39.4174, -86.4082Read this before you act on anything below. This is my researched starting point for Morgan 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 rulesMorgan County, IN
Zoning & raw-land occupancy
RestrictedMorgan County has countywide zoning through its Advisory Plan Commission and Unified Development Ordinance (UDO), effective 1-1-22, so raw land in unincorporated areas is regulated, not a free-for-all. Incorporated towns like Martinsville and Mooresville have their own separate codes I haven't dug into here. source
Dwellings, tiny homes & RVs
RestrictedIndiana's statewide residential code applies, and a commercial (non-official) source says Morgan County requires permits and inspections for occupancy, but exact tiny-home minimums aren't confirmed from an official source. RVs as full-time residences outside campgrounds are treated cautiously under Indiana's typical UDO pattern, but this isn't confirmed specifically for Morgan County, so I'd call Planning & Zoning before you buy anything on wheels. source
Building permits & codes
RestrictedThe Planning and Zoning Department issues building permits and does inspections, floodplain review, and 911 addressing for unincorporated Morgan County, applying Indiana's statewide residential code. source
Septic & composting toilets
RestrictedAny home not on sewer needs a septic permit through the Morgan County Health Department's Environmental Health Division, following state rule 410 IAC 6-8.3 and a county ordinance, with a site inspection required before issuance and installers needing a county license. I found no official word on composting toilets as a stand-alone substitute, so ask the Health Department directly if that's your plan. source
Greywater reuse
Unclear - verifyI couldn't find a Morgan County or Indiana state page specifically addressing greywater reuse. It appears to fall under the same onsite sewage rules as other wastewater, but there's no confirmed separate greywater permit or exemption, so check with the Morgan County Health Department's Environmental Health Division before setting anything up.
Rainwater harvesting
Unclear - verifyNo Morgan County ordinance or health department page on rainwater harvesting turned up in my research, and I found no state prohibition either, so this looks fine by default but isn't officially confirmed one way or the other. Worth a quick call to Planning & Zoning if you want certainty.
Private wells & water rights
Generally allowedOrdinary domestic wells don't need a permit under Indiana DNR rules; only high-capacity wells (pumping at least 100,000 gallons a day) require registration as a Significant Water Withdrawal Facility with DNR's Division of Water. I didn't find a Morgan County health department page on well permitting, so well construction and driller licensing appear to be handled at the state level. source
Living disconnected from utilities
Unclear - verifyI found no official Morgan County page requiring hookup to public electric, water, or sewer utilities, so living disconnected appears permitted at the county level by default. A town or utility district within the county could still have its own mandatory-hookup rule, which I haven't confirmed, so check locally if you're near a town line.
