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

A residential building permit is not required in unincorporated Lonoke County¹. Arkansas Building Codes remain mandatory statewide minimums even where no local permit or inspection is required, so a missing permit office does not mean a missing code². The statewide code is the 2021 Arkansas Fire Prevention Code, which includes the building and residential codes, and counties and cities may only adopt and enforce that edition^8,20. Work subject to the Arkansas Energy Code may be inspected by the Arkansas Energy Office, its agent or a code official; a local final inspection applies where the county or municipality has adopted that code and conducts final inspections in its normal operations²¹.

Inside the incorporated City of Lonoke the answer changes: the city administers its own building and development codes and requires building permits for signs, storage buildings, fences, additions, remodels and all new residential or commercial construction^3,9. Cabot requires permits before residential and commercial construction starts, and Ward requires building permits for new construction, additions, remodels, fences and signs^4,5. City building permits do not take over septic: septic permits stay with the Arkansas Department of Health⁷.

For unincorporated land, the state's county listing shows no separate building, planning or zoning department, so the contact point for county government is the Lonoke County Judge's Office at the courthouse, 3rd & Center Street, Lonoke, AR 72086, 501-676-2368¹. For septic permits, call the Arkansas Department of Health's Onsite Wastewater Program, which works through an Environmental Health Specialist in the Lonoke County health department; the program's Little Rock office is at 4815 West Markham Street, Slot 46, Little Rock, AR 72205, phone 501-661-2171²². For building permits inside the City of Lonoke, contact the city's Community Development Department at 107 West Second Street, Lonoke, AR 72086, phone 501-676-4300 ext. 2; applications go through the city's Administration Office³. For Cabot and Ward, call the city's own permit office rather than the county; the county's portal lists no building department for unincorporated land^4,5. If your driveway connects to a state highway, the Arkansas Department of Transportation's district office issues the driveway permit²³.

Zoning approval in Lonoke County varies by location, and we could not confirm a county-administered zoning ordinance for land outside incorporated municipalities^1,6. Ask the County Judge's Office about zoning, subdivision rules, setbacks, minimum home size and flood requirements for a specific unincorporated parcel¹. The City of Lonoke's zoning applies only within its corporate limits, although its separate development and subdivision provisions can reach property served by city utilities in its planning area⁹. The City of Lonoke's published districts include residential, manufactured-housing, agricultural, commercial and industrial districts⁹. The City of Lonoke's planning page lists zoning applications for conditional uses, rezoning and variances⁹. The City of Cabot also runs its own zoning, with rezoning and variance permits, only within Cabot's corporate limits¹⁰. Ward replaced its early-1990s zoning rules with a Unified Development Ordinance effective January 1, 2026¹¹. Arkansas law lets a county planning board zone all or part of its unincorporated area, but we could not confirm that Lonoke County has done so^6,24. Within the City of Lonoke, a single-family dwelling must have at least 500 square feet of living space⁹. City of Lonoke flood rules require a local floodplain development permit before development in a mapped Special Flood Hazard Area²⁵.

Before building a residence with an onsite wastewater system in Lonoke County, submit the permit application and detailed plans to the Arkansas Department of Health or its Authorized Agent for approval⁷. Construction, alteration, repair or extension requires a septic construction permit, and operation requires inspection, approval and a septic operation permit⁷. The installer must notify the Authorized Agent when the system is ready for inspection and send the required documentation to the local health unit within 5 days; the system may not be used until the Authorized Agent issues the Permit for Operation⁷. These septic permits apply whether the parcel is in the unincorporated county or inside Lonoke or Cabot⁷. The state Onsite Wastewater Program works with an Environmental Health Specialist in the county health department²². Soils matter here: only 3.6% of Lonoke County's land is free of severe limitations for a conventional septic drain field, so budget for a site evaluation and the possibility of an alternative system¹⁹. If a sanitary sewer is available within 300 feet of where the sewer exits the building and connection does not cross another person's property, the premises must connect to the sewer rather than use an onsite system⁷. Arkansas does not approve holding tanks for full-time or part-time residences⁷. We could not confirm a separate owner-facing permit step for an ordinary private domestic well; ask the Arkansas Department of Health before drilling²⁶.

We could not confirm whether unincorporated Lonoke County allows long-term RV, manufactured-home or tiny-home occupancy on an individual private parcel; ask the County Judge's Office before buying or placing a unit¹. Inside the City of Lonoke, city zoning approval applies and a single-family dwelling must contain at least 500 square feet of living space, so the city rule can exclude smaller tiny houses even though it does not answer how a unit on wheels is classified^3,9. Arkansas park rules apply when three or more paid spaces are provided: qualifying RV and tiny-home parks need Department of Health approval before construction or alteration, and RVs cannot be permanently connected¹³. Qualifying manufactured-home parks also face state placement and separation rules¹³. These park rules do not answer occupancy on a single private parcel.

1. Determine whether the parcel is unincorporated or inside a city, because Lonoke, Cabot and Ward administer their own zoning and building permits within city limits^6,10,11. Ask the County Judge's Office which zoning, subdivision or flood rules apply to an unincorporated parcel¹.
2. Find out whether an available sanitary sewer is within 300 feet of the building's sewer-exit point and can be reached without crossing another person's property; if so, connection is required⁷.
3. If sewer connection is not required, order a septic site evaluation early because only 3.6% of county soils lack severe limits for a conventional drain field¹⁹.
4. Apply for septic construction and operation permits through the Arkansas Department of Health or its Authorized Agent⁷. Do not plan on a residential holding tank, which Arkansas prohibits for full-time and part-time residences⁷.
5. If acting as your own contractor, confirm the licensing exemption: it covers an owner building their own residence or acting as their own home-improvement contractor on their own property, but the owner-builder status does not answer separate permit or code obligations^2,12.
6. For state-highway access, send the district engineer the work description, location, contact details, drawings and any required bond; do not begin right-of-way work before permit issuance^15,16. A single noncommercial driveway normally has no bond, though multiple driveways may require one¹⁷.
7. Build to Arkansas's statewide code even where no local inspection occurs^2,8. Inside the City of Lonoke, apply for the city building permit through the Administration Office; city officials inspect as needed for code compliance, and occupancy or a change in use requires a certificate of occupancy and compliance^3,9.

Water and soils go together here: Lonoke County gets about 51.6 inches of rain a year with only 7.6% of years in severe drought, but just 3.6% of soils are free of severe septic limitations, so a well-planned septic design deserves real budget even in a relatively wet county¹⁹. The land is flat and largely open — 99.5% sits at 15% slope or less, with 28.5% wooded — good for building sites with some natural cover¹⁹. Confirm whether the parcel is unincorporated or within Lonoke, Cabot, Ward or another municipality because local zoning varies and the cited city zoning rules stop at their respective corporate limits⁶. Check FEMA flood maps and ask the County Judge's Office whether any flood-damage-prevention ordinance reaches your specific unincorporated parcel¹. Typical property tax runs low here, about 0.6% effectively, with a median bill near $1,178 a year, against a typical home value around $231,818¹⁹.
