19.22 Split Zoning
Where a Zoning District boundary line runs approximately parallel to a street and divides a lot with street frontage in the less restricted Zoning District, the provisions of this chapter covering the less restricted portion of the lot may extend to the entire lot, but in no case more than 25 feet of such Zoning District boundary line. Where such Zoning District boundary line divides a lot with street frontage in a more restricted zone, the provisions of this Subchapter covering the more restricted portion of such lot shall extend to the entire lot. Where a Zoning District boundary line divides a lot and such line is normal or approximately normal to the street upon which the lot fronts, the provisions of this Subchapter covering the less or more restricted portion of such lot may be extended to the entire lot, but in no case more than 25 feet from such Zoning District boundary line.
