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 rulesDearborn County, IN
Zoning & raw-land occupancy
Varies locallyDearborn County has countywide zoning (Agricultural and Residential districts) administered by the Plan Commission, unlike unzoned Indiana counties. Raw-land use depends on district rules, which the county has reportedly been discussing updating. source
Dwellings, tiny homes & RVs
RestrictedCounty ordinances haven't been updated for newer housing types like tiny homes, so permanent use likely needs a variance, conditional use, or rezone from Planning & Zoning; RV-as-dwelling treatment is not confirmed officially. source
Building permits & codes
Generally allowedIndiana sets the state residential code, but the Dearborn County Building Department locally enforces permits and inspections for one- and two-family homes. source
Septic & composting toilets
Generally allowedThe Dearborn County Health Department's Environmental Division issues onsite sewage permits under state authority and requires use of an Indiana-recognized soil scientist during review. source
Greywater reuse
Unclear - verifyNo Dearborn County or Indiana state page specifically addresses greywater reuse separate from septic rules; likely folded into onsite sewage regulation but not confirmed. Ask the county Health Department's Environmental Division.
Rainwater harvesting
Unclear - verifyNo Dearborn County ordinance addressing rainwater harvesting was found; it appears to fall under the state baseline with no specific prohibition, but this is not confirmed. Confirm with Planning & Zoning or the Building Department.
Private wells & water rights
Generally allowedWell construction is governed by Indiana DNR rules; the county Soil & Water Conservation District offers testing referrals and DNR maintains hydrogeologic maps of the county. source
Living disconnected from utilities
Unclear - verifyNo county ordinance mandating utility hookup was found, but whether the Regional Sewer District requires connection for nearby parcels is not confirmed and should be asked directly. source
