Unless a greater side yard is required by zoning district regulations, on corner lots, the side yard on the street shall be the same as the requirement for the front, except on corner lots adjacent to a segment of side street upon which no property fronts, said segment being defined as that portion of a street between one street intersection and the next, the minimum side yard shall be 20 feet or the same as the depth of front building setback, whichever is less. This regulation shall not be so interpreted as to reduce the buildable width of a corner lot of record at the time of passage of this chapter to less than 20 feet.
(1998 Code, App. A, § 40-60)
