A declaration may not specify a smaller number unless all of the units are restricted exclusively to nonresidential use.

(b) An action to challenge the validity of an amendment adopted by the association under this section may not be brought more than one year after the amendment is recorded.

(c) Each amendment to the declaration must be recorded, and a plat or plan that accompanies the amendment filed and recorded, in each recording district in which a portion of the common interest community is located and the amendment is effective only upon recording. An amendment, except an amendment under AS 34.08.200(a), must be indexed in the name of the common interest community and the association and in the name of the parties executing the amendment.

(d) Except to the extent expressly permitted or required in this chapter, an amendment may not create or increase special declarant rights, increase the number of units, or change the boundaries of a unit, the allocated interests of a unit, or the uses to which a unit is restricted, in the absence of unanimous consent of the unit owners.

The agreement is effective 30 days after an amendment to the declaration reflecting the terms of the agreement is recorded unless all persons holding special declarant rights affected by the amendment or security interests in those rights

(1) record a written objection within the 30-day period, in which case, the amendment is void; or

(2) consent in writing when the amendment is recorded, in which case, the amendment is effective when recorded.
