Building permits, zoning and land rules in Marengo County, Alabama

#3 of 67 in Alabama

Unincorporated Marengo County, Alabama has no building-permit or zoning department: the county's own site lists only the Sheriff, E-911 and the Economic Development Authority under its "other departments," and rural Alabama counties generally don't require a building permit in unincorporated areas12. Because the county has no zoning ordinance, it sets no county rule on RVs, tiny homes, manufactured homes, accessory dwellings, minimum lot size, setbacks or building height3. Septic systems still need a Permit to Install from the Marengo County Health Department before construction, and Alabama's owner-builder exemption lets you act as your own contractor if you supervise the work personally45.

Do you need a building permit in Marengo County, Alabama?

No, not in unincorporated areas. Marengo County's official site lists no building-permit or inspection department; only the Sheriff, E-911 and the Economic Development Authority appear under "other departments," and rural Alabama counties generally don't require a building permit outside their cities1. That's a county-census finding drawn from the county's own department listing rather than a quoted ordinance, so confirm with the Marengo County Commission before you build if you want certainty10. Alabama's owner-builder exemption is a licensing exemption, not a county-permit rule by itself: it lets an owner who acts as their own contractor and personally supervises the work skip Home Builders Licensure Board licensing, as long as any subcontractor's portion over $10,000 is licensed11. Starting January 1, 2027, Alabama's statewide Residential Building Code becomes mandatory for licensed home builders unless Marengo County or your city has adopted its own residential code by then, so check back with the commission closer to that date12.

Who do you call about county permits and land questions in Marengo County?

Marengo County has no building or planning department, so the County Commission is the practical first call for anything not covered below10. Reach the Commission at (334) 295-2200, 101 E. Coats Ave., Linden, AL 3674810. Septic permits go through the Marengo County Health Department instead, at 334-295-4205, 303 Industrial Drive, Linden, Alabama 367484.

Does Marengo County have zoning?

No. Marengo County's site lists no planning or zoning office, and Alabama counties generally lack broad land-use regulatory authority unless the legislature grants it by local law, which it has not done for Marengo County213. Because the county has no zoning ordinance, it sets no county rule on minimum dwelling size, minimum lot size, setbacks, lot coverage or building height, and it does not restrict accessory dwellings, RVs, tiny homes, manufactured homes or temporary camping on unincorporated land3. This is a county-level answer only: any incorporated city inside Marengo County can adopt its own zoning within its own limits, so check separately if your parcel is inside a city.

How do septic permits work in Marengo County?

Alabama law requires anyone not connected to a public sanitary sewer to get a Permit to Install from the local health department before building or repairing an onsite sewage system, and in Marengo County that's the Marengo County Health Department64. Construction can't start until that permit is issued, and if your soil's percolation rate is slower than 60 minutes, or a shallow limiting zone is present, only a registered engineer can design the system6. Plan on that extra step: only about 5.6% of Marengo County's soils are rated without severe limits for a conventional septic drain field, among the toughest odds in this guide series, so budget for a site evaluation and likely an engineered or alternative system7. Call the Health Department before you commit to a parcel that doesn't already have a working system4.

Can you live in an RV or tiny home on your land in Marengo County?

Yes. Marengo County has no zoning ordinance, and Alabama law does not grant the county general land-use authority, so the county itself does not restrict RV, tiny-home, manufactured-home or accessory-dwelling occupancy on unincorporated land3. A manufactured home still has to meet Alabama's statewide rules to be occupied: it must be built on a permanent chassis, carry a HUD Seal, be installed by a certified installer, and be connected to required plumbing, heating, air-conditioning and electrical systems14. This is a county-level answer only; if your land is inside an incorporated city in Marengo County, its own zoning rules would apply instead.

Building a home in Marengo County: the steps, in order

  1. Confirm the parcel is unincorporated, since this guide's answers don't apply inside any of the county's cities.
  2. Apply for a septic Permit to Install with the Marengo County Health Department before any construction, and budget time for a site evaluation given the county's soils47.
  3. If you're acting as your own contractor under the owner-builder exemption, supervise the work personally and use licensed subcontractors for any portion over $10,00011.
  4. If your driveway connects to a state highway, apply to ALDOT for a turnout permit (Form BM-111) before construction9.
  5. If your project disturbs an acre or more of land, check whether you need ADEM construction stormwater permit coverage, which carries a $1,385 application fee15.
  6. If you'll farm, ranch or run timber on 5 or more acres, apply for the county's current-use property-tax exemption by December 31 to have it apply the next tax year8.
  7. Call the County Commission to confirm nothing has changed since this guide was written, especially on zoning, floodplain or building-permit questions10.

What to check before you buy land in Marengo County

Soils and septic: with only about 5.6% of Marengo County's soils free of severe limits for a conventional drain field, get a site evaluation from the Health Department before you count on a basic system74. Access: a driveway onto a state highway needs an ALDOT turnout permit9. Taxes: Marengo County's effective property tax rate runs about 0.4%, with a median annual bill near $397, among the lowest in this guide series, and a 5-acre-plus agricultural current-use exemption can lower it further16178. Land and homes: farmland averages about $2,247 an acre and a typical home is valued around $134,5391819. Community and distance: the county sits about 67 miles from the nearest metro area, with roughly 19.1 people per square mile and about 18,684 residents countywide, and it's heavily wooded at about 75.5% forest cover20212223. Climate: Marengo County averages about 54.1 inches of rain a year with severe drought in only about 3.5% of years, a wet, drought-resistant profile2425.

Watch-outs

  • The county's no-building-permit, no-zoning answer comes from its department directory, not a signed county letter; call the Marengo County Commission at (334) 295-2200 to confirm before you build110.
  • Alabama's statewide Residential Building Code becomes mandatory for licensed home builders on January 1, 2027, unless Marengo County or your city has adopted its own residential code by then12.
  • No confirmed county floodplain-permit contact was found for Marengo County; if your parcel is in a mapped flood zone, ask the County Commission who administers development permits there before you build10.
