Exceptions to height limits. Structures on the roof of a building, such as water tanks, ventilating fans, air-conditioning equipment, towers, steeples, flagpoles, chimneys, wireless masts or other similar structures, may exceed the height limits prescribed in this chapter by six feet; provided, however, that antennas may exceed the height limitation prescribed in this chapter by 20 feet.

Exceptions to area requirements. A single-family dwelling may be constructed in a district where permitted on any lot shown on a recorded subdivision plat or any lot of official record on the effective date of this chapter, the owner of which does not own any adjoining lot or adjacent land, provided that, in the opinion of the Board of Adjustment, the lot area and proposed yard requirements of this chapter for the district in which such lot is located are met. If the owner of a lot of substandard size owns adjacent lots or parcels it shall be considered as a single lot area, and yard space provisions of this chapter shall apply.

Exceptions to setback requirements. Setbacks on lots fronting on culs-de-sac shall be computed by measuring back on each side line the required distance and then striking a line between the two points, provided that in no event shall any building be erected less than 15 feet from the street line.[1]
