Unincorporated Clarke County, Alabama has no building permit or countywide zoning: the county has no building, planning or zoning department, unlike the towns of Grove Hill, Jackson and Thomasville, which each have their own zoning ordinances and building codes inside their city limits123. Alabama counties are legally allowed to adopt building codes and zoning by ordinance, but Clarke County's own commission page shows no such department has been created45. Any new septic system still needs a permit from the Clarke County Health Department, which administers Alabama's onsite sewage program locally6.

Do you need a building permit in Clarke County, Alabama?
Unincorporated Clarke County has no building permit requirement: the county has no building, planning or zoning department at all1. Alabama law lets a county commission adopt building codes and permit programs by ordinance, so the absence here is Clarke County's own choice, not a state-imposed limit4. The towns of Grove Hill, Jackson and Thomasville are different: an official county hazard-mitigation plan states that all three have their own zoning ordinances, building codes and subdivision regulations, but those apply only inside each town's city limits, not to the rest of the county312. If you build your own one- or two-family home for your own use anywhere in Alabama, you are exempt from the state's home-builder license requirement as long as you act as your own contractor and do not sell within a year of completion9.
Who handles permits and septic questions in Clarke County?
Clarke County has no building, planning or zoning department -- the Clarke County Commission is the county's general administrative office for unincorporated land13. Reach the Commission at 251-275-3507, [email protected], P.O. Box 548, 114 Court Street, Grove Hill, AL 3645113. The Clarke County Health Department administers onsite sewage (septic) permits for the county as part of Alabama's statewide environmental health program1415. Reach the Health Department's environmental office at 251-275-4177, 22600 Highway 84 East, Grove Hill, Alabama 3645114.
Does Clarke County have zoning?
Clarke County itself has no zoning ordinance2. Alabama law does not give counties broad, general zoning authority outside a short list of special circumstances -- flood-prone areas and airport hazard areas among them -- and Clarke County has not created any local zoning authority of its own5. Because the county has no zoning authority, it sets no minimum dwelling size, minimum lot size, setback, lot-coverage or building-height rule for unincorporated land, and accessory dwelling units, tiny homes and manufactured homes are unrestricted by county zoning5. The towns inside the county are a different matter: Grove Hill, Jackson and Thomasville each have their own zoning ordinance that governs only land within that town's city limits, so a search for 'Clarke County zoning' can easily surface one town's rules instead of the unincorporated county's answer316.
How do septic permits work in Clarke County?
Any onsite sewage disposal system in Clarke County needs a Permit to Install from the Clarke County Health Department before construction begins, if the property is not connected to a public sewer7. The Health Department's Environmental Division handles soil and onsite sewage services as part of Alabama's statewide onsite sewage program, coordinated by the Alabama Department of Public Health15. The installer must be licensed by the Alabama Onsite Wastewater Board, and if soil percolation runs slower than 60 minutes or the site has a shallow limiting zone, only a registered engineer can design the system17. Only about 15.1% of Clarke County's soils are free of severe limitations for a conventional septic drain field, so budget for a site evaluation and likely a more involved system design18.
Can you live in an RV, tiny home or manufactured home on your land in Clarke County?
Tiny homes and manufactured homes are unrestricted by county zoning on private land in unincorporated Clarke County, since the county has no zoning authority to regulate them5. A manufactured home still has to meet Alabama's statewide definition -- built on a permanent chassis, at least 320 square feet once erected on site, connected to required plumbing, heating, air conditioning and electrical systems, and bearing a HUD seal -- and installed by a certified installer11. Long-term RV occupancy on private land is a different question: no official Clarke County source confirms or prohibits it, so this stays unconfirmed rather than assumed either way10. The City of Jackson runs its own Parkers Lake RV Park with hookups inside city limits, but that is a municipal park, not a rule for private land elsewhere in the county10.
Building on land in Clarke County: the steps, in order
- Confirm whether your parcel is inside Grove Hill, Jackson or Thomasville city limits; if so, that town's own zoning and building codes apply instead of the county's rules312.
- Outside city limits, no county building permit is required for the home itself, since Clarke County has no building or planning department113.
- Apply for a septic Permit to Install through the Clarke County Health Department before installing an onsite sewage system, unless you will connect to a public sewer147.
- If you build your own one- or two-family home for your own use, you are exempt from the state home-builder license as long as you act as your own contractor and do not sell within a year of completion9.
- If your driveway connects to an Alabama state highway, submit ALDOT Permit Form BM-111 to the District Administrator before you build the access19.
- If your parcel is in a mapped Special Flood Hazard Area and the community participates in the National Flood Insurance Program, expect to need a floodplain development permit from the local floodplain official before construction20.
What to check before you buy land in Clarke County
Clarke County averages 58.1 inches of rain a year and has spent only about 5.8% of years in severe drought, wetter and less drought-prone than most of the rural South2122. Only about 15.1% of the county's soils are free of severe limitations for a conventional septic drain field, even though 58.8% of the county's land sits at 15% slope or less, so gentle terrain here does not guarantee an easy septic site1823. About 90.4% of Clarke County is wooded, among the most forested counties in this index, useful context for clearing a building site and for timber value24. The county's effective property tax rate is about 0.3%, with a median property tax bill of just $388 a year, among the lowest in this index2526. Clarke County sits roughly 66 miles from the nearest metro area, with a population density of 18 people per square mile2728.
Watch-outs
- Long-term RV occupancy on private land in unincorporated Clarke County is unconfirmed -- no official county source addresses it, and the City of Jackson's own RV park is a separate municipal facility, not a countywide rule10.
- Grove Hill, Jackson and Thomasville each have their own zoning ordinance and building code that apply only inside that town's city limits -- do not assume a town's rule extends into unincorporated Clarke County312.
- Clarke County's own pages do not state whether building inspections, a certificate of occupancy, or a subdivision-approval process apply here -- ask the County Commission directly rather than assume either way13.
