Do you need a building permit in Franklin County, Alabama?
Unincorporated Franklin County, Alabama appears to have no general county building-permit requirement1. Franklin County requires a Floodplain Development Permit before buildings, grading, filling, excavation, or other development begins in a Special Flood Hazard Area or another county-designated floodplain2. Alabama’s Division of Construction Management does not regulate ordinary residential property; its State Building Code jurisdiction is limited to specified project categories, not every rural home16. Beginning January 1, 2027, residential home builders must follow the applicable state or local residential building code17. We could not confirm a separate county residential code or ordinary inspection program; ask the Franklin County Commission1. Alabama’s owner-builder licensing exemption requires the owner to act as contractor and personally provide all material supervision for a home intended for the owner’s use, not sale; hiring a paid supervisor defeats the exemption11. The exemption does not waive separate construction approvals, and subcontractors must be licensed when their undertaking exceeds $10,00011.
Who issues building permits in Franklin County, and how do you reach them?
For ordinary building-permit questions on unincorporated land, start with the Franklin County Commission at 410 Jackson Avenue North, Russellville, AL 35653, phone (256) 332-885018. The Commission can direct you to the Floodplain Administrator and county forms; a Floodplain Development Permit is required before work begins in a Special Flood Hazard Area or an additional county-designated flood area19. Inside Russellville, the city issues building permits for most construction and inspects new construction and many remodeling projects in phases320. City building-permit authority does not move septic permitting: the Franklin County Health Department handles onsite-sewage applications and permits throughout the county921. The County Engineer handles county-road and subdivision questions at (256) 332-843422.
Does Franklin County have zoning?
Unincorporated Franklin County has no county zoning ordinance; no county zoning rule sets dwelling size, lot size, setbacks, lot coverage, building height, accessory dwellings, or RV and tiny-home occupancy there5. Russellville has its own zoning for structures and uses within city limits; ask the city’s Building, Licensing, and Zoning Department for parcel-specific district rules423. Septic permitting remains with the Franklin County Health Department throughout the county67. Subdivision control is separate: Franklin County regulates land divisions outside municipal limits and municipal planning commissions’ territorial jurisdiction, with limited county plat approval also possible in municipal planning areas unless waived24. Agricultural roads or buildings on private agricultural property are excluded from county subdivision regulation; that exclusion does not waive other applicable approvals13.
How do septic permits work in Franklin County?
The Franklin County Health Department handles onsite-sewage applications and septic permits through its Environmental Office at 801 Highway 48, Russellville, AL 35654, phone 256-332-27009217. Before construction, submit an Application for a Permit to Install; construction may begin only after the Health Department issues the Permit to Install25. The application includes professional soil information, a legal description, plot plan, vicinity map, and sometimes a construction plan26. Only 3.5% of Franklin County soils are rated without severe limitations for a conventional drain field, so evaluate the site before choosing a house location or purchase price15. The Health Department must have an opportunity to inspect before the installation is covered, subject to the state's inspection-delay exception, and the system cannot be used until Approval for Use is issued27. The installer must hold an Alabama Onsite Wastewater Board license25.
Can you live in an RV or tiny home on your land in Franklin County?
For an RV or tiny home on unincorporated Franklin County land, sanitation and floodplain rules still apply: an onsite system must go through the Health Department when public sewer is unavailable or impractical, and regulated floodplain development needs a county permit1028. Alabama recognizes a manufactured or mobile home as a residence when it meets the state's definition, bears a HUD Seal, connects to required utilities, and is installed by a certified installer29. A manufactured home cannot be skirted until the state commission inspects the setup; if no inspection occurs within 10 days after notice, skirting may proceed12. Alabama park models are temporary living quarters, not permanent dwellings30. We could not confirm a general certificate-of-occupancy rule for an ordinary unincorporated home, so ask the County Commission before planning move-in1.
Building a home in Franklin County: the steps, in order
- Confirm whether the parcel is inside a municipality or on unincorporated land; Russellville has city building permits, inspections, and zoning, while septic permits remain with the county Health Department32049.
- Ask the County Commission whether the parcel is in a regulated floodplain and obtain the Floodplain Development Permit before grading, filling, or construction when required2.
- If the project divides land, submit the proposed plat to the County Engineer at least 30 days before Commission consideration; covered building development must wait until the final plat is recorded24.
- Evaluate the septic site early because only 3.5% of county soils are rated without severe conventional-drain-field limitations15.
- Apply to the Health Department for the septic Permit to Install and leave the system uncovered for the department's inspection opportunity2527.
- For a state-highway driveway permit, submit form BM-111 to the ALDOT District Administrator; ask the County Highway Department about county-road access3122.
- If acting as owner-builder, personally provide all material supervision and keep separate floodplain and septic approvals in place11.
What to check before you buy land in Franklin County
Start with septic feasibility: only 3.5% of Franklin County soils are rated without severe limitations for a conventional drain field, so get a site evaluation before committing to a house site15. Confirm municipal boundaries because Russellville has city zoning and building permits, while other municipal zoning rules vary438. Check the flood map because development in a Special Flood Hazard Area or another county-designated floodplain requires a Floodplain Development Permit2. If the sale creates new lots, ask the County Engineer about subdivision approval and fees: the published schedule lists a $25 Permit to Develop, minor-subdivision review at $500 plus $25 per lot/site, and major-subdivision review at $500 plus $50 per lot/site and $0.25 per linear foot of new road32. Inspection and testing charges are additional; ask the County Engineer which county review applies if the parcel falls within a municipal planning commission’s jurisdiction33. Subdivision lots need road access with a deeded travel way at least 30 feet wide, and arterial access may be limited3435.
Watch-outs
- Franklin County's no-zoning answer applies to unincorporated land; Russellville has city zoning and building permits, and other municipal rules must be checked separately583.
- A land division can trigger county subdivision review, published subdivision fees, and access standards even though unincorporated Franklin County has no zoning ordinance363734.
- No official Franklin County source confirms whether a certificate of occupancy or a general building inspection is required for an ordinary home outside a flood zone; confirm directly with the County Commission office1.
