   (i)   Interior lots shall have a side yard on each side of any building thereon.
   (aa)    One-story dwellings shall have side yards of five (5') feet or more, and the sum of the side yards to the nearest foot shall equal or exceed fifteen (15%) percent of the width of the lot, if the lot is wider than seventy (70') feet, or ten (10') feet or more where the width of the lot is seventy (70') feet or less.
   (ab)    Two (2) story dwellings shall have a side yard of five (5') feet or more, except that any side yard adjacent to a two (2) story dwelling wall shall be ten (10%) percent of the width of the lot or more, measured to the nearest foot, and two (2) story walls with windows shall have a minimum side yard of ten (10') feet.
   (ac)    In cases where the side yard requirements exceed five (5') feet on one side and ten (10') feet on the other side, the provisions of subsections (aa) and (ab) of this subsection shall not apply to those tracts for which a tentative map has been approved subsequent to December 7, 1961, and prior to January 2, 1964, and for which a final map is recorded prior to January 2, 1965.
   (ii)   Corner lots shall have the side yards prescribed for interior lots except in the case of reverse-corner lots.  Each reverse-corner lot shall have a side yard on the street side of such lot of not less than ten (10') feet.
   (2)   In the R-3 Zone interior lots shall have a side yard on each side of any building thereon.

The decision-making body may modify the additional side yard setback requirements when necessary to allow buildings in excess of twenty-five (25') feet in order to accommodate the housing need for lower income households specified in the Housing Element of the Thousand Oaks General Plan.
