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

Cullman County requires a floodplain development permit before residential construction, manufactured-home placement, fill, excavation or other covered development in regulated flood-hazard areas of the unincorporated county¹. The floodplain requirement does not establish a general home-building permit outside those areas; the ordinance requires the application to go to the Cullman County Engineer before any development begins, so ask about the exact parcel and project¹¹. Cullman County does not inspect structures for plumbing, electrical or structural integrity and does not issue or require a certificate of occupancy⁸. Those statements do not establish whether the county has adopted a residential building code; confirm code requirements with the County Commission before designing a home.

The Cullman County Road & Engineering Department handles floodplain development applications and county-road driveway-pipe approvals at 2883 AL Hwy 69 N, Cullman, AL 35058, phone (256) 796-1336^1,9. The Cullman County Health Department Environmental Office handles septic applications and permits at 601 Logan Avenue, S.W., Cullman, Alabama 35055, phone 256-734-0243^5,12. We could not confirm a general county residential building-permit office outside regulated floodplain areas; ask the County Commission about that requirement. Inside city limits the city handles building permits: the City of Cullman ties its building permits and certificates of occupancy to its subdivision regulations¹³, and Arab, which reaches into Cullman County, requires building permits to erect, enlarge, alter, demolish or repair a structure¹⁴. Septic permitting remains with the Cullman County Health Department countywide⁵. County driveway-pipe and floodplain permit fees could not be confirmed; ask Road & Engineering for current charges.

Unincorporated Cullman County has no countywide zoning ordinance or county zoning permit². Cullman County sets no zoning-based minimum dwelling size, minimum lot size, building setback, lot-coverage limit or building-height limit in unincorporated areas⁸. Subdivision regulations, utility permits, driveway-pipe rules, floodplain rules and restrictions around Cullman Regional Airport can still affect a parcel². The county letter does not speak for cities: the City of Cullman has its own code of ordinances that covers zoning³, and Arab, which reaches into Cullman County, sets zoning within its city limits⁴. Septic applications and permits remain with the Cullman County Health Department countywide⁵.

The Cullman County Health Department handles local septic applications and permits within Alabama’s statewide onsite-sewage program^5,15. The Health Department also takes applications and permits for septic tanks, grease traps and holding tanks⁵. A property not connected to public sanitary sewer needs a Permit to Install before a new onsite system is installed or an existing system is repaired⁶. Submit complete applications and plans to the Health Department, wait for the Permit to Install, and use an installer licensed by the Alabama Onsite Wastewater Board⁶. Only 10.9% of Cullman County soils are rated without severe limitations for a conventional drain field, so make septic feasibility an early purchase contingency¹⁶. Where soil percolation is slower than 60 minutes or a shallow limiting zone exists, only a registered engineer may design the system¹⁷.

Unincorporated Cullman County has no county zoning rule restricting tiny-home occupancy or temporary camping¹⁸. Septic, floodplain and airport-area requirements can still apply^2,6. Long-term residential RV occupancy outside regulated flood-hazard areas could not be confirmed; ask the County Commission and Health Department about the intended use and wastewater arrangement. In areas regulated by the county flood ordinance, an RV may stay fewer than 180 consecutive days if it remains highway-ready and fully licensed if licensed, on its wheels or jacking system, attached only by quick-disconnect utilities and security devices, and without permanent additions; otherwise it must meet new-construction requirements¹¹. Inside the City of Cullman, ask the city about RV rules; we could not confirm them.

1. Confirm municipal boundaries and airport-area restrictions before relying on the unincorporated county’s no-zoning answer².
2. Ask the County Commission about general home-building permits and code requirements; the confirmed county requirement covers regulated floodplain development¹.
3. For floodplain development, submit the site plan and supporting approvals; an Alabama-licensed Professional Engineer or Land Surveyor must prepare, sign, date and stamp the application, and floodway construction requires a no-rise study¹.
4. Obtain the Health Department’s Permit to Install before septic construction and use a licensed installer⁶.
5. Confirm water service with the Cullman County Water Department at the exact parcel¹⁹.
6. For county-road driveway-pipe access, mark the location, obtain inspection and approval before placement, and arrange inspection after installation⁹.
7. An owner-builder licensing exemption requires the owner to act as contractor and personally provide all material supervision for a qualifying residence intended for the owner’s use, not sale; hiring a supervisor defeats the exemption⁷.

Check the flood map before choosing a Cullman County homesite: regulated floodplain development needs a county permit, residential lowest floors must be at least 1 foot above base flood elevation where that elevation is available, and residential floodproofing is not allowed¹. Verify water service with the Cullman County Water Department because service is not established for every tract¹⁹. New, extended or replacement driveway-pipe access on county rights-of-way requires a permit and inspections; pipe generally must be 20–60 feet long, with longer installations needing County Engineering approval⁹. If buying for cabin rentals, Alabama’s state lodgings-tax rate in Cullman County is 5% for covered transient accommodations, additional local tax may apply, and a My Alabama Taxes account is required to collect the tax; tax registration does not establish land-use permission²⁰.
