   No person shall occupy as owner/occupant, or let to another for occupancy, any dwelling, multi- family dwelling, dwelling unit, rooming house, rooming unit, or portion thereof, for the purpose of living therein which does not comply with the following requirements.
   (A)   Free from dampness.  In every dwelling, multi-family dwelling, dwelling unit, rooming house, and rooming unit, cellars, basements and crawl spaces shall be maintained reasonably free from dampness to prevent conditions conductive to decay or deterioration of the structure as required by the building code.
   (B)   Structural members.  The supporting structural members of every dwelling and multi-family dwelling used for human habitation shall be maintained structurally sound; showing no evidence of deterioration which would render them incapable of carrying the imposed loads in accordance with the provisions of the building code.
   (C)   Interior stairs and railings.  Stairs shall be provided in every dwelling, multi-family dwelling, rooming and boarding house as required by the building code:
      (1)   Maintained in good repair.  All interior stairs of every structure used for human habitation shall be maintained in sound condition and good repair by replacing treads and risers that evidence excessive wear or are broken, warped or loose.  Every inside stair shall be so constructed and maintained as to be safe to use and capable of supporting a load as required by the provisions of the building code.
      (2)   Handrails.  Every stairwell and every flight of stairs, which is more than two risers high, shall have handrails or railings located in accordance with the provisions of the building code.  Every handrail or railing shall be firmly fastened and must be maintained in good condition.  Properly balustraded railings, capable of bearing normally imposed loads as required by the building code, shall be placed on the open portions of the stairs, balconies, landings and stairwells.
   (D)   Bathroom floors.  Every toilet and bathroom floor surface shall be constructed and maintained so as to be substantially impervious to water and so as to permit such floor to be easily kept in a clean and sanitary condition.
   (E)   Sanitation.  The interior of every dwelling and multi-family dwelling used for human habitation shall be maintained in a clean and sanitary condition free from any accumulation of rubbish or garbage.  Rubbish, garbage, and other refuse shall be properly kept inside temporary storage facilities as required under §§ 151.040(D) and (E) of this code.
   (F)   Insect and rodent harborage.  Buildings used for human habitation 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 reinfestation.
      (1)   Extermination from buildings.  Every owner of a dwelling or multi-family 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.
      (2)   Extermination from single dwelling units.  The occupant of a dwelling unit in a dwelling or multi-family 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.
      (3)   Responsibility of owner.  Notwithstanding the foregoing provisions, whenever infestation of rodents is caused by failure of the owner to maintain any dwelling or multi-family dwelling in a rodent-proof condition, extermination of such rodents shall be the responsibility of the owner.
