Illinois, Pulaski County HVAC Permit Regulations and County Ordinances for Unincorporated Areas
Pulaski County HVAC Permit Requirements
Pulaski County, Illinois, issues building permits for properties located in unincorporated areas of the county. If your property is within an incorporated city, that city's building department will handle permit requirements. Illinois does not have statewide HVAC licensing; therefore, local jurisdictions manage their own licensing requirements. Federal EPA certification is necessary for refrigerant handling.
For HVAC permit applications, you will generally need to submit a completed application form, provide details of the work being performed, and include specification sheets for materials and equipment. If equipment is being relocated, drawings showing the new locations are required. Two inspections are typically necessary: a rough HVAC inspection and a final HVAC inspection.
It is important to note that specific requirements and fees can change. It is recommended to confirm current regulations directly with the relevant county department before beginning any work.
Rules for Properties in Unincorporated Areas
Pulaski County is responsible for issuing building permits for properties situated in unincorporated areas of the county. For any property within an incorporated city, the respective city's building department is the authority for permits. This means that for HVAC projects in unincorporated areas of Pulaski County, you will need to go through the county's Building Department.

State-Level Building Codes and Legislation for HVAC in Illinois
In Illinois, the regulatory landscape for building codes, including HVAC requirements, has historically been decentralized, with local units of government (cities and counties) having the authority to adopt and enforce their own building codes. However, this is transitioning toward a more standardized statewide framework.
The most significant statewide mandate regarding HVAC systems is the Illinois Energy Conservation Code. Under the Energy Efficient Building Act (20 ILCS 3125), the state is required to adopt the latest published edition of the International Energy Conservation Code (IECC), typically with specific Illinois amendments. As of recent updates, Illinois has adopted the 2021 IECC. This code establishes mandatory minimum efficiency standards for HVAC equipment, ductwork, and system design for both new construction and major renovations in residential and commercial buildings.
Regarding general mechanical and structural codes (such as the International Mechanical Code or International Residential Code), Illinois has historically allowed local jurisdictions to choose their own standards. However, legislation (Public Act 103-0510) has been enacted to implement a statewide building code effective January 1, 2025. Under this new framework, local codes must regulate structural design in a manner at least as stringent as the International Building Code (IBC) for new commercial buildings or the International Residential Code (IRC) for residential buildings.
It is important to note that Illinois does not issue a statewide license for HVAC contractors or technicians. Licensing, permitting, and inspection requirements are handled entirely at the local municipal or county level. Professionals must verify the specific requirements of the jurisdiction where the work is being performed.
Primary State Agencies
- Illinois Capital Development Board (CDB): The primary agency responsible for adopting and updating the Illinois Energy Conservation Code and overseeing the transition to statewide building code standards.
- Illinois Department of Public Health (IDPH): Responsible for specific codes related to public health, such as the Illinois Plumbing Code, which can intersect with HVAC installations (e.g., condensate drainage).
- Office of the Illinois State Fire Marshal: Oversees fire prevention and safety rules, which include standards relevant to mechanical and fuel gas systems.
