The following modifications and exceptions to the limitations imposed by the Chapter are permitted under the terms and specifications herein set forth.

The height limitations of this Chapter shall not apply to church spires, belfries, cupolas, penthouses and domes not used for human occupancy; nor chimneys, ventilators, skylights, water tanks, silos, barns, bulkheads, or similar features, and necessary mechanical appurtenances usually carried above the roof level. Such features, however, shall be erected only to such height as is necessary to accomplish the purpose they are to serve. The provisions of the Chapter shall not apply to prevent the erection above the building height limit of a parapet wall or cornice for ornamental purposes to screen mechanical appurtenances. Building mounted antennas shall not exceed the height limits by more than 10 feet. Ground based antennas shall conform to the height requirements.

A single or two-family dwelling may be constructed in a district, where permitted, on any lot of nonconforming size shown on a recorded subdivision plot or any lot of official record at the time of enactment of this Chapter provided that the owner of such lot does not own any adjoining lot or adjacent land. Improvements or additions may be made without Municipal Agency approval, provided the improvement or addition does not encroach on any front, rear or side yard setback requirements and meets all other provisions of this Chapter. A building permit must be obtained.

Where the owner of a lot of substandard size owns adjacent lots or parcels of land such lots or parcels shall be considered as a single lot and the area and yard space provisions of this Chapter shall hold.
