Where in this code the obligation for observance is not otherwise clearly designated, the respective responsibilities of owner, operator and occupants are as follows:
A. 
Every occupant of a dwelling, dwelling unit or rooming unit shall maintain in a clean and sanitary condition that part of the dwelling, dwelling unit and yard which he occupies and controls.
B. 
Every owner or operator of a two-unit dwelling, multiunit dwelling or rooming house shall maintain in a clean and sanitary condition, the shared, public, owner and operator-controlled areas of the dwelling and yard.
Every occupant of a dwelling or dwelling unit shall dispose of all rubbish, ashes, garbage and other organic waste by placing it in containers which are watertight, rodent-proof and are equipped with tight-fitting covers. Every occupant shall provide such facilities for his own unit and shall maintain them. The owner or operator of a multiunit dwelling shall furnish common storage of disposal facilities and shall maintain them. Every owner or operator of a rooming house shall dispose of all rubbish and garbage in furnished common storage. Containers as described above are the minimum acceptable standard for common storage.
A. 
Every occupant of a dwelling containing a single dwelling unit shall be responsible for the extermination of any insects, rodents or other pests in it or in the yard. In a two-unit dwelling or a multiunit dwelling, the occupant shall be responsible for such extermination whenever his dwelling unit is the only one infested. When, however, infestation is caused by failure of the owner or operator to maintain a dwelling in a rodent-proof or substantially insect-proof condition, extermination shall be the responsibility of the owner or operator.
B. 
Every owner or operator shall be responsible for extermination of any insects, rodents or other pests whenever infestation exists in two or more of the dwelling units in any dwelling or in the shared or public area of any two-unit dwellings or any multiunit dwelling.
C. 
Every owner or operator of a rooming house shall be responsible for the extermination of any insects, rodents or other pests in it or in the yard.
