§ 151.19 SPACE, USE, AND LOCATION.
   (A)   Room sizes.
      (1)   Every dwelling unit shall contain at least the minimum room size in each habitable room as required by the State Residential Building Code.
      (2)   Every dwelling unit shall contain at least 150 square feet of habitable floor area for the first occupant, at least 100 square feet of additional habitable area for each of the next three occupants and at least 75 square feet of additional habitable floor area for each additional occupant.
      (3)   In every dwelling unit and in every rooming unit, every room occupied for sleeping purposes by one occupant shall contain at least 70 square feet of floor area, and every room occupied for sleeping purposes by more than one occupant shall contain at least 50 square feet of floor area for each occupant 12 years of age and over and at least 35 square feet of floor area for each occupant under 12 years of age.
   (B)   Ceiling height. All full stories must have all ceiling heights a minimum of seven feet, six inches in all habitable rooms. All attic areas for habitable use must have a ceiling height of at least seven feet, six inches over one-third of each room.
   (C)   Floor area calculation. Floor area shall be calculated on the basis of habitable room area. The floor area of any space where the ceiling height is less than four and one-half feet shall not be considered habitable room area and, therefore, not considered as part of the floor area for the purpose of determining maximum permissible occupancy.
   (D)   Cellar. No cellar shall be used for living purposes.
   (E)   Basements. No basement shall be used for living purposes unless: the floor and walls are substantially watertight; the total window area, total openable window areas, and ceiling height are equal to those required for habitable rooms; and the required minimum window area of every habitable room is entirely above the grade adjoining such window area, except where the window or windows face a stairwell, window well, or accessway.
