Boone County Building and Safety Jurisdiction
In Boone County, Indiana, building permits and related construction oversight are managed by the Boone County Area Plan Commission (APC).

The office ensures that construction complies with the Boone County Zoning Ordinance, Building Regulations, and the Indiana Energy Code.
HVAC Permit Requirements for Unincorporated Areas
For properties located in the unincorporated areas of Boone County, HVAC work is regulated as part of the broader building permit process. HVAC systems must be designed and installed in accordance with applicable state codes, including the Indiana Energy Code. Key requirements include:
- Construction Plans: When applying for a building permit for new construction, additions, or major remodels, applicants must submit construction plans that include detailed HVAC, plumbing, and electrical layouts.
- Energy Efficiency: Projects must comply with the current Indiana Energy Code. This often requires the submission of an Energy Efficiency Certificate or an energy compliance report to ensure the mechanical systems and building envelope meet state standards.
- System Sizing: HVAC equipment must be sized according to industry standards, such as the ACCA Manual J (eighth edition).
- Inspections: All permitted work, including HVAC installations, is subject to inspections by the county building inspector. It is the responsibility of the applicant or contractor to schedule these inspections at the appropriate stages of construction.
- Permit Process: Applications and supporting documentation must be submitted to the APC office. If work begins without the required permit, the county may impose penalties, such as doubling the permit fee.

State-Level HVAC Building Codes in Indiana
In Indiana, building codes—including those governing heating, ventilation, and air conditioning (HVAC) systems—are established through the Indiana Administrative Code (IAC) under Title 675. These codes are developed and maintained by the Fire Prevention and Building Safety Commission. The state adopts model codes from the International Code Council (ICC) and incorporates specific Indiana amendments to address local requirements, climate conditions, and safety standards.
For residential construction, the state enforces the Indiana Residential Code, which is based on the International Residential Code (IRC). For commercial and other Class 1 structures, the state utilizes the Indiana Mechanical Code, which is based on the International Mechanical Code (IMC), alongside the Indiana Building Code and the Indiana Fuel Gas Code. Energy efficiency requirements for HVAC systems are governed by the Indiana Energy Conservation Code, which incorporates standards such as ASHRAE 90.1 for commercial applications.
Compliance with these codes is mandatory for new construction, additions, and major alterations. Enforcement is primarily handled by the Indiana Department of Homeland Security (IDHS) through its Division of Fire and Building Safety, in conjunction with local municipal and county building departments that oversee permitting and inspections.
Primary State Agencies
- Fire Prevention and Building Safety Commission: The primary body responsible for adopting, amending, and maintaining the state's building, mechanical, and energy codes.
- Indiana Department of Homeland Security (IDHS): The agency that administers and enforces these codes, including conducting plan reviews for Class 1 structures and providing guidance to local code enforcement officials.
