38.7824, -85.3788Read this before you act on anything below. This is my researched starting point for Jefferson County, IN, not legal advice and not a guarantee. 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 rulesJefferson County, IN
Zoning & raw-land occupancy
Varies locallyJefferson County has countywide zoning through a Unified Development Ordinance administered by the Planning, Zoning & Building Inspection Department, with districts including Agricultural, Residential, Business, Industrial, Environmental, and Flood Hazard. The ordinance was under active update as of 2021, so confirm current requirements with the county. source
Dwellings, tiny homes & RVs
RestrictedThe county's own guidance says RVs cannot be used as permanent residences outside a licensed campground or approved RV park, and occupancy beyond 14 consecutive days requires an approved campground. Manufactured homes and tiny homes on permanent foundations are treated as regular dwellings subject to county building and zoning rules. source
Building permits & codes
RestrictedJefferson County requires building permits and inspections, and requires proof of septic approval before plumbing work on properties not connected to municipal sewer. The specific IRC edition/local amendments in force were not confirmed in this research. source
Septic & composting toilets
Generally allowedThe Jefferson County Health Department issues onsite sewage permits following the Indiana State Department of Health's statewide rule (410 IAC 6-10.1), and requires a certified contractor, site plan, and soil test. Composting toilets are not separately addressed on official county pages, so that's not confirmed. source
Greywater reuse
Unclear - verifyNo Jefferson County ordinance specifically addressing greywater reuse was found; it's likely folded into the state onsite sewage rule by default. Confirm directly with the Jefferson County Health Department.
Rainwater harvesting
Unclear - verifyNo county ordinance addressing rainwater harvesting was found, and there's no known statewide prohibition, but this is not confirmed for Jefferson County specifically. Ask the Planning, Zoning & Building Inspection Department before relying on this.
Private wells & water rights
Unclear - verifyNo Jefferson County-specific well permitting ordinance was found; well construction appears to fall under the state's driller licensing framework rather than a distinct county permit, but this was not confirmed. Confirm with the county and the state well program.
Living disconnected from utilities
Generally allowedThe county's building permit process explicitly contemplates properties not connected to municipal sewer, and no ordinance requiring mandatory electric or water utility hookups was found, so off-grid living tied to a septic permit appears to be lawful. source
