Permit Requirements for Herscher, Illinois

For HVAC projects in Herscher, determining the correct permitting authority depends on whether the project site is located within the incorporated city limits or in an unincorporated area of Kankakee County.

Authority Having Jurisdiction (AHJ)

Most jurisdictions require permits for HVAC work to ensure safety and code compliance. The governing body responsible for issuing these permits varies by specific location:

General HVAC Guidelines

Permits are usually required for new installations, structural modifications, or major repairs. While minor maintenance or cosmetic updates may be exempt, landowners should always verify local codes before work begins.

Kankakee County HVAC Permit Requirements

In Kankakee County, Illinois, HVAC (heating, ventilating, and air conditioning) systems require a building permit. This applies to new installations, additions, renovations, and replacements of HVAC systems. The permits are necessary to ensure that construction meets minimum standards and that appropriate materials are used, thereby protecting public health, safety, and welfare.

The Kankakee County Planning Department's Building Division is responsible for issuing these permits. They adopt and enforce codes, standards, and ordinances related to building and safety.

Properties in Unincorporated Areas

Kankakee County issues building permits specifically for properties located in unincorporated areas of the county. If a property is within an incorporated city, that city's building department handles permit requirements, not the county.

For contractors performing work that requires a building permit in unincorporated Kankakee County, a contractor registration is mandatory before a permit can be issued. This registration program aims to protect the public and requires contractors to provide proof of insurance and a surety bond.

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.
