(A) Building Height
Building height is the vertical distance measured from the average elevation of the proposed finished grade at the front of the building to the highest point of the roof deck of a flat roof, to the highest point of a mansard roof, or to the mean height level between the eaves and ridge of a gable, hip, or gambrel roof.
(B) Exceptions
Parapets, spires, cupolas, antennae attached to a building, projections from buildings, mechanical equipment, and accessory structures associated with an activated roof deck, are not to be included in the calculation of building height.
