“Height of building” means the vertical distance measured from the finished grade to the highest point of the roof for flat roofs, to the deck line of mansard roofs, and to the mean height between eaves and ridge for gable, hip and gambrel roofs. If a structure has none of the above features then the height shall be measured from the finished grade to the highest portion of the structure. See Figure 18.04.200. (Ord. 6245 § 3, 2009; Ord. 4229 § 2, 1987.)
