Off-Grid Living in Warrick County, Indiana

I've been digging through Warrick County, Indiana's official sources to figure out what off-grid living actually looks like here, and the short version is: this is a zoned county, which changes the picture compared to places with no zoning at all.

Zoning. The Warrick County Area Plan Commission administers a countywide Comprehensive Zoning Ordinance (amended as recently as 2025) covering the unincorporated county plus Elberfeld, Lynnville, and Tennyson. Boonville, Chandler, and Newburgh may run their own local codes on top of this. What you can do with raw land, camp on it, park an RV, build a small cabin, depends on which zoning district your parcel sits in. There's no blanket "anything goes" rule here; you need to check your district with the Area Plan Commission before you buy or build.

Dwellings, tiny homes, RVs. I couldn't find a Warrick County ordinance spelling out minimum square footage for dwellings, tiny-home standards, or whether an RV can be a permanent residence. Indiana's manufactured home statute limits how far local aesthetic rules can reach into manufactured-home foundations, but the county-specific dwelling-type provisions weren't in the official text I could access. This is a call-the-office item.

Building permits. This one's confirmed and specific: the Warrick County Building Commission requires a permit before construction when a project exceeds certain cost or size thresholds (the county code names $2,500 in construction value, 120 square feet, or $750 for electrical/plumbing/mechanical work as triggers). Don't take my summary as the final word, read the actual code section, but plan on a permit for almost anything beyond a small shed.

Septic and composting toilets. Indiana delegates septic permitting to local health departments statewide, and that appears to hold in Warrick County too, though I didn't find a distinct county ordinance text (unlike some neighboring counties). The Indiana Department of Health publishes guidance specifically covering composting and incinerating toilets in single-family homes. Confirm local forms and any add-on rules with the Warrick County Health Department.

Greywater, rainwater, wells, utility hookups. None of these have a distinct Warrick County ordinance that I could locate. Rainwater harvesting appears unrestricted and would just fall under normal plumbing code if you tie it into house plumbing. Wells are a state (not county) matter. I found nothing requiring you to hook up to public utilities, but absence of a rule I could find isn't the same as confirmation there isn't one, so I'd verify directly.

Bottom line on honesty here: Warrick County actively zones and actively requires building permits, that part is solid. But several of the specifics that matter most for off-grid plans, dwelling minimums, greywater, wells, aren't spelled out in the official sources I could reach. Call before you commit to a plan.
