Macoupin County, Illinois Roofing Permit Regulations and County Ordinances for Unincorporated Areas
Macoupin County Building & Safety Jurisdiction
Macoupin County does not maintain a centralized county-wide building and safety department that oversees all construction projects. The county operates a limited permit system, primarily focused on specific programs such as private sewage disposal, water wells, and certain new construction projects that require a septic system. There is no county-wide zoning ordinance for unincorporated areas.
Roofing Permit Requirements in Unincorporated Areas
Macoupin County does not have a general building permit requirement for roofing projects in unincorporated areas. Because the county lacks comprehensive building codes and a centralized building department, there is no county-level permit process for standard roof repairs or replacements. However, property owners should be aware of the following:
- Local Jurisdiction: If your property is located within the limits of a city or village, you must contact that specific municipality to determine their local building permit and licensing requirements, as they may have their own ordinances.
- Contractor Licensing: While the county may not issue a roofing permit, Illinois state law requires roofing contractors to hold a valid state-issued roofing license to perform roofing or waterproofing work.
- Property Improvements: Even if a permit is not required by the county, significant improvements to a property may still need to be reported to the local assessor's office for tax assessment purposes (e.g., using Form PTAX-760).

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.
