Tiny Homes in Indiana

Indiana offers a practical environment for tiny home living, with no statewide minimum square footage and early adoption of IRC Appendix Q in 2019 for foundation-built tiny homes under 400 square feet. The state’s regulatory landscape is decentralized — county and municipal governments set their own zoning rules, which means opportunities vary widely depending on location. Rural counties tend to be the most permissive, while cities like Indianapolis and South Bend have specific minimum size requirements for residential zones.

Where to Place a Tiny Home in Indiana

Indiana’s “Log Cabin Rule” allows property owners to build small structures on their own land, though modern tiny homes typically require full code compliance. For foundation-built tiny homes, Indianapolis permits units as small as 400 square feet in residential zones, and South Bend allows similar sizes across most residential districts. Rural counties — particularly in southern Indiana and along the Kankakee River corridor in the northwest — offer the most flexible placement options with lower costs.

Sage Valley Ecovillage in Worthington is a registered nonprofit intentional community focused on sustainable living, with residents living in small structures on shared land. In northwest Indiana, the Lomax Tiny House Community offers half-acre lots on 34 gated acres near the Kankakee River, surrounded by over 20,000 hand-planted trees. Circle City Village in Indianapolis, developed by Sanctuary Indy, is a permanent supportive tiny home community serving chronically homeless individuals, with Phase I providing six homes and Phase II planned to include duplexes and a community center.

Indiana Tiny Home Builders

Timeless Tiny Homes in Brownsburg builds custom tiny homes, ADUs, granny flats, and garage conversions ranging from 220 to 1,200 square feet, with custom models under 400 square feet starting at $50,000 to $100,000. Utopian Villas in McCordsville specializes in luxury park model tiny homes with high-end finishes and appliances, with models starting at $121,000 to $174,000. Both builders are based in the Indianapolis metro area and serve clients statewide.

For RVIA-certified park models, Zook Cabins delivers to Indiana from their Pennsylvania manufacturing facility, with units built to ANSI A119.5 standards. Great Lakes Tiny Homes, based in Michigan and Ohio, is a full-service manufacturer of modular, park model, and tiny homes delivering turnkey builds across the lower 48 states, with options for RVIA certification.

Key Regulations to Know

Indiana adopted IRC Appendix Q on December 31, 2019, which applies to foundation-built dwellings of 400 square feet or less. The appendix sets standards for ceiling heights, loft dimensions, emergency escape openings, and stairway/ladder access. This provides a clear code pathway for tiny homes built on permanent foundations in jurisdictions that enforce the state building code.

THOWs are classified as recreational vehicles under Indiana law and are generally subject to RV parking restrictions, including limits on how long they can remain on a single property. RVIA certification (ANSI A119.5) is recommended for THOWs to ensure legal registration with the Indiana BMV and acceptance at RV parks. NTA, Inc. in Nappanee, Indiana provides testing and certification services for manufactured and modular housing units.

HB 1005, signed into law in 2025, streamlined building permit inspections across Indiana by allowing private inspection providers for residential construction. While not tiny-home-specific, this law reduces permit processing times and removes the requirement for architect-prepared documents for code-compliant residential builds — both of which benefit tiny home builders and owners.

Note: Indiana does not have statewide ADU legislation as of April 2026. ADU rules are set locally. Indianapolis, Zionsville (updated 2025), and Vanderburgh County have adopted their own ADU provisions. Check with your municipality for current rules.
