That whenever the legislative body of any county or township within the state of Michigan and the legislative body of any village or city situated in such county or township shall deem it expedient and for the public convenience and welfare that the offices of the city or village and county or township can be best maintained in the same building and when such legislative bodies shall have so declared by resolution, appearing upon the minutes of said bodies, it shall be lawful for such city or village and county or township and they are hereby authorized and empowered to contract to and with each other, through their proper representatives, for the joint acquiring and maintaining of a building or the acquiring of a site or sites and the erection, construction and maintenance of a building erected for and dedicated to public uses.

     The cities, villages, townships and counties aforesaid, acting under the provisions of this act, shall have power and are hereby authorized, through their proper agents, servants and employes to enter into the necessary contracts with each other and with other persons for the acquiring and maintaining of a building or the acquiring of a site or sites and the erection, construction and maintenance, either jointly or severally, in any manner which may be necessary and which they shall deem expedient for the purpose of establishing and maintaining joint ownership, operation and maintenance of a building or buildings to be used for public purposes to the extent and in the manner now provided by law.

     The cities, villages, townships and counties aforesaid, acting under the provisions of this act, shall have power and they are hereby authorized to raise by taxation or loan in sum or sums necessary for the payment of obligations entered into under the provisions of this act in the manner and to the extent provided by law for the acquiring and maintenance of public buildings by such municipalities, it being the intent and purpose of this act that counties and cities may enter into joint adventures in the erection of buildings for public purposes to the same extent and with the same authority and power that is granted to counties and cities for the purpose of maintaining separate public buildings.

     Whenever a village or city or cities and a county or township shall desire to act under the provisions of this law, the relationship established between such municipalities and governmental agencies shall be fixed by contract and such contracts may be made by cities and counties under the provisions of this act in the manner and to the extent that natural persons might make contracts for like purposes. Such contracts before becoming operative shall be approved by a vote of a majority of all the members-elect of the legislative bodies of the counties and cities operating under the provisions of this act.

    (1) A county, city, village, or township for itself and any other of the units of government may acquire, construct, lease, or maintain a building or buildings to house any of their offices, or facilities for any other public use and purpose of the units of government, which building may be or include a memorial hall for war veterans of the United States of America and for public assemblage and to acquire a site or sites for those purposes. However, no county, city, village, or township shall for joint purposes and uses acquire a site or sites or erect any building or buildings unless the unit of government has entered into a contract or contracts for the rental of a portion of the site or sites and quarters or space with each of the other participating units of government in the amount or amounts and for the period or periods of time and in the form as will provide revenues from payments to it of a reasonably proportionate or equitable share of the total cost in relation to the portion, space, use, and public benefits provided in the contract or contracts for the lessee or lessees. The contract or contracts shall be executed following approval by a majority vote of the members elected to and serving in the legislative body of each unit of government participating in and a party to the contract. The contract is not subject to the revised municipal finance act, 2001 PA 34, MCL 141.2101 to 141.2821.

    (2) The county, city, village, or township that singly acquires a site or sites or acquires, constructs, or leases a building or buildings for the purposes authorized in this section may obtain funds for those purposes by gift or by means of general obligation bonds or by the issuance of self-liquidating revenue bonds to be paid from the revenues derived in pursuance of a contract or contracts as provided in subsection (1) and under the provisions of the revenue bond act of 1933, 1933 PA 94, MCL 141.101 to 141.140. In the event that the revenues to be derived under the contract or contracts shall be only sufficient to permit the issuance of revenue bonds for a portion of the cost of the site or sites or building or buildings, authority is hereby granted to issue revenue bonds to the extent to which the revenue shall permit. However, the entire improvement or improvements on which revenue bonds are issued shall be subject to the provisions of the revenue bond act of 1933, 1933 PA 94, MCL 141.101 to 141.140. However, as a prerequisite to the lease or purchase of any property, the lease, purchase, or construction of any building or buildings or the issuance of any revenue or general obligation bonds under the provision of this section, the board of commissioners of the county involved shall submit the question to the qualified electors of the county at the next general election or at a special election to be called by the board of commissioners of the county. However, if the majority vote of the qualified electors in the largest city of the county and a majority vote of the qualified electors in all the rest of the county shall vote in favor of the question, the provisions of this section shall then become operative. However, no self-liquidating revenue bonds shall be sold unless prior to the sale an advertisement is made of the date of the sale, the number and amount of bonds, and other matters covering the revenue bonds. However, sealed bids shall be taken on the day of the sale of the bonds from any and all persons who may bid, and the bonds shall be sold to the highest bidder at the sale. The proceeds derived from the sale of any and all the bonds shall be used only for the purpose of acquiring a site or constructing building or buildings, as authorized in this act, and shall be used for no other purpose.

    (3) The provisions of this section shall apply only to counties having a population of 300,000 or over according to the latest federal census. However, the provisions of this section shall not apply in a county unless and until the board of supervisors of the county shall adopt a resolution approved by a 2/3 vote of the members elected to and serving on the board.

    (4) General obligation bonds issued under this act are subject to the revised municipal finance act, 2001 PA 34, MCL 141.2101 to 141.2821.
