50 ILCS 30/6.4

Each Council has the power to acquire lands by lease, gift, purchase, condemnation or otherwise, and to construct, reconstruct or acquire by gift, grant, purchase, condemnation, lease or otherwise buildings and other structures and personal property for any purpose within the powers of such Council and to sell, transfer or convey its property, or any part thereof, except that acquired by lease, when no longer necessary or useful for its purposes or to exchange any such property for other property which it may use for any purpose within the powers of such Council.

Before a Council exercises its power to acquire land by condemnation, such condemnation must be approved by a majority of the members of the county board or corporate authorities that formed the Council.
