What Are Indiana Impact Fees?
Indiana permits impact fees only through the structured process in IC 36-7-4-1300 et seq., which limits them to specific infrastructure categories — parks and recreation being the most commonly adopted — and requires a zone improvement plan. Water and sewer system development or availability charges from utilities carry much of the remaining load.
Hamilton County's fast-growing suburbs north of Indianapolis are the state's most active fee adopters. Indiana figures on impactfees.org are model estimates calibrated to community size and state cost factors; confirm current ordinances with each city or town.
Indiana figures are illustrative estimates from our statewide cost model — calibrated to local construction costs and community size — rather than verified fee schedules. Use them for early budgeting and site comparison, and see our methodology for how estimates are built.
