Unincorporated Marshall County, Alabama requires a Permit to Develop for regulated subdivision development and a development permit before work in designated flood areas within those subdivisions1. We could not confirm a general residential building permit for other unincorporated parcels. Guntersville issues its own building permits and sets its own zoning, as do Albertville, Boaz and Arab for zoning2,3; septic permits everywhere in the county, cities included, come from the Marshall County Health Department4,5.
Do you need a building permit in Marshall County, Alabama?
Marshall County requires a Permit to Develop when building is part of regulated subdivision development in the county's subdivision jurisdiction; the County Commission must approve the proposed plat before the County Engineer issues the permit.
Marshall County requires a Permit to Develop when building is part of regulated subdivision development in the county's subdivision jurisdiction; the County Commission must approve the proposed plat before the County Engineer issues the permit1. The documented permit costs $25 and is valid for one year, with resubmittal required if work has not begun by then1. Within a regulated subdivision's designated 100-year flood area, a separate development permit is required before building, filling, grading, excavation, storage, or accessory-building work begins1. We could not confirm a general residential building permit or general building inspections for every other unincorporated parcel1. Inside Guntersville, the city's Building Department handles building permits for structures erected, moved, altered or enlarged, and no permit may issue for work that violates the zoning ordinance2. Elsewhere, ask Marshall County Engineering which of these rules applies to the tract13.
Who handles building-permit and subdivision questions in Marshall County?
Marshall County Engineering is the practical first call for subdivision-plan review, flood-ordinance administration, county-road drainage, and access questions.
Marshall County Engineering is the practical first call for subdivision-plan review, flood-ordinance administration, county-road drainage, and access questions13. The office is at 424 Blount Ave. Suite 305, Guntersville, AL 35976, and its phone number is (256)571-771213. For regulated subdivision development, the County Engineer reviews the application and the County Commission approves the proposed plat before the Engineer issues a Permit to Develop1. The published subdivision fee schedule includes a $25 Permit to Develop fee, a $200 proposed-plat review fee, and a $20 fee per lot, site, or unit; major subdivisions also carry a $0.25-per-linear-foot road fee1. These are subdivision charges, not a general house-building fee1.
Does Marshall County have zoning?
We could not confirm a countywide zoning ordinance for unincorporated Marshall County; ask Engineering about subdivision jurisdiction before assuming a rural parcel is unrestricted.
We could not confirm a countywide zoning ordinance for unincorporated Marshall County; ask Engineering about subdivision jurisdiction before assuming a rural parcel is unrestricted8,13. Albertville adopted a new zoning ordinance and map in February 2026 for properties within its corporate limits3. Guntersville zones land inside its city limits, and its Building Department provides zoning information and keeps the adopted regulations on file2,14. Boaz and Arab also administer their own city zoning6,7. Septic applications stay with the Marshall County Health Department even inside Guntersville4,5. County subdivision jurisdiction generally excludes municipal corporate limits and territory under an organized, functioning municipal planning commission3. For a Guntersville parcel, confirm the district on the city's zoning map and ordinance with the Building Department; for an Albertville parcel, use the city's adopted zoning map and ordinance3,14.
How do septic permits work in Marshall County?
The Marshall County Health Department handles onsite-sewage applications and permits for county residents.
The Marshall County Health Department handles onsite-sewage applications and permits for county residents5. Alabama homeowners and businesses off public sanitary sewer must obtain a local health-department permit before installing or repairing an onsite system; construction may begin only after the Permit to Install is issued9. Professional soil testing or system design may be required9. The same office handles septic permits for addresses inside Guntersville and Boaz4,15. Call the Environmental Office at 256-582-4926 or visit 150 Judy Smith Drive, Guntersville, Alabama 3597612. Only 21.1% of county soils are rated without severe limitations for a conventional drain field, so make septic feasibility a purchase contingency16.
Can you live in an RV or tiny home on land in Marshall County?
We could not confirm a Marshall County rule that generally allows or prohibits living in an RV or tiny home on a private unincorporated parcel.
We could not confirm a Marshall County rule that generally allows or prohibits living in an RV or tiny home on a private unincorporated parcel8. Albertville and Guntersville have zoning ordinances for land inside their city limits, so a private-lot occupancy answer outside those cities does not settle an address inside them2,3. Marshall County regulates RV parks, campgrounds, and tiny-home parks through subdivision utility provisions, which do not answer private occupancy on one parcel1. In a regulated park or subdivision, applicants must show that proposed utilities are adequate, and plats involving septic systems or wells require Health Department approval certificates1. Ask Engineering which jurisdiction applies and ask the Health Department about wastewater before buying for RV or tiny-home occupancy12,13.
How do you build a home in Marshall County, step by step?
If the land is inside Guntersville, start with the city Building Department for building permits and zoning; otherwise ask Marshall County Engineering whether the parcel is in county subdivision jurisdiction, a municipal planning area, or a designated flood area.
- If the land is inside Guntersville, start with the city Building Department for building permits and zoning2; otherwise ask Marshall County Engineering whether the parcel is in county subdivision jurisdiction, a municipal planning area, or a designated flood area1,13.
- If the project is regulated subdivision development, obtain proposed-plat approval and the county Permit to Develop before construction1.
- If the site is in a regulated subdivision's designated flood area, obtain the development permit before building, grading, filling, excavation, storage, or accessory-building work1.
- For other unincorporated parcels, ask Engineering to confirm the building-permit and inspection answer because a general requirement was not established1,13.
- Apply to the Marshall County Health Department before installing or repairing an onsite sewage system9,12.
- Confirm access early: regulated subdivision lots ordinarily need at least 30 feet of access to the building site, while specified excluded or further-dividable lots need 60 feet1.
- Alabama's owner-builder licensing exemption, which covers Marshall County including unincorporated areas, requires you to personally provide all material supervision of a one- or two-family residence on your property for your own use, not for sale, and cannot be passed to an agent; hiring a paid supervisor defeats the exemption10. Subcontractors whose portion exceeds $10,000 still need a license, and selling or offering the home for sale within one year after completion is presumptive evidence of building for sale10.
What should you check before buying land in Marshall County?
Start with wastewater: only 21.1% of Marshall County soils are rated without severe limits for a conventional drain field, and the Health Department decides onsite-system applications.
Start with wastewater: only 21.1% of Marshall County soils are rated without severe limits for a conventional drain field, and the Health Department decides onsite-system applications5,16. Check the subdivision plat and flood mapping because a development permit is required before work begins in a regulated subdivision's designated 100-year flood area1. Verify legal access because regulated subdivision lots ordinarily need 30 feet of access, with 60 feet required in specified cases1. If the tract will be divided, ask whether an exclusion applies: qualifying family divisions, certain larger tracts, qualifying single-lot conveyances, and agricultural roads or buildings may fall outside the subdivision definition, subject to stated conditions1. Finally, budget around an effective property-tax rate near 0.4% and a median annual bill of about $69916.
Watch-outs
- A subdivision Permit to Develop is not proof that every unincorporated home needs a general building permit; ask Engineering about the exact parcel1,13.
- Marshall County's driveway standards cited here apply to regulated subdivision access, not necessarily every existing individual driveway1.
- The agricultural exclusion is from the county subdivision definition; it does not waive septic, floodplain, building, or other applicable requirements1.
- Claiming Alabama’s owner-builder exemption jeopardizes Homeowners’ Recovery Fund and other Home Builders Licensure Law protections10.
