Building permits, zoning and septic rules in Crittenden County, Kentucky

Yes. Crittenden County requires a building permit before regulated construction, alteration, repair, relocation or occupancy changes, as well as permits for regulated electrical, gas, mechanical or plumbing-system work¹. The local single-family inspection program applies outside the City of Marion². The Kentucky Residential Code applies statewide to single-family residential construction¹⁴. Some small accessory structures, fences, retaining walls, tanks, driveways and sidewalks qualify for code exemptions, so describe the full project to the Local Building Inspector before starting work¹. The building official receives applications, reviews plans, issues building permits and inspects permitted work¹. The fiscal court sets county building-permit fees, which must be reasonable and cannot exceed the cost of the service¹⁵. We could not confirm Crittenden County's current fee schedule, application form or inspection sequence, so request them from the Local Building Inspector.

Crittenden County has a designated Local Building Inspector; call 270-619-0813 or email fwallace01@icloud.com about building permits, plan review and inspections outside the City of Marion². The county program expressly excludes Marion, so ask the city which office issues a building permit there². The local inspector handles single-family inspections where the county program applies, while other building types may fall under a different local or state program^2,14. The building official receives applications, reviews construction documents, issues building permits and checks permitted work for compliance¹. Septic authority does not shift to Marion: the Crittenden County Health Department handles onsite sewage site evaluations, septic permits and inspections throughout Crittenden County^5,16. For county-road access, contact the Crittenden County Road Department at 270-965-0892; we could not confirm a county driveway-permit rule¹⁷.

The City of Marion has zoning administered by its Planning & Development Commission³. No countywide zoning is reported for unincorporated Crittenden County, but official county material did not confirm the limits of zoning coverage outside Marion⁴. Ask the County Judge Executive's office about the parcel before treating minimum dwelling size, minimum lot size, setbacks, lot coverage or building height as unrestricted. Marion buyers should take zoning questions to the city, while septic site evaluations, permits and inspections remain with the Crittenden County Health Department^3,16. Land division is separate: subdivision within a planning-unit jurisdiction requires commission approval, and the plat must be approved before the county clerk records it¹⁸. Kentucky excludes a division for agricultural use that creates no new street from the statutory definition of a subdivision¹³. Confirm that a proposed split and future residential use fit the exception before relying on it.

Kentucky administers onsite sewage through local health departments, and the Crittenden County Health Department in the Pennyrile District is the local contact^5,16. The department evaluates site and soil conditions, and a permit to construct, install or alter the onsite system must be obtained before any part of that work begins⁶. For a new home or business using subsurface discharge, the department may issue a permit only after finding the property suitable⁷. A certified installer must submit a drawing with grade shots before the permit can issue; a homeowner doing the installation needs a homeowner's permit from the local health department^6,7. Every installed, altered or repaired onsite system requires inspection by a certified inspector⁶. Only 5% of Crittenden County soils are rated “not limited” for a conventional drain field; that does not make septic impossible, but supports making the site evaluation an early purchase contingency¹⁰.

We could not confirm a Crittenden County rule expressly allowing or prohibiting long-term RV or tiny-home occupancy on private land. The reported absence of countywide zoning in unincorporated Crittenden County does not by itself authorize residential occupancy in an RV or tiny home, and Marion has its own city zoning^3,4. Outside Marion, ask the Local Building Inspector how a tiny home, manufactured home or utility connection will be classified; inside Marion, also ask the city about zoning approval^2,3. A utility may not connect service to a permitted, code-regulated building or system until the building official and applicable licensed or certified people release it¹. Off-grid living does not remove septic requirements: where sewer is unavailable, the residence needs an approved private sewage system after site evaluation and a septic permit from the local health department¹⁹.

1. For a tract split within a planning-unit jurisdiction, confirm commission approval and an approved plat before recording¹⁸.
2. Ask Marion about city zoning approval if the parcel is inside the city; for land outside Marion, ask the County Judge Executive's office to confirm parcel-specific land-use limits^3,4.
3. Have the Crittenden County Health Department evaluate the site; a septic permit depends on a suitable result⁷.
4. Outside Marion, submit construction documents and apply for the building permit through the Local Building Inspector; inside Marion, ask the city which office issues the building permit^1,2.
5. A homeowner personally doing plumbing must apply before work, file an affidavit and follow the state plumbing code; this is not an exemption from building, septic, electrical, HVAC or zoning requirements⁸.
6. Apply to the Kentucky Department of Highways District Engineer before building a new farm or single-family driveway onto state right-of-way¹¹.
7. Arrange building and septic inspections, then obtain applicable utility releases and occupancy approval before moving in^1,6.

Make septic feasibility a purchase contingency: only 5% of Crittenden County soils are rated “not limited” for a conventional drain field, and the Health Department must find a subsurface-system site suitable before issuing the septic permit^7,10. Kentucky requires a state floodplain permit before construction, demolition or renovation within a floodplain²⁰. Development in, along or across a stream—including a house, crossing, fill, excavation or grading—requires a Kentucky Division of Water floodplain permit; general permits exclude new structures, so a new house requires an individual permit²¹. NFIP-participating communities also require local floodplain permits; we could not confirm the local administrator for unincorporated Crittenden County, so ask the County Judge Executive’s office²¹. For a tract split within a planning-unit jurisdiction, confirm commission approval and plat recording before closing¹⁸. Confirm building-permit scope with the Local Building Inspector outside Marion; inside Marion, ask the city about building-permit authority and zoning approval^1,2,3. Ask the Road Department about county-road access, or apply to the state District Engineer for a new farm or single-family approach onto state right-of-way^11,17.
