Clinton County Building & Safety Jurisdiction
In Clinton County, Illinois, the primary office responsible for land use, zoning, and building-related inquiries is the Clinton County Zoning Office. This office is located in the lower level of the courthouse (Room 124) at 850 Fairfax Street, Carlyle, IL 62231. The Zoning Office administers the Clinton County Zoning Ordinance, which governs development in the unincorporated areas of the county and in municipalities that have not adopted their own zoning ordinances.
Roofing Permit Requirements for Unincorporated Areas
For properties located in the unincorporated areas of Clinton County, a building permit is generally not required for re-roofing, window replacement, or similar maintenance projects. While the county regulates various types of construction through zoning certificates—such as new homes, decks, sheds, and garages—routine roofing maintenance is typically exempt from the permit process. However, it is always recommended to contact the Clinton County Zoning Office directly to confirm the status of your specific project, as regulations can be subject to change and specific circumstances may vary.

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.
