(1)(a) If the declaration provides that any of the powers described in RCW 64.90.405 are to be exercised by or may be delegated to a for-profit corporation or limited liability company that exercises those or other powers on behalf of unit owners owning less than all of the units in a common interest community, and if those unit owners share the exclusive use of one or more limited common elements within the common interest community or share some property or other interest in the common interest community in common that is not shared by the remainder of the unit owners in the common interest community, all provisions of this chapter applicable to unit owners associations apply to any such corporation or limited liability company, except as modified under this section.

(b) The delegation of powers to a subassociation must not be used to discriminate in favor of units owned by the declarant or an affiliate of the declarant.

(2) A subassociation may exercise the powers set forth in RCW 64.90.405 only to the extent expressly permitted by the declaration of the common interest community of which the units in the subassociation are a part of or expressly described in the delegations of power from that common interest community to the subassociation.

(3) If the declaration of any common interest community contains a delegation of certain powers to a subassociation, or provides that the board of the common interest community may make such a delegation, the board members are not liable for the acts or omissions of the subassociation with respect to those powers so exercised by the subassociation following delegation.

(4) The rights and responsibilities of unit owners with respect to the unit owners association set forth in RCW 64.90.400 through 64.90.500 apply to the conduct of the affairs of a subassociation.

(5) Notwithstanding RCW 64.90.415(4), the board of the subassociation must be elected after any period of declarant control by the unit owners of all of the units in the common interest community subject to the subassociation.

(6) The declaration of the common interest community creating the subassociation may provide that the authority of the board of the subassociation is exclusive with regard to the powers and responsibilities delegated to it. In the alternative, the declaration may provide as to some or all such powers that the authority of the board of a subassociation is concurrent with and subject to the authority of the board of the unit owners association, in which case the declaration must also contain standards and procedures for the review of the decisions of the board of the subassociation and procedures for resolving any dispute between the board of the unit owners association and the board of the subassociation.
