Every habitable room shall have at least one
window or skylight facing directly to the outdoors. The minimum aggregate
glass area available for unobstructed light for every habitable room
shall be not less than 10% of the floor space of such room.
Whenever walls or other portions of structures face a window of a habitable room in any dwelling and such 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 a window shall not be deemed to face directly to the outdoors and shall not be included as contributing to the minimum total window area required by § 247-82.
Every habitable room shall have at least one window or skylight which can easily be opened, or shall have such other device as will adequately ventilate the room. The total openable window area in every habitable room shall be equal to at least 50% of the minimum aggregate glass area required in § 247-82, except where there is supplied some other approved device affording adequate ventilation.
Every bathroom and toilet room or compartment shall comply with the light and ventilation requirements for habitable rooms contained in §§ 247-82, 247-83 and 247-84, except that in no case shall the minimum glass area of such window or skylight be less than three square feet, provided that no window or skylight shall be required in any bathroom or toilet compartment equipped with an approved ventilation system.
From May 1 to October 1 of each year, every
opening, except bulkheads, used for ingress or egress from a dwelling
or dwelling unit directly to or from outdoor space shall be supplied
with either a self-closing device or self-closing screen door. Every
window of every habitable room, bathroom and toilet room or compartment
and every other window or opening below the sixth floor from the dwelling
or dwelling unit to outdoor space while in use for ventilation shall
be equipped with approved screening which shall be provided by the
occupant, when not supplied by the owner.
Every cellar and basement shall have at least
two vents or windows opening directly to the outside air sufficient
to prevent mildew or structural deterioration and properly equipped
with approved screening, except where there is supplied some other
approved device affording adequate ventilation.
Every habitable room shall be supplied with
at least two separate electric convenience outlets, or one such convenience
outlet and one separate electric light fixture. Every toilet room
or compartment, bathroom, laundry room, furnace room, stairway and
communicating corridor shall be supplied with at least one electric
light fixture. Every such outlet and fixture shall be properly installed,
shall be maintained in good and safe working condition and shall be
properly connected to the source of electric power.
Every public hall and common stairway used primarily
for egress or ingress in connection with two or more dwelling units
shall be supplied with a proper amount of natural or electric light
at all times, provided that such public halls and common stairways
in structures containing not more than three dwelling units shall
be deemed to have fulfilled such requirement if they are properly
supplied with conveniently located switches, controlling an adequate
electric lighting system which may be turned on when needed; provided
further, that all common stairways not used primarily for egress or
ingress in all dwellings shall be properly supplied with such switches.
