Off-Grid Living in Shelby County, Indiana

I've been digging into what off-grid living actually looks like in Shelby County, Indiana, and the first thing to get straight is geography. If your land is in the unincorporated county, the Shelby County Plan Commission and Shelby County Building Inspector are your authorities. If you're inside Shelbyville, Fairland, Morristown, Edinburgh, or St. Paul, the city/town (or, for St. Paul, the Decatur County Area Plan Commission) governs instead, not the county. This brief is written for the unincorporated county baseline.

Zoning: Shelby County adopted a Unified Development Ordinance under its authority from Indiana state law (IC 36-7-4), so unlike some rural counties, this one does have countywide zoning for unincorporated land, with agricultural, rural residential, and other districts. Districts don't nest into each other, so what's allowed in one ag district isn't automatically allowed in another. Land in flood hazard areas needs a separate Floodplain Permit, and anything in the actual Floodway needs sign-off from the Indiana DNR Division of Water too.

Dwellings, tiny homes, RVs: Any new structure over 200 square feet needs an Improvement Location Permit from the Plan Commission. Manufactured homes placed outside their standard districts have needed a Board of Zoning Appeals use variance, plus a full slate of permits (site plan, building, electric, plumbing, septic). Worth flagging: those use variances expire when the property sells, so a future owner would have to remove the home or get a new variance. I couldn't confirm a specific minimum dwelling size or a blanket RV occupancy rule in the county's ordinance text, so treat RV living as recreational-use-only until you confirm directly with the Plan Commission.

Building codes: The county follows the Indiana State Building Code, enforced locally by the Shelby County Building Inspector, covering the unincorporated county and the Town of Fairland.

Septic and greywater: The Shelby County Health Department's Environmental Division issues septic (onsite sewage) permits, implementing the state's 410 IAC 6-8.3 rule locally. I found nothing specific on composting toilets as a septic substitute or on greywater reuse rules for the county, so both are unclear, and I'd call the Environmental Division directly before assuming either is allowed.

Rainwater: No county rule found either way. State plumbing code, enforced by the county Building Inspector, would apply if you're plumbing harvested water into a house.

Wells: Wells fall under the state's driller-licensing framework (IC 25-39 / 312 IAC 13), and the county Health Department offers water testing services and fields complaints like abandoned wells. No separate county well-permit ordinance was confirmed.

Off-grid utilities: I found no county mandate to hook up to public electric, water, or sewer in unincorporated areas, so living disconnected looks permitted there as long as your septic, well, and building permits are in order. Shelbyville and other towns may have their own mandatory-hookup rules, which this brief doesn't cover.

Bottom line: the county has real zoning and permitting teeth, so plan on paperwork, but off-grid living itself isn't banned in the unincorporated area.
