§14-103. Zoning Maps and Districts.


(1) Districts. The City shall be divided into the classes of districts described in this Title. The districts are located and bounded as shown on the zoning maps adopted by the Ordinance of August 10, 1933, as amended. These maps are hereby further amended and, as amended, are hereby ratified, confirmed, and made a part of this Title.

(2) Boundaries of Districts. Where uncertainty exists with respect to the boundaries of the various districts, as shown on any zoning map, the following rules apply:

(a) The district boundaries are street lines unless otherwise shown; and where the designation on the zoning maps indicates a boundary approximately upon a street line, such street line shall be construed to be the boundary;

(b) Where the district boundaries are not shown to be street lines, the district boundaries shall be construed to be lot lines; and where the designations on the zoning maps indicates a district boundary approximately upon lot lines, said lot lines shall be construed to be the boundary;

(c) In undivided property, the district boundary lines on the zoning maps shall be determined by measurement according to the scale of the maps;

(d) No district boundary shown on the zoning maps shall be construed as extending the authority of the Department of Licenses and Inspections beyond the low water mark on any navigable stream;

(e) Where a street is stricken from the City plan or where a railroad right-of-way is abandoned, the zoning boundaries of the abutting land shall be extended to the center line of said street or right-of-way.

(3) Multiple Districts or Provisions. When the boundaries of various districts as shown on the zoning map are established so that a single property has more than one zoning district designation, or is subject to various controls or requirements as established in this Title, the most restrictive district, requirement, or control shall apply; provided, when a zoning designation on a split- zoned property covers twenty percent or less of the area of the parcel, this designation shall not apply in terms of use control or zoning control on the entire lot, but shall control only that portion of the lot so zoned.[10]

(4) Property Owned, Leased or Operated by Public Agencies.[11] Property leased or operated by the Commonwealth of Pennsylvania or the United States, and property owned, leased or operated by the City of Philadelphia, or any other public or governmental body or agency, shall be subject to the terms of this Title, as follows:

(a) Where such public or governmental uses are specifically listed, they shall be governed as indicated;

(b) Where such public or governmental uses are not specifically listed, they shall be permitted only is districts permitting private uses of a similar or substantially similar nature;

(c) Property owned by the Commonwealth of Pennsylvania or the United States shall be exempt from the provisions of this Title only to the extent that said property may not be constitutionally regulated by this City.
