(.1)   Properties Bounded by Two Streets.
When a property is bounded by two streets:
(.a)   That constitute a corner, one of the remaining lot lines shall be deemed a side and the other remaining lot line shall be deemed a rear. Where the determination of side and rear lot lines is necessary for L&I to approve or deny a zoning permit application, the Commission shall determine the side and rear lot lines based on the orientation of the lot, orientation of the primary structure, orientation of the structures on adjacent lots, orientation of structures with frontage on the same blockface, the street type designation of the bounding streets, or any additional criteria stated in the regulations of the Commission for the purposes of clarifying or implementing this determination. 558
(.b)   That are opposite each other, the remaining two property lines shall be considered sides and the side yard requirements of the zoning district shall apply to the remaining lot lines. The rear yard requirements of the zoning district shall not apply.
(.2)   Properties Bounded by Three or More Streets.
When a property is bounded by three or more streets, the remaining lot line shall be considered a rear. The rear yard requirements of the zoning district shall apply to that lot line, except a rear yard is not required for attached buildings or semi-detached buildings but the requirements for lot coverage and open space remain the same. The side yard requirements of the zoning district shall not apply.
(.3)   Properties Completely Surrounded By Streets.
When a property is completely surrounded by streets, only the front yard requirements of the zoning district shall apply.
(.4)   Primary Frontage.
(.a)   When necessary to apply certain provisions of this Zoning Code, properties bounded by two or more streets shall have at least one street frontage designated as a primary frontage by the Commission.
(.b)   The Commission shall determine which street frontages shall be designated as a primary frontage based on the orientation of the primary structure, the orientation of the structures on adjacent lots, the orientation of other structures with frontage on same block face, the street type designation of the bounding street, or any additional criteria stated in the regulations of the Commission for the purposes of clarifying or implementing this determination.
(.c)   The primary frontage designation shall only apply to those provisions of this Zoning Code where specified, otherwise the front yard and front setback requirements of this Zoning Code shall apply.
(e)   Using the Dimensional Tables. 559
All primary and accessory structures are subject to the dimensional standards set forth in the following tables.
(.1)   "Y" indicates that the building type is permitted, subject to compliance with the dimensional standards set forth in the table.
(.2)   "N" indicates that the building type is prohibited.
(.3)   "S" indicates that the building type may be allowed if reviewed and approved in accordance with the special exception procedures of § 14-303(7) (Special Exception Approval).
(.4)   A number in brackets (e.g., "[2]") is a reference to a table note that contains supplemental standards or other explanatory information. Table notes are found in § 14-701(2)(b) (Notes for Table 14-701-1); § 14-701(2)(c) (Notes for Table 14-701-2); § 14-701(3)(a) (Notes for Table 14-701-3); and § 14-701(4)(a) (Notes for Table 14-701-4).
