The governing body of any county, city, or township may permit the use of or may lease any public building or any part of a public building under its charge for any legal purpose, giving equal opportunity to all persons, and without religious or political distinctions, and may make such reasonable rules and restrictions on the use of such building as may seem necessary, and shall fix proper rentals and fees for such use. Such governing body, in its discretion, may require a bond from the lessee or user of such building, conditioned upon the payment of charges made for such lease or use and indemnifying the county, city, or township against damage or destruction of or to such building or any part thereof.
