18.144.160: SIDE YARD:
   A.   The side yard provisions of the zone in which the site is located shall apply to all properties in the planned development which abut property not a part of the development.
   B.   For the remainder of the development, the side yard(s) for a residence or a group of residences may be modified as follows:
      1.   For a single-family detached residence on a separate lot, the side yard(s) in a planned residential development may be reduced below that required by the underlying zone district, subject to approval by the planning commission pursuant to the conditional use permit. Where the side yard(s) does not permit the parking of recreational vehicles, then the CC&Rs for the project shall prohibit the parking of such vehicles on separate lots within the development. No window or door openings are permitted on the zero setback line.
      2.   For attached single-family residences or patio houses and townhouses, both interior side yards between structures in a series or group may be reduced to zero, provided the exterior side yards of the series or group are set back a distance not less than ten feet (10') for each story of height of each building series or group. No window or door openings are permitted on the zero setback line. (Ord. 2459 § 1, 2000: Ord. 1000 § 52.54(G), 1955)
