[Amended 12-16-1981 by Ord. No. 1515; 4-17-1985 by Ord. No. 1674; 10-18-1989 by Ord. No. 1861]
On and after the effective date of this chapter, every person, firm, corporation, partnership or other entity owning or serving as landlord for any building or structure occupied as a home or residence by two or more families, who has agreed to supply or furnish heat shall, during the calendar year of January 1 to December 31 of any year, be required to supply heat to every unit of dwelling space and every bathroom, water closet compartment and every other room therein in any manner inhabited for dwelling by residents by supplying sufficient heat to each resident in sufficient amount to maintain therein a minimum temperature of 68° F. on a constant twenty-four-hour basis whenever the outside temperature falls below 55° F. during any said twenty-four-hour period. Failure to so maintain heat within each dwelling unit shall be a separate violation of this chapter as to each such dwelling unit. Upon his failure to provide heat as herein required, the owner of said unit or units shall be deemed to have violated this chapter. In meeting the aforesaid standards, the owner shall not be responsible for heat loss and the consequent drop in the interior temperature arising out of action by the occupants in leaving windows or doors open to the exterior of the building. The owner shall be obligated to supply required fuel or energy and maintain the heating system in good operating condition so that it can supply heat as required herein notwithstanding any contractual provision seeking to delegate or shift responsibility to the occupant or third person, except that the owner shall not be required to supply fuel or energy for heating purposes to any unit where the occupant thereof agrees in writing to supply heat to his own unit of dwelling space and the said unit is served by its own exclusive heating equipment for which the source of heat can be separately computed and billed.
