(A) Every habitable room shall have at least one window or skylight facing directly to the outdoors. The minimum total window area, measured between stops, for every habitable room shall be 10% of the floor area of the room. Whenever walls or other portions of structures face a window of any such room and the 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 a 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. Whenever the only window in a room is a skylight type window in the top of such room, the total window area of such skylight shall equal at least 10% of the total floor area of such room.
(B) Every habitable room shall have at least one window or skylight which can easily be opened, or such other device as will adequately ventilate the room. The total of openable window area in every habitable room shall be equal to at least 45% of the minimum window area size or minimum skylight type window size, as required in division (A) above, except where there is supplied some other device affording adequate ventilation and approved by the Building Inspector and/or Health Officer.
(C) Every bathroom and water closet compartment shall comply with the light and ventilation requirements for habitable rooms contained in division (A) and (B) above, except that no window or skylight shall be required in adequately ventilated bathrooms and water closet compartments equipped with a ventilation system which is kept in operation when occupied and approved by the Building Inspector and/or Health Officer.
(D) Where there is electric service available from power lines which are not more than 300 feet away from a dwelling, every habitable room of such dwelling shall contain at least two separate floor or wall-type electric convenience outlets, or one such convenience outlet; and every water closet compartment, bathroom, laundry room, furnace room and public hall shall contain at least one supplied ceiling or wall-type electric light fixture. Every such outlet and fixture shall be properly installed, shall be maintained in good and safe working condition and shall be connected to the source of electric power in a safe manner.
(E) Every dwelling shall have heating facilities which are properly installed, are maintained in safe and good working condition, and are capable of safely and adequately heating all habitable rooms, bathrooms, and water closet compartments in every dwelling unit located therein to a temperature of a least 65 degrees Fahrenheit, at a distance of three feet above floor level, under ordinary minimum winter conditions.
(F) Every public hall stairway in every multiple dwelling containing five or more dwelling units shall be adequately lighted at all times. Every public hall and stairway in structures devoted solely to dwelling occupancy and containing not more than four dwelling units may be supplied with conveniently located light switches, controlling an adequate lighting system which may be turned on when needed, instead of full-time lighting.
(G) Every basement or cellar window used or intended to be used for ventilation, and every other opening to a basement which might provide an entry for rodents, shall be supplied with a screen or such other device as will effectively prevent their entrance.
