Unincorporated Blount County, Alabama has no countywide residential building permit that we could confirm and no county zoning12. Floodplain development and driveways onto county roads still need county approval34. Blountsville, Oneonta and Highland Lake set their own zoning inside town limits, and Oneonta also issues its own building permits5678. Septic permits for every address, city or not, come from the Blount County Health Department9.

Do you need a building permit in Blount County, Alabama?
A general county building permit for an ordinary home in unincorporated Blount County could not be confirmed, and the county's department list has no building-permit or inspection office1. Alabama's State Building Code covers state-owned or state-funded work, schools, hotels, motels and movie theaters, but the state construction office has no jurisdiction over ordinary residential property10. Authority to adopt a residential building code moved to the Alabama Home Builders Licensure Board in October 2024, and the state's page said a code was to be presented for adoption by October 2025; that adoption does not itself create a Blount County permit17. Alabama law also lets a county commission adopt building codes for unincorporated land, but the statute does not say whether Blount County has done so18. Where a local authority does issue residential permits, it must refuse one to a builder who needs a state home-builder license and cannot show a license or exemption19. Separate county approvals still apply: development in a designated floodplain needs the County Engineer's approval, and access into a county right-of-way needs County Commission approval34. Inside a town, ask the town first: Oneonta requires written authorization from the city building inspector before construction, alteration or repair begins, except for minor repairs under $100 and painting or wallpapering8. Highland Lake inspects new construction and additions under its adopted code, and Blountsville's planning department has a building office1112.
Who handles building, driveway and septic permits in Blount County?
Unincorporated Blount County has no listed general building-permit department, so the right contact depends on the work1. The Blount County Engineering Department administers the subdivision regulations and is the county contact for subdivision, floodplain and county-road-access questions20. Reach Engineering at 6454 Second Ave. West, Oneonta, AL 35121, by phone at 205-274-2128 or by email at nalexander@blountcountyal.gov20. Blount County Health Department Environmental Services handles onsite-sewage applications and permits under Alabama's county-health-department program219. Its contact is 1001 Lincoln Avenue, Oneonta, Alabama 35121, phone 205-947-107622. Inside Blountsville, the town's planning department has its own building office12. Inside Oneonta, the city building inspector issues the written authorization that building permits require8. Highland Lake documents its own building requirements11. Septic stays with the county health office even inside Oneonta, and inside Blountsville the town's code defers lot-area questions to it1423.
Does Blount County have zoning?
Unincorporated Blount County has no county zoning authority, so county zoning does not set dwelling size, lot coverage, building height or residential-use limits there2. That does not leave every parcel free of regulation: subdivision standards can govern lots, setbacks, roads and plat approval, while floodplain, septic and driveway rules operate separately from zoning24253134. Three towns do zone. Blountsville has an adopted zoning ordinance with residential districts5. Land inside Oneonta is zoned under the city's own ordinance, administered and enforced by the city building inspector6; the Planning Commission recommends changes and the Mayor and City Council decide26. Highland Lake has a zoning ordinance and map requiring land uses and structures to follow district rules7. The county's subdivision regulations do not administer Oneonta's zoning27. Check whether the parcel sits inside town limits or a town's planning jurisdiction before relying on the unincorporated-county answer16.
How do septic permits work in Blount County?
Blount County Health Department handles local onsite-sewage applications and permits as part of Alabama's county-health-department program, which the state's Soil and Onsite Sewage Branch coordinates, and that holds for addresses inside Oneonta and Blountsville too282191423. Where public sanitary sewer is unavailable, submit a complete application and plans to the Health Department and wait for the Permit to Install before construction begins; the installer must be licensed by the Alabama Onsite Wastewater Board13. Inspection depends on the work: the local Health Department may inspect a qualifying tank or non-perforated-component repair if time allows, while a signed repair waiver means no inspection or Approval for Use29. The Health Department performs no site visit or installation inspection for an engineered small-flow system submitted on the applicable professional-engineer form30. Site suitability deserves attention before purchase because only 6.9% of Blount County soils are rated without severe limitations for a conventional septic drain field31. For residential lots in a major subdivision that lack public water or sewer, septic tanks and wells need Blount County Health Department approval on the proposed plat, and the lot size follows Health Department rules with a floor of 7,500 square feet32. The available information does not establish a general permit rule for every individual private well, so ask Environmental Services about the particular site3322.
Can you live in an RV or tiny home on land in Blount County?
County zoning does not restrict RV occupancy, tiny-home occupancy or temporary camping on unincorporated land in Blount County2. That answer is only about county zoning: ask the County Engineer about subdivision, floodplain and road-access requirements, and ask the Health Department how wastewater must be approved before using either structure as a residence202213. Inside Blountsville, Oneonta or Highland Lake, town zoning can change the answer; Blountsville's code, for example, allows a temporary mobile home or travel trailer only as business or industrial quarters in a business or industrial zone, on a 120-day permit1267. Alabama's manufactured-housing rule treats a park model, a recreational trailer of 400 square feet or less, as a recreational or seasonal unit rather than a permanent dwelling34. A manufactured home is a distinct regulated category: Alabama requires installation by a certified Alabama Manufactured Housing Commission installer and requires qualifying homes to carry the federal label and data plate35. We could not confirm a short-term-rental rule for unincorporated Blount County; ask Engineering about the proposed use20.
Building a home in Blount County: the steps, in order
- Confirm whether the parcel is unincorporated or inside a municipality, because Blountsville, Oneonta and Highland Lake have zoning, and Oneonta requires building-inspector authorization568711.
- Ask the Engineering Department whether subdivision approval, a Flood Plain Development Permit or a county-road Driveway Access Permit applies201634.
- If access is from a state highway, submit the state driveway application to the ALDOT District Administrator36.
- Confirm sewer availability; if an onsite system is needed, obtain the Health Department's Permit to Install before septic construction1322.
- Decide who will build. A qualifying owner may act as contractor for an owner-occupied one- or two-family residence by personally supervising the work, but the state licensing exemption does not erase any local permit requirement15. The exemption is nontransferable, requires the owner to supervise personally, and presumes the home was built for sale if it is offered within 1 year of completion; subcontractors must be licensed when their portion costs more than $10,00037.
- Before starting, confirm any municipal permit, inspection and occupancy requirements; where a municipality issues a certificate of occupancy, the builder must provide an updated subcontractor list first38.
What should you check before buying land in Blount County?
Start with legal access and development status. A driveway into a county right-of-way requires approval, while access to a state highway uses ALDOT's permit process436. Confirm that a newly created subdivision lot has a recorded final plat before planning construction16. Major subdivisions carry a $250 proposed-plat review fee plus $25 per lot, site or unit, while minor and rural subdivisions have no submittal fee; other inspection, testing, postage and filing costs may still apply39. Qualifying agricultural roads and buildings can be exempt from subdivision review, and a qualifying division into parcels of at least 20 acres can also be exempt, but both routes require an Exempt Subdivision Letter from the County Engineer and do not waive health, state, highway-setback or applicable municipal rules4041. Check septic feasibility early because only 6.9% of county soils are rated without severe limitations for conventional drain fields31. Land disturbance of one acre or more generally needs Alabama Department of Environmental Management construction stormwater coverage, which carries a $1,385 application fee42. Finally, confirm floodplain status, town boundaries and road classification before closing because each can change the approvals, setbacks and costs376525.
Watch-outs
- Do not read the absence of a listed county building office as proof that every project is permit-free; Blount County's general residential permit, inspection and occupancy-certificate rules remain unconfirmed1.
- Blountsville, Oneonta and Highland Lake each zone their own land and document local building requirements, so a Blount County mailing address alone does not answer which rules govern567811.
- An agricultural subdivision exemption is not automatic: obtain an Exempt Subdivision Letter from the County Engineer, and expect health, state, highway-setback and applicable municipal requirements to remain in force43.
