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

HVAC Permit Requirements in Howard County, Indiana

For properties in unincorporated areas of Howard County, it is essential to contact the relevant county departments for specific permit requirements, as these can vary. Generally, HVAC permits are required for new installations or replacements of furnaces, air conditioning units, and other heating or cooling equipment.

In Kokomo, which is the county seat of Howard County, a mechanical permit is required for replacing an HVAC system with the same type, installing a different type of HVAC system, modifying or installing ductwork, or adding central HVAC to a home. These permits are typically obtained from the Wastewater Utility Office, located on the first floor of City Hall.

Permit fees in Kokomo can range from $50 to $125 for a mechanical permit, with more complex projects costing more. Working without a required permit can result in fines, stop-work orders, and complications when selling a property.

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.
