27A V.S.A. § 3-109

(a) Unless the bylaws provide otherwise, a quorum is present throughout any meeting of the unit owners if persons entitled to cast 20 percent of the votes in the association: (1) are present in person or by proxy at the beginning of the meeting; (2) have cast absentee ballots solicited in accordance with subdivision 3-110(c)(4) of this title that have been delivered to the secretary in a timely manner; or (3) are present by any combination of subdivisions (1) and (2) of this subsection. (b) Unless the bylaws specify a larger number, a quorum of the executive board is present for purposes of determining the validity of any action taken at a meeting of the executive board only if individuals entitled to cast 50 percent of the votes on that board are present at the time a vote regarding that action is taken. If a quorum is present when a vote is taken, the affirmative vote of a majority of the board members present is the act of the executive board unless a greater vote is required by the declaration or bylaws. (c) Except as otherwise provided in the bylaws, meetings of the association shall be conducted in accordance with the most recent edition of Roberts’ Rules of Order Newly Revised.
