Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.
The local rulesJennings County, IN
Zoning & raw-land occupancy
RestrictedJennings County has adopted a countywide Zoning Ordinance administered by the Area Plan Commission and Zoning Enforcement Officer, so land use and occupancy are locally controlled rather than unregulated. source
Dwellings, tiny homes & RVs
Unclear - verifyNo county-specific rule on tiny homes, RVs as permanent dwellings, or minimum dwelling size was found; state law defines manufactured homes and gives counties zoning jurisdiction, but Jennings County's own standard is not confirmed. Ask the Area Plan Commission. source
Building permits & codes
RestrictedThe county maintains its own Building Code and permit process through the Area Plan Commission, requiring documents like a property card/deed and a septic permit before other approvals proceed. source
Septic & composting toilets
Generally allowedThe Jennings County Health Department's Septic Division administers the state's Residential On-Site Sewage Systems Rule (410 IAC 6-8.3) locally, including permits and inspections; composting/incinerating toilets have separate statewide ISDH guidance. source
Greywater reuse
Unclear - verifyNo Jennings County greywater ordinance was found; it defaults to the state OSS rule, which mainly separately addresses things like aerobic units, so greywater likely needs to go through a compliant septic system. Confirm with the county Health Department. source
Rainwater harvesting
Generally allowedNo Jennings County ordinance restricting rainwater harvesting was found, and there's no statewide prohibition, so this appears to default to permitted, with state plumbing code applying only if tied into household plumbing. source
Private wells & water rights
Generally allowedNo county-specific well ordinance was found; wells are governed by Indiana DNR's statewide well construction rules, though some parts of the county may fall inside regional utility districts worth checking before drilling.
Living disconnected from utilities
Varies locallyLiving without utility hookups is permitted in principle, but the county's building permit process asks about sewer district status, and parcels near incorporated towns or districts like Jennings Northwest Regional Utilities may need a formal waiver or release. source
