County-Level Jurisdiction: The LaPorte County Building Department handles permit issuance for the entire county.
Unincorporated Areas: For properties in unincorporated areas, contractors must obtain a contractor's registration permit before undertaking any construction or alteration work, including HVAC installations. This registration requires proof of liability insurance, worker's compensation or waiver, and a $10,000 bond payable to LaPorte County Unincorporated.
Permit Application: A permit is required before beginning any construction or alterations that involve the installation of new heating or air conditioning systems.
Contractor Registration: Any individual or entity engaging in the business of heating, ventilation, and air conditioning (HVAC) in LaPorte County must first obtain a contractor's registration permit. This registration involves an application process, payment of a fee, and submission of required documentation, including insurance and bonding for unincorporated areas.
Required Documentation for Unincorporated Areas: For new residential construction in unincorporated LaPorte County, specific documents are required prior to permit issuance, which would include HVAC work. These include obtaining an address and driveway permit, well and septic permits (or utility authorization), a floor plan and foundation print, and potentially an elevation certificate if in a flood plain. All subcontractors must also be registered, insured, and bonded.
Inspections: HVAC installations will be subject to inspections. The contractor or owner must call the Plan Commission office in advance to schedule these inspections.

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.
