    Sec. 4.1. Construction, interpretation, and validity of Condominium Instruments.
    (a) Except to the extent otherwise provided by the declaration or other condominium instruments:
        (1) The terms defined in Section 2 of this Act shall
be deemed to have the meaning specified therein unless the context otherwise requires.
        (2) To the extent that perimeter and partition walls,
floors or ceilings are designated as the boundaries of the units or of any specified units, all decorating, wall and floor coverings, paneling, molding, tiles, wallpaper, paint, finished flooring and any other materials constituting any part of the finished surfaces thereof, shall be deemed a part of such units, while all other portions of such walls, floors or ceilings and all portions of perimeter doors and all portions of windows in perimeter walls shall be deemed part of the common elements.
        (3) If any chutes, flues, ducts, conduits, wires,
bearing walls, bearing columns, or any other apparatus lies partially within and partially outside of the designated boundaries of a unit, any portions thereof serving only that unit shall be deemed a part of that unit, while any portions thereof serving more than one unit or any portion of the common elements shall be deemed a part of the common elements.
        (4) Subject to the provisions of paragraph (3) of
subsection (a), all space and other fixtures and improvements within the boundaries of a unit shall be deemed a part of that unit.
        (5) Any shutters, awnings, window boxes, doorsteps,
porches, balconies, patios, perimeter doors, windows in perimeter walls, and any other apparatus designed to serve a single unit shall be deemed a limited common element appertaining to that unit exclusively.
        (6) All provisions of the declaration, bylaws and
other condominium instruments are severable.
    (b) Except to the extent otherwise provided by the declaration or by other condominium instruments recorded prior to the effective date of this amendatory Act of 1984, in the event of a conflict between the provisions of the declaration and the bylaws or other condominium instruments, the declaration prevails except to the extent the declaration is inconsistent with this Act.
    (c) A provision in the initial declaration limiting ownership, rental or occupancy of a condominium unit to a person 55 years of age or older shall be valid and deemed not to be in violation of Article 3 of the Illinois Human Rights Act provided that the person or the immediate family of a person owning, renting or lawfully occupying such unit prior to the recording of the initial declaration shall not be deemed to be in violation of such age restriction so long as they continue to own or reside in such unit.
