Unincorporated Houston County, Alabama requires a $100 building permit before construction of a house begins1. The Road & Bridge Department issues the permit, but Houston County does not perform residential building inspections or issue certificates of occupancy23. An approved onsite-sewage permit and a plot plan or survey showing the house footprint belong in the building-permit package1.

Do you need a building permit in Houston County, Alabama?
Yes. Houston County requires a $100 building permit for residential house construction in the unincorporated county, and the permit must be received before construction starts1. The application package requires the completed county form, approved Health Department onsite-sewage installation approval, and a plot plan or survey showing the structure footprint1. Houston County does not perform county residential building inspections and consequently cannot issue a certificate of occupancy23. That distinction matters: obtaining the county permit is required even though it does not lead to routine county building inspections or a county occupancy certificate12. Alabama's owner-builder licensing exemption may cover an owner acting as the contractor on a one-family or two-family residence intended for the owner's own use, provided the owner personally supplies all material supervision9.
Who issues Houston County building permits, and how do you reach the office?
The Houston County Road & Bridge Department is the practical 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 also publishes an online building-permit application, but completed applications must be sent with payment to Road & Bridge before construction begins11. The county accepts check, cashier's check or money order and does not accept cards for that application11. For the unusual inspection question, Houston County's answer is direct: the county performs no residential building inspections and therefore issues no certificates of occupancy23. Ask Road & Bridge which adopted building-code requirements apply, because the reviewed county materials do not identify the code edition for unincorporated construction.
Does Houston County, Alabama have zoning?
Houston County's zoning status for unincorporated land remains unconfirmed in the reviewed official material6. Alabama counties do not receive broad, general land-use authority under general state law, although limited authority can exist through local laws and specific statutes12. That statewide limit is not proof that a particular Houston County parcel has no restrictions. Before treating rural land as unrestricted, ask the Houston County Commission whether the parcel is affected by any local law, floodplain rule, airport-related restriction, subdivision condition or municipal jurisdiction. Houston County does regulate subdivision plats outside municipal boundaries, with the County Commission serving as the official platting authority13. We could not confirm countywide rules for setbacks, minimum dwelling size, minimum lot size, accessory dwellings, lot coverage or building height. A recent land split should therefore be checked separately from zoning, because subdivision approval can matter even when the broader zoning answer is unresolved13.
How do septic permits work in Houston County?
The Houston County Health Department administers onsite-sewage permitting for property in Houston County4. A property not connected to public sanitary sewer needs a local Health Department permit before a new onsite system is installed or an existing system is repaired5. 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 permit to install5. Contact the Houston County Health Department Environmental Office at 334-678-2815 or 1781 East Cottonwood Road Dothan, Alabama 3630114. Septic comes before the house permit because Road & Bridge requires approved Health Department onsite-sewage installation approval in the building-permit package1. 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 contingency rather than assuming a conventional field will work15.
Can you live in an RV or tiny home on land in Houston County?
The reviewed official sources do 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 located rule is not permission to live in an RV or tiny home on every rural parcel6. Ask the Houston County Commission about land-use and occupancy limits for the exact parcel, and ask Road & Bridge whether the proposed structure needs the county house permit. Any residence using onsite sewage still needs the Houston County Health Department process when it is not connected to public sanitary sewer5. A manufactured home is a separate legal category from an RV or a site-built tiny home: Alabama allows a qualifying manufactured home as a residence when it bears the required HUD seal, has the required utility connections and is installed by a certified installer, subject to applicable local rules16. Houston County separately publishes a $100 charge for moving a mobile home on county roadways17.
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 unconfirmed6.
- 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 unavailable5.
- Obtain the Health Department permit to install before septic work and before applying for the county house permit51.
- Submit the completed building application, septic approval, plot plan or survey, and $100 fee to Road & Bridge before construction starts1.
- For a mapped flood-zone site, include the additional $50 permit and required plans; Houston County checks elevation after the lowest floor is installed and before walls rise8.
- Arrange any required specialty or third-party inspections directly, 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 an approved onsite-sewage permit is part of the house-permit path when sewer is unavailable151. Check flood maps early because a flood-zone house needs a $50 county floodplain permit, plans and an elevation check during construction8. Verify driveway access too: a county-right-of-way driveway pipe must be sized and inspected by Road & Bridge, and fill cannot cover it before that inspection18. Access onto an Alabama state highway instead requires an ALDOT turnout permit19. For a newly divided rural tract, request evidence of Houston County subdivision approval rather than assuming the deed alone settled development eligibility13. Private-well permitting is unresolved for ordinary Houston County domestic wells, so ask the Health Department and the 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 $5342021.
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 use6.
- 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 transition22.
