Unincorporated Dallas County, Arkansas has no building or zoning department: the state's own county directory lists only an Assessor and a Collector for the county, with nothing else1. There's also no county zoning office, so unincorporated land isn't governed by a county zoning ordinance2. Septic is a separate matter handled by the state: the Arkansas Department of Health's Dallas County Local Health Unit in Fordyce issues onsite wastewater permits and inspects installations before they're covered34.

Do you need a building permit in Dallas County, Arkansas?
No. The State of Arkansas's own county directory lists only two offices for Dallas County — an Assessor and a Collector — with no building, zoning or code-enforcement department at all1. That's consistent with most rural Arkansas counties, which have the legal option to adopt a building-permit program under state law but simply haven't1. The Arkansas Fire Prevention Code, including its residential volume, still applies statewide as a compliance standard "even in areas when no permit or inspections are required," so the code itself governs construction quality even though no one in Dallas County checks for it at a permit counter7.
Who do you call about building and land questions in Dallas County?
There's no building department to call, because Dallas County doesn't run one1. For septic, the office is the Arkansas Department of Health's Dallas County Local Health Unit in Fordyce, which administers onsite wastewater permits statewide on the county's behalf1011. For everything else, the Dallas County Judge's office is the county's central administrative office, also based in Fordyce, and the practical starting point since the county's own directory lists no dedicated zoning, planning or road department separate from it12. If your access point is a state highway rather than a county road, that's a different call again: the Arkansas Department of Transportation requires its own permit before any access driveway is built, reconstructed or modified on state highway right-of-way8.
Does Dallas County have zoning?
No. Dallas County's official directory shows no zoning or planning office, meaning unincorporated land here isn't governed by a county zoning ordinance2. That's real, but it isn't confirmation that anything goes: no official Dallas County page states a minimum lot size, setback distance, building-height limit or minimum dwelling size for unincorporated land, and none addresses manufactured homes or accessory dwellings there either2. Treat that as unconfirmed rather than as permission, and call the County Judge's office to check before you assume a use is unrestricted12.
How do septic permits work in Dallas County?
Every onsite wastewater system in Dallas County needs a construction and operation permit before installation, issued through the Arkansas Department of Health's Dallas County Local Health Unit410. The installer must notify the health unit at least 24 hours before beginning work, and the system must be inspected and approved, with the owner obtaining a permit for operation, before it can be used — emergency repairs are the one exception, and even then a permit must follow within ten working days13. Soils make this more than paperwork in Dallas County: only about 2.5% of the county's land is free of severe limitations for a conventional drain field, among the toughest septic soils tracked for this guide, so budget for a site evaluation and likely an alternative system9. State rule sets minimum separation distances too — an onsite system must stay at least 10 feet from property lines and from any dwelling or building, at least 100 feet from a domestic water supply or a stream or lake's high-water mark, and at least 300 feet from a spring or water body used as a public water supply within a quarter mile14. If a sanitary sewer is available within 300 feet of the building and reachable without crossing another person's property, state rule requires connecting to it instead of installing an onsite system15.
Can you live in an RV or tiny home on your land in Dallas County?
This isn't confirmed by an official Dallas County source, and having no zoning office doesn't settle it — no county page addresses RV occupancy, temporary camping or tiny-home occupancy on private land2. What is confirmed statewide is narrower and doesn't answer the private-land question: Arkansas requires plans for a proposed or remodeled mobile-home, tiny-house-on-wheels or RV park to be submitted to the Department of Health for approval before construction begins, but that rule governs commercial parks, not a single RV or tiny home on your own unincorporated land16. Before you plan to live in one full-time here, call the County Judge's office to ask directly12.
Building a home in Dallas County: the steps, in order
- Confirm your parcel is unincorporated. Fordyce and Dallas County's other towns may run their own building and zoning rules that don't show up in this guide, since city rules never apply outside their own limits2.
- Get a soil evaluation early. With only about 2.5% of the county's soils free of severe septic limitations, expect to need an engineered or alternative system design rather than a standard drain field9.
- Apply for an onsite wastewater permit with the Dallas County Local Health Unit before construction begins, and have the installer notify the health unit at least 24 hours before work starts10413.
- Schedule the installation inspection and get your permit for operation before using the system13.
- If your access is a state highway, apply for an Arkansas DOT driveway permit before starting any work in the right-of-way8.
- Build. Because there's no county building department, there's no county building permit, inspection or certificate of occupancy to schedule for a single-family home outside a municipality1. If you're building your own home yourself, Arkansas's residential-contractor licensing law exempts an owner constructing his or her own residence, as long as it's no more than one residence in a calendar year6.
What to check before you buy land in Dallas County
Confirm whether the parcel is unincorporated or inside a Dallas County town, since only the towns are likely to run their own permitting2. Get a soil evaluation before you count on a conventional septic field: with only about 2.5% of the county's soils free of severe limitations, an alternative system is the likely outcome, and that costs more than a standard trench system9. If a sanitary sewer already runs near the lot, check the 300-foot rule, since state rule requires connecting to it instead of installing a new onsite system15. Ask about access: a driveway onto a state highway needs an Arkansas DOT permit before any work begins8. And budget for property tax: Dallas County's effective rate is about 0.5%, with a median annual bill near $459 — among the lowest property-tax burdens tracked for this guide1718.
Watch-outs
- No official Dallas County source confirms or denies a rule on RV occupancy, temporary camping, tiny-home occupancy, minimum lot size, setbacks or building height for unincorporated land — call the County Judge's office before you build or move onto a parcel2.
- Dallas County's soils are among the toughest tracked for septic: only about 2.5% are free of severe limitations for a conventional drain field, so plan and budget for an alternative system before you commit to a site9.
