Cal. Corporations Code - CORP § 18330. Section 18330.
Except as otherwise provided by statute or by an unincorporated association’s governing principles, the following rules govern a member vote conducted pursuant to this chapter:
(a)
A vote may be conducted either at a member meeting at which a quorum is present or by a written ballot in which the number of votes cast equals or exceeds the number required for a quorum. Approval of a matter voted on requires an affirmative majority of the votes cast.
(b)
Written notice of the vote shall be delivered to all members entitled to vote on the date of delivery. The notice shall be delivered or mailed or sent electronically to the member addresses shown in the association’s records a reasonable time before the vote is to be conducted. The notice shall not be delivered electronically, unless the recipient has consented to electronic delivery of the notice. The notice shall state the matter to be decided and describe how and when the vote is to be conducted.
(c)
If the vote is to be conducted by written ballot, the notice of the vote shall serve as the ballot. It shall set forth the proposed action, provide an opportunity to specify approval or disapproval of any proposal, and provide a reasonable time within which to return the ballot to the unincorporated association.
(d)
One-third the voting power of the association constitutes a quorum.
(e)
The voting power of the association is the total number of votes that can be cast by members on a particular issue at the time the member vote is held.
