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

A single home on an existing lot in unincorporated DeKalb County does not appear to need a county building permit: the county's Permit to Develop covers subdivision development, not ordinary construction on one lot¹. The county subdivision regulations apply to all unincorporated land in DeKalb County¹. Other approvals still apply: septic, utility work in a county right-of-way, floodplain development and state-highway access^6,8,10,11. Inside Fort Payne, construction requires a city permit before work begins³. An owner-builder exemption covers home-builder licensing, not any permit that otherwise applies⁷. We could not confirm a certificate-of-occupancy requirement, so give Engineering the parcel location and scope of work and ask which approvals apply⁸.

The county lists no general building department, so begin with the DeKalb County Engineering Office for an unincorporated parcel⁸. Engineering enforces the county subdivision regulations and issues permits for utilities installed in county road rights-of-way⁸. A subdivision developer files a proposed plat and Permit to Develop application at least 30 days before consideration¹. Published subdivision fees are $350 plus $35 per lot for a minor subdivision, or $700 plus $70 per lot and $0.35 per linear foot of new road for a major subdivision¹. Inside Fort Payne, the city's Inspections and Zoning Department handles construction permits instead³. The Road Department handles maintenance reports, not construction permits¹². For mapped flood-hazard land, ask Engineering or the Commission who the local floodplain official is^11,13.

We could not confirm a countywide zoning ordinance for unincorporated DeKalb County, Alabama⁵, and Alabama counties do not have broad land-use authority under general state law². County subdivision regulations still govern land divisions in unincorporated areas, and stricter municipal requirements control where a municipality exercises extraterritorial planning authority¹. Those regulations include minimum lot-size standards for new lots, but we have no numeric schedule and no countywide minimum for an existing lot¹. Fort Payne maintains its own zoning ordinances inside the city³; the City Clerk's official map controls current zoning status¹⁴. For unincorporated land, we could not confirm general rules for setbacks, minimum dwelling size, RV occupancy or tiny-home occupancy⁵. Ask Engineering which subdivision controls affect the parcel⁸.

Septic permits stay with the county health department, not the city: the DeKalb County Health Department's Environmental Office handles onsite sewage applications and permits⁴, as part of Alabama's statewide program run through county health departments¹⁵. State law requires a permit for any new onsite system or repair when a property is not connected to public sewer¹⁶. Submit an Application for a Permit to Install before constructing the system, and wait for approval⁶. The system must go where the soil tests were performed and meet required separation distances from wells, surface waters and easements⁶. Only about 6.5% of DeKalb County soils rate free of limitations for a conventional drain field, so a site evaluation can change the buildable area and cost¹⁷. Health Department approval does not replace planning or zoning approval⁶. Call the Environmental Office before fixing the house location⁹.

Long-term RV and tiny-home occupancy on private land in unincorporated DeKalb County remain unconfirmed⁵. Alabama treats a park model as temporary quarters for recreational, camping, travel or seasonal use, and that rule does not authorize permanent occupancy of an ordinary RV outside an RV park¹⁸. A qualifying manufactured home can be used as a residence under state standards, but that does not settle siting, septic or local approval¹⁹. Before living in an RV during construction or placing a tiny or manufactured home, ask Engineering about subdivision constraints and the Health Department how sewage disposal must be approved^6,8. The lack of a confirmed countywide rule is not permission for a particular use⁵.

1. Confirm whether the parcel is unincorporated or inside Fort Payne or another municipality; Fort Payne requires city construction permits³.
2. Ask DeKalb County Engineering what approvals apply to an unincorporated lot; the county's Permit to Develop covers subdivisions^1,8.
3. If no city or central sewer serves the site, obtain the Health Department's Permit to Install before construction and keep the house within the tested area⁶.
4. If the project divides land, start the subdivision process first; agricultural roads and buildings are exempt from the county regulations, but not from septic or other requirements¹.
5. Apply to ALDOT for an access permit if the driveway connects to a state highway¹⁰.
6. Check the flood map and identify the local floodplain official before work in a mapped hazard area¹¹.
7. Hire a licensed builder, or confirm every condition of the owner-builder licensing exemption is met⁷.

Start with septic: only about 6.5% of DeKalb County soils rate free of limitations for a conventional drain field, so get a site evaluation before committing to a house location^6,17. Confirm that every lot has legal road frontage; subdivision lots must connect to an existing maintained road or an approved proposed public road¹. A driveway onto a state highway needs an ALDOT access permit¹⁰. If the tract was recently divided, verify final subdivision approval, because the county does not accept roads or extend utilities and services to a subdivision until the regulations are met and final approval is given¹. Check flood status and the local floodplain official¹¹. Before closing, ask Engineering about subdivision status, setbacks, RV use and tiny homes, since those countywide rules are unconfirmed^5,8.
