Scope. All properties covered by this article shall meet minimum

(a)
Habitable rooms. Every habitable room shall have at least one window
of approved size facing directly to the outdoors or to a court. The
minimum total window area, measured between stops, for every habitable
room shall be 8% of the floor area of such room, except when artificial
light may be provided in accordance with the provisions of the Construction
Code. Whenever walls or other portions of a structure face a window
of any room and such obstructions 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 nor to a court and shall not be included as contributing

least 4% of the floor area.
(b)
Bathrooms. Every bathroom and water closet compartment shall comply
with the ventilation requirements for habitable spaces as required
by this article; except, that a window shall not be required in bathrooms
or water closet compartments equipped with an approved mechanical
ventilation system. Air exhausted by a mechanical ventilation system
from a bathroom or water closet compartment must be exhausted to the
exterior and may not be recirculated to any space, including the space
from which it is withdrawn.

Cooking appliances. Cooking shall not be permitted in any sleeping
room or dormitory unit, and a cooking appliance shall not be permitted
to be present in a sleeping room or dormitory unit.
(d)
Mechanical ventilation. Where mechanical ventilation is provided
in lieu of the natural ventilation, such mechanical ventilation system
shall be maintained in operation during the occupancy of any structure
or portion thereof. When part of the air provided by a mechanical
ventilation system is recirculated, the portion or volume of air recirculated
shall not be recirculated to a different residential space or occupancy
of dissimilar use from which it is withdrawn.
(e)
Clothes dryer exhaust. Clothes dryer venting systems shall be independent
of all other systems and shall be vented in accordance with the manufacturer's
recommendations. All clothes dryer vent ducts must be constructed
of a metallic duct material.

demonstrates in writing to the Department of Community and Neighborhood
Services on or before December 31, 2014, that the unit was so occupied.
(3)

annual basic housing permit for that dwelling unit is revoked or expires
at any time after September 1, 2014, and is not renewed for at least
