For the purpose of determining the ratio of the floor area of a building to the area of the lot, the “gross floor area” means the sum of the gross horizontal areas of the several floors of the building excluding areas used for accessory garage purposes and such basement and cellar areas as are devoted exclusively to uses accessory to the operation of the building. All horizontal dimensions shall be taken from the exterior faces of walls, including walls or other enclosures of enclosed porches. In computing the gross floor areas of buildings in residence districts, areas of floors with story heights greater than ten (10) feet shall be considered as H/10 times the gross area of the floor, where “H” is the height of the story in feet measured from the floor level to one (1) foot above the ceiling level for top stories, and from floor level to floor level for other stories.
