The regulations specified in this chapter shall
be subject to the following exceptions, modifications, and interpretations.
Where the average setback line of at least two
existing buildings on lots which are on the same side of the street
or road and within 200 feet of the lot in question is less than the
minimum setback prescribed by this chapter, the minimum setback line
shall be the average setback line of all buildings within 200 feet
of the proposed building. However, in no case shall the setback line
be less than 35 feet from the center line of any abutting road or
street.
The Board may authorize, upon appeal, in accordance with §
180-105 variances from height, lot area, lot width, yard regulations, parking space requirements, sign regulations, and distance requirements specified in §
180-16. The Board may grant such variance only in cases where the strict compliance with the terms of this chapter would result in practical difficulty and unreasonable hardship, and only if in strict harmony with the spirit and intent of such regulations and only in a manner so as to grant relief without substantial injury to public health, safety, and general welfare.
