(1) Notice to the association, board, or any owner or occupant of a unit under this chapter must be provided in the form of a record.

(2) Notice provided in a tangible medium may be transmitted by mail, private carrier, or personal delivery; telegraph or teletype; or telephone, wire, or wireless equipment that transmits a facsimile of the notice.

(a) Notice in a tangible medium to an association may be addressed to the association's registered agent at its registered office, to the association at its principal office shown in its most recent annual report or provided by notice to the unit owners, or to the president or secretary of the association at the address shown in the association's most recent annual report or provided by notice to the unit owners.

(b) Notice in a tangible medium to a unit owner or occupant must be addressed to the unit address unless the unit owner or occupant has requested, in a record delivered to the association, that notices be sent to an alternate address or by other method allowed by this section and the governing documents.

(3) Notice may be provided in an electronic transmission as follows:

(a) Notice to unit owners or board members by electronic transmission is effective only upon unit owners and board members who have consented, in the form of a record, to receive electronically transmitted notices under this chapter and have designated in the consent the address, location, or system to which such notices may be electronically transmitted, provided that such notice otherwise complies with any other requirements of this chapter and applicable law. An owner's consent under this subsection (3)(a), and any other notice in the form of a record delivered to the association from time to time, may indicate whether the owner elects to keep the owner's electronic address confidential and exempt from disclosure by the association pursuant to RCW 64.90.495(2). Failure to deliver such notice permits disclosure by the association.

(b) Notice to unit owners or board members under this subsection includes material that this chapter or the governing documents requires or permits to accompany the notice.

(c) A unit owner or board member who has consented to receipt of electronically transmitted notices may revoke this consent by delivering a revocation to the association in the form of a record.

(d) The consent of any unit owner or board member is revoked if: The association is unable to electronically transmit two consecutive notices given by the association in accordance with the consent, and this inability becomes known to the secretary of the association or any other person responsible for giving the notice. The inadvertent failure by the association to treat this inability as a revocation does not invalidate any meeting or other action.

(e) Notice to unit owners or board members who have consented to receipt of electronically transmitted notices may be provided by posting the notice on an electronic network and delivering to the unit owner or board member a separate record of the posting, together with comprehensible instructions regarding how to obtain access to the posting on the electronic network.

(f) Notice to an association in an electronic transmission is effective only with respect to an association that has designated in a record an address, location, or system to which the notices may be electronically transmitted.

(4) Notice may be given by any other method reasonably calculated to provide notice to the recipient.

(5) Notice is effective as follows:

(a) Notice provided in a tangible medium is effective as of the date of hand delivery, deposit with the carrier, or when sent by fax.

(b) Notice provided in an electronic transmission is effective as of the date it:

(i) Is electronically transmitted to an address, location, or system designated by the recipient for that purpose; or

(ii) Has been posted on an electronic network and a separate record of the posting has been sent to the recipient containing instructions regarding how to obtain access to the posting on the electronic network.

(6) The ineffectiveness of a good faith effort to deliver notice by an authorized means does not invalidate action taken at or without a meeting.

(7) If this chapter prescribes different or additional notice requirements for particular circumstances, those requirements govern.
