Illinois, Coles County Roofing Permit Regulations and County Ordinances for Unincorporated Areas
Coles County Building and Safety Jurisdiction
Coles County, Illinois, does not maintain a centralized county-level building and safety division that requires building permits for general residential or commercial construction projects. The county generally does not require building permits, engineering reports, or property specifications for most developments. However, specific ordinances do exist to regulate the location, siting, and operations of certain developments, such as subdivisions, regional pollution control facilities, and commercial solar or wind energy projects.
Rules for Properties in Unincorporated Areas
For properties located in unincorporated areas of Coles County—those outside the zoning jurisdictions of municipalities like Mattoon, Charleston, Oakland, Lerna, Humboldt, and Ashmore—there is no county-level zoning or building permit requirement for standard roofing work. While the county does not mandate permits, all development must still conform to applicable state and federal laws. Property owners should be aware that while a county permit may not be required, state law requires that roofing contractors hold a valid license issued by the Illinois Department of Financial and Professional Regulation to perform roofing work.

Illinois Roofing Legislation, Codes, and Guidelines
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.
