Building permits, zoning and land rules in Calhoun County, Arkansas

Unincorporated Calhoun County does not require a county building permit for a home¹. That answer concerns permit administration, not construction standards: the Arkansas Fire Prevention Code applies statewide and includes building and residential codes^2,3. An owner acting as contractor on the owner's residence is exempt from residential-builder licensing unless the owner builds more than one residence in a calendar year; the exemption does not waive permits or codes⁷. Nonresidential farm buildings also have a limited exemption from state electrical-code licensing requirements, not a blanket exemption from other land or construction rules⁹.

Inside Hampton city limits, new structures, footprint changes and demolition require a city permit⁴. Hampton City Hall issues those permits and answers questions about work inside city limits⁴. Calhoun County inspection stages and a general certificate-of-occupancy process could not be confirmed; ask the courthouse and the relevant city before construction¹.

Calhoun County has no county building office identified in the state directory, supporting the finding that a home on unincorporated land needs no county building permit¹. The Calhoun County Courthouse is the first call for parcel-specific floodplain, road or land-use questions that remain unconfirmed¹.

For work inside Hampton, Hampton City Hall issues building permits during normal business hours, with a fee of $5.00 for the first $1,000 of building cost and $2.50 per $1,000 after that⁴. Hampton's permit does not cover septic, which stays with the state health program below. For septic, the Arkansas Department of Health Onsite Wastewater Program sets statewide policy and assists county environmental health specialists⁶. Applications go to a local Authorized Agent where one is designated, or to the Department where none exists¹⁰. Calhoun County's specific Authorized Agent could not be confirmed, so contact the state program for the correct route before ordering a soil evaluation⁶.

We could not confirm that Calhoun County has adopted countywide zoning for unincorporated land. The state directory identifies no county planning or zoning office¹, but an absent office listing does not settle parcel-level rules. Ask the Calhoun County Courthouse about building setbacks, lot coverage, height, minimum dwelling size and private-land accessory dwellings before buying or siting a structure¹. Arkansas's statewide accessory-dwelling rule applies within municipalities and requires them to allow at least one qualifying accessory dwelling on a parcel with a single-family home; it does not create an accessory-dwelling right on unincorporated county land¹¹.

Hampton's permit ordinance covers new construction, footprint changes and demolition inside city limits⁴. Hampton also sets separate lot, spacing, installation and utility standards for manufactured homes within the city¹². Verify jurisdiction from the deed, survey and tax parcel rather than relying only on a Hampton mailing address.

Calhoun County septic systems fall under the Arkansas Department of Health framework. The Department or its Authorized Agent issues construction and operation permits; applications go to a designated local agent where one exists and otherwise to the Department¹⁰. State individual sewage-disposal permit fees run from $30 to $150 based on structure size; these are septic fees, not a Calhoun County building-permit schedule¹³. A completed application and plans must be approved before construction of a building or residence, and emergency repairs may start first only if a permit follows within 10 working days^5,14. Onsite wastewater components generally must be at least 10 feet from buildings and property lines, 100 feet from a domestic water source and 100 feet from a stream or lake high-water mark, with other water-body conditions and possible greater site-specific distances¹⁵.

A new well must sit at least 50 feet from any lot line and at least 100 feet from any part of a proposed onsite wastewater system¹⁰. A permit is refused where public sewer is reasonably available or economically feasible¹⁰. Surface-discharge systems require at least 3 acres plus applicable setbacks¹⁰. In subdivisions using onsite wastewater, construction cannot begin on a lot until the Department approves the wastewater submission; drip-dispersal lots must be at least 0.5 acre^10,16. Only about 2.5% of county soils avoid severe conventional-drain-field limitations, so make the soil evaluation an early purchase contingency¹⁷.

We could not confirm a Calhoun County rule that generally allows or prohibits full-time living in one RV or tiny home on an individual private parcel. The county directory identifies no planning or zoning office¹, but that does not answer occupancy, utility, sanitation, setback or floodplain questions. Ask the Calhoun County Courthouse for the parcel's rule, and ask the relevant city if the property is incorporated¹.

Arkansas's park rules answer a different question. A recreational-vehicle park reaches the regulated threshold at 3 or more transient-dwelling spaces or qualifying spaces supported by fee-based placement or maintenance services, and Department-approved plans are required before construction, alteration, repair or expansion¹⁸. A tiny house on wheels in that setting is treated as a mobile home if plumbed and inspected under the Arkansas Plumbing Code, and as an RV if it is not¹⁹. The park rule does not decide whether temporary camping is allowed on one private parcel¹⁹. Composting or incinerating toilets must be Department-authorized, while other wastewater still needs approved handling¹⁰.

1. Confirm whether the parcel is unincorporated or inside Hampton; Hampton requires permits for new structures, footprint changes and demolition⁴.
2. For unincorporated land, confirm the county permit answer and ask the courthouse about private-development floodplain and road requirements¹. The state floodplain permit identified in the rules is for state capital projects and does not establish Calhoun County's process for private development²⁰.
3. Design to statewide construction standards even if no county permit or inspection is required⁷.
4. Determine whether public sewer is available before designing septic; an available sewer can rule out an onsite permit¹⁰.
5. Route septic approval through the Department of Health or its Authorized Agent before construction¹⁰.
6. An owner building the owner's residence may use the licensing exemption if no more than one residence is built in the calendar year, but applicable permits and codes remain⁷.
7. Obtain an Arkansas Department of Transportation permit before working on state-highway right-of-way²¹.

Put septic feasibility near the top of the purchase contract: only about 2.5% of Calhoun County soils avoid severe conventional-drain-field limitations¹⁷. About 99.2% of land has a slope of 15% or less¹⁷, but gentle ground does not guarantee suitable soil or drainage. About 88.9% of the county is wooded, so price clearing and access before closing¹⁷.

Confirm legal access and road ownership. A driveway entering state-highway right-of-way needs an Arkansas Department of Transportation permit before work begins²¹. A separate private household-well permit could not be confirmed; state approval is expressly required for public and semi-public wells, so ask the Arkansas Department of Health and a licensed well contractor about a domestic well⁸. The median property-tax bill is about $485 per year, with an effective rate near 0.5%¹⁷.
