Illinois, McDonough County HVAC Permit Regulations and County Ordinances for Unincorporated Areas
McDonough County HVAC Permit Requirements
McDonough County, Illinois, does not appear to have a specific county-level Building & Safety Division that directly handles HVAC permit requirements for all properties within the county. Instead, permitting authority often resides with individual municipalities or townships, especially for properties within unincorporated areas.
For properties located in unincorporated areas of McDonough County, it is crucial to contact the relevant township or county officials to determine the specific HVAC permit requirements. These requirements can vary significantly depending on the specific location and the nature of the work being performed.
While Illinois does not mandate a state-level HVAC contractor license, individual municipalities and counties may have their own licensing or registration requirements for contractors. Additionally, federal regulations require EPA Section 608 certification for technicians working with refrigerants. Some local jurisdictions may also require specific permits for mechanical work, including HVAC installations and repairs.
It is recommended to contact the McDonough County Clerk's office or the relevant township office for guidance on permit requirements for unincorporated areas. For properties within incorporated cities or villages, such as Macomb, direct contact with the municipal building department is necessary.

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.
