Unincorporated Dallas County, Arkansas does not appear to require a county building permit, but Arkansas building codes are mandatory statewide minimums even where no permit or inspection is required1,2. Dallas County also appears to have no county zoning for unincorporated land1. Septic permits for every address in the county, inside a city or not, come from the Arkansas Department of Health's Dallas County Local Health Unit3,4.
Do you need a building permit in Dallas County, Arkansas?
Unincorporated Dallas County does not appear to require a county building permit.
Unincorporated Dallas County does not appear to require a county building permit1. Arkansas building codes are nevertheless mandatory statewide minimums and apply even where no permit or inspection is required2. The Arkansas Fire Prevention Code, 2021 Edition, supplies the statewide building and residential standards in Dallas County, effective January 1, 2023, and any city or county may adopt stricter provisions on top of it12. Hiring a contractor does not change that: a licensed contractor who ignores the code can face discipline from the Arkansas Contractors Board or Residential Contractors Committee2. We could not confirm a general county inspection or certificate-of-occupancy process for private construction; ask the Dallas County Judge's Office whether a particular project triggers a county procedure1.
Who do you call about building and land questions in Dallas County?
Dallas County does not list a building or code-enforcement department for unincorporated construction.
Dallas County does not list a building or code-enforcement department for unincorporated construction1. The Dallas County Judge's Office is the practical first call for parcel-specific building, land-use, floodplain and county-road questions because the county directory provides that central contact1. The Arkansas Department of Health's Dallas County Local Health Unit in Fordyce handles onsite wastewater permitting and inspections3,4. A state floodplain-development rule found here applies to development proposed by an Arkansas department, not to every private Dallas County project, so private floodplain requirements still need parcel-specific confirmation13.
Does Dallas County have zoning?
Dallas County appears to have no county zoning ordinance for unincorporated land, although Arkansas law lets a county planning board adopt one for all or part of its unincorporated area.
Dallas County appears to have no county zoning ordinance for unincorporated land1, although Arkansas law lets a county planning board adopt one for all or part of its unincorporated area14. That answer does not establish that every use is unrestricted: we could not confirm county rules for general minimum lot size, building setbacks, height, minimum dwelling size, manufactured homes or accessory dwellings. Septic facilities have separate statewide siting rules, including minimum separation from property lines, buildings and water sources15. Ask the Dallas County Judge's Office about the parcel and any recorded subdivision restrictions before relying on the apparent absence of county zoning1. Incorporated places such as Fordyce, Carthage and Sparkman may set their own zoning and building rules, which we could not confirm, so check whether the parcel is inside city limits; septic permits stay with the Dallas County Local Health Unit either way4.
How do septic permits work in Dallas County?
Every onsite wastewater system in Dallas County needs construction and operation permits before installation and use, through the Arkansas Department of Health's Dallas County Local Health Unit.
Every onsite wastewater system in Dallas County needs construction and operation permits before installation and use, through the Arkansas Department of Health's Dallas County Local Health Unit3,4. Only about 2.5% of county soils are rated without severe limits for a conventional drain field, so obtain the site evaluation before fixing the house location11. Septic facilities generally must remain at least 10 feet from a building and property lines, 100 feet from a domestic water supply and 100 feet from a stream or lake high-water mark; local conditions can require more distance15. A surface-discharging system requires at least 3 acres, while an approved drip-dispersal design can support a 0.5-acre subdivision lot; these are wastewater thresholds, not general zoning minimums16,17. A subdivision that will use standard onsite systems must submit its overall wastewater plan to the Department of Health, and unsuitable parcels must be folded into surrounding lots15.
Can you live in an RV or tiny home on your land in Dallas County?
We could not confirm a Dallas County rule that generally allows or prohibits living in one RV or tiny home on private land.
We could not confirm a Dallas County rule that generally allows or prohibits living in one RV or tiny home on private land. Arkansas's confirmed rule is narrower: a parcel with at least three occupied or intended RV, tiny-house-on-wheels or mobile-home spaces, coupled with placement or maintenance services for a fee, is regulated as a park9. Proposed or remodeled parks need Department of Health plan approval before work begins, and that rule does not give an individual tiny home outside a park any county land-use permission18. Off-grid sanitation is not a free-form alternative: only premanufactured composting or incinerating toilets authorized by the Department of Health may be used, and other wastewater still must be handled under the onsite-wastewater rules19. Ask the Dallas County Judge's Office about a single unit or private campsite before moving onto the parcel1.
Building a home in Dallas County: the steps, in order
Confirm that the parcel is outside municipal limits and ask the Dallas County Judge's Office about parcel-specific county requirements.
- Confirm that the parcel is outside municipal limits and ask the Dallas County Judge's Office about parcel-specific county requirements1.
- Plan the house to the Arkansas Fire Prevention Code even though unincorporated Dallas County does not require a county building permit1,2.
- Get a soil evaluation early because only about 2.5% of county soils are rated without severe limitations for a conventional drain field11.
- Reserve enough room for the septic design and its required separation from buildings, property lines and water sources15.
- Apply through the Dallas County Local Health Unit before septic installation, pay the applicable review fee, then obtain inspection approval and the operation permit before use3,4,20.
- If the project creates lots that will use onsite wastewater, submit the subdivision wastewater plan for state review before treating those lots as buildable15.
- If acting as your own residential contractor, use the state licensing exemption only for your own residence and no more than one residence in a calendar year; it is a licensing exemption and does not excuse the building code2,6.
What to check before you buy land in Dallas County
Confirm whether the parcel is unincorporated and ask the Dallas County Judge's Office about access, floodplain review and any parcel-specific land-use issue.
Confirm whether the parcel is unincorporated and ask the Dallas County Judge's Office about access, floodplain review and any parcel-specific land-use issue1. Get a soil evaluation before choosing the building site because only about 2.5% of Dallas County soils are rated without severe limitations for a conventional drain field11. Check for sewer before designing septic: a qualifying sanitary sewer available within 300 feet must be used3. Ordinary private domestic-well permitting is unconfirmed, but public and semi-public wells need written Department of Health approval before construction, while a vertical closed-loop well needs written Commission approval and normally must remain 50 feet from septic components and drinking-water wells7,8. Dallas County's effective property-tax rate is about 0.5%, and the median annual bill is about $45911.
Watch-outs
- A single RV or private campsite is not answered by the state RV-park rules; ask the Dallas County Judge's Office before treating the absence of confirmed county zoning as permission1,9,10.
- Only about 2.5% of Dallas County soils are rated without severe limitations for a conventional drain field, so complete the site evaluation before committing to a house location11.
