Read this before you act on anything below. This is my researched starting point for Grant 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 rulesGrant County, IN

Zoning & raw-land occupancy
RestrictedGrant County has had countywide zoning since 1974, administered by the Area Plan Commission, with a Board of Zoning Appeals for variances and special exceptions under state law. source
Dwellings, tiny homes & RVs
Unclear - verifyThe county enforces the IRC with Indiana amendments for construction, but no official Grant County page confirms minimum dwelling size or a specific policy on tiny homes or RVs as permanent residences. Not confirmed, call the Area Plan Department. source
Building permits & codes
RestrictedThe Grant County Area Plan Department issues improvement location and building permits, requires accessory building permits above a certain size, and issues a Certificate of Occupancy at completion. source
Septic & composting toilets
Generally allowedState administrative code requires a septic tank and soil absorption system for homes not on sewer or using a sanitary privy, and the Grant County Health Department issues the required septic permit through a soil scientist and licensed installer. source
Greywater reuse
Unclear - verifyNo Grant County page addresses greywater specifically. It's presumably folded into the septic requirement since state code treats non-privy wastewater that way, but this is not confirmed locally.
Rainwater harvesting
Generally allowedNo Grant County ordinance or health page restricts rainwater collection, consistent with Indiana's general lack of a state prohibition.
Private wells & water rights
Varies locallyIndiana requires well drillers to be licensed by the DNR statewide, but whether Grant County's Health Department separately requires a well-construction permit beyond that is not confirmed, ask the Environmental Division. source
Living disconnected from utilities
Generally allowedIndiana state law does not mandate utility hookup, and no Grant County ordinance requiring mandatory connection was found, though individual towns within the county may have their own municipal rules.
