(a) Floor area, dwelling unit. Every dwelling unit must contain at least 150 square feet of floor area for the first occupant and at least 100 additional square feet of floor area for every additional occupant. The floor area of that part of any room where the ceiling height is less than 5 feet or where the room width is less than 7 feet must not be considered in computing the habitable space of the room to decide its maximum permissible occupancy.

In every dwelling unit of 2 or more rooms, every room occupied for sleeping purposes by one occupant must contain at least 70 square feet of habitable space, and every room occupied for sleeping purposes by more than one occupant must contain at least 50 square feet of habitable space for each occupant. However, in a mobile home every room occupied for sleeping purposes by one occupant must contain at least 50 square feet of habitable space; by 2 occupants, at least 70 square feet of habitable space; and by more than 2 occupants, at least an additional 50 square feet of habitable space for each additional occupant.

The floor area of that part of any room where the ceiling height is less than 5 feet or where the room width is less than 7 feet must not be considered in computing the habitable space of the room to decide its maximum permissible occupancy.
(d) Ceiling height. At least one-half of the floor area of every habitable room must have a ceiling height of at least 6 feet 8 inches, except that a beam, girder, duct or other obstruction may project to within 6 feet 4 inches of the finished floor.
