Autauga County, Alabama requires a county development permit in or within 100 feet of a Special Flood Hazard Area, but the available county material does not establish a general residential building permit outside that area1. A county-road driveway needs access approval, and a new or repaired onsite sewage system needs a health-department permit23.

Do you need a building permit in Autauga County, Alabama?
Autauga County requires a development permit for property in or within 100 feet of a Special Flood Hazard Area1. In that area, development includes a new home or commercial structure, placement of a mobile home or RV, additions, remodeling, alterations, excavation, sheds and pole barns10. The county permit application has no fee, although an elevation certificate or no-rise certificate can create outside costs10. The available county material does not establish a general residential building permit outside the floodplain trigger, so call County Engineering before construction rather than treating silence as an exemption11. Starting January 1, 2027, residential builders must follow the applicable Alabama or local residential code12.
Who handles Autauga County building and development permits?
Autauga County Engineering handles the county approvals documented for rural development: floodplain development, subdivision review and access to county-maintained roads11132. Call the department at (334) 361-3761 before building near a Special Flood Hazard Area14. A driveway serving even one single-family residence must receive an access permit from the County Engineer when it connects to a county-maintained road; detailed engineering studies are generally unnecessary for that single residence unless the engineer identifies a safety or engineering concern2. If access is instead from an Alabama state highway, submit the state turnout form to the ALDOT District Administrator15.
Does Autauga County have zoning?
We could not confirm whether Autauga County has a countywide zoning ordinance; the available county material documents subdivision, floodplain and road-access controls but does not expressly answer the broader zoning question4. Alabama counties lack broad general land-use authority unless a narrower statute or local law supplies it16. For a specific unincorporated parcel, ask County Engineering about applicable county controls and ask the relevant municipality about land inside city limits. Regardless of zoning, Autauga County regulates subdivisions within its subdivision jurisdiction, and the County Engineer or designee reviews proposed plats before County Commission action13. Floodplain rules and county-road access approval can also constrain the building location102.
How do septic permits work in Autauga County?
The Autauga County Health Department's Environmental Office handles local septic applications while the Alabama Department of Public Health coordinates the statewide onsite sewage program5. A new onsite sewage system or repair requires a local health-department permit when the property is not connected to public sanitary sewer3. The application requires professional soil information, a legal description, plot plan and vicinity map, and it may require a construction plan; installation should not begin until the application and soil results are approved3. Only a registered engineer may design a system where soil percolation exceeds 60 minutes or a shallow limiting zone exists17. Only about 25.6% of county soils lack severe limitations for a conventional drain field, so make the site evaluation an early purchase contingency18.
Can you live in an RV, tiny home or manufactured home on your land in Autauga County?
Alabama allows a qualifying manufactured home to serve as a residence if it meets the state's definition, bears a HUD Seal, is installed by a certified installer and connects to the required utilities8. We could not confirm a countywide rule for living in an RV or tiny home on private land, so ask County Engineering about the parcel and any municipality with jurisdiction. An RV placed in or within 100 feet of a Special Flood Hazard Area counts as development and requires the county floodplain permit10. A manufactured home or tiny home using onsite sewage also needs health-department approval before installation or repair of the system3.
Building a home in Autauga County: the steps, in order
- Ask County Engineering whether the site is in or within 100 feet of a Special Flood Hazard Area and obtain the required development permit before work begins1.
- Obtain a County Engineer access permit for a driveway connecting to a county-maintained road, or use the ALDOT process for a state-highway entrance215.
- Send the Autauga County Health Department the soil information, legal description, plot plan, vicinity map and any required construction plan for onsite sewage review3.
- If acting as your own contractor on your own one- or two-family residence, follow Alabama's owner-builder conditions, including personally providing all material supervision7.
- If dividing land, submit the proposed plat for County Engineer review and County Commission approval before expecting county roads, utilities or services1319.
- Obtain inspection and approval for use of the onsite sewage system before occupancy20.
What to check before you buy land in Autauga County
Confirm flood status, legal road access and septic suitability before closing. Development in or within 100 feet of a Special Flood Hazard Area needs a county permit, and a connection to a county-maintained road needs County Engineer approval102. Only about 25.6% of county soils lack severe limits for a conventional drain field18. If the parcel is part of a proposed subdivision, county roads, utilities and services will not be extended until the subdivision regulations are met and final approval is granted19. Published subdivision charges include a $100 proposed-plat review fee, a $150 fee plus $10 per lot, site or unit, and $0.75 per linear foot of road to be constructed and inspected9. Private-well permitting for an ordinary individual well could not be confirmed; ask the health department about testing and the appropriate well authority.
Watch-outs
- The available material does not establish a general residential building permit outside the floodplain trigger, but county-road access, septic and subdivision approvals can still apply12313.
- Alabama requires an engineer-designed septic system where soil percolation is slower than 60 minutes or a shallow limiting zone exists, so do not assume a simple gravity system will pass without a percolation test17.
- Alabama's new statewide residential building code takes effect January 1, 2027 and could change what applies here if Autauga County has not adopted its own residential code by then; ask the county before you plan a build near that date12.
