No person shall occupy as owner or occupant or let to another for occupancy any dwelling or dwelling unit, for the purpose of living therein, which does not comply with the requirements of this section.
(A) Window or skylight; daylight. Every habitable room shall have at least one window or skylight facing directly outdoors provided that if connected to a room or area used seasonally (e.g., porch) then adequate daylight must be possible through this inter-connection. The minimum total window or skylight area, measured between stops, for every habitable room shall be at least 10% of the floor area of such room but if light-obstruction structures are located less than three feet from the window and extend to a level above that of the ceiling of the room, such window shall not be deemed to face directly to the outdoors and shall not be included as contributing to the required minimum total window area.
(B) Window or skylight; ventilation. Every habitable room shall have at least one window or skylight facing directly outdoors which can be opened easily, or such other device as will ventilate the room adequately, provided that if connected to a room or area used seasonally then adequate ventilation must be possible through this inter-connection. The total of openable window or skylight area in every habitable room shall be equal to at least 45% of the minimum window area size or minimum skylight window size, as required in division (A) above, except where there is supplied some other device affording adequate ventilation and approved by the Police and Public Safety/Health and Property Chairperson.
(C) Climate control devices. When facilities for interior control (heating, cooling and/or humidity) are integral functions of structures containing dwelling units or rooming units, such facilities shall be maintained and operated in a continuous manner and in accordance with the designed capacity of the installed equipment. During instances when the integral equipment is inoperative because of power or mechanical failure, alternative provisions for fresh air ventilation of each dwelling or rooming unit shall be provided.
(D) Ventilation in bathroom and food preparation room. Every bathroom and water closet compartment, and non-habitable room used for food preparation, shall comply with the light and ventilation requirements for habitable rooms contained in divisions (A) and (B), except that no window or skylight shall be required in such rooms if they are equipped with a ventilation system in working condition which is approved by the Police and Public Safety/Health and Property Chairperson.
