Illinois, Henry County Roofing Permit Regulations and County Ordinances for Unincorporated Areas
Henry County Building & Safety Jurisdiction
In Henry County, Illinois, building and safety regulations are managed by the Zoning and Building Department. The county has adopted the International Building Code (IBC) to establish minimum standards for construction, alteration, repair, and other building-related activities. Any owner or authorized contractor intending to perform such work must obtain a building permit before starting. Failure to secure a permit prior to beginning work is considered an ordinance violation and may result in stop-work orders, fines, and penalties.
Roofing Permit Requirements in Unincorporated Areas
Properties located in the unincorporated areas of Henry County are subject to the county's building code and zoning ordinances. When applying for a building permit, applicants must provide specific information, including the name, address, and telephone number of the roofing contractor. Crucially, Illinois law requires that roofing contractors be licensed; this license number must be included on the permit application. If a property owner intends to perform the work themselves, they must indicate this on the application. It is recommended to contact the Henry County Zoning and Building Department directly to confirm if your specific roofing project requires a permit, as requirements can depend on the scope of the 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.
