Do you need a building permit in Houston County, Alabama?
Yes. Houston County requires a $100 building permit for house construction in the unincorporated county before work begins1. The application package requires the completed county form, approved Health Department onsite-sewage installation permit where applicable, and a plot plan or survey showing the structure footprint9. Houston County does not perform residential building inspections and consequently cannot issue a certificate of occupancy23. The county permit is still required even though it does not lead to routine county inspections or a county occupancy certificate12. Alabama's owner-builder licensing exemption can cover an owner who personally acts as contractor and provides all material supervision on a qualifying home for the owner's own use, but it does not waive Houston County's permit7.
Who issues Houston County building permits, and how do you reach the office?
The Houston County Road & Bridge Department is the permit counter for building, driveway, mobile-home moving, utility-work and flood-zone matters10. Reach Road & Bridge at 334-792-4149 or visit 2400 Columbia Hwy. Dothan, AL 36303; its posted hours are Monday through Thursday, 7:00 a.m. to 4:00 p.m.10. Houston County publishes an online application, and the house-permit package includes the completed form, Health Department septic approval where applicable, a plot plan or survey, and the fee911. Houston County performs no residential building inspections and therefore issues no certificates of occupancy23. Ask Road & Bridge which adopted building-code requirements apply, because we could not confirm the code edition for unincorporated construction. Inside a city, ask city hall which office issues building permits and zoning approval; septic permits for property off public sewer still come from the Houston County Health Department4.
Does Houston County, Alabama have zoning?
Houston County's zoning status for unincorporated land remains unconfirmed5. Alabama counties lack broad, general land-use authority under general state law, although local laws and specific statutes can create limited authority12. That statewide limit does not prove that a Houston County parcel is unrestricted. Ask the Houston County Commission whether the parcel is affected by a local law, floodplain rule, airport restriction, subdivision condition or municipal jurisdiction. Houston County regulates subdivision plats outside municipal boundaries, and the County Commission is the official platting authority13. Subdivision plats must show building setback lines.14 In a platted subdivision, residential lots must meet Health Department minimum dimensions and a front setback line of 20 feet unless the County Commission approves otherwise15. A rural subdivision seeking the curb-and-gutter exception needs lots of at least 2.5 acres with 250 feet of road frontage; that is a condition of the exception, not a minimum for every parcel16. We could not confirm general rules for minimum dwelling size, accessory dwellings, lot coverage or building height. City zoning, where a city has it, applies only inside city limits, so ask city hall for those parcels.
How do septic permits work in Houston County?
The Houston County Health Department administers onsite-sewage permitting for property not connected to public sanitary sewer4. A local Health Department permit is required before installing a new onsite system or repairing an existing one, so an off-grid plan still needs an approved sanitation system617. The application calls for professional soil information, a legal description, plot plan, vicinity map and, when applicable, a construction plan; the Health Department reviews the application and soil results before issuing a permit6. Contact the Houston County Health Department Environmental Office at 334-678-2815 or 1781 East Cottonwood Road Dothan, Alabama 3630118. Septic comes before the house permit because Road & Bridge requires Health Department approval in the permit package where applicable9. Only about 22.4% of Houston County soils avoid a "very limited" rating for conventional septic drain fields, so make the site and soil review an early purchase contingency19.
Can you live in an RV or tiny home on land in Houston County?
We could not confirm a Houston County rule for RV occupancy, temporary camping or tiny-home occupancy on private land. Houston County's zoning status is also unresolved, so the absence of a confirmed rule is not permission to live in an RV or tiny home on every rural parcel5. Ask the Houston County Commission about occupancy limits for the exact parcel and Road & Bridge whether a proposed tiny home needs the county house permit. Any off-grid residence not connected to public sewer still needs Health Department approval before a new onsite sewage system is installed17. A manufactured home is a separate legal category from an RV or site-built tiny home; Alabama recognizes a qualifying manufactured home for residential use subject to required utility connections and applicable local rules20. Houston County publishes a $100 charge for installing a mobile home when it moves on county roadways11.
Building a home in Houston County: what are the steps?
- Ask the Houston County Commission whether parcel-specific zoning or land-use restrictions apply, because countywide zoning remains unconfirmed5.
- Confirm that the lot is a lawful split; Houston County regulates subdivision plats outside municipal boundaries13.
- Contact the Houston County Health Department for soil review and the onsite-sewage application when public sewer is unavailable6.
- Obtain the Health Department permit before septic installation or repair and before submitting the county house-permit package69.
- Submit the completed building application, septic approval where applicable, plot plan or survey, and $100 fee to Road & Bridge before construction starts1.
- For a flood-zone site, include the additional $50 permit and plans; Houston County checks elevation after the lowest floor is installed and before walls rise8.
- Plan separately for any specialty or third-party inspections because Houston County does not perform residential building inspections or issue certificates of occupancy23.
What should you check before buying land in Houston County?
Start with wastewater feasibility: only about 22.4% of Houston County soils avoid the most restrictive conventional-drain-field rating, and Health Department approval belongs in the house-permit package when onsite sewage applies199. Check flood maps early because a flood-zone house needs a $50 county floodplain permit, plans and an elevation check during construction8. Every regulated subdivision needs access over a public street, road or highway, with separate-driveway conditions applying to certain subdivision exceptions21. A parcel used solely for agriculture can get a county driveway pipe through a Road & Bridge agreement only if the owner promises not to build a residence for at least two years22. Access onto an Alabama state highway requires an ALDOT turnout permit23. For a newly divided rural tract, request evidence of Houston County subdivision approval rather than assuming the deed settled development eligibility13. We could not confirm ordinary private-well permitting, so ask the Health Department and relevant water authority about water options. Houston County's effective property-tax rate is about 0.3%, with a median annual property-tax bill of about $5342425.
Watch-outs
- Houston County requires the house permit but performs no residential building inspections and issues no certificates of occupancy, so ask Road & Bridge what proof lenders, insurers and utility providers will expect123.
- Houston County zoning, RV occupancy, tiny-home occupancy, private-well permitting and the locally adopted residential-code edition remain unconfirmed; ask the County Commission, Road & Bridge and Health Department before committing to a use5.
- Beginning January 1, 2027, residential builders must follow the applicable Alabama Residential Building Code or a qualifying local residential code, so confirm current requirements with Road & Bridge near that transition26.
