Moultrie County, Illinois Roofing Permit Regulations and County Ordinances for Unincorporated Areas
Moultrie County Building & Safety Jurisdiction
In Moultrie County, the Department of Planning and Zoning is responsible for regulating construction activities. This department oversees zoning, flood hazard regulations, and subdivision regulations. While the county has adopted the 2018 International Residential Code (IRC) and the 2024 International Building Code (IBC), the county's building inspector primarily conducts permit-based inspections for projects that require a building permit.
Roofing Permit Requirements for Unincorporated Areas
If your property is located in an unincorporated area of Moultrie County, you generally do not need a building permit for roof replacements. The county explicitly states that permits are not required for roof replacements, siding, windows, or internal remodels that do not involve major structural changes. However, if you are unsure about your specific project or property location, it is recommended to contact the Planning and Zoning Office directly to confirm requirements before beginning any 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.
