40.2223, -87.3353Read this before you act on anything below. This is my researched starting point for Fountain 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 rulesFountain County, IN
Zoning & raw-land occupancy
RestrictedFountain County has a countywide zoning ordinance requiring an Improvement Location Permit for structures in Business, Residential, Landfill, and Industrial districts, administered by the county's Plan Commission. There's no county inspector right now, so enforcement is complaint-driven rather than proactive, but if you're in one of the six incorporated towns or their fringe (like Attica or Covington's 2-mile fringe), you'll fall under that town's own, sometimes stricter, rules instead. source
Dwellings, tiny homes & RVs
Varies locallyI couldn't confirm any Fountain County-specific minimum-size rule for tiny homes on an official source, so claims of a specific square-footage threshold aren't verified. Indiana state law limits how restrictive local rules can be on manufactured homes over 950 sq ft, and it's not confirmed whether the county ordinance text has a specific written RV-occupancy limit, so I'd call the Zoning Administrator before assuming either way. source
Building permits & codes
RestrictedA building permit is required for new construction in regulated zoning districts, obtained through county staff, but the county currently has no building inspector and only does complaint-based investigations rather than routine inspections. source
Septic & composting toilets
Generally allowedSeptic is allowed and required for any property not on municipal sewer, with permits issued by the Fountain County Health Department under the statewide technical standard in 410 IAC 6-8.3. Installers must be IOWPA certified or separately approved, and a certified soil scientist's soil test must be on file before a permit is issued. Composting toilets aren't separately addressed on the county site, so that's not confirmed, ask the Health Department directly. source
Greywater reuse
Unclear - verifyI found no Fountain County-specific greywater rule. It would presumptively run through the same onsite sewage system permitting the Health Department handles under the state's 410 IAC 6-8.3 rule, but that's my inference, not something stated explicitly locally, so confirm with the Fountain County Health Department before building a separate greywater system. source
Rainwater harvesting
Generally allowedNo county ordinance or health department page addresses rainwater collection at all, and there's no indication of a prohibition, which lines up with Indiana's general lack of statewide restriction on rainwater harvesting.
Private wells & water rights
Generally allowedPrivate wells are permitted, with construction and driller licensing regulated at the state level by Indiana DNR's Division of Water, and the county's zoning rules require that new structures not be sited on top of an existing well. I couldn't confirm a separate Fountain County well-construction-permit page apart from the septic process, so it's worth asking the Health Department or DNR directly about your specific well plans. source
Living disconnected from utilities
Generally allowedLiving off municipal sewer and other utility hookups is allowed in Fountain County, but state law still requires any property not connected to city sewer to get a septic permit through the county Health Department, so you can go off-grid on electric and water but not skip an approved onsite sewage system. source
