The minimum total window or skylight area, measured between stops, for every habitable room shall be at least ten percent of the floor area of such room but if light-obstructing 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 area.
B. Ventilation; Interior Climate Control. 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 interconnection. The total of openable window or skylight area in every habitable room shall be equal to at least fifty percent of the minimum window area size or minimum skylight-type window size, as required in subsection A of this section, except where there is supplied some other device affording adequate ventilation and approved by the appropriate authority.
When facilities for interior climate control (heating, cooling and/or humidity) are integral functions of the structure 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 rental dwelling or rooming units shall be provided.
C. Light and Ventilation Requirements for Bathrooms and Kitchens. Every bathroom and water closet compartment, and nonhabitable room used for food preparation, shall comply with the light and ventilation requirement for habitable rooms contained in subsections A and B of this section, 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 appropriate authority.
D. Electrical Service, Fixtures and Outlets. Where there is usable electric service readily available from power lines which are not more than three hundred feet away from a rental dwelling, every rental dwelling unit and all public and common areas shall be supplied with electric service, outlets and fixtures which shall be properly installed, shall be maintained in good and safe working condition, and shall be connected to a source of electric power in a manner prescribed by the ordinances, rules and regulations of the town.
