An existing detached single-family dwelling that is incorporated into a cottage housing development as a residence and is nonconforming with respect to the standards of this section shall be permitted to remain on a site used for a cottage housing development and shall count as one of the allowed units. However, the extent of the noncompliance may not be increased unless the proposed change is determined by the Planning Director to be consistent in character, scale and design with the cottage housing development. An existing dwelling may be replaced with cottage units consistent with this section. (Ord. 1263, 12-29-2011)
