Vigo County HVAC Permit Requirements
In Vigo County, Indiana, HVAC permit requirements are handled at the county level for unincorporated areas.

Indiana does not have statewide HVAC licensing. Instead, licensing and permit requirements are determined by local jurisdictions, including cities and counties. Contractors may need to meet specific local requirements, which can include passing local exams, demonstrating experience, and providing proof of insurance.
Rules for Properties in Unincorporated Areas
For properties located in unincorporated areas of Vigo County, the Vigo County Building Inspections Department is the relevant authority for issuing permits and enforcing building codes. This department handles Building, Electric, Plumbing, and Demolition permits. For any construction that adds square footage, an "Improvement Location Permit" is required, which involves a three-step process with the Area Planning Department and the Vigo County Board of Health Department.
The Vigo County Area Planning Department also plays a role in the permitting process, particularly for zoning and subdivision control ordinances. They have a set timeframe of five business days to grant a permit, though additional time may be needed by other departments.

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.
