37.3238, -84.9223 · 810 ft elevationRead this before you act on anything below. This is my researched starting point for Casey County, KY, 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 rulesCasey County, KY
Zoning & raw-land occupancy
Unclear - verifyI couldn't find an official Casey County Fiscal Court zoning ordinance online. Kentucky counties aren't required to have zoning under KRS Chapter 100, and it looks like Casey County may not, but there's a regional planning/zoning contact listed in Liberty, KY worth calling to confirm, especially if your land is inside or near city limits. The City of Liberty may run its own separate zoning through a city planning commission. source
Dwellings, tiny homes & RVs
Unclear - verifyThere's no Casey County-specific document I found on tiny homes or RV standards, so this falls back to the Kentucky state baseline, which only requires building permits/inspections where a local government has opted into enforcement under KRS 198B.060. The Lake Cumberland District Health Department's septic process does treat RVs and mobile homes differently (no temporary sewage permit for them), which suggests they're recognized as a separate category locally, but I'd confirm directly with the county or LCDHD.
Building permits & codes
Unclear - verifyI couldn't confirm whether Casey County (outside the City of Liberty) has adopted local building-permit enforcement at all; state law under KRS 198B.060 makes this optional for each locality, and no official county building department page turned up. What is documented is that Lake Cumberland District Health Department ties permanent electric hookup approval to septic/site-evaluation sign-off, so ask both the county and LCDHD before you build. source
Septic & composting toilets
Generally allowedSeptic systems are permitted and administered by the Lake Cumberland District Health Department under state regulation, following the standard statewide process: a site evaluation and soil test pits come first, then a certified installer applies for the actual septic permit. Composting toilets aren't separately addressed on LCDHD's pages, so I'd assume the same site-evaluation framework applies until you confirm otherwise with LCDHD. source
Greywater reuse
Generally allowedGreywater reuse is permitted under the separate Kentucky state greywater regulation, and I didn't find any Casey County or LCDHD page specifically addressing standalone greywater systems. There are unconfirmed, non-official reports that the local environmental permitting officer wants detailed engineering plans for alternative systems, so it's worth asking LCDHD directly before you build one.
Rainwater harvesting
Generally allowedRainwater harvesting is permitted; I found no Casey County or LCDHD restriction on it, and no state-level permit scheme limiting non-potable rainwater use, so the state baseline of allowing it stands.
Private wells & water rights
Generally allowedPrivate wells are permitted in Casey County, but construction must be done by a Kentucky Certified Water Well Driller under state law. Locally, LCDHD's process shows the plumbing inspector issuing the water permit only after the septic permit is released, so expect that sequencing if you're building a new home.
Living disconnected from utilities
Unclear - verifyI found no explicit Casey County ordinance that requires you to hook up to grid power or municipal utilities. That said, LCDHD's own new-home process shows permanent electric hookup is conditioned on completing the septic/site-evaluation step first, mirroring a pattern seen at other Kentucky health departments. Whether a non-residential structure (like a barn) could sidestep this chain is only discussed in unofficial forums, not confirmed by any official source, so check directly with LCDHD and the county. source
