owner. Notwithstanding the foregoing provisions, whenever infestation of rodents is caused by failure of the owner to maintain any dwelling or multifamily dwelling in a rodent-proof condition, extermination of such rodents shall be the responsibility of the owner. (Prior code § 17-1-19)
