A. Scope. This section shall apply to yards and courts having required windows opening therein.
B. Yards. Every yard shall be not less than 3 feet in width for one-story and two-story buildings. For buildings more than two stories in height the minimum width of the yard shall be increased at the rate of 1 foot for each additional story. Where yards completely surround the building, the required width may be reduced by 1 foot. For buildings exceeding 14 stories in height, the required width of yard shall be computed on the basis of 14 stories.
C. Courts. Every court shall be not less than 3 feet in width. Courts having windows opening on opposite sides shall be not less than 6 feet in width. Courts bounded on three or more sides by the walls of the building shall be not less than 10 feet in length unless bounded on one end by a public way or yard. For buildings more than two stories in height the court shall be increased 1 foot in width and 2 feet in length for each additional story. For buildings exceeding 14 stories in height, the required dimensions shall be computed on the basis of 14 stories.
Adequate access shall be provided to the bottom of all courts for cleaning purposes. Every court more than two stories in height shall be provided with a horizontal air intake at the bottom not less than 10 square feet in area and leading to the exterior of the building unless abutting a yard or public way. The construction of the air intake shall be as required for the court walls of the building, but in no case shall be less than one-hour fire-resistive.
