Sec. 5.

(1) A meeting of a public body shall not be held unless public notice is given as provided in this section by a person designated by the public body.

(2) For regular meetings of a public body, there shall be posted within 10 days after the first meeting of the public body in each calendar or fiscal year a public notice stating the dates, times, and places of its regular meetings.

(3) If there is a change in the schedule of regular meetings of a public body, there shall be posted within 3 days after the meeting at which the change is made, a public notice stating the new dates, times, and places of its regular meetings.

(4) Except as provided in this subsection or in subsection (6), for a rescheduled regular or a special meeting of a public body, a public notice stating the date, time, and place of the meeting shall be posted at least 18 hours before the meeting. The requirement of 18-hour notice shall not apply to special meetings of subcommittees of a public body or conference committees of the state legislature. A conference committee shall give a 6-hour notice. A second conference committee shall give a 1-hour notice. Notice of a conference committee meeting shall include written notice to each member of the conference committee and the majority and minority leader of each house indicating time and place of the meeting. This subsection does not apply to a public meeting held pursuant to section 4(2) to (5) of Act No. 239 of the Public Acts of 1955, as amended, being section 200.304 of the Michigan Compiled Laws.

(5) A meeting of a public body which is recessed for more than 36 hours shall be reconvened only after public notice, which is equivalent to that required under subsection (4), has been posted. If either house of the state legislature is adjourned or recessed for less than 18 hours, the notice provisions of subsection (4) are not applicable. Nothing in this section shall bar a public body from meeting in emergency session in the event of a severe and imminent threat to the health, safety, or welfare of the public when 2/3 of the members serving on the body decide that delay would be detrimental to efforts to lessen or respond to the threat.

(6) A meeting of a public body may only take place in a residential dwelling if a nonresidential building within the boundary of the local governmental unit or school system is not available without cost to the public body. For a meeting of a public body which is held in a residential dwelling, notice of the meeting shall be published as a display advertisement in a newspaper of general circulation in the city or township in which the meeting is to be held. The notice shall be published not less than 2 days before the day on which the meeting is held, and shall state the date, time, and place of the meeting. The notice, which shall be at the bottom of the display advertisement and which shall be set off in a conspicuous manner, shall include the following language: “This meeting is open to all members of the public under Michigan's open meetings act”.
