Massac County, Illinois Roofing Permit Regulations and County Ordinances for Unincorporated Areas
Building and Safety Jurisdiction in Massac County
Massac County does not have a centralized county-level building department that manages general building permits for all projects. Because permitting requirements can vary significantly depending on the specific location of your property, it is essential to contact the Massac County Clerk’s office directly to determine if a permit is required for your specific roofing project.
Roofing Requirements in Unincorporated Areas
For properties located in unincorporated areas of Massac County, there is no universally confirmed county-wide general building permit program. However, property owners must still ensure compliance with applicable state standards. As of January 1, 2025, construction in unincorporated areas of Illinois must meet the minimum standards established by Public Act 103-0510, which includes the International Residential Code (IRC) and other relevant state codes. Additionally, while a general building permit may not be required by the county, you must ensure that any contractor hired for roofing work holds a valid Illinois roofing license, as required by state law for roofing and waterproofing 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.
