However, replacing a water heater with one identical in venting and fuel type, or extending heating or cooling ductwork, may be exceptions. It is crucial to verify specific compliance needs with the local building department, as local jurisdictions may have additional requirements beyond state energy codes.
The authority having jurisdiction for building permits in Indianapolis is the Department of Business and Neighborhood Services (DBNS). For HVAC contractors, a license is required to perform work in the Indianapolis area, and it is against the law to do so without the proper license and permit.
Zoning and Fee Nuances
While specific zoning ordinances directly impacting HVAC installations are not detailed in the provided search results, HVAC and mechanical equipment are mentioned in relation to building height regulations, where they may extend above maximum building heights if properly screened. Additionally, HVAC zoning, which refers to controlling temperature in different areas of a home, is a service offered by HVAC companies, but not directly tied to municipal permit ordinances in the provided information.
Regarding fees, the City of Indianapolis has a fee schedule for permits, which was updated as of January 5, 2026. Craft permits, including those for HVAC, did not change in price. Specific fees for HVAC permits can be found in the building and construction fee schedule. For example, new unit heat permits are priced per BTU, and there are fees for repairs and replacements. A potential fee reduction may apply if heating and air conditioning are installed or replaced simultaneously in a one- or two-family dwelling.
It is important to note that permit fees and application processes can vary by project type, size, and whether plan review is required. For detailed breakdowns and the most current fee schedule, it is recommended to consult the city's official website or contact the DBNS directly.
