Building a barndominium in Johnson County: permits & land
Indiana's statewide residential code is the 2020 Indiana Residential Code (675 IAC 14-4.4), based on the 2018 International Residential Code. Building permits and inspections for houses are issued locally, by the city, town or county, not by the state. So for a parcel in Johnson County the questions are who issues the building permit, who issues the zoning permit, and who approves the septic system.
Who issues the permit
Johnson County Department of Planning and Zoning (Building Department), Franklin. The Johnson County Department of Planning and Zoning serves the unincorporated areas of the county: it enforces the zoning, subdivision and building codes and administers building permit and inspection services. Property inside a city or town limit, including Greenwood, is outside its jurisdiction and goes to that municipality. The department's stated average review time on a building permit application is 10 business days.
Zoning and land
Johnson County Department of Planning and Zoning. Under the Johnson County Unified Development Ordinance an improvement location permit (ILP) is required for all primary structures, accessory buildings, fences, decks, patios and slabs in the county's jurisdiction.
The Johnson County UDO's Agricultural (AG) district sets a 2-acre minimum lot, 200 feet of lot width, 25 percent maximum lot coverage, a 50-foot height limit and a 900-square-foot minimum dwelling size.
Septic and well
Johnson County Health Department, Environmental Division. The Environmental Division of the Johnson County Health Department oversees onsite septic construction, installation and abandonment, and publishes its list of registered septic contractors and soil specialists.

Floor plans for Johnson County builds
- Small Barndominium A small barndominium sized to the minimum house size your county's zoning sets — from 240 square feet in one Indiana district to 1,200 in another — with the state's tiny-house rules available below 400 square feet.
- 3-Bedroom Barndominium A three-bedroom barndominium planned around what Indiana's septic rule counts as a bedroom, so the den does not quietly become bedroom four.

- Modern Barndominium A modern barndominium — dark metal, big glass, low or shed roofs — checked first against the local design standards and covenants that decide whether that look is allowed on your lot.
- Barndominium with a Shop A barndominium with a shop under the same roof, planned around what the county's zoning lets the shop be used for — hobby, storage or a home business.
