Off-Grid Living in Randolph County, Indiana

Randolph County, Indiana is one of those places where I have to correct a common assumption: rural Indiana counties are often unzoned, but Randolph County is not one of them. The county's Area Planning & Zoning Department administers a countywide Unified Zoning Ordinance, so if you're eyeing raw land here for an off-grid setup, you're working within Ag Limited or Ag Intensive districts, not a regulatory blank slate.

Zoning and dwellings. The Area Planning Department reviews zoning changes through the Area Planning Commission, and agricultural districts have their own use tables. For homes, the county sets a minimum size for single-family homes, and in the ag districts you generally need at least two buildable acres for a new home or mobile home. Manufactured/single-wide homes need a specific Improvement Location Permit (ILP) application, and even portable sheds meant for habitation need one too. I could not confirm a specific county rule on using an RV as a permanent residence, so treat that as an open question for Area Planning to answer directly.

Building permits. Once Area Planning and the Surveyor's office sign off, the county Building Commission issues the actual building permit and handles inspections. Indiana's state building code (IRC-based) is the baseline; I found no confirmed local amendments.

Septic. The Health Department follows Indiana State Board of Health guidelines and runs its own On-Site Domestic Wastewater Treatment System Ordinance and permitting process, involving a certified soil scientist and registered contractor. Worth noting: the county flags "recessional moraine" soils in parts of Randolph County that may be unsuitable for standard septic systems. Composting toilets as a septic substitute aren't addressed anywhere I found, so that's not confirmed either.

Greywater and rainwater. Neither is specifically addressed in county sources. Greywater likely falls under the same wastewater ordinance as septic-regulated flows, but that's my inference, not a confirmed rule. Rainwater harvesting isn't prohibited anywhere I found, so it inherits the general state "permitted" baseline, though plumbing it into a house would trigger Building Commission code review.

Wells. Indiana requires well drillers to be licensed by the DNR under state law. Whether Randolph County's Health Department separately requires its own well-construction permit was not confirmed, since some Indiana counties do and some don't. Confirm directly.

Utilities. I found no county ordinance mandating hookup to electric, water, or sewer in the unincorporated county, so living off-grid appears permitted as long as you're square with septic and well rules. Important caveat: incorporated towns inside the county can and do set their own tap/hookup requirements, so this changes if you're inside town limits.

Bottom line: Randolph County is regulated but workable for off-grid living, with septic and zoning being your two real gatekeepers. Several details (RV occupancy, composting toilets, greywater, county well permits) just aren't spelled out publicly, so a phone call before you buy land will save you headaches.
