41.3631, -86.3294Read this before you act on anything below. This is my researched starting point for Marshall 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 rulesMarshall County, IN
Zoning & raw-land occupancy
RestrictedMarshall County has countywide zoning administered by the Planning Department and Plan Commission, requiring an Improvement Location Permit before building or changing land use in unincorporated areas. Towns like Plymouth, Argos, Bourbon, Bremen, and Culver have their own separate zoning. source
Dwellings, tiny homes & RVs
Varies locallyRVs used as residences outside licensed parks may trigger special-use or nuisance rules under county zoning; state law bars counties from banning manufactured homes over 950 sq ft used permanently, but no county tiny-home minimum was confirmed. source
Building permits & codes
RestrictedThe Marshall County Building Commission enforces the 2018 IRC and IBC in unincorporated areas; owner-occupants can do their own construction work without contractor registration, but hired contractors must register. source
Septic & composting toilets
Generally allowedThe county Health Department issues onsite sewage permits under state Rule 410 IAC 6-8.3, requiring a certified soil scientist evaluation before approval. Composting toilets as a sole system are not addressed in retrieved county materials. source
Greywater reuse
Unclear - verifyNo Marshall County ordinance or health department guidance on greywater reuse was found; ask the county Health Department directly since septic rules cover general sewage but don't clearly address greywater separately.
Rainwater harvesting
Unclear - verifyNo county-specific rule on rainwater harvesting or cisterns was found; any tie-in to household plumbing would likely fall under the state plumbing code as enforced by the county Building Department, but this isn't confirmed.
Private wells & water rights
Generally allowedMarshall County's Health Department states there is no county-specific well code beyond requiring wells be 50 feet from septic systems; well construction otherwise follows state DNR rules, with IDEM overseeing public and semi-public supplies. source
Living disconnected from utilities
Generally allowedNo Marshall County ordinance requiring connection to public electric, water, or sewer utilities was found; septic is required only when not on public sewer, following the state baseline.
