Subject to the provisions of the declaration and other provisions of law, all of the following apply:
(1) A unit owner may make any improvements or alterations to the unit that do not impair the structural integrity or mechanical systems or lessen the support of any portion of the planned community.
(2) A unit owner may not change the appearance of the common elements or any other portion of the planned community other than portions of units that are not controlled facilities without the permission of the association. However, a unit owner may change the exterior appearance of a unit except any portion of a unit which is a controlled facility without the permission of the association.
(3) After acquiring an adjoining unit or an adjoining part of an adjoining unit, a unit owner 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 planned community. Removal of partitions or creation of apertures under this paragraph is not an alteration of boundaries.
