Unless the condominium instrument expressly provides for a greater percentage or different procedures a two-thirds majority of the unit owners at a meeting of unit owners duly called for such purpose may elect to dedicate a portion of the common elements to a public body for use as, or in connection with, a street or utility. Where such a dedication is made, nothing in this Act or any other law shall be construed to require that the real property taxes of every unit of the condominium must be paid prior to recordation of the dedication.
