(A) Except as otherwise specified in this subchapter, all improvements on a lot shall be subject to and in compliance with the yard and setback requirements in Table IV-2 of this chapter.
(B) Visibility triangle at intersections. On corner lots, no obstruction greater than five inches in diameter or higher than 30 inches above the centerline grade of the intersecting streets, shall be permitted in the following described triangle area of any required front yard. The visibility triangle shall be as follows: from the corner property pin at the intersection of the two street right-of-way lines, measure along the property lines a distance of 20 feet to form the legs of the triangle, then connect those two end points to close the triangle. In addition, at any intersection involving a collector or arterial street as designated in the City's Comprehensive Plan, the visibility triangle shall increase to 30 feet. This requirement will be waived only if the subject intersection is signalized to assure safety.
(C) Front yards for corner lots and through lots. For any corner lot or through lot, both frontages shall comply with the front yard requirement of the district in which it is located, except that neither the buildable width nor depth of the lot shall be reduced to less than 30 feet. The rear lot line of a rectangular shaped lot with frontage on two intersecting streets shall be that line which is parallel to the narrower of the two street frontages.
(D) Location of required yards. All yards and open spaces required by the provisions of this chapter shall be located on the same lot as the principal building or use. No portion of a lot, used to document compliance with the provisions of this chapter, shall be used to satisfy minimum bulk requirements for any other lot, either through change of ownership or other means, if the portion to be reallocated would cause the original lot to fall below the minimum requirements of this chapter.
(E) Yards for common lot line dwellings. Each lot which contains a common lot line dwelling unit shall be considered separate and independent from adjoining common lot line dwelling units for the purpose of determining front and rear yards. No side yard setback shall be required for interior lots or for the interior portion of end lots for common lot line dwellings.
(F) Average setback. In all residential zoning districts, the front yard may be reduced to a setback equal to the average alignment of existing principal buildings on the same side of the street upon meeting the following conditions:
(1) 51% or more of the lots on the same side of the street, within the same block, are improved with principal buildings;
(2) 75% of the principal buildings extend into the required front yard;
(3) No principal building shall project beyond the average alignment of existing principal buildings which are located on the same side of the street, within the same block, and within 200 feet of the proposed principal building;
(4) No principal building shall project beyond the shortest depth of existing front yards on the lots abutting on each side.
