Buying Land in Arkansas: The State-Level Rules Before You Get to a County

Zoning in Arkansas is a county-by-county choice, not a statewide system

Arkansas Code Title 14 gives counties the authority to create a county planning board and adopt a zoning ordinance for the unincorporated parts of the county, but it doesn't require them to. Whether that authority actually gets used is decided by each county's quorum court, and it varies widely. Some counties have adopted comprehensive, county-wide zoning; a meaningful number of rural Arkansas counties have adopted little to none, meaning unincorporated land there is governed mainly by whatever a specific subdivision's deed restrictions say, plus state and federal rules (floodplain, septic, wetlands), rather than by a county zoning map.

Practically, that means the question "what can I build here?" often has a different answer depending on whether a rural Arkansas parcel is inside city limits (municipalities generally do zone) or out in the unincorporated county (zoning may be minimal or absent). Never assume either way -- call the specific county's planning office (where one exists) or the county judge's office and ask directly whether any zoning or building-permit ordinance applies to the parcel.

Water rights: Arkansas is a riparian-doctrine state, with registration above a threshold

Arkansas follows riparian water-rights doctrine (as opposed to the prior-appropriation system used in much of the arid West): a landowner's right to use water is tied to owning land that touches or overlies the water source, not to a separate permit granted on a first-come basis. For most everyday household and agricultural use this rarely becomes an issue, but Arkansas layers a registration requirement on top of pure riparian rights -- a landowner who wants to divert more than roughly 325,900 gallons (about one acre-foot) of surface water in a year has to register that use with the state's water-resources regulator.

That regulator is the Natural Resources Division of the Arkansas Department of Agriculture (the rulemaking body above it is the Arkansas Natural Resources Commission). If a land purchase involves any meaningful irrigation, pond, or commercial water use beyond ordinary household draw, checking registration and any applicable water-use rules with that division before you buy is worth the call.

Wells are a state-licensed trade, statewide, regardless of county zoning

Unlike zoning, private well construction in Arkansas is regulated uniformly statewide, not left to county discretion. Anyone drilling a well or installing a well pump must hold an Arkansas Water Well Contractor's License and the applicable Certificate of Registration, issued and enforced through the Water Well Construction Commission (also under the Department of Agriculture). A rig permit from the state is required before drilling begins. That licensing and permitting requirement applies the same way whether the county the parcel sits in has zoning or not -- it's one of the few land-use-adjacent rules in Arkansas that doesn't vary by county.

Septic approval runs through the state health department, with county-level review

Onsite wastewater (septic) systems in Arkansas are regulated by the Arkansas Department of Health under statewide rules, with day-to-day permit review and site inspection carried out by Environmental Health Specialists working out of each county health department. Arkansas requires two separate approvals for a new system: a Permit for Construction before installation, and a Permit for Operation -- issued only after the Department or its authorized agent inspects the completed system -- before it can legally be used.

Installers, cleaners, and designated representatives working on Arkansas septic systems must themselves be licensed by the Department of Health; an unlicensed installation is not just a code violation; it can leave you unable to get the operation permit you need to occupy the property. This state-run structure is worth knowing going in, since some neighboring states route the same approval through a county-run department instead.

What this means for due diligence

The single most important local call for a rural Arkansas parcel is to the county: ask directly whether any zoning ordinance, building permit requirement, or subdivision regulation applies to unincorporated land there, since "no zoning" is a real and common answer in this state, not a hypothetical one. Separately, budget for the state-run pieces -- a licensed well contractor for water, and Department of Health permitting (construction, then operation) for septic -- which apply in essentially the same way regardless of what the county-level zoning picture looks like.

If any meaningful surface-water use (irrigation, a large pond, livestock watering beyond ordinary domestic use) is part of your plan, add a check of Arkansas's riparian registration threshold to your due-diligence list alongside the standard national items in our buying-land checklist.
