     § 4210.  Alterations of units.        Subject to the provisions of the declaration, section 4321(c)     (relating to limited equity cooperatives) and other provisions     of law, a proprietary lessee:            (1)  May make any improvements or alterations to his unit        that do not impair the structural integrity or mechanical        systems or lessen support of any portion of the cooperative.            (2)  May not change the common elements or the exterior        appearance of a unit without permission of the association.            (3)  After acquiring a cooperative interest of which an        adjoining unit or an adjoining part of an adjoining unit is a        part, may remove or alter any intervening partition or create        apertures therein, even if the partition in whole or in part        is a common element, if those acts do not impair the        structural integrity or mechanical systems or lessen the        support of any portion of the cooperative. Removal of        partitions or creation of apertures under this paragraph is        not an alteration of boundaries.        Cross References.
