How the local permit process works

Start with Hancock County Health Department — Environmental Health. Before ordering excavation, design, or installation work, use the county’s current application materials and confirm the required soil/site evaluation, plan format, fee, and inspection sequence for the specific property.

Indiana also maintains statewide residential onsite sewage rules through the Indiana Department of Health. Local pages can impose additional administrative steps or local ordinances, so both levels matter.

Do not treat a county guide as parcel approval. Soil conditions, sewer availability, wells, lot configuration, setbacks, design flow, and prior permits can change the answer for an individual property.
