Tippecanoe County, IN
40.3659, -86.8575Read this before you act on anything below. This is my researched starting point for Tippecanoe 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 rulesTippecanoe County, IN
Zoning & raw-land occupancy
RestrictedThe Area Plan Commission administers a countywide Unified Zoning Ordinance covering unincorporated Tippecanoe County plus Lafayette, West Lafayette, Battle Ground, Clarks Hill, and Dayton. Raw land is not unregulated here. source
Dwellings, tiny homes & RVs
RestrictedADUs are capped (one per property, detached ADUs limited in size) per the APC's FAQ, and any structure over a modest size needs a building permit. Full-time RV or tiny-house-on-wheels living outside a campground is not confirmed by official sources; ask the Building Commission. source
Building permits & codes
RestrictedThe county Building Commission issues permits for unincorporated areas, checking zoning compliance first; Lafayette and West Lafayette run separate city permit offices. source
Septic & composting toilets
Generally allowedThe county Health Department's Environmental Division permits and inspects septic systems, applying the state's 410 IAC 6-8.1 rule which the county has adopted by reference. source
Greywater reuse
Unclear - verifyNo dedicated county greywater ordinance or page was found; the county's sewage ordinance incorporates the state rule generally, so greywater likely gets treated as sewage. Confirm with the Health Department's Environmental Division.
Rainwater harvesting
Generally allowedNo county ordinance restricting rainwater harvesting was found; this appears to follow the unregulated state baseline, but it's not formally confirmed by a county page.
Private wells & water rights
Generally allowedPrivate wells fall under Indiana DNR's statewide well-record and water-rights program; no separate county well-permitting office was identified. source
Living disconnected from utilities
Generally allowedNo countywide ordinance mandating hookup to public water, sewer, or electric was found; a special Regional Sewer District exists only for the Tippecanoe and Chapman Lakes area, not countywide.
