Off-Grid Living in Warren County, Indiana

I've been digging into Warren County, Indiana for folks who want to live simply and quietly off the land, and the first thing I want to clear up is a misconception: this county is NOT a "no zoning" haven. Warren County has an adopted Joint Zoning Ordinance, shared with the municipalities inside its borders, administered by the Warren County Area Plan & Zoning Office. That office issues building permits, handles variances and special exceptions, and does site inspections. So if you're picturing dropping a camper on bare land and disappearing, you'll want to adjust that picture.

On dwellings specifically, the ordinance text is blunt: sheds, mobile homes, buses, travel trailers, RVs, and shipping containers are not permitted as residential units unless they're modified to meet building code and other applicable regulations. That language shows up repeatedly across the residential zoning districts (Two-Family, Rural Residential, Residential Estate). A tiny house built to code on a permanent foundation would likely count as a conforming dwelling, but I haven't found anything from the county confirming tiny-home specifics beyond that general reading of the ordinance, so treat that as an open question for the zoning office. I also saw a claim floating around about a specific ADU ordinance amendment, but that only appears on a commercial blog, not an official county source, so I'm not counting it.

Building permits and inspections run through that same Area Plan & Zoning Office, working off Indiana's statewide residential code baseline.

For sewage, the Warren County Health Department administers septic permitting under Indiana's statewide onsite sewage rule, and installers need to be certified. Composting toilets aren't addressed separately on the county's page, so I'd assume the state's general approach applies (permitted, but you'll likely still need an approved system for any wastewater).

Greywater and rainwater harvesting: I found nothing county-specific on either. No ordinance banning either practice was found either, so it looks like Indiana's general baseline carries you here, but you should still ask Environmental Health directly since these are the kinds of things that get decided informally at the local level.

Wells are licensed at the state level through Indiana DNR, and the county Health Department's Environmental Health division typically handles local approval, working with ISDH guidance. I didn't find a distinct fee schedule or process page from Warren County itself, so a phone call is your best bet.

Finally, on living disconnected from utilities altogether, I found no Warren County ordinance forcing a hookup to electric, water, or sewer. But remember, the septic and building-permit rules still apply to any structure you intend to live in, so "off-grid" doesn't mean "off the radar" here.
