Lot area requirements shall be as specified in the applicable zoning district in which a zoning lot is located. No yard or lot existing at the time of passage of this chapter shall be reduced in size or area below the minimum requirements identified within this chapter.
Each lot shall have frontage on a public street at a width satisfying the requirements specified for each zoning district. In the case of a condominium, unified shopping center, cluster development or Planned Unit Development, the entire site shall be considered one zoning lot. No building permit shall be issued for a lot when the only street frontage is on a half-dedicated street.
Except in the case of cluster developments, condominium developments, Planned Unit Developments or traditional neighborhood developments, no more than one principal building shall be located on a zoning lot in any residential district.
Where a lot is bisected by one or more zoning district boundary lines, land in the more restrictive district shall not be included as part of the required yards or minimum lot area for any structures or uses not allowed in that district.
