C. SUPPLEMENTARY HEIGHT REGULATIONS

1. Height exceptions.

The height limits for the various districts shall not apply to church spires, belfries, cupolas, penthouses, or domes not used for human habitation, nor to chimneys, ventilators, skylights, water tanks, parapet walls, cornices, or necessary mechanical appurtenances usually carried above the roof level and noncommercial radio and television tower, provided that such features are limited to that height necessary for their proper functioning.

2. Excess height.

In any district any main structure may be erected or altered to a height in excess of that specified for the district in which the structure is located provided that each required front, side, and rear yard is increased one (1) foot for each foot of such excess

height; provided, further, that where no front yard is required the part of the structure exceeding the height specified for the district shall be set back from the vertical planes of all street lines one (1) foot for each two (2) feet of such excess height.

a. Compensating bulk and open space. To permit variety in the shape and bulk of structures, in any district part of a main structure may be erected or altered to a height in excess of that specified for the district in which the structure is located without increasing the yards or creating the setback as required above provided a volume of space occupied by the part of the structure exceeding the height limit is provided and kept open below the height limit; it is intended that such open space below the height limit shall compensate for the excessive bulk above the height limit, and to this and both the excess bulk and the compensating open space shall be provided on the same building site.

3. Accessory structures.

No accessory structure shall exceed the height of the main structure.
