The City of Country Club Hills operates under the Mayor/Council form of government, pursuant to Chapter 65 of the Illinois Compiled Statutes, with a City Manager established by Ordinance. Until 1993, the City was divided into four wards. The population growth recorded in the 1990 census necessitated the addition of a ward with two additional Aldermen. The City is now divided into five wards. From 1990-2013 ten alderpersons represented the five wards of the City. In 2013 a referendum passed reducing the number of alderpersons from ten to five, having one alderperson represent each ward as part of the City Council.

The Aldermen represent the policy-making branch of local government and are responsible for enacting all legislation for the health, safety and welfare of the residents of the City. In furtherance of these responsibilities, the Council meets weekly, alternating regular (voting) meetings with administrative (discussion) meetings. Aldermen serve as Chairperson on one of five committees: Finance; Law & Ordinance and Contract and Compliance; Public Works; Economic Development,Planning & Zoning ; Risk Management,Insurance and Personnel.
