Indiana Agricultural Zoning and Local Authority

Indiana's local planning and zoning authority is granted under IC 36-7-4, the 600 Series, allowing counties and cities to adopt zoning ordinances. However, IC 36-7-4-616 historically limited zoning regulation of agricultural land uses on parcels above certain thresholds, and counties commonly designate agricultural districts permitting CAFOs and traditional farming. Local governments must coordinate with the Indiana Right to Farm Act to avoid impairing protected agricultural operations under IC 32-30-6-9. Some county ordinances impose setback, manure management, and odor controls on confined feeding operations beyond IDEM permits, when consistent with state law.

Zoning that conflicts with the Right to Farm Act or improperly restricts protected agricultural use may be invalidated by courts upon legal challenge.
