Except as specifically stated in other parts of this Ordinance, no building shall be erected, converted, enlarged, reconstructed or structurally altered to exceed the height limit hereinafter established for the district in which the building is located, except that penthouse or roof structures for the housing of elevators, stairways, tanks, ventilating fans or similar equipment required to operate and maintain the building, and fire or parapet walls, skylights, towers, steeples, stage lofts and screens, flag poles, chimneys, smokestacks, radio and television aerials, wireless masts, water tanks or similar structures may be erected above the height limits herein. No such structure may, however, be erected to exceed by more than fifteen feet (15') the height limits of the district in which it is located; nor shall such structure have a total area greater than twenty-five percent (25%) of the roof area of the building; nor shall such structure be used for any residential purpose other than a use incidental to the main use of the building. Radio, television and wireless aerials or masts shall be limited to a height of 35 feet above ground level in any residential district, but may be erected to any height in a nonresidential district, providing they conform to Federal Aviation Administration and Federal Communication Commission regulations and said height is approved by the Planning Commission.
However, public and semipublic or public service buildings, when permitted in a district, may be erected to a height not to exceed sixty feet (60'), and churches and temples may be erected to a height not to exceed seventy-five feet (75') if the building is set back from each lot line at least one foot (1') for each foot of additional building height above the height limit otherwise provided in the district in which the building is built.
