Off-Grid Living in Tippecanoe County, Indiana

Tippecanoe County surprised me a bit when I dug into it, because unlike a lot of rural Indiana counties, it actually has countywide zoning. The Area Plan Commission (APC) of Tippecanoe County runs a Unified Zoning Ordinance (UZO) that covers unincorporated land as well as Lafayette, West Lafayette, Battle Ground, Clarks Hill, and Dayton. So if you're picturing "buy some acreage and do whatever," that's not how it works here. Zoning applies everywhere, and the APC investigates violations even out in the unincorporated county.

Building permits are split by jurisdiction. If you're in unincorporated Tippecanoe County, the county Building Commission issues permits for construction, demolition, and electrical work, and requires zoning sign-off before a permit is granted. Inside Lafayette or West Lafayette, you'd go through those cities' own permit offices instead.

On dwellings, tiny homes, and ADUs: the county's ADU rules are fairly specific, capping detached ADUs at a defined square footage and allowing only one per property, per the APC's FAQ. Any structure over a modest square footage threshold needs a building permit. Whether you could legally live full-time in an RV or tiny house on wheels outside a campground setting isn't something I found spelled out in official sources, so I'd call that unclear and worth confirming directly with the Building Commission.

Septic is required for any off-sewer dwelling, and it's administered locally by the Tippecanoe County Health Department's Environmental Division, which issues permits and inspects new and repaired systems. The county's sewage ordinance adopts Indiana's state onsite sewage rule (410 IAC 6-8.1, referenced in the county code) by reference, so state technical standards apply here too. Composting toilets as a standalone legal replacement for septic aren't addressed anywhere I could find, so that's another one to confirm with Environmental Health directly.

Greywater and rainwater harvesting don't have dedicated county pages or ordinances that I found. My best read is that the state's general sewage framework would apply to greywater (meaning it's treated as sewage rather than getting a special exemption), while rainwater collection appears to be permitted with no county-specific restriction identified, though I'd call both "not confirmed" as a formal county position.

Wells fall under Indiana DNR's statewide well-record and water-rights program. No county-level well permitting office beyond the state process turned up in my research. And on the bigger question of living entirely off public utilities, I couldn't locate any countywide mandatory-hookup ordinance forcing you onto water, sewer, or electric, aside from a special Regional Sewer District that covers Tippecanoe and Chapman Lakes specifically, not the whole county.

Bottom line: Tippecanoe County is zoned and permitted more tightly than "no rules" rural counties, so plan on dealing with the APC and Building Commission early rather than after the fact.
