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 rulesTrigg County, KY
Zoning & raw-land occupancy
Varies locallyTrigg County has no countywide zoning ordinance; outside Cadiz, land use is governed mainly by recorded subdivision deed restrictions rather than a zoning code. Inside Cadiz, the city has its own residential and commercial zoning districts administered with the Cadiz-Trigg County Planning Commission. source
Dwellings, tiny homes & RVs
Unclear - verifyNo Trigg County-specific rule on tiny homes, minimum dwelling size, or RV occupancy was found; the state's Kentucky Residential Code governs single/two-family dwellings but local enforcement outside Cadiz is not confirmed. Ask the county directly.
Building permits & codes
Varies locallyInside Cadiz, building permits come from City Hall; statewide, a state building permit and certified inspection (via KY DHBC) is required before any commercial construction, but single-family homes are generally exempt from that state fallback review, and Trigg County does not appear to run its own residential building permit program outside Cadiz. Confirm with the county Judge/Executive's office. source
Septic & composting toilets
Generally allowedThe Trigg County Health Department issues septic/plumbing permits and does site evaluations directly, rather than routing through the regional Pennyrile district office; a minimum lot size (about half an acre) applies for a septic system to be allowed per county planning materials. source
Greywater reuse
Unclear - verifyNo Trigg County ordinance or health department policy on greywater reuse was found; it defaults to the state framework under 902 KAR 10:085. Confirm local application with the Trigg County Health Department.
Rainwater harvesting
Generally allowedNo Trigg County ordinance restricting rainwater harvesting for non-potable use was found, so it appears to follow the generally permissive state baseline.
Private wells & water rights
Generally allowedNo Trigg County-specific well permitting scheme beyond the state's certified-driller requirement was found; the Trigg County Water District runs public water supply but does not appear to regulate private wells. source
Living disconnected from utilities
Varies locallyInside Cadiz, new construction must tap into water and sewer service per the city's process described in the county fact sheet; outside city limits, no forced-connection ordinance was found, but this is not confirmed either way. source
