(a) Alignment to Existing Building Lines. Where no specific building line is indicated on the Building Zone Map, on a street frontage on one (1) side of a street between two (2) successive intersecting streets but excluding the frontage along the side lines of corner lots, where twenty percent (20%) or more of the aggregate street frontage of the property abutting thereon is occupied by main buildings, the average of the setbacks of the existing buildings within one hundred (100) feet on both sides of any lot shall determine the location of the required front yard line for that lot, except that such front yard line shall not be required to be more than forty (40) feet back of the street line. The location of fences or structures other than a building shall not be a consideration in making such determination.
(b) Alignment to Less Restricted Building Lines. Where a setback building line is required on a lot that adjoins a street frontage along which either no setback building line is required or the required setback building line is nearer to the street, that part of a building within fifty (50) feet of such less restricted frontage may be erected to a building line midway between the required building lines or to a line drawn diagonally from a point fifty (50) feet from the less restricted frontage and on the required setback building line for such lot to the nearest point on the building line of the adjoining less restricted frontage; provided that where such lot is less than fifty (50) feet in width, the diagonal line shall be drawn from the point of intersection of the side lot line and the required setback building line for such lot.
(c) Building Lines on Approved Plats. Whenever the plat of a land subdivision approved by the Planning Commission and on record in the office of the County Recorder shows a setback building line along any frontage for the purpose of creating a front yard or side street yard line, the building line thus shown shall apply along such frontage in place of any other yard line specified in this chapter unless specific building lines shown on the Building Zone Map require a greater setback.
(d) Front Yard Extensions into Other Districts. At the intersection of a residence street with a street in any other use district, where the corner and succeeding lots had been platted before November 5, 1929, to face the residence street and not more than the first three (3) such lots, aggregating a frontage of one hundred fifty (150) feet or less, are included within the less restricted district, the required front yard line for such lots shall be a continuation of the front yard line of the portion of the block included in the Residence District.
(e) Building Lines on Widened Streets. The subsequent widening of a street shall not change the location of a building line established before the street widening except where it would lie within the new street.
