Wherever walls or other portions of any structure face a window of any such rooms, and where such light-obstructing structure is located less than three (3) feet from the window and extends to a level above that of the ceiling of the room such 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.

Each window shall be not less than three (3) square feet in area.

5.02.
