(a) Every habitable room shall have one or more windows opening directly on a street or on a court or yard or shall be provided with an approved means of mechanical ventilation as prescribed in this section.
(b) Windows shall have an area between stop beads of not less than 10% of the floor area of the room served by them and in addition shall not be less than 12 square feet in area for habitable rooms and public halls and eight square feet for bathrooms and similar rooms, provided that where a water closet occupies a separate compartment 40 square feet or less in area, the minimum requirement shall be four square feet. At least 50% of the required window area shall be arranged to open for ventilation. Where 100% of the window area is arranged to open for ventilation, the window area required for separate water closet compartments 40 square feet or less in area may be reduced to not less than three square feet. In lieu of windows in habitable rooms, glass area in exterior doors may be accepted for 100% of the light requirements, but not more than 50% of the ventilation requirements.
(c) The area of skylights permitted by this section shall be not less than that required for windows which they replace. At least 50% of the required area shall be made available as clear ventilating area by means of movable sash, louvers or similar devices.
(d) When mechanical ventilation is required, or is permitted as an alternative, the system shall be designed and constructed in accordance with generally accepted good practice to provide the necessary changes in air, but not less than one cubic foot of air per minute shall be provided for each square foot of floor area in any case. Such system shall be kept in continuous operation at all times during the normal occupancy of the building.
(e) All dwellings and dwelling units shall be supplied with electric service of at least two separate and remote floor or wall-type electrical convenience outlets in every habitable room. Every public hall, water closet, compartment, bathroom, laundry room and furnace room shall contain at least one electric light fixture. The electric service in multiple dwellings must be installed with the approval of underwriters insuring properties in the township. When artificial lighting is required, all habitable rooms shall have sufficient light to produce an intensity of not less than 15 footcandles at 30 inches from the floor.
(f) All dwelling and dwelling units shall have heating facilities which shall be properly installed, safely maintained and in good working condition. All habitable rooms, bathrooms and toilet rooms shall be heated to a temperature of at least 68°F at a distance four feet above the floor level and not closer than three feet from an outside wall, window or door at all times.
(g) Every public hall and public stairway in a multiple dwelling shall be lighted by means of electrically lighted fixtures. Such lighting fixtures shall provide two footcandles of light in every part of the public hall and public stairway at all times. However, such electrical lighting may be omitted from sunrise to sunset where there are windows or skylights opening directly to the outside and where the total window or skylight area provides two footcandles of natural light to all parts of each such public hall or stairway.
(h) All dwellings and dwelling units shall be furnished with screens for every door and window opening directly to outdoor space. In multiple dwellings, it shall be the responsibility of the operator to furnish and hang the screens. Screens shall have a mesh of not less than No. 14 and shall be hung not later than June 1 and removed no sooner than November 1 of each year. Screens shall not be required during such period in rooms deemed by the Board of Health to be located high enough in the upper stories of buildings as to be free from insects and in rooms located in areas which are deemed by the Board to have so few insects as to render screens unnecessary.
