1)         If a facility has a stairway, the stairway must have a minimum headroom of six feet, eight inches and a maximum height of 12 feet between landings.  A minimum clear width of three feet is required, except for handrails which may project three and one-half inches on each side.  A handrail is required only on one side of the stairs.  Width of treads, exclusive of nosing or projection, may not be less than nine inches.  Risers may not be more than eight inches.  Every stairway landing shall be at least as deep as the width of any stairway door which opens onto the landing.  Stairways with triangular or winding treads are permissible providing the stairways are at least three feet wide and the width of each tread is not narrower than six inches at any point. A stairway consisting of a single riser is not acceptable.  (B)


2)         For facilities licensed on or before October 1, 1987, the following exceptions to subsection (a)(1) of this Section shall apply:


A)        For all stairways, a minimum clear width of 26 inches (rather than three feet) is required.


B)        For stairways with triangular or winding treads, the stairway may be no less than 26 inches wide (rather than three feet) and the width of each tread may be narrower than six inches for up to 25 percent of the tread.

b)         Handrails at stairways shall be one and one-half inches in diameter and one and one-half inches minimum clear of the wall.


c)         Every facility shall have a ceiling height of seven feet, six inches or more, throughout all rooms occupied or used by residents.  Any projection from the ceiling shall have a clearance of at least six feet, eight inches from the floor. Ceiling heights of basements may be seven feet.


d)         Every required exit door to the outside shall be of the side hinged swinging type, and have a minimum width of 36 inches.

However, at the two required exits at the first floor there can be no step.  This is to provide accessibility for handicapped staff or visitors, if administration and public areas are located within the facility.
