An authority will generally meet each month, but the frequency of such meetings will be as required by the amount or nature of the business to be transacted. Whenever necessary, an authority shall meet to select a chairman and vice-chairman as provided in section 32 of the Public Housing Law, as well as such other officers as it deems necessary. Proper notice should be forwarded sufficiently in advance so as to be received by each member at least two days prior to the date of a meeting. A majority of the members of an authority shall constitute a quorum.
