In any room in any dwelling unit there shall be provided fifty square feet of living area for each adult and twenty-five square feet of living area for each child under twelve years of age occupying such room.
(2) In calculating the floor area of attics or top half-stories, only those portions of the floor area of the room having a clear ceiling height of five feet or more shall be included.
(b) Ceiling Height. Habitable rooms in existing structures or accessory structures shall have a clear ceiling height over the minimum area required by this Code of not less than seven and one-third feet, except that in attics or top half-stories the ceiling height shall be not less than seven feet or not less than one-third of the minimum area required by this Code when used for sleeping, study or similar activity.
(c) Public Access. No habitable room, bathroom or water closet compartment in any dwelling unit shall open directly into or shall be used in conjunction with a food store, barber or beauty shop, doctor's or dentist's examination or treatment room or similar room used for public purposes.
(d) Access to Bathrooms and Water Closet Compartments. No structure or dwelling unit containing two or more sleeping rooms shall have each room arrangement such that access to a bathroom or water closet compartment intended to be used by occupants of more than one sleeping room can be obtained only by access through another sleeping room, nor shall the room arrangement be such that access to a sleeping room can be obtained only by access through another sleeping room or a bathroom or water closet compartment. Existing one-family dwellings where there are no lodgers are exempt from the requirement concerning access through a first sleeping room. (Ord. 95-1. Passed 2-20-95.)
