27A V.S.A. § 3-121

(a) An association shall deliver any notice required to be given by the association under this title to any mailing or electronic mail address a unit owner designates. Otherwise, the association may deliver notices by: (1) hand delivery to each unit owner; (2) hand delivery, U.S. mail postage paid, or commercially reasonable delivery service to the mailing address of each unit; (3) electronic means, if the unit owner has given the association an electronic address; or (4) any other method reasonably calculated to provide notice to the unit owner. (b) The ineffectiveness of a good faith effort to deliver notice by an authorized means does not invalidate action taken at or without a meeting. (Added 2009, No. 155 (Adj. Sess.), § 39, eff. Jan. 1, 2012.)
