Primary-source summary
**Last reviewed**: April 2026 **Activity level**: **Moderate** — Indiana applies broad Home Rule to municipalities and counties (IC 36-1-3), but the General Assembly retains plenary authority and has layered several narrow preemptions onto the IC 36-7-4 "600 Series" zoning enabling act. Active preemptions cover short-term rentals (IC 36-1-24, strengthened by HEA 1210 of 2025), manufactured housing (IC 36-7-4-1106 and IC 36-7-2-12), and rental-rate / inclusionary-zoning controls (IC 32-31-1-20).

Research notes

Programmatic / financial overlay — NOT a zoning preemption. The 2023 enabling act is purely a state-funded incentive: it created the revolving fund and the 70/30 small-municipality allocation, but did NOT condition eligibility on land-use reforms (that came with HEA 1005 of 2025 — see IN_HEA1005_2025_RIF_PRIORITY_PRO_HOUSING). Brief mentioned 'HB 1005 (2023) ADU mandate' — verified against preemptions.md and IGA: HEA 1005 of 2023 is NOT an ADU mandate; it is the RIF infrastructure-loan vehicle. The ADU-by-right and other use-class preemptions arrived later with the opt-out framework in HB 1001 of 2026.
