Tiny Homes Zoning — State ProfileReviewed 2026-08-23
Can you put a tiny home in Indiana?
Current tiny-home-on-wheels and ADU rules for Indiana, sourced and dated — plus verified local builders.
GENERALLY ALLOWED
Indiana — Generally permissive, rural-heavy, with a real named example (verified 2026-08)
Tiny home on wheelsNo statewide tiny-home-on-wheels law; the state's Residential Code (IRC-based) defines a tiny home as 400 sq ft or less with a 6'8" minimum ceiling height, but placement and full-time occupancy are entirely local questions. Rural Indiana counties are generally more permissive, consistent with the broader Midwest pattern.
ADU / accessory unitThis upgrades an earlier thin draft with a real example: the Indianapolis–Marion County Unified Development Ordinance (UDO) allows detached ADUs up to 900 sq ft, with no owner-occupancy requirement and no impact fees. Indiana has no statewide ADU preemption law — every other city and county sets its own rules independently.
Minimum square footageStatewide Residential Code defines a tiny home as 400 sq ft or less; local minimums vary above that
Foundation requirementFoundation-built units follow the state Residential Code; wheeled units are generally treated as RVs and limited to temporary use
Local notesYou may see Indiana's rural flexibility referred to informally as a 'Log Cabin Rule' in some secondary sources — that framing wasn't independently corroborated here and should be treated as informal shorthand, not a cited statute.
!Zoning is set by your specific city or county, not the state as a whole. Use this as a starting point, then confirm with the local building or planning department before you buy land or start a build. Not legal advice.
