Boone County, Arkansas does not have a confirmed countywide building-permit answer for unincorporated land, but Arkansas building-code minimums apply even where permits or inspections are not required12. Countywide zoning is also unconfirmed3.

Do you need a building permit in Boone County, Arkansas?
Boone County does not have a confirmed countywide answer on whether a house in an unincorporated area needs a local building permit1. Arkansas building-code minimums apply statewide even in places where permits or inspections are not required, but that rule does not create one universal permit process213. A separate state rule requires code compliance for construction governed by that rule, but it does not establish general Boone County residential-code adoption14. Before ordering plans or starting work, call Boone County government at 870-741-5760 and ask which authority has jurisdiction over the parcel and project15. Inside Harrison, the city lists the 2021 International Building Code and fire and mechanical codes, the 2020 electrical code, and the 2018 plumbing and fuel-gas codes16. Harrison personnel also conduct code enforcement and inspect those building systems17.
Who handles building permits in Boone County, and how do you reach them?
We could not confirm a dedicated Boone County building department for unincorporated land, so start with Boone County government at 220 N Arbor Drive, Harrison, AR 72601, or call 870-741-5760 for the responsible authority15. Ask separately about structural, electrical, plumbing, mechanical, floodplain, and county-road approvals because the statewide building-code rule does not identify one local inspector or permit issuer18. Harrison's Community Risk Reduction Division performs municipal inspections, but that applies inside Harrison rather than throughout unincorporated Boone County17. New businesses in Harrison also face a municipal occupancy inspection, not a countywide residential requirement19.
Does Boone County have zoning?
We could not confirm whether county zoning applies throughout unincorporated Boone County, so do not treat rural land as unrestricted3. Boone County government is the place to ask which office can confirm zoning, setbacks, minimum dwelling size, building height, lot coverage, and floodplain review for a specific parcel15. Inside Harrison, planning and zoning are administered by the city Planning Commission and Board of Zoning Adjustment20. Harrison publishes a zoning code and current zoning map, but those city materials do not automatically apply to unincorporated Boone County21. Wastewater planning for subdivisions is also regulated under state health rules, which is separate from a complete county subdivision or zoning ordinance22.
How do septic permits work in Boone County?
Arkansas generally requires Boone County owners to obtain a Permit for Construction before installing, altering, repairing, or extending an onsite wastewater system, then obtain a Permit for Operation after inspection and approval23. The Arkansas Department of Health or its Authorized Agent administers approval; contact the Boone County Local Health Unit at 1622 Campus, Harrison, AR 72601, or (870) 743-52442425. A Designated Representative completes the construction-permit application, and review fees run from $30 to $150 by structure size2627. One exemption covers a system on a tract of at least 10 acres when its field line or disposal line is at least 200 feet from the property line; other state or federal requirements may still apply5. Only 4.3% of Boone County soils are rated without severe limits for a conventional drain field28. If sanitary sewer is available within 300 feet of the building's sewer exit without crossing another person's property, the premises must connect and cannot use an onsite system or privy2930.
Can you live in an RV or tiny home on your land in Boone County?
We could not confirm a Boone County rule allowing or prohibiting full-time RV or tiny-home occupancy on a private rural parcel, so ask Boone County government before moving a unit onto the land15. Arkansas's confirmed RV rule concerns paid parks with three or more spaces; it does not answer whether one owner may occupy one RV on private land10. The park framework includes tiny houses on wheels but does not create a general approval or ban outside a qualifying park11. Sanitation remains a separate issue: an available sanitary sewer within 300 feet requires connection when it can be reached without crossing another person's property, and an onsite system or privy cannot be used in that situation2930.
Building a home in Boone County: the steps, in order
- Call Boone County government at 870-741-5760 to identify the authority for building, zoning, floodplain, and county-road access on the parcel15.
- Confirm whether the parcel lies inside a municipality, because Harrison has its own zoning, adopted codes, and inspection program201617.
- Determine whether an available sanitary sewer requires connection before designing an onsite system29.
- Contact the Boone County Local Health Unit at (870) 743-5244 and have a Designated Representative prepare the septic construction-permit application, unless the health unit confirms the acreage exemption applies25265.
- When a septic permit is required, arrange the inspection and obtain the Permit for Operation before using the system23.
- Design for Arkansas's statewide building-code minimums even if no local permit or inspection is required2.
- If the driveway joins a state highway, obtain an Arkansas Department of Transportation permit before beginning work in the right-of-way31.
What should you check before buying land in Boone County?
Put septic feasibility near the top of the due-diligence list because only 4.3% of Boone County soils are rated without severe limits for a conventional drain field28. Terrain is mixed: 67.2% of county land has a slope of 15% or less, while 49.2% is wooded, so inspect the actual homesite, access route, and drain-field area3233. Boone County's effective property-tax rate is 0.5%, with a median annual bill of $9043435. Before closing, ask the county about zoning, floodplain, setbacks, and county-road access15. Ask the health unit whether sewer availability, the acreage exemption, or subdivision wastewater review changes the plan; subdivision plans using standard onsite systems require state health review and approval29536. A state-highway entrance requires an Arkansas Department of Transportation access permit31.
Watch-outs
- Do not mistake statewide building-code coverage for a universal building-permit requirement; Boone County's unincorporated-area permit authority must be confirmed for the specific project213.
- Do not apply Harrison's municipal inspection and occupancy rules automatically to unincorporated Boone County land1719.
- Owner-builder relief does not waive local permits, inspections, septic approval, or other building-code requirements9.
- Do not assume every Boone County septic system needs a permit: the state rule exempts a qualifying system on a tract of at least 10 acres when the disposal line stays at least 200 feet from the property line5.
