(a) On corner lots in the R-1, R-2 and R-3 Districts, there must be a front and rear yard having a depth as described and set forth herein Section 4.2. Building on corner lots where interior lots have been platted on side streets shall provide a side yard adjacent to the side street of not less than 15 feet, provided this regulation may not be so interpreted as to reduce the buildable width of a corner lot of record at the time of passage of Ordinance No. 3466 to less than 65 per cent of the total width of such lot, and provided further that the minimum side yard regulations in Section 4.2 must be observed. Accessory buildings on corner lots, where interior lots have been platted on side streets, shall not project beyond the front yard line established on the side street, provided this regulation shall not reduce the buildable width to less than 20 feet.

(b) Where a frontage is divided among districts with different front yard requirements the deepest front yard shall apply to the entire frontage.
