Conway County, Arkansas is subject to statewide building-code minimums, but we could not confirm a general county residential building-permit requirement for unincorporated land12. Work subject to the Arkansas Energy Code must be inspected by the state Energy Office, its agent or the code official, though Conway County's local inspection practice remains unconfirmed3. The Arkansas Department of Health or its authorized agent administers septic permits4.

Do you need a building permit in Conway County, Arkansas?
We could not confirm a general Conway County residential building-permit requirement for unincorporated land, and the statewide source recognizes that some Arkansas areas have no permit requirement25. New structures and covered alterations still must comply with the Arkansas Fire Prevention Code, while local governments may adopt more stringent provisions from that code1. The Arkansas Energy Code is an energy-efficiency code, not a complete answer to building, zoning, septic or occupancy rules15. Work subject to that energy code must be inspected by the Arkansas Energy Office, its agent or the code official, but Conway County's local inspection practice remains unconfirmed3. Ask the Conway County Judge's office which authority reviews plans, issues building permits, conducts local inspections or documents occupancy for the parcel16. For a builder who builds or contracts to build a single-family home for personal occupancy, energy-code compliance is voluntary; that provision does not answer whether other building, electrical, plumbing, septic or floodplain permits apply10.
Who handles Conway County building and permit questions?
Conway County publishes no dedicated building or planning contact in the official service information we could verify, so begin with the Conway County Judge's Office at 117 S. Moose St., Morrilton, AR 72110, (501) 354-9640, or judge@conwaycounty.org16. Ask the office to identify the authority for building permits, inspections, floodplain review and county-road access on the parcel rather than assuming those functions do not exist. The County Judge's office also oversees the county road system, making it the practical first call when a proposed driveway meets a county road16. For onsite wastewater, call the Conway County Health Department at 501-354-4652 and ask for the onsite environmental health specialist1718. The state Onsite Wastewater Program works with local environmental specialists to review qualifying septic applications19.
Does Conway County, Arkansas have zoning?
We could not confirm a countywide zoning ordinance for unincorporated Conway County from an accessible official source6. The same gap applies to county rules for setbacks, minimum dwelling size, minimum lot size, building height and lot coverage, so ask the Conway County Judge's office what applies to the parcel before fixing a house site or ordering plans16. A lack of a confirmed county zoning rule does not answer what an incorporated city may require, and it does not cancel statewide building, septic or highway-access rules. Arkansas's building-code minimums apply statewide, including where no local permit is required5. A driveway connecting to a state highway requires an Arkansas Department of Transportation permit, while the county office should be asked about access from a county road2016.
How do septic permits work in Conway County?
The Arkansas Department of Health or its authorized agent administers Conway County onsite-wastewater permits4. Call the Conway County Health Department at 501-354-4652 and ask for the onsite environmental health specialist1718. Part I of the application is the Permit for Construction, Part II records the installation inspection, and Part III is the Permit for Operation21. Obtain the construction permit before building, altering, repairing or extending the system; after installation, the system must pass inspection and receive its operating permit before use89. Arkansas sets no single septic minimum lot size; soil suitability, bedroom count and the 100-foot well setback determine space needs18. A qualifying single residence on ten or more acres may be exempt from the permit when the entire sewage system is more than 200 feet from every property line, including roads18. Only about 7% of Conway County soils lack severe limitations for a conventional drain field, so make soil evaluation an early purchase contingency13.
Can you live in an RV or tiny home in Conway County?
We could not confirm a Conway County rule allowing or prohibiting long-term RV, tiny-home or manufactured-home occupancy on a single private parcel, so ask the Conway County Judge's office before treating the land as a legal homesite16. Arkansas regulates parcels operating as mobile-home or recreational-vehicle parks when three or more spaces are occupied or intended for occupancy and placement or maintenance services are provided for a fee11. Under those park rules, a tiny house on wheels is treated as a mobile home when plumbed and inspected under the state plumbing code, and as a recreational vehicle when it is not22. Those park provisions do not settle private occupancy outside a qualifying park. Off-grid sanitation remains regulated: onsite systems require approval, inspection and permits, while an available sanitary sewer within 300 feet of the building's sewer-exit point must be used when the connection does not cross another person's property2324.
What are the steps to build a home in Conway County?
- Ask the Conway County Judge's office which local authority covers building permits, inspections, zoning, floodplain review and county-road access for the parcel16.
- Confirm that the house design meets Arkansas's statewide building-code minimums even if no local building permit is required15.
- Call the Conway County Health Department and ask for the onsite environmental health specialist before choosing the final house and drain-field locations1718.
- Determine whether an available sanitary sewer is within 300 feet of the building's sewer-exit point and can be reached without crossing another person's property; if so, sewer connection is required and onsite sanitation may not be used2423.
- If onsite wastewater is allowed, obtain Part I approval before work, complete the Part II installation inspection, and obtain the Part III operating permit before use2189.
- Obtain the soil evaluation early because only about 7% of county soils are rated without severe limits for a conventional drain field13.
- Apply to the Arkansas Department of Transportation before constructing a driveway onto a state highway20.
What should you check before buying land in Conway County?
Start with wastewater feasibility: only about 7% of Conway County soils are rated without severe limitations for a conventional septic drain field13. If land will be divided into lots using standard onsite systems, the subdivision wastewater plan must go to the Arkansas Department of Health with soil and site information for review; that requirement does not establish a general Conway County subdivision ordinance25. The wastewater plan-review fee is $100 for the first lot plus $25 for each following lot, capped at $1,500; this is not a general county building or land-use permit fee26. The county receives about 52 inches of precipitation annually, and about 82% of its land has a slope of 15% or less, so visit after rain and verify drainage2728. Confirm legal road access and ask the County Judge's office whether a county-road entrance requires approval; a state-highway driveway requires a state permit1620. We could not confirm a Conway County floodplain-development process for private property. The available state well rule covers public and semi-public wells but does not establish a permit requirement for every private domestic well14.
Watch-outs
- Conway County's general residential permit, inspection and certificate-of-occupancy requirements were not confirmed; ask the County Judge's office which authority applies before construction16.
- Countywide zoning, setbacks, minimum dwelling size and minimum lot size for unincorporated land were not confirmed; get a parcel-specific answer from the County Judge's office616.
- An onsite wastewater system generally needs a construction permit before work and an inspection, approval and operation permit before use89.
- Available sanitary sewer within 300 feet can require connection and rule out a privy or onsite wastewater system when the connection does not cross another person's property2423.
