(a) Intent. A projection is the part or feature of a building that extends outside of the enclosing surfaces into a yard. It is desirable that such features extend into yards in order to make the enclosed space more usable; however, it is intended that these projections into required yards shall be regulated so that they will not substantially interfere with an adjacent building's reception of sun, light, and air. Required front, side, or rear yards shall be open and unobstructed from the ground to the sky except for the following:
(b) Architectural Features. A belt course, balcony, bay window, cornice, gutter, chimney, or solid overhang may project not more than 3-1/2 feet into a required front yard, and not more than 2-1/2 feet into a required side yard, provided the projection is not less than 2 feet from any side lot line, and the minimum distance from the side lot line shall be increased 2 inches for each foot that the feature exceeds 10 feet in width.
(c) Entrance Features.
(1) A platform landing, steps, terrace, or other features not extending above the first floor level of a building, may project not more than 8 feet into a required front yard, and not more than 3 feet into a required side yard, provided the projection is at least 2 feet from any side lot line.
(2) A fire escape or enclosed stairway and landing leading to the second floor of a converted building may project 4 feet into a required side yard or rear yard, provided the projection is at least 3 feet from any side lot line, and provided it is approved by the Commission.
(d) Shelters.
(1) An enclosed entry, not exceeding 10 feet in width or one story in height, may project not more than 5 feet into a required front yard. A roofed, but unenclosed, porch or entrance hood may project into a required front yard not more than 8 feet, and if not exceeding 6 feet in width, may project into a required side yard not more than 3 feet, provided the projection is at least 2 feet from any side lot line.
(2) An enclosed porch, carport, and other similar structure or part thereof, shall not project into a required yard; except that an unenclosed porch lawfully in existence on January 1, 1957, may be enclosed, even though it does project into the required yard.
(e) Shading Devices.
(1) A metal or plastic awning which is not removed seasonally, may project into a required front or side yard, providing such projection is at least 2 feet from any side lot line.
(2) A trellis, louvers, and similar horizontal, open, shading devices may project into a required front yard not more than 8 feet, and may project into a side yard provided the projection is at least 2 feet from any side lot line.
