Research notes
Indiana is a Home Rule + statutory-channel state (IC 36-1-3). Zoning power flows through IC 36-7-4 and any ordinance must follow the 500/600/800/900/1000 procedural framework. This overlay is procedural — it does not preempt substantive zoning fields directly, but a city ordinance that does not satisfy the 600/1000 Series is procedurally void. Townships hold no independent zoning authority (Dillon's Rule); they join the county area plan commission. Task brief referenced the '1000 Series' as the marquee enabling chapter — that is the enforcement/judicial-review group; substantive zoning is in the 600 Series. Both are captured in this single statutory-framework overlay so the citation lands precisely.
