Mission

Our mission is to  promote the health, safety and welfare of residents in unincorporated Cook County.  In order to perform our mission, we conduct responsible and timely inspections of buildings and properties, as well as enforce all applicable building codes and zoning ordinances.

Our work involves issuing permits for new structures and renovations to existing ones, inspecting properties to ensure code compliance, issuing certificates of occupancy, and certifying the zoning requirements for properties in our jurisdiction, among other tasks.

Our department oversees building and zoning matters only in the unincorporated areas of Cook County. Inquiries regarding permits, zoning certificates, and other matters for properties located in incorporated jurisdictions (municipalities), should contact the applicable local building and zoning authority.
