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 rulesRandolph County, IN
Zoning & raw-land occupancy
RestrictedRandolph County has countywide zoning under its Unified Zoning Ordinance, administered by the Area Planning & Zoning Department; agricultural districts govern most rural land use. source
Dwellings, tiny homes & RVs
RestrictedSingle-family homes must meet a minimum size set by the county, and ag-district homes generally need at least two buildable acres; manufactured homes and habitable sheds need a specific Improvement Location Permit. RV-as-permanent-dwelling rules are not confirmed. source
Building permits & codes
RestrictedThe county Building Commission requires a building permit and inspections after zoning approval, following Indiana's state building code baseline; no local code amendments were confirmed. source
Septic & composting toilets
RestrictedThe Randolph County Health Department requires septic permitting through soil analysis and a registered contractor under the county's wastewater ordinance and Indiana State Board of Health guidelines; some county soils are flagged as unsuitable. source
Greywater reuse
Unclear - verifyNo Randolph County or Indiana state rule specifically addressing residential greywater reuse was found; it likely falls under the same wastewater ordinance as septic but this is not confirmed. Ask the Health Department.
Rainwater harvesting
Unclear - verifyNo county ordinance addressing rainwater catchment was found, so it appears to inherit the general permitted state baseline; plumbing it into a house would fall under Building Commission code review. source
Private wells & water rights
Varies locallyIndiana state law requires DNR-licensed well drillers for all wells; whether Randolph County's Health Department separately requires a well-construction permit was not confirmed and should be checked directly. source
Living disconnected from utilities
Generally allowedNo countywide ordinance mandates utility hookup for unincorporated land, so off-grid living is permitted there subject to septic and well compliance; incorporated towns within the county may impose their own hookup rules. source
