Saline County, Illinois Roofing Permit Regulations and County Ordinances for Unincorporated Areas
Roofing Permit Requirements in Saline County, Illinois
In Illinois, building permit requirements are highly localized, as there is no single statewide building code that mandates uniform permitting for all residential roofing projects. Consequently, regulations vary significantly depending on the specific jurisdiction where the property is located.
For properties located in the unincorporated areas of Saline County, there is no centralized county-wide building department that enforces a universal residential roofing permit requirement. However, property owners should be aware of the following:
- Local Jurisdiction: While the county may have authority over specific land-use or specialized ordinances (such as those regulating commercial solar farms), it does not necessarily maintain a general building permit system for standard residential roof repairs or replacements in unincorporated areas.
- State Licensing Requirements: Regardless of whether a local permit is required, Illinois law mandates that all roofing contractors must hold a valid Limited or Unlimited Roofing License issued by the Illinois Department of Financial and Professional Regulation (IDFPR). You should always verify that your contractor is properly licensed before beginning any work.
- Verification: Because regulations can change or be subject to specific zoning overlays, it is strongly recommended that you contact the Saline County Clerk's office or the relevant county administrative office to confirm if any specific local ordinances apply to your property before starting a roofing project.

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.
