Kentucky Tiny Home Zoning Laws
Kentucky has no statewide tiny house law, with regulations set entirely by individual counties and cities across its 120 counties.5 A recent bill nearly changed that dramatically — but it stalled, and knowing that matters if you're relying on outdated information.
A bill that almost changed everything, but didn't: House Bill 576, introduced in February 2025, proposed that at least one ADU be considered a permitted use in all residential zones statewide, without local permitting or review.2 This would have been a major breakthrough for ADUs in Kentucky. The bill stalled and currently remains inactive — it is not law. As of this writing, everyone still relies on county-level zoning ordinances and the Kentucky Residential Code, including Appendix Q, for guidance.2
1. A Genuinely Unusual Administrative Detail
In Breathitt County, located in eastern Kentucky's Appalachian Mountains, there is no dedicated planning and zoning department at all. Building permits are instead handled through the county judge-executive's office, with tiny houses on permanent foundations needing to meet basic dwelling safety standards.4 Enforcement here tends to be less structured than in more developed counties, simply due to limited administrative resources — not a specific tiny-home-friendly policy choice.4
2. County Examples
| County | Notable Detail |
|---|---|
| Jefferson County (Louisville) | Among the more progressive counties in Kentucky for ADU accommodation3 |
| Fayette County (Lexington) | Progressive ADU stance, with ongoing discussions potentially expanding provisions further3 |
| Kenton County | Recognizes tiny homes as single-family dwellings under Appendix Q, with designated zoning districts facilitating placement3 |
| Warren County | Follows Appendix Q with an emphasis on permanent foundations; THOWs limited to temporary use in RV parks3 |
| Daviess County | Supports tiny homes meeting IRC standards with mandatory building permits and permanent foundations for primary dwellings3 |
| Carter County | Rural Appalachian foothills and wooded valleys; predominantly rural with limited specific tiny house regulations4 |
3. Rural vs. Urban Divide
Rural areas in Kentucky are generally more flexible, with fewer zoning restrictions and larger lot sizes, while urban centers like Louisville and Lexington tend to impose stricter zoning requirements, including minimum square footage rules or designated tiny-home zones.1 This split is more pronounced in Kentucky's Appalachian counties specifically, where limited administrative capacity can mean less consistent enforcement either way.
4. Homes on Wheels
THOWs are classified as recreational vehicles and are typically allowed only in RV parks or designated areas, rarely permitted for permanent residential use — though some rural counties, particularly ones with limited zoning infrastructure, may be more lenient in practice.1
How to Verify Your Specific Situation
- Don't rely on outdated information suggesting HB 576 passed — confirm its current legislative status before assuming a statewide ADU right exists.
- In Appalachian counties with limited administrative capacity, confirm who actually handles permitting — it may be the judge-executive's office rather than a planning department.
- If in Louisville or Lexington, research current ADU ordinance specifics directly, since both are actively evolving their policies.
- Confirm current Appendix Q adoption status for your specific county before assuming statewide uniformity.
