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 rulesClark County, IN
Zoning & raw-land occupancy
RestrictedClark County has adopted countywide zoning via a Unified Development Ordinance, administered by the county Planning & Zoning office; unincorporated land is subject to zoning classification and setbacks. Incorporated towns/cities within the county (Jeffersonville, Charlestown, Sellersburg) have their own zoning departments. source
Dwellings, tiny homes & RVs
Unclear - verifyNo confirmed Clark County, Indiana source specifies tiny-home minimum size or RV-as-dwelling rules; a reference found for manufactured home/RV park standards turned out to be from a different state's Clark County and isn't reliable. Ask Planning & Zoning for the UDO's exact dwelling standards.
Building permits & codes
Generally allowedBuilding permits are issued through the Clark County Planning & Zoning office, which enforces the 2020 Indiana Residential Code; inspections require advance notice and larger projects go through the county's Citizenserve online system. source
Septic & composting toilets
Generally allowedSeptic systems are permitted through the Clark County Health Department's Environmental Health Division, consistent with the state's Rule 410 IAC 6-8.3 administered by the Indiana State Department of Health. source
Greywater reuse
Unclear - verifyNo Clark County-specific greywater rule was found; it likely falls under septic system requirements by default, but this isn't confirmed. Ask the Health Department's Environmental Health Division directly.
Rainwater harvesting
Generally allowedNo county ordinance restricting rainwater harvesting was found; any plumbing connection into a dwelling would fall under the residential code enforced by Planning & Zoning.
Private wells & water rights
Generally allowedNo county-specific well ordinance was found; private wells are regulated at the state level by the Indiana Department of Natural Resources under 312 IAC 13 and IC 25-39.
Living disconnected from utilities
Unclear - verifyNo explicit Clark County ordinance mandating utility hookup was found, but UDO occupancy conditions could indirectly require septic and water provision. Confirm directly with Planning & Zoning and the Health Department.
