Where a building line is shown on the Zone Map as an existing alignment line, the alignment of buildings existing along a street frontage shall determine the building line. On any street frontage in a U-1 District where no building line is designated on the Map, the location of the building line shall be as follows:
(a) On a street frontage on either side of a street between two intersecting streets, but excluding the frontage along the side line of a corner lot, the distance of the building line back from the street line shall be twenty percent of the average or normal depth of the lots having their front lines along such street frontage, but such distance back from the street line need not be more than forty feet. Where, in any portion of such street frontage, there are lots of markedly less depth than the normal, the City Planning Commission, in defining and applying this building line regulation, may, when in its opinion the general purpose and intent of this section will be better served thereby, divide such street frontage into sections for the application of such twenty percent building line requirement. For the purpose of this subsection, the term "lot" includes unimproved parcels in separate ownership and unimproved lots or parcels in subdivisions of land.
(b) In a U-1 District, along the side line of a corner lot the distance of the building line back from the street line shall be twenty percent of the average width of such lot, but such distance back from the street line need not be more than twenty feet.
