Barndominium builders in St. Clair County, Alabama
No building department listed on the county site, 2026-09-05. Confirm with the county
St. Clair County is the ridge-and-valley country east of Birmingham with two county seats, Ashville in the north and Pell City in the south, and Logan Martin Lake on the Coosa filling the southeast corner. Moody, Odenville, Springville, Argo and Margaret along the Interstate 59 corridor have absorbed most of the county's growth out of the Birmingham metro; the north around Ashville, Steele and Ragland is still farm and timber ground on the ridges. Sandstone ridges and limestone valleys alternate across the whole county.
Does St. Clair County require a building permit for a barndominium?
The county’s official department list, 17 departments long, has no building, planning, zoning or code enforcement department. The County Engineer holds the subdivision regulations and utility permits, and the Flood Management office holds the flood damage prevention ordinance and a development permit. Pell City, Moody, Springville and the other cities run their own building departments inside city limits.

Alabama leaves this decision to each county: state law authorizes a county commission to adopt building codes for its unincorporated areas, and no state office inspects a house. Inside city limits, the city's own building department applies whatever the county does.

Who issues the septic permit in St. Clair County?
The St. Clair County Health Department, after the soil is tested. The owner submits the state's Application for a Permit to Install an Onsite Sewage Disposal System to the county health department, and the installer must be licensed by the Alabama Onsite Wastewater Board. This applies on every lot in St. Clair County without public sewer, whatever the county's building permit status. The septic guide covers the process.

What is the ground like around Ashville and Pell City?
The county's official department list has no building, planning, zoning or code enforcement department. The County Engineer holds the subdivision regulations and utility permits, and a separate Flood Management office holds the flood damage prevention ordinance and its development permit. Pell City, Moody, Springville and the other cities run their own building departments.
What that changes is the septic evaluation, the foundation excavation and the pad. What it does not change is the process: the same soil evaluation and the same health department permit on every lot. The lot guide is the full checklist.
