Indiana, Pulaski County HVAC Permit Regulations and County Ordinances for Unincorporated Areas

Pulaski County, Indiana HVAC Permit Requirements

Pulaski County, Indiana, handles building permits and inspections through its Building Department. This department is responsible for protecting the life, public safety, health, and general welfare of the county's citizens. They also have joint agreements with the municipalities of Winamac, Monterey, and Medaryville, meaning the county department handles permits for these areas as well.

For properties located in unincorporated areas of Pulaski County, the County Building Department issues the necessary permits. If a property is within an incorporated city, that city's building department is responsible for permits, not the county.

To obtain an HVAC (Mechanical) permit, an application must be submitted, agreeing that all work will comply with current state and local regulations. Homeowners performing their own work are required to submit a Homeowner's Affidavit. Applications are processed in the order they are received, and applicants will be notified upon approval. Inspections typically require a 24 to 48-hour notice.

The Pulaski County Building Department enforces the adopted building codes for the State of Indiana.

Footings prior to placement of stone or concrete.

Indiana Hvac Legislation, Codes, and Guidelines

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.
