However, if the aggregate width of street walls of a residential building is more than 80 feet or, for abutting buildings if the combined aggregate width of street walls of all such abutting buildings on a zoning lot is more than 80 feet, then two side yards shall be provided, each equal to not less than 10 percent of such aggregate width of street walls. For zoning lots where no such buildings exceed a height of two stories and a basement, side yards need not exceed 15 feet in width.
However, on all corner lots in lower density growth management areas, one side yard shall be at least 20 feet in width.

(b) In the districts indicated, no side yards are required; however, where a building containing residences on an adjacent zoning lot has a side yard, an open area with a minimum width of eight feet and parallel to the side lot line is required along the common side lot line between such buildings. Obstructions permitted pursuant to paragraph (c)(3) of Section 23-461 shall be permitted in such open areas.
