Cook County Building & Safety Jurisdiction
The Cook County Department of Building and Zoning is the authority responsible for issuing building permits for properties located within unincorporated Cook County.

Property owners should verify their jurisdiction using the county's interactive mapping tool, CookViewer, before beginning any project.

- Information regarding any associated work, such as flashing, gutters, downspouts, soffit, or fascia.
- If structural work (such as rafter replacement or chimney reconstruction) or the installation of power vents/attic fans is involved, additional documentation or letters of intent from licensed contractors may be required.

State-Level Building Codes and Legislation for Roofing in Illinois
As of January 1, 2025, Illinois has implemented a statewide baseline building code requirement pursuant to Public Act 103-0510, which amended the Capital Development Board Act. This legislation mandates that all municipalities and counties in Illinois must adopt and enforce building codes that meet or exceed the minimum structural requirements of the International Code Council (ICC) standards, specifically the International Building Code (IBC) and the International Residential Code (IRC). Prior to this, Illinois did not have a unified statewide building code, and regulations were determined entirely at the local municipal or county level.
While the state now requires a baseline, local jurisdictions retain the authority to adopt their own specific editions (such as the 2018, 2021, or 2024 editions) and implement local amendments, provided those amendments do not reduce the structural requirements below the state-mandated baseline. Consequently, specific roofing requirements—such as those for ice and water shields, ventilation, and shingle layering—can still vary significantly between different cities, villages, and counties. Property owners and contractors must consult their local Authority Having Jurisdiction (AHJ) to confirm the specific code edition and local amendments applicable to their project.
Primary State Agency
The Illinois Capital Development Board (CDB) is the primary state agency responsible for the administration of the state's building code framework. Under the Capital Development Board Act (20 ILCS 3105), the CDB is tasked with identifying and publishing local building codes and ensuring that municipalities and counties comply with the requirement to report their adopted codes and amendments to the state.
