Barndominium Builders in Faulkner County, AR

Faulkner County has 133,979 people on 647 square miles, grew 8.5% in five years, and still has 47.2% of its land in farms with a median farm of 65 acres — the best-balanced combination of metro demand and buyable acreage anywhere in the Little Rock–North Little Rock–Conway area. It is also a county whose own codified Code of Ordinances contains a chapter headed Urban / Rural Development whose building article reads, in full, "Reserved." What governs a barndominium on unincorporated ground here is not a building department, because there isn't one: it is the ground itself — sandstone within a foot and a half of the surface across great stretches of it — plus a floodplain permit, a 911 address, and the state licences that follow the trades onto the site.

Faulkner County sits in the middle of our regular central Arkansas working area, and the run through Conway, Greenbrier, Vilonia, Wooster, Mayflower, Enola and Guy is an ordinary week rather than a special trip, so walking a piece of unincorporated ground, looking at how a driveway would meet a county road, and calling in at the OEM counter on Acklin Gap Road are all routine here.

Building conditions in Faulkner County

The State's code reaches every parcel in Arkansas, including rural and unincorporated land. What is not everywhere is the office that checks it: a city or county is authorised to set up a building department, not required to, and a great deal of rural Arkansas never has. So the first question on any parcel is not what the code says — that part travels — but whether anyone here issues a permit, inspects the work, or publishes the design criteria your drawings still have to satisfy. Where nobody does, the obligation does not go away. It just moves to the appraiser, the insurer, your lender and whoever buys the place from you.

The county's codified building article reads, in full, "Reserved"
Faulkner County adopted a Code of Ordinances by quorum court ordinance in September 2021 — fourteen chapters, prepared by the Association of Arkansas Counties Risk Management Fund and hosted in PDF form by Municode, online content updated 7 December 2021. Chapter 13 is headed Urban / Rural Development and has five articles: Building, Planning / Zoning, Economic Development, Housing, and Watercourse, Drainage, Irrigation, Flood Control Services. Article I, BUILDING, consists of one heading, "Section", and one word, "Reserved." Article II, PLANNING / ZONING, reprints the text of A.C.A. § 14-17-209(a) — the state statute that would let a county planning board prepare a zoning ordinance for the unincorporated area — and A.C.A. § 14-17-210, and then stops at a bare "Section" heading with no county ordinance beneath it. Economic Development, Housing and the flood-control article are each marked Reserved as well. The adopting ordinance repealed all prior ordinances on the subjects the code addresses unless they were re-ordained in it. The county has the statutory machinery printed in its own book and has never switched it on.

The county says it issues no certificate of occupancy — and the address letter is the real gate
Faulkner County OEM's 911 addressing page states that OEM assigns 911 addresses throughout the county except within the Conway city limits, and adds: "Please note that the county does not issue Certificates of Occupancy." The same page sets out what does gate a finished house on rural ground here. Utility providers must receive an official address verification letter from OEM before activating services for new residents. A property inside a Special Flood Hazard Area must obtain a floodplain development permit before an address will be assigned at all. The address is requested through the county's OneMap form, which asks for the structure type, the name of the signed road the property is accessed from, the driveway length in feet, and two pinned locations — one for the structure and one for the road access — with most requests finalised within three business days and a site visit if the information will not resolve. On unincorporated land in this county the sequence that decides when you can turn the power on is floodplain permit, then 911 address, then address verification letter — not plan review, inspection and CO.

The two most extensive soils in the county both end in sandstone, one of them at 17 inches
SSURGO maps the Faulkner County survey area, AR045, at data version September 2025. Its most extensive major soils are Linker at about 89,300 acres, Mountainburg at about 85,800, Leadvale at about 74,600, Taft at about 42,000 and Enders at about 27,400. Linker and Mountainburg are both Hapludults over sandstone, and the depth is the whole story: SSURGO puts the lithic bedrock restriction under Linker at an average of about 90 centimetres, roughly three feet, and under Mountainburg at about 43 centimetres — roughly 17 inches. Mountainburg's R horizon starts at 41 centimetres in the representative profile. Leadvale and Taft carry a fragipan at 64 and 61 centimetres, about two feet down, and a fragipan is what perches water above itself through an Arkansas winter. Enders is the clay one: its Bt horizons run 47 to 50 percent clay with a saturated hydraulic conductivity of 0.21 micrometres per second and paralithic rock at 139 centimetres. Across the whole survey area, 52.7 percent has a bedrock restriction within 152 centimetres and 31.5 percent carries a fragipan. Trenching, not bearing capacity, is the budget line here, and it is the septic field that pays it.

The state banned new disposal wells across four counties because of the swarm under this one
Arkansas Oil and Gas Commission Order No. 180A-2-2011-07, issued after a public hearing in El Dorado on 26 July 2011 and effective from and after 2 August 2011, placed an immediate moratorium on any new or additional Class II commercial disposal well or Class II disposal well permits across a defined area of Cleburne, Conway, Faulkner and Van Buren counties. The Commission's findings state that seismic activity in the moratorium area "has revealed a previously unknown or unmapped fault system", that the fault "may be capable of producing additional earthquakes of similar or greater magnitude as have already occurred", and that the system, highlighted by activity associated with the Guy-Greenbrier Earthquake Swarm, is a roughly N30°E trending fault displacing Lower Ordovician through Precambrian strata. Four disposal wells stood inside the area at the time; the operators of three agreed to cease disposal immediately and permanently and to plug them by 30 September 2011. This is a dated, primary, Faulkner-County-specific regulatory event, and it has nothing to do with the New Madrid zone 130 miles to the east.

Also worth knowing before you build in Faulkner County

The floodplain permit is the county's only development permit, and it wants two feet of freeboard
The Flood Damage Prevention Code for Faulkner County, dated 19 March 2019 and adopted as Ordinance 19-06 after FEMA revised ten flood insurance rate map panels along the Cadron watershed, is the closest thing the county has to a building ordinance. It appoints the County Judge or a designee as Floodplain Administrator and makes the Quorum Court the Appeal Board. In Zone AE the top surface of the lowest floor of a new residential structure must be two feet or more above the published base flood elevation, documented on an Elevation Certificate completed by an engineer, surveyor or architect licensed in Arkansas. Construction of basement foundations anywhere in a Special Flood Hazard Area is prohibited. Article 3 also states that "all mixed-use structures are subject to the more stringent requirements of residential structures" — which is exactly what a dwelling-and-shop building is. The permit expires if no work is commenced within six months, and the development may not be used or occupied until a Certificate of Compliance is issued after inspection. The county's own page says a floodplain permit must be obtained before any development begins and that this applies countywide; the application packet limits the requirement to Special Flood Hazard Areas. Either way, OEM is the office that decides, and it does so for everywhere outside Conway, Mayflower, Wooster, Vilonia and Greenbrier.

A driveway onto a county road needs a permit from the county judge — and it is free
Chapter 12 of the Faulkner County Code, § 1200.04, states that no road, driveway, or other entrance or exit of any nature or form shall be made into any county road without first having obtained a permit from the county judge, and that failure to obtain or comply with one is a continuing misdemeanour with each day a separate offence, punishable by a fine of up to $250.00 a day. The same section then does something unusual: it directs that the county judge shall charge a reasonable inspection fee for each permit requested, "except a permit requested for private, one-family driveway for which no inspection fee shall be charged." So the one county permit a single-family barndominium owner is most likely to need is the one the code specifically exempts from a fee. The county publishes the Road Improvement Permit Request form and a Road Improvement Guide alongside its road ordinances 84-13, 07-06, 07-10, 07-13, 07-15, 08-11 and 08-20.

Build your own road and the county publishes the spec: 24 feet wide, six inches of Class 7
Faulkner County's Road Improvement Guide sets out what a private road must be before the county judge will court-order it into the county maintenance system, and it is a real specification. A minimum of six inches of Class 7 gravel compacted on the road bed. A road bed at least 24 feet wide with a driving surface at least 20 feet wide. A 50-foot right-of-way measured from the centre of the road. A minimum 40-foot entrance onto any other road. A 50-foot turning radius at the end of a dead end. Drainage in concrete or galvanised tile, 15 inches in diameter. Sloped ditches on both sides. The guide also records the step most rural buyers do not expect: anyone subdividing land is required to file a subdivision plat with the county judge showing the right-of-way to be dedicated and the location of water lines and fire hydrants, and the plat must be approved by the county judge before road construction starts. After construction the road is inspected, sits one calendar year to test its integrity, and is inspected again before the judge may take it in. Until then it is a private road and its maintenance is the owners' problem.

40,000 earthquakes since 1982, none above magnitude 4.5, and no reported structural damage
The county's own 2021 Hazard Mitigation Plan, covering unincorporated Faulkner County and eleven cities, sets out the seismic history in its own words. On 12 January 1982 an earthquake of magnitude 1.2 was recorded near Enola; since then more than 40,000 earthquakes have been recorded in the Enola area, most of them microquakes. "Earthquakes in the Enola Swarm area have not exceeded a magnitude of 4.5. No structural damage has been reported." Roughly 2,500 events were recorded in the Enola area in 2001 alone by a portable monitoring network. A second swarm began in late 2010 around Guy and Greenbrier, and the plan records its most powerful event as a magnitude 4.7 on the night of 27 February 2011. The plan's table of magnitude 4.0-and-above events in the county between 1965 and 2017 lists five: 4.7 in February 2011, 4.7 in January 1982 with a felt area of about 75,000 square kilometres, 4.4 in 2001 with a felt area of about 43,500 square kilometres, 4.3 in January 1982 and 4.1 in February 1982. That is a genuine local hazard record and it is also the reason a design conversation here should start with an engineer rather than a map.

Lake Conway has been drained since September 2023 and will stay dry for up to five years
Lake Conway was built in 1948 and was at the time the largest lake ever constructed by a state wildlife agency. The Arkansas Game and Fish Commission opened the first gate at the dam on 1 September 2023 and all operational gates on 15 November 2023 to draw the 6,700-acre lake down completely for a renovation that replaces the obsolete gate system with a modern spillway, and AGFC's own project page states that the lake must remain dry for up to five years. Contractors began removing old infrastructure at the dam in October 2025 and by August 2026 the bridge had been set over the auxiliary structure. Two details matter to anyone buying near it. Silt has taken as much as three feet of depth out of parts of the lake, and drying and compaction are expected to recover as much as a foot and a half. And AGFC records that in the 2019 flood the Arkansas River "flowed backward over the gates of the current spillway" — which is the clearest single statement of how the Mayflower end of Faulkner County drains. The new spillway is also intended to end the annual winter drawdown the lake has always had.

This is hay and cattle country, not row crop: 70,311 acres of pasture against 4,893 irrigated
The 2022 Census of Agriculture records 1,130 farms in Faulkner County on 195,761 acres, 47.2 percent of the county, averaging 173 acres with a median of 65. The use split is the thing to read: 70,311 acres of pastureland against 61,960 acres of cropland and 51,776 acres of woodland, with only 4,893 acres irrigated — two percent of the land in farms. The top crop by acreage is forage, hay and haylage of all kinds, at 37,261 acres; soybeans account for 4,828 acres and rice 2,592. Fifty-six percent of the county's $33.8 million of product sales is livestock and poultry, with cattle and calves alone at $16.4 million. That is a completely different landscape from the flat irrigated Delta counties an hour east, and it is why the ownership pattern here is fine-grained: 98 operations are 1 to 9 acres and 388 are 10 to 49, so 486 of the 1,130 farms — 43 percent — are under fifty acres, and 390 of them sold less than $2,500 of product in 2022. Those are homesteads with a few head on them, and they are the parcels that come to market.

About 61,000 acres of the county are steeper than the septic rule's variance line
Faulkner County is where the Arkansas River Valley meets the southern edge of the Ozarks and the Ouachita front, and the terrain shows it. A SSURGO query of survey area AR045 returns roughly 60,700 acres — about one acre in seven of the 425,000 acres mapped — with a representative slope steeper than 12 percent, and roughly 113,300 acres, better than a quarter of the county, steeper than 8 percent. Twelve percent is the statewide line in the Arkansas onsite wastewater rules above which a capping-fill system needs a variance, so on a good deal of the higher ground north and west of Greenbrier and Guy the slope decides the septic design before the soil pit does. About 30,400 acres are mapped as hydric, which is the other end of the same problem. Between shallow sandstone on the ridges, a fragipan on the benches and hydric ground in the bottoms, the parcel that works here is usually the one with a bench of Linker or Leadvale wide enough for a house pad and two absorption areas.

Two Faulkner County towns cannot get NFIP flood insurance at all
FEMA's community status data lists eleven Faulkner County communities. Unincorporated Faulkner County is community 050431, in the regular programme since 27 September 1991, on a currently effective map dated 21 March 2019 — the same date as Conway and Wooster, and the map revision that prompted the county's 2019 Flood Damage Prevention Code. Enola's map carries the note NSFHA, meaning no special flood hazard area is mapped there at all. But the Town of Twin Groves, community 050141, was sanctioned on 19 December 2007 and the Town of Mount Vernon, community 050570, on 19 December 2006, and neither is participating in the National Flood Insurance Program. In a non-participating community an NFIP policy cannot be written whatever the flood map shows, which is a materially different proposition from a high premium and is worth knowing before a lender asks. Damascus, Greenbrier, Guy, Holland, Mayflower and Vilonia all participate.

Conway's one-mile planning ring over the county ended in 2025, and the city wrote the repeal itself
Until 2025, Arkansas cities of 8,000 or more administered planning ordinances a mile or more out into the county under A.C.A. § 14-56-413. Act 314 of 2025 repealed that section outright. Faulkner County's own press release on a different 2025 act names 5 August 2025 as that session's effective date for non-emergency legislation. The City of Conway then put the consequence in writing: the ordinance on its 28 October 2025 City Council agenda is titled "AN ORDINANCE TO REPEAL THE CITY OF CONWAY'S PLANNING OR TERRITORIAL JURISDICTION OUTSIDE OF CITY LIMITS IN COMPLIANCE WITH ACT 314 OF 2025", recites that municipalities over 8,000 in population were authorised to exercise extraterritorial jurisdiction up to one mile beyond their corporate limits, repeals the territorial-jurisdiction parts of zoning code section 308.2 and of Subdivision Regulations Article 1 section 3, Article 5 section 9 and Article 8 section 5, and provides that the city "shall, in keeping with State Law, Act 314 of 2025 surrender any oversight regarding the subdivision development outside of the City of Conway incorporated limits." The mile-wide belt around Conway, and the equivalent belts around Greenbrier, Vilonia and Mayflower, now answer to Faulkner County — which, as its own code shows, has adopted nothing to answer with. Any Faulkner County land-use handout written before August 2025 is out of date on this point.

Inside Vilonia a new house is $300, and the city's own sheet sets the slab
Vilonia is the clearest published contrast to unincorporated ground in this county. Its Code Enforcement Department charges $300.00 for a new residence, $100.00 for a storage or garage building, and $200.00 for a manufactured home, payable when the application is submitted, and no work is performed until the permit is issued. Copies of all electrical, plumbing and HVAC licences must be submitted with the application and are kept on file at city hall. A separate plumbing permit comes from Vilonia Waterworks and a sewer connection permit from Vilonia Sewer, and the water and sewer connection points must be shown on the plat. The city's Information Regarding Building Permits and Inspections sheet, dated 5 January 2022, sets concrete floor slabs at a minimum four-inch thickness with an approved vapour barrier and 6x6 10-10 wire mesh, footing steel at a minimum of two #4 bars — four for monolithic slabs — and fill at a minimum 95 percent compaction, and requires a builder's sign with licence number, a portable toilet, a trash container, erosion control where the lot slopes, and a plot plan at the first inspection. The same sheet lists the 2012 Arkansas Fire Prevention Code, the 2015 IBC and the 2006 Arkansas Plumbing Code; the state's 2021 Arkansas Fire Prevention Code took effect on 1 January 2023, so check the current adopted list at city hall before drawing to that sheet.

The school safe rooms open themselves, and the county keeps a register of private shelters
Faulkner County has one of the densest public storm-shelter networks in Arkansas, built after the tornado years. Fourteen Conway Public Schools buildings hold public safe rooms wired to the City of Conway's Severe Weather Alert System: when a Tornado Warning is issued the doors open automatically for public access, and they are checked weekly through storm season. Vilonia's school shelters open automatically the same way. Greenbrier, Wooster and Springhill schools open with a sign-in, Mayflower's are manually unlocked, and the county operates its own shelters behind the OEM building at 57 Acklin Gap Road in Conway and at 336 Sawmill Road in Holland, open during Severe Thunderstorm or Tornado Warnings, with all three deadbolts to be locked from the inside. The county also runs a storm shelter registration form that records the shelter's location and the number of day and night occupants in the local emergency management database so responders can find it. On rural acreage where nothing else is inspected, registering a shelter is one of the few things the county actively wants to know about a new build.

The county applies Arkansas's earthquake law to its bridges — and to nothing you would live in
Chapter 12 of the Faulkner County Code sets minimum bridge design standards for replacement and new bridges on county roads: HS-20 design loading, widths from 24 to 40 feet by traffic count and terrain, railing required on all bridges, and design speeds tabulated separately for flat, rolling and mountainous terrain — a county that needs three terrain columns. The section then provides that upgrading, construction and erection of bridges on the county road system "shall be subject to and meet the provisions as set forth in A.C.A. § 12-80-101 through § 12-80-106 (Act 1100 of 1991), requiring earthquake resistant design for public structures." That single sentence is the cleanest illustration in Arkansas of where the state's seismic law actually reaches. Faulkner County requires earthquake-resistant design of a county bridge over a creek. It requires nothing of the house beside it, because the statute is written for public structures and the county has adopted no residential building code. If you want seismic detailing in a wide-span pole barn on this ground, it comes from your engineer and your specification, not from a counter.

Below the slab

The expensive surprises are in the ground, not the building

What moves an Arkansas budget is usually below grade, and the state hands you a different problem depending on where you stand. In the Delta the issue is shrink-swell clay that moves with the season, and it is the reason a wide, light building with a big slab and a big door opening is the shape most at risk. Along the Fall Line there is a second, separate clay belt with nothing to do with the Delta at all. Up in the Ozarks the question inverts: what matters is not what the slab sits in but what is under it, because that limestone is full of solution cavities and the collapses arrive with no prior indication at the surface. And on Crowley's Ridge, where Jonesboro and Paragould sit, it is fine wind-blown loess that stands up in a vertical cut and then erodes out from under whatever you put on it. The same ground decides your wastewater system, which is the gate that most often moves a rural build's schedule — and it is soils that decide it, not the size of the house. So the site work, the foundation and the wastewater get resolved together rather than one at a time. We price the dirt before we price the building.

What a build looks like

Three stages every Faulkner County project passes through, from a raw parcel to a finished home. Site work first, because that is where the budget is decided.

Where we build around Faulkner County

Faulkner County and the rural land around it. The buildable acreage for a project this size usually sits outside the city limits, which is frequently what changes who issues your permit.

The Faulkner County service area, including the rural acreage outside the built-up edge, which is where the parcels big enough for a build like this usually sit. The map marks the territory we build in. It is not a branch location, and there is no office at this pin.

Nearby areas we build in

Others we cover nearby. One may be a county, another a city inside it — and since March 2025 the soft edge between them is gone, because the cities' extraterritorial jurisdiction was abolished outright and that land reverted to the counties. So the office that issues the permit, the fees it charges, the zoning and whether anyone publishes design criteria at all can differ from one card to the next, and the boundary that decides it may have moved recently.

Building in Faulkner County: common questions

9 questions we get asked most often about building in Faulkner County. If yours is not on the list, ask it directly.

Does Faulkner County issue a building permit for a barndominium on unincorporated land?
No. There is no building department in Faulkner County government, no county building permit, no county plan review, no county inspection sequence and no county certificate of occupancy. The county's own published department directory lists the county judge, county clerk, circuit clerk, civil attorney, assessor, collector, treasurer, coroner, sheriff, prosecuting attorney, public defender, roads, emergency squad, veteran services, the library system and the Office of Emergency Management, and not one of them is a building or planning office. The county judge's own staff page lists a county administrator, an office manager, administrative assistants, human resources, IT and building maintenance. The reason is structural rather than accidental. Arkansas makes county zoning a two-step opt-in: the county judge, with the approval of a majority of the quorum court, may create a county planning board, and only after that may the court adopt a zoning ordinance, which the statute says is observed through denial of the issuance of building permits. No board, no ordinance, no permit, and nobody to deny one. Faulkner County has taken neither step. Its published list of boards and commissions contains a 911 advisory board, a depository board, election commissioners, an equalization board, a wastewater utility board, a law library board, a library board, a museum commission and a public facilities board, and no planning board. Its own codified Code of Ordinances has a chapter for urban and rural development whose building article says only "Reserved." And the county states the practical consequence itself on its 911 addressing page: the county does not issue Certificates of Occupancy.
If the county does not permit, what do I actually have to get before I can build here?
Four things, and none of them is a building permit. First, an onsite wastewater permit from the Arkansas Department of Health, which on most rural Faulkner County acreage is the only construction permit a landowner ever encounters. It is a statewide permit under a statewide rule, the application has to be approved before construction of a building or residence, and Part I must be completed by a Designated Representative you hire — often a master plumber or a land surveyor, since Arkansas builds that role onto another licence. Two soil pits four feet deep, one in the primary and one in the secondary absorption area, left open for the county's Authorized Agent. Second, if the property touches a Special Flood Hazard Area, a floodplain development permit from Faulkner County OEM, and OEM will not assign a 911 address until that permit is issued. Third, a 911 address from OEM, requested through the county's OneMap form, which wants the structure type, the access road name, the driveway length in feet and pinned locations for both the structure and the road access; utility providers must receive an official address verification letter from OEM before they will activate service for a new resident. Fourth, if the build needs a new driveway or road cut onto a county road, a permit from the county judge — required by the county's road code, and specifically exempt from an inspection fee for a private one-family driveway. Everything else that binds is state law: the plumbing code applies statewide by statute, and electricians, plumbers and HVACR mechanics are licensed by the State whether there is a permit counter or not.
Conway, Greenbrier, Vilonia and Mayflower used to regulate land outside their limits. What happened?
Act 314 of 2025 abolished municipal extraterritorial jurisdiction in Arkansas altogether. Until then, A.C.A. § 14-56-413 let a city of 8,000 or more administer and enforce planning ordinances one, two or three miles out into the county depending on its population, and the exurban belt around Conway was exactly the kind of ground a barndominium buyer wants. The act repealed § 14-56-413 outright, repealed the provision that let a municipality exercise subdivision jurisdiction in adjoining unincorporated areas, and repealed the provision that let a city extend electrical permit and inspection jurisdiction into the same ring by city–county agreement. Faulkner County's own press release on a separate 2025 act names 5 August 2025 as the effective date for that session's non-emergency legislation. Conway then acted on it in the open: the ordinance placed before its City Council on 28 October 2025 is headed as a repeal of the city's planning or territorial jurisdiction outside city limits in compliance with Act 314, recites that cities over 8,000 were authorised to reach up to a mile beyond their corporate limits, strikes the territorial-jurisdiction language from the city's zoning code and three articles of its subdivision regulations, and provides that Conway surrenders any oversight regarding subdivision development outside its incorporated limits. What that means in practice is that the mile-wide belt around Conway, and the equivalent belts around Greenbrier, Vilonia and Mayflower, reverted to the county — and the county has adopted no zoning, no subdivision control and no building code. Any handout or blog post about building near Conway that predates August 2025 is wrong about this.
What will the ground do to my foundation here?
Faulkner County sits where the Arkansas River Valley runs into the southern Ozark and Ouachita fronts, and the soils are a straightforward reflection of that. The two most extensive soils in the county are Linker and Mountainburg, at roughly 89,300 and 85,800 acres, and both are sandy loams over sandstone. SSURGO puts the lithic bedrock restriction under Linker at an average of about 90 centimetres, near three feet, and under Mountainburg at about 43 centimetres — roughly 17 inches, with the rock horizon starting at 41 centimetres in the representative profile. That is shallow enough to matter to a footing trench, a plumbing run and a septic field all at once, and 52.7 percent of the survey area carries a bedrock restriction within 152 centimetres. The next two soils, Leadvale at about 74,600 acres and Taft at about 42,000, carry a fragipan at 64 and 61 centimetres — a dense pan that perches water above itself through winter and spring, and which the state's onsite wastewater rule treats as a restrictive soil layer. Enders, about 27,400 acres, is the clay: Bt horizons of 47 to 50 percent clay with saturated hydraulic conductivity of 0.21 micrometres per second. Down in the Arkansas River backswamp near Mayflower and Lake Conway there is Perry, a Chromic Epiaquert whose subsoil runs 70 percent clay with a linear extensibility of 15.7 — the shrink-swell problem, on a small footprint but a real one. Slope compounds all of it: about 60,700 acres of the county are steeper than 12 percent and about 113,300 acres steeper than 8 percent. A pole barn on a slab is a wide, light, stiff building, and on this county's ground the whole design argument is about drainage, cut-and-fill and how far down the rock is, not about bearing capacity.
This county had an earthquake swarm. Do I have to design for it?
You have to think about it, and you should not take a number off a map. The record is real and it is local. The county's 2021 Hazard Mitigation Plan states that an earthquake of magnitude 1.2 was recorded near Enola on 12 January 1982 and that more than 40,000 earthquakes have been recorded in the Enola area since, mostly microquakes, with the plan adding that events in the Enola swarm area have not exceeded magnitude 4.5 and that no structural damage has been reported. A second swarm began around Guy and Greenbrier in late 2010, and its largest event was magnitude 4.7 on the night of 27 February 2011. The state's response was regulatory: Arkansas Oil and Gas Commission Order 180A-2-2011-07, effective 2 August 2011, banned new Class II disposal well permits across an area of Cleburne, Conway, Faulkner and Van Buren counties, finding that the seismicity had revealed a previously unknown fault system trending about N30°E, and three of the four wells then inside the area were plugged by 30 September 2011. What none of that gives you is a design figure. No Faulkner County jurisdiction publishes a seismic design category. Arkansas's own earthquake law, A.C.A. §§ 12-80-101 to 12-80-106, reaches public structures — the county applies it to county bridges in its own road code — and not to a private dwelling. Computed from the USGS design-maps service on 8 September 2026 at Risk Category II and Site Class D-default, the county's Census internal point returns S_DS 0.519 g, which is Category D-sub-zero under the residential code's table, while Greenbrier returns 0.487 g and Mayflower 0.450 g, both Category C. The boundary is 0.500 g. That is a computation, not a published requirement, and the fact that one county straddles it is precisely why the answer for a wide-span building here comes from an engineer working from a real site class.
What does it cost to build inside a Faulkner County town instead, and how is that different?
It is a different regime, and the fees are published. The City of Vilonia charges $300.00 for a new residence, $100.00 for a storage or garage building and $200.00 for a manufactured home, payable when the application is submitted, with no work performed until the permit is issued; commercial permits run $500.00 plus $0.50 per $1,000 of construction cost with a $1,000.00 cap, plus a $100.00 site plan review and $0.02 per square foot. Copies of the electrical, plumbing and HVAC licences go on file at city hall with the application, a separate plumbing permit comes from Vilonia Waterworks and a sewer connection permit from Vilonia Sewer, and the connection points must be shown on the plat. The city's own information sheet sets minimum construction details a county buyer never sees: four-inch slabs with an approved vapour barrier and 6x6 10-10 wire mesh, footing steel of at least two #4 bars and four for monolithic slabs, engineered fill compacted to at least 95 percent, plus a builder's sign with licence number, a portable toilet, a trash container and erosion control on site at the first inspection. Conway publishes an adopted-codes list — the 2021 Arkansas Fire Prevention Code, the 2020 National Electrical Code, the 2018 Arkansas Plumbing and Fuel Gas Codes, the 2021 Arkansas Mechanical Code and the 2014 Arkansas Energy Code — and no design figures with it. One caution: Vilonia's sheet is dated 5 January 2022 and names the 2012 Arkansas Fire Prevention Code, while the state's 2021 edition took effect on 1 January 2023, so confirm the current adopted list at the counter before drawing to it.
Can I actually buy a homesite-sized piece of Faulkner County, and where?
Yes, and this is one of the few metropolitan counties in Arkansas where the answer is straightforwardly yes. Faulkner County is inside the Little Rock–North Little Rock–Conway metro, grew 8.5 percent between 2020 and 2025 to 133,979 people, and still has 47.2 percent of its 647 square miles in farms. The 2022 Census of Agriculture counts 1,130 farms on 195,761 acres with a median of 65 acres and an average of 173. The size distribution is what matters: 98 operations are 1 to 9 acres and 388 are 10 to 49, so 486 farms — 43 percent of them — are already under fifty acres, and 390 of the 1,130 sold less than $2,500 of product in 2022. That is a landscape of smallholdings, not industrial blocks, and it is the opposite of the Delta counties an hour east where median farm sizes run into the hundreds of acres and there is very little for sale at homesite scale. The land use backs it up: 70,311 acres of pastureland against 61,960 of cropland, only 4,893 irrigated acres, and forage as the county's biggest crop at 37,261 acres. Where to look depends on what you want. North and west of Greenbrier, Wooster and Guy is the rolling, wooded, steeper ground — pretty, more expensive to develop, and where the shallow sandstone and the 12 percent slope line bite. East around Vilonia and Mount Vernon and north toward Enola is gentler farmed benchland. South toward Mayflower runs into the Arkansas River bottoms and Lake Conway, where the constraint is flood mapping and clay rather than rock.
Lake Conway has been drained. Does that change anything about building near it?
It changes the timeline and it tells you something permanent about how that end of the county drains. Lake Conway was built in 1948 and was at the time the largest lake ever constructed by a state wildlife agency. The Arkansas Game and Fish Commission opened the first dam gate on 1 September 2023 and all operational gates on 15 November 2023, drawing the 6,700-acre lake down completely so that its obsolete gate system could be replaced with a modern spillway, and AGFC states the lake must remain dry for up to five years. Demolition of the old dam infrastructure began in late October 2025 and by August 2026 the bridge had been set over the auxiliary structure. Three facts follow for a build. Depths will change: silt has taken as much as three feet out of parts of the lake and AGFC expects drying and compaction to recover as much as a foot and a half, so shoreline access and boathouse usability will not be what a 2020 listing photograph shows. The lake's shoreline is state-owned, structures on it are permitted, and AGFC has been demolishing abandoned boathouses and piers during the drawdown. And AGFC's own account of the 2019 flood — the Arkansas River flowed backward over the gates of the spillway — is the clearest published statement of the flood dynamic in the Mayflower corner of Faulkner County. The new spillway is also intended to end the annual winter drawdown the lake has always had, which changes the normal winter water line for anyone siting near it.
How much of a flood problem is this county, and what does it require?
Enough that the flood ordinance is effectively the county's only development regulation. Unincorporated Faulkner County has been in the National Flood Insurance Program since 27 September 1991, and its currently effective map is dated 21 March 2019 — the FEMA revision, covering ten flood insurance rate map panels along the Cadron watershed, that prompted the Quorum Court to pass an updated Flood Damage Prevention Ordinance on 19 March 2019. That code appoints the county judge or a designee as Floodplain Administrator and makes the Quorum Court the Appeal Board. For a new residential structure in Zone AE the top surface of the lowest floor must be two feet or more above the published base flood elevation, documented on an Elevation Certificate completed by an engineer, surveyor or architect licensed in Arkansas; basements are prohibited outright anywhere in a Special Flood Hazard Area; and the code states that mixed-use structures are subject to the more stringent requirements of residential structures, which is what a dwelling-and-shop building is. The permit lapses if work is not commenced within six months and the development may not be used or occupied until a Certificate of Compliance is issued after inspection. OEM administers this for everywhere outside the city limits of Conway, Mayflower, Wooster, Vilonia and Greenbrier. Two towns to check before you sign anything: the Town of Twin Groves was sanctioned in December 2007 and the Town of Mount Vernon in December 2006, and neither participates in the NFIP — which means a federal flood policy cannot be written there at all, whatever the map shows.

Building in Faulkner County?

Start with the plan. Tell us what you want to build and we will draw it, then confirm which office issues the permit for your parcel, what it will let you put there, and what wind load it has to meet. That conversation costs nothing.
