Single-family attached and/or single-family detached dwelling developments existing at the time the ordinance codified in this chapter became effective may be subdivided into individual unit lots. The development as a whole shall meet development standards applicable at the time the development was approved. As a result of the unit lot subdivision, development on individual unit lots may be nonconforming as to some or all of the development standards of Chapters 19.24 through 19.27 EMC and this title as applied to the individual unit lot, except that any private open space for individual dwelling units shall be provided on the same lot as the dwelling unit it serves. The review authority shall have the authority to add reasonable conditions of approval that would make the development more closely conform to current landscaping and/or design standards. (Ord. 3774-20 § 5(O) (Exh. 3), 2020.)
