Floor area shall be calculated on the basis of habitable room area.  However, closet area and hall area within the dwelling unit, where provided, may count for not more than five percent (5%) of the required habitable floor area.
   At least one-half of the floor area of every habitable room shall have a ceiling height of at least seven feet, and the floor area of any part of any room where the ceiling height is less than five feet shall not be considered as part of the floor area in computing the total floor area of the room to determine maximum permissible occupancy.
