(d) Except to the extent expressly permitted or required by other provisions of this chapter, no amendment may create or increase special declarant rights, increase the number of units, change the boundaries of any unit, the allocated interests of a unit, or the uses to which any unit is restricted, in the absence of unanimous consent of the unit owners.
