Richland County, Illinois Roofing Permit Regulations and County Ordinances for Unincorporated Areas

Building and Safety Oversight in Richland County, Illinois

Richland County, Illinois, does not maintain a centralized county-wide building department that oversees residential roofing permits for all areas. In Illinois, building codes and permitting requirements are typically managed at the local municipal level (cities, villages, or towns). For properties located in unincorporated areas of the county, there is often no county-level building permit requirement for standard residential roofing projects, though property owners should always verify this with the county clerk or relevant county officials to ensure no specific local ordinances or floodplain regulations apply.

Permit Requirements for Unincorporated Areas

In many unincorporated areas of Illinois counties without a dedicated building department, formal building permits for residential roof repairs or replacements may not be required. However, this does not exempt property owners from other critical requirements:

State Licensing: Regardless of whether a local permit is required, Illinois law mandates that any contractor performing roofing or waterproofing work must hold a valid Limited or Unlimited Roofing License issued by the Illinois Department of Financial and Professional Regulation.
Floodplain Regulations: If your property is located within a designated floodplain, you must consult with the Richland County Engineer, who serves as the County Floodplain Administrator, to determine if your project requires a floodplain development permit.
Local Ordinances: Always contact the Richland County Clerk’s office or the county board to confirm if any specific zoning or building ordinances have been adopted that might affect your project.
Compliance: Even in the absence of a permit, all work should be performed in accordance with generally accepted building standards to ensure structural integrity and safety.

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.
