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

Unincorporated Chambers County requires an approved proposed plat and a Permit to Develop before subdivision construction begins¹. The County Engineer issues the permit after County Commission approval¹. Plat review costs $100 per submission, or $500 if construction or road improvements are required; at final plat approval, such projects add $25 per lot and $0.75 per linear foot of road, and the developer also pays the county's inspection and testing charges¹.

The regulations exclude agricultural roads and buildings, immediate-family divisions, qualifying divisions into parcels larger than five acres and certain one-time two-parcel splits¹. Those exclusions do not waive septic, floodplain, environmental or municipal requirements¹. We could not confirm whether an ordinary home outside the subdivision process needs a county building permit, inspection or certificate of occupancy, so ask the County Engineer before starting work¹. Unlike most counties around it in Alabama, Chambers County requires a county building permit only in some cases¹. Alabama's residential-code framework changes in 2027, so ask which code will govern⁸.

The Chambers County Highway Department is the practical first call for subdivision development and access to county-maintained roads^1,9. The office is at 18017 US- 431, Lafayette, AL 36862, phone (334) 864-4359¹⁰. For a subdivision, submit the complete application package to the County Engineer at least 30 days before County Commission consideration; after Commission approval, the County Engineer issues the Permit to Develop¹. The Highway Department reviews proposed county-road access for safety and drainage and requires payment before county pipe installation is scheduled⁹. The Chambers County Health Department handles onsite-sewage applications and permits as part of the Alabama Department of Public Health's county-run program^3,11. The health office is at 5 North Medical Park Drive, Valley, Alabama 36854, phone 334-756-0758¹².

Unincorporated Chambers County appears to have no county zoning ordinance: a county plan names only the cities of Lafayette, Lanett and Valley as enforcing zoning controls, and describes unincorporated areas as subject to county subdivision regulations rather than general zoning^1,2. That plan dates from 2016, and we could not confirm whether a countywide zoning ordinance exists today, so ask the County Engineer². County subdivision regulations still govern qualifying divisions of land for sale, lease or building development¹. Subdivisions within county jurisdiction have a 30-foot minimum building setback from the right-of-way, while the Health Department determines minimum lot size from septic suitability¹. Lanett administers its own zoning ordinance, and Valley's zoning map covers only territory within Valley^13,14. Lafayette also zones². Inside a municipal planning commission's territory, the county's role is limited to required plat approval rather than enforcement¹.

We could not confirm any county rule on minimum dwelling size, building height or lot coverage outside subdivisions; ask the County Engineer, and ask the relevant city about its own zoning before relying on the unincorporated-land answer².

The Chambers County Health Department handles onsite-sewage applications and permits, under the Alabama Department of Public Health program that sets design, permitting, installation and use requirements^3,11. Before building a system, submit a Permit to Install application to the county health department; construction may begin only after the permit is issued, and the installer must be licensed by the Alabama Onsite Wastewater Board⁶. Homes and businesses not on public sewer need this permit, so an off-grid onsite system is allowed but never permit-free¹⁵. Only 44.6% of Chambers County soils lack severe limitations for a conventional drain field, so parcel-specific soil review matters⁷. Soil percolation over 60 minutes or a shallow limiting zone requires design by a registered professional engineer⁶. Call the health department to schedule inspection before covering the installation, and the system cannot be used until the department issues Approval for Use⁴. Inside Lanett, the city also requires its own written permit for private wastewater systems¹⁶. On county subdivision lots, the Health Department determines minimum lot size¹.

We could not confirm a county rule on living in an RV, a tiny home or a manufactured home on unincorporated Chambers County land, so ask the County Engineer about the parcel before moving anything onto it². A manufactured home used as a residence must meet Alabama's construction definition, carry a HUD seal and connect to required utilities¹⁷. Any dwelling not connected to public sewer still needs a Permit to Install before onsite sewage construction, inspection before the system is covered or used, and Approval for Use before the system operates^4,6. County-regulated subdivision lots remain subject to the 30-foot setback and a Health-Department-determined minimum lot size¹. Municipal zoning may apply inside Lafayette, Lanett or Valley, so verify the parcel's jurisdiction first².

1. Confirm whether the parcel is inside a municipality or a municipal planning commission's territory, because municipal rules may apply and the county's subdivision role can be limited to plat approval¹.
2. Ask the County Engineer whether an ordinary building permit or inspection is required; for a subdivision, submit the complete package at least 30 days before Commission consideration¹.
3. Obtain a Permit to Install from the Chambers County Health Department before septic construction begins^6,12.
4. If using Alabama's owner-builder licensing exemption, act as your own contractor, supervise the work yourself, build a one- or two-family home for your own occupancy, and do not offer it for sale; the exemption cannot be transferred, and a sale within 1 year of completion is presumptive evidence you built to sell⁵. Subcontractors handling more than $10,000 of work must be licensed¹⁸.
5. Obtain Highway Department approval for access to a county-maintained road^9,10.
6. Let the health department inspect the septic installation and obtain Approval for Use before using it⁴.

Confirm septic suitability because only 44.6% of county soils lack severe drain-field limitations and subdivision lot size depends on the Health Department's determination^1,7. Check the flood map and buildable area: land within a floodway cannot be platted for residential occupancy or building sites, and fill cannot raise land in the floodway¹. Verify legal access and obtain Highway Department approval before adding a connection to a county-maintained road⁹. If the seller is dividing land, confirm whether county subdivision review applies before closing; qualifying agricultural roads and buildings are excluded, but that exclusion does not erase other requirements¹. Chambers County is 78.9% wooded, so inspect clearing and road-building needs⁷. The effective property-tax rate is about 0.4%, and the median annual bill is about $496⁷.
