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

Cumberland County Building and Safety Jurisdiction

In Illinois, building permit requirements are highly localized, as there is no centralized state-wide permitting authority. Cumberland County does not maintain a centralized county-wide building department that enforces a uniform building code for all areas. Instead, regulatory authority is typically fragmented among individual municipalities (cities, villages, and towns) and, in some cases, specific township regulations.

Rules for Properties in Unincorporated Areas

Properties located in unincorporated areas of Cumberland County often have fewer building permit requirements compared to those within incorporated municipal limits. However, this does not mean there are no regulations. Even in unincorporated areas, you may be subject to:

Zoning and Land Use: While the county may not enforce a comprehensive building code, it may have zoning ordinances or land-use policies that dictate where and what type of structures can be built.
State-Level Requirements: Regardless of local permit requirements, all roofing contractors in Illinois are required by state law to hold a valid roofing license issued by the Illinois Department of Financial and Professional Regulation.
Specific Local Ordinances: Some townships within the county may have their own specific requirements for construction, accessory structures, or safety standards.
Due Diligence: Because requirements vary significantly by location, it is essential to contact the Cumberland County Clerk’s office or the specific township office where your property is located to verify if a permit is required for your specific 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.
