Before preparing your meeting notice, review the bylaws to determine the terms of the positions up for election. The Illinois Condominium Act requires that notice of meetings be delivered and posted at least 48 hours prior to the meeting.This guide provides summaries of key laws and regulations that govern Chicago's boards and commissions. The notice must state the place, date, hour, means of remote communication and, in the case of a special meeting, the purpose of the meeting. Generally, the date of the annual meeting is contained in the bylaws of the corporation. The typical window for submitting proposals pursuant to an advance notice bylaw is about three months before the annual meeting. The annual meeting must be held once per year.
