Jefferson County, Illinois Roofing Permit Requirements
Jefferson County, Illinois, has a Building Department responsible for reviewing and approving all building plans to ensure construction meets current safety standards and building codes. This department plays a key role in maintaining construction quality and assists the public with building codes and regulations. Their mission is to protect and serve citizens through the enforcement of construction codes, zoning regulations, and safety standards.
A building permit is generally required for new structures, garages, and additions.

For specific questions regarding when a permit is needed, it is advisable to contact the Building Department directly.
While the provided information does not explicitly detail roofing-specific permit requirements, it indicates that permits are required for "new buildings, and additions."

Minor repairs or re-shingling may not necessitate a permit, but it is always best to confirm with the county.
For properties in unincorporated areas, the Jefferson County Building Department has jurisdiction. The county's Building Department is responsible for enforcing construction codes and zoning regulations throughout the county, including unincorporated areas.

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.
