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 rulesShelby County, KY
Zoning & raw-land occupancy
RestrictedShelby County has adopted countywide zoning administered through the Triple S Planning Commission (with Shelbyville and Simpsonville), covering unincorporated county land and city land. A zoning permit is required before building. source
Dwellings, tiny homes & RVs
Unclear - verifyNo county-level rule specific to tiny homes or long-term RV residency was confirmed; a physical address and zoning approval are required before any building or electric permit, per the county building permit process. source
Building permits & codes
RestrictedShelby County and the City of Shelbyville each maintain their own building inspector and require a defined permit sequence: septic permit, zoning permit, then building permit, with house plans submitted. source
Septic & composting toilets
Generally allowedOn-site sewage systems are permitted through the Shelby County Health Department or North Central District Health Department, which inspects systems under the state's on-site sewage regulations; composting toilets are not separately addressed and likely fall under the same review, not confirmed. source
Greywater reuse
Unclear - verifyNo Shelby County-specific greywater ordinance was found; this likely inherits the state on-site sewage rule administered by the same local health department, but that is not confirmed for greywater specifically. Ask the health department directly.
Rainwater harvesting
Unclear - verifyNo Shelby County ordinance addressing rainwater harvesting was found; it likely falls under the state baseline (non-potable use generally allowed, potable connections trigger state plumbing code), but this is not confirmed locally.
Private wells & water rights
Generally allowedPrivate wells are legal and don't require a separate county permit, but drilling must be done by a Kentucky Certified Well Driller under state law; geology in much of the county's upland areas limits well yield for dependable domestic supply. source
Living disconnected from utilities
Unclear - verifyNo explicit Shelby County ordinance requiring connection to public water, sewer, or grid power was found, but the building permit process functionally requires an approved septic or sewer connection first; whether unpermitted off-grid living draws separate zoning enforcement is not confirmed.
