Barndominium Builders in Sampson County, NC

Sampson County holds more land in farms than any other county in North Carolina: 882 farms across 292,205 acres, 48.3 percent of the county, at a median farm size of 84 acres against a statewide median of 48. It produces 12 percent of the state's total agricultural sales — the largest share of any county — and ranks first in the United States for the market value of hogs and pigs sold and third for poultry and eggs. And it sits in no metropolitan or micropolitan statistical area at all, one of 29 North Carolina counties in that position, which means the county with the most farmland in the state is quietly dropped from any market dataset built on metro areas. If you are looking for acreage within reach of Fayetteville, Goldsboro or Wilmington, that omission is in your favour. Permitting here is unusually simple by North Carolina standards. Sampson County Inspections states that it provides building inspections and permitting for all unincorporated Sampson County and, through contractual agreements, for the towns of Autryville, Clinton, Garland, Harrells, Newton Grove, Roseboro, Salemburg and Turkey — one office, whole county. Zoning is the part that splits: inside a town or its extraterritorial jurisdiction the town gives the zoning approval, and the county's own permitting guide lists the phone numbers. On the design numbers, Table R301.2(4) of the 2018 NC Residential Code names Sampson County at 130 mph ultimate design wind speed, flat, with no road split, and the county is absent from the Seismic Design Category C list. The two things most likely to decide a specific parcel are soil wetness, which the county's own Land Use Plan calls the major limitation to most land uses, and the accessory-structure rule that decides whether the shop can go up before the house.

Building conditions in Sampson County

The building code does not change at a county line here. Under § 143-138(e) the North Carolina State Building Code applies throughout the state, and a city or county may adopt only a fire prevention code and floodplain regulations of its own — there is no general local amendment power, so there are no county amendments to look up. The edition in force is still the 2018 NC Residential Code, effective 1 January 2019; the 2024 edition has been delayed three times and carries no effective date at all. What genuinely differs is who issues the permit and inspects the work, what that office charges, how the parcel is zoned, what the local floodplain ordinance requires of the foundation — and two design numbers the code publishes county by county, the ultimate design wind speed and the seismic design category. The rest of Table R301.2 is set once for everyone: a flat 20 psf roof live load, a 12-inch frost line, Moderate weathering, and termite protection required everywhere in the state with no exemption. There is no ground snow load column in the residential code at all.

First in North Carolina for farmland — and in no metro area at all
The 2022 Census of Agriculture puts Sampson County first of North Carolina's 100 counties for land in farms: 882 farms across 292,205 acres, 48.3 percent of the county, at a median farm size of 84 acres. The statewide median farm is 48 acres and 26.1 percent of North Carolina is in farms, so Sampson runs roughly double the state on both counts. It is also first in the state for total market value of agricultural products sold at $2,193,852,000 — 12 percent of North Carolina's entire agricultural sales — and 14th in the United States. And it appears in no core based statistical area whatever, one of 29 North Carolina counties in none, so a market map drawn from metro areas simply omits the county with the most farmland in the state. Population was 61,504 in 2025, up 4.2 percent since 2020, across 946 square miles at 65 people per square mile. Cropland is 200,922 acres and woodland 53,282; 265 farms are between 10 and 49 acres and 285 between 50 and 179 — the band a barndominium buyer actually shops in.

One inspections office covers the whole county, towns included
Sampson County Inspections states that it provides building inspections and permitting services for all unincorporated areas of Sampson County and, through contractual agreements, provides building inspection services for the towns of Autryville, Clinton, Garland, Harrells, Newton Grove, Roseboro, Salemburg and Turkey. That is unusual and it is worth knowing, because in much of North Carolina the answer to "who inspects this?" turns on an invisible city line — several of the state's larger counties inspect only the unincorporated area and leave every municipality to run its own department, so two parcels a mile apart go to different offices under different fee schedules. Here the building, plumbing, mechanical and electrical permits all come from one desk at 335 County Complex Road in Clinton on one schedule. What does not consolidate is zoning: the county's permitting guide sends a resident of any incorporated town to that town's own zoning office first, and lists nine phone numbers to call.

The shop can go up before the house — on five acres in RA
Sampson County's Residential Accessory Structure Site Plan Requirements answer a question every barndominium buyer asks and almost no county page addresses: "Accessory structures must be incidental to the principal structure and will not be permitted unless a principal structure exist or the parcel is located in the RA zoning district and is 5 acres or more in size." So on a Residential Agricultural parcel of five acres or more you can put the shop up first and live elsewhere while the house side gets built; below five acres, or in another district, the house has to exist first. The same document notes that garages, carports, pools and storage sheds are accessory structures, that a manufactured home or an RV never is, and that fences, play sets and planting boxes are not regulated at all. The RA district's own numbers matter to the shop too: the maximum building height is 40 feet, with 35-foot front, 10-foot side, 20-foot street-side and 25-foot rear setbacks, and a minimum lot of 30,000 square feet where there is no public water or sewer.

$0.30 a square foot on heated and unheated alike, and three different trade bases
Sampson County's current fee schedule for fiscal year 2026-2027 prices one- and two-family dwellings four ways at once: the building permit at $0.30 per square foot, electrical at $1.00 per amp of main electrical service, plumbing at $16.00 per fixture with an $80.00 minimum, and mechanical at $0.15 per square foot. The county's own permitting guide then settles the question that decides what a shop bay costs: "Permit fees vary depending on the total square footage (heated and unheated) of your project." That puts Sampson on the gross-area side of a split that runs right through this state — some counties charge on heated area only, so an unheated shop adds nothing; here it is inside the base. There is no North Carolina permit fee and no North Carolina fee basis; there are one hundred county answers. Two more lines are worth knowing before the first load of gravel arrives: plan review is listed for commercial work only, and work started before securing a permit draws a double fee on the first offence, double plus $100 on the second and double plus $300 on the third.

First in the United States for hogs — and the setback protects the farm, not the house
USDA's 2022 Census of Agriculture ranks Sampson County first in North Carolina and first in the United States for the market value of hogs and pigs sold, at $966,059,000, and first in the state and third in the nation for poultry and eggs at $948,619,000. The December 2022 inventory was 1,854,202 hogs and pigs, 18,230,713 broilers and other meat-type chickens and 3,290,350 turkeys. G.S. 106-803 sets the separation distances — and reads in the direction most buyers get backwards. A swine house or lagoon must be located at least 1,500 feet from any occupied residence, 2,500 feet from a school, hospital, church, outdoor recreational facility, park, listed historic property or licensed child care centre, 500 feet from any property boundary and 500 feet from a well supplying water for human consumption; the outer perimeter of the waste application area must be at least 75 feet from the boundary of a property with an occupied residence and from any perennial stream or river. Those distances bind the farm when it is sited or expanded. They do not stop anyone building a dwelling closer than 1,500 feet to an operation that is already there. And subsection (b) allows a swine house or lagoon closer than the statute otherwise permits where the affected property owner gives written permission recorded with the register of deeds — so the recorded chain on the parcel you are buying may already contain a signed waiver, and finding it is a title search, not a site visit.

The county's own plan names the limitation, and the rule is all-or-nothing
Sampson County's 2022 Land Use Plan describes the ground in one sentence: "Soil wetness is the major limitation to most land uses." It places the county in the Coastal Plain, gently rolling from about 20 feet above sea level in the south-east to about 210 feet in the north-west, on sedimentary soils transported by rivers and the sea, with steeper side slopes only along shallow stream valleys — and it says outright that the large bays and pocosins in the southern and north-western parts of the county drain poorly and are unsuitable for development. That lines up exactly with the parameter that fails on Inner Coastal Plain ground under 15A NCAC 18E .0504(b): a site is unsuitable where the soil wetness condition is less than 12 inches below the natural surface, or less than 18 inches where more than six inches of Group I sandy soils are present. Sandier soil raises the required depth rather than lowering it. And .0509(a) makes the classification all-or-nothing — every parameter suitable gives a suitable site, and any single unsuitable parameter makes the whole site unsuitable, with no Improvement Permit possible. This is a March question, not an August one.

Also worth knowing before you build in Sampson County

A basin divide runs through the county, and one side has a 50-foot buffer
Sampson County's Land Use Plan says most of the county drains to the Black River and Northeast Cape Fear sub-basins of the Cape Fear — Little Coharie Creek, Great Coharie Creek and Six Runs Creek form in the north and merge in the south to make the Black River, while Mingo Swamp and the South River form the western edge. But it also records that the northern tip of the county sits in the Goshen Swamp watershed, which flows east into the Upper Neuse River Basin. That divide has a legal consequence the plan itself points at when it notes that the state has enacted basin protection rules for the Neuse and Tar-Pamlico and that the Cape Fear is still being studied. North Carolina's riparian buffer programmes cover five systems — Neuse at 15A NCAC 02B .0714, Tar-Pamlico at .0734, Catawba at .0614, Randleman at .0724 and Jordan at .0267 — and the Cape Fear is not among them. So on the Cape Fear side of the divide there is no state riparian buffer at all, and on the Neuse side a mapped intermittent or perennial stream carries a 50-foot buffer in two zones, 30 feet undisturbed and 20 feet stable. Buffers run by basin and not by county line, which is why the question for a parcel here is which way the water leaves it.

What the health department charges for septic and a well
Sampson County Environmental Health's fiscal year 2026-2027 fees put a new septic system's Improvement Permit and Construction Authorization together at $400.00 for a standard system of 0 to 600 gallons per day, $500.00 for 601 to 1,250 and $550.00 for 1,251 to 3,000. An Improvement Permit alone is $200.00 and a Construction Authorization alone is $200.00 standard, $250.00 medium and $350.00 large; an existing septic system inspection is $150.00 and a system expansion $200.00. The engineered option permit is $35.00 at every size. A new well site evaluation is $350.00 with each additional well on the same property at $200.00, and the sampling menu runs $60.00 bacteriological, $60.00 nitrate and nitrite, $110.00 inorganic chemical, $110.00 pesticide, $110.00 petroleum and $150.00 for a full panel. Budget the health department separately from the inspections department: they are different offices with different schedules, and a buyer reading only the building fees will be short by several hundred dollars.

The bona fide farm exemption, and the four documents that prove it
Section 107 of the Sampson County Zoning Ordinance reproduces the state rule in the county's own text: under G.S. 160D-903, county zoning regulations may not affect property used for bona fide farm purposes, which does not limit zoning of the farm property for nonfarm purposes. What makes the county's version useful is that it lists what counts as sufficient evidence — a farm sales tax exemption certificate issued by the Department of Revenue, a property tax listing showing eligibility for the present-use value programme under G.S. 105-277.3, a copy of the owner's or operator's Schedule F from the most recent federal return, or a forest management plan. Any one of those four. The limit is the part that matters for a house, and it is the strongest single argument on this site: a dwelling is not a farm building. G.S. 143-138(b4)(1) defines a farm building as a nonresidential building, so the building-code exemption never reaches a house, and G.S. 160D-903(b) bars a county from prohibiting a dwelling on an agricultural lot over ten acres, or requiring road frontage or public water and sewer, only for a dwelling "constructed in accordance with the North Carolina State Building Code." You get the land-use right; code compliance is the price.

The expensive surprises are in the ground, not the building

What moves a North Carolina budget is usually below grade, and the thing most often got wrong is which clay to worry about. Cecil — the red Piedmont clay everyone pictures, and the state soil — is kaolinitic and low shrink-swell; it does not heave. The soil that does is Iredell, formed over diabase and gabbro, which the USDA describes as vertic, very high shrink-swell, with a perched water table a foot or two down from December through April. The tell is colour: Cecil is red and Iredell is dark grey-brown, and they sit within a few miles of each other across the central Piedmont. West of that the question stops being clay and becomes slope, rock and colluvium; east of the fall line it becomes water, and in the Tidewater it becomes organic soil that subsides irreversibly once it is drained. Then the same ground decides the septic system, and North Carolina rewrote those rules recently enough that most of what is published about them is out of date. 15A NCAC 18E replaced the old subchapter on 1 January 2024 and was amended again on 1 June 2026: the site is classified on soil morphology — the word "percolation" does not appear anywhere in it — and there is no "provisionally suitable" any more, only suitable or unsuitable, on a single failed parameter. There is no statewide minimum lot size either; the area you need is derived from the soil result and then doubled, because a site that cannot fit both the initial field and its repair area is unsuitable. And the order matters more than people expect: the county health department's Improvement Permit and Construction Authorization come first, and the building permit is available on the strength of the Construction Authorization, not before it. One more thing that catches people: disturb more than an acre and you need an approved erosion and sedimentation control plan in hand before work starts, with penalties up to $5,000 a day, and a pad plus a drive plus a drainfield plus a laydown area crosses an acre faster than it sounds. So the site work, the foundation and the drainfield 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 Sampson 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 Sampson County

Sampson County and the rural land around it. The buildable acreage for a project this size usually sits outside the town limits — which does not automatically put it under the county, because a town's zoning and building-code enforcement reach one to three miles past its limits into its extraterritorial jurisdiction. Inside the limits, in the ETJ, or in neither are three different answers to who issues your permit.

The Sampson 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. Every North Carolina municipality sits inside a county — there are no independent cities here — but that does not settle who regulates a given parcel. A town's zoning, subdivision rules and building-code enforcement extend one to three miles beyond its limits, by population, into what the statute calls its extraterritorial jurisdiction; town taxes and town elections do not follow. So the office that issues the permit, what it charges and how the land is zoned can all differ from one card to the next, and the mailing address will not tell you which case you are in.

Building in Sampson County: common questions

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

Who issues the building permit for land in Sampson County?
Sampson County Inspections, everywhere in the county. The department states that it provides building inspections and permitting services for all unincorporated areas of Sampson County and, through contractual agreements, provides building inspection services for the towns of Autryville, Clinton, Garland, Harrells, Newton Grove, Roseboro, Salemburg and Turkey. Building, plumbing, mechanical and electrical permits all come from the county complex at 335 County Complex Road in Clinton. That is genuinely simpler than most of North Carolina, where the answer often turns on an invisible city line and two parcels a mile apart go to different departments under different schedules. Zoning is where it splits, and it comes first. The county's own permitting guide lays out the sequence: zoning approval, then an elevation certificate if the property is in a designated floodplain, then the septic permit from the health department's environmental health section, then the building permit — for which you submit scaled plans showing the foundation, floor plan, wall details and all four elevations, a copy of the valid septic permit and a copy of the valid zoning approval. For zoning it directs residents of Clinton, Autryville, Faison, Garland, Harrells, Newton Grove, Roseboro, Salemburg and Turkey to their own town, and everyone outside those towns and their extraterritorial jurisdictions to Sampson County Planning & Zoning. Note the ETJ: under G.S. 160D-202 a town's zoning reaches one to three miles past its limits depending on its population, onto land that pays no town tax and votes in no town election.
Can I build the shop first and the house later in Sampson County?
On five acres or more in the Residential Agricultural district, yes — and the county says so in writing. Its Residential Accessory Structure Site Plan Requirements state that accessory structures must be incidental to the principal structure and "will not be permitted unless a principal structure exist or the parcel is located in the RA zoning district and is 5 acres or more in size." Below five acres, or in a district other than RA, the house has to be there first. The same sheet is clear about what an accessory structure is: garages, carports, pools and storage sheds are; doghouses, satellite dishes, play sets, privacy fences, yard decorations and planting boxes are not regulated by the ordinance at all; and a manufactured home or an RV is never an accessory structure under any circumstance. Two RA dimensions matter to the shop itself. The maximum building height is 40 feet, which is generous for a tall bay with a big door but is a real ceiling if you were planning a high-clearance equipment building with a mezzanine above it. And the setbacks are 35 feet front, 10 feet side, 20 feet on a side abutting a street and 25 feet rear, which is what decides how far the pad sits off the line. Every zoning permit application has to come with a site plan showing the lot's shape and dimensions, all existing and proposed buildings labelled, the setbacks to every property line, and a note giving the zoning district and its required setbacks. A hand-drawn plan is often accepted; a surveyed one prepared by a land surveyor or engineer licensed in North Carolina may be required.
What does a permit cost in Sampson County, and does the shop bay count?
Yes, the shop counts, and the county says so plainly: "Permit fees vary depending on the total square footage (heated and unheated) of your project." The fiscal year 2026-2027 schedule prices one- and two-family dwellings at $0.30 per square foot for the building permit and $0.15 per square foot for mechanical, with electrical at $1.00 per amp of main electrical service and plumbing at $16.00 per fixture on an $80.00 minimum. Reinspections are $80.00 residential. Starting work before the permit is issued costs a double fee on the first offence, double plus $100.00 on the second and double plus $300.00 on the third — an escalating ladder that not many counties publish. This is worth putting in context, because the single most useful thing to understand about building costs in this state is that there is no North Carolina permit fee and not even a North Carolina fee basis. Across the counties that publish schedules the basis takes at least six different forms — dollars per square foot, square-foot brackets, flat fees by size, a base fee plus an escalator, a multiplier on an ICC construction valuation table, and a tiered dollars-per-thousand-of-value table. And the basis matters more than the rate for a barndominium: some counties charge on heated area only, so an unheated shop bay is free, while others charge on everything under the roof. Sampson is on the second side of that line. All figures here were read from the county's own published schedule on 6 September 2026.
What wind speed and seismic category do Sampson County plans have to be drawn to?
Sampson County is one of the 49 counties North Carolina names in Table R301.2(4) of the 2018 NC Residential Code, at an ultimate design wind speed of 130 mph. It is a flat figure — no footnote, no split on a road or waterway, no elevation rule — unlike Bladen County immediately south-west, which the same table splits at 130 mph west of Highway 701 and 140 mph east, or Cumberland County to the west, split at 120 mph west of I-95 and 130 east. The 2024 edition, adopted but with no effective date at all, keeps 130 for Sampson County, so this is a county where the pending edition changes nothing. Sampson County is absent from Table R301.2(7), the list of Seismic Design Category C counties, and that table's note places every county not named in Category A or B. Sampson County is also well inland of the wind-borne debris region, which North Carolina defines as a map line — east of the Intracoastal Waterway from the South Carolina line to Beaufort Inlet, then the barrier islands north — rather than as a wind speed. Three things are the same everywhere in the state: a flat 20 psf roof live load; no ground snow load column at all, because Section R301.2.3 is deleted; and termite protection required in all of North Carolina under Section R318. That last one bites a metal building. North Carolina deleted cold-formed steel framing from the accepted methods of termite protection, so a steel barndominium still needs chemical treatment or baiting even though building in steel satisfies the requirement in the model code. Name the edition on the plan set.
What should I know about buying land near a hog or poultry operation here?
Sampson County ranks first in the United States for the market value of hogs and pigs sold and third for poultry and eggs; the December 2022 inventory was 1,854,202 hogs and pigs, 18.2 million broilers and 3.3 million turkeys, in a county of about 61,500 people. That is not scenery, it is a planning input, and three statutes decide what it means. G.S. 106-803 sets the separation distances and they bind the farm rather than you: a swine house or lagoon must be at least 1,500 feet from any occupied residence, 2,500 feet from a school, hospital, church, outdoor recreational facility, park, listed historic property or licensed child care centre, 500 feet from any property boundary and 500 feet from a well supplying water for human consumption, and the waste application area at least 75 feet from a boundary with an occupied residence and from any perennial stream. Nothing there stops you building a dwelling close to an operation that already exists — and subsection (b) lets an owner waive the distance in writing, recorded with the register of deeds, so a previous owner of your parcel may already have signed one. Check the recorded chain. G.S. 106-701 then bars a nuisance action unless the plaintiff possesses the affected property, it lies within half a mile of the source, and the action is filed within a year of the operation's establishment or a fundamental change — and a change in ownership or size, an interruption of up to three years, new technology and a change in the product produced are all expressly not fundamental changes. The one provision running the other way is G.S. 143-215.10I, which bars the Commission from permitting construction, operation or expansion of an anaerobic lagoon and sprayfield swine waste system unless the action does not increase permitted capacity or the system meets five performance standards, including substantially eliminating odour detectable beyond the parcel boundary. Existing operations are not going away; under that technology they are also not getting bigger. Go and stand on the land in warm weather with the prevailing wind behind the neighbour.
Will the land perc, and what decides it in Sampson County?
North Carolina does not decide it with a percolation test. 15A NCAC 18E evaluates a site on soil morphology — the physical description of the soil profile in a boring or pit, described to at least 48 inches or to a limiting condition — and the word "percolation" does not appear anywhere in the subchapter. The soil group sets the long-term acceptance rate, and the acceptance rate sets how much drainfield your bedroom count buys. On this ground the parameter that decides it is soil wetness. Rule .0504(b) makes a site unsuitable where the seasonal soil wetness condition is less than 12 inches below the natural surface, or less than 18 inches where more than six inches of Group I sandy soils are present — sandier ground raises the bar, because effluent moves through it faster. Sampson County's own 2022 Land Use Plan says it in plain words: "Soil wetness is the major limitation to most land uses," and it identifies the large bays and pocosins in the southern and north-western parts of the county as poorly drained and unsuitable for development. Two more rules decide acreage. Rule .0509(a) makes the classification binary — every parameter suitable gives a suitable site, and any one unsuitable parameter makes the whole site unsuitable, with .0509(d) barring an Improvement Permit on an unsuitable site. "Provisionally suitable" was repealed and appears nowhere in the current rules, though it still shows on older permits and county records. And .0508(b) makes a site unsuitable if it cannot fit both the initial system and a repair area, so the land you need is the drainfield the soil gives you, doubled, plus every setback. Sampson County Environmental Health prices a new standard system's Improvement Permit and Construction Authorization together at $400.00, and a new well site evaluation at $350.00. Rule .0509(b) leaves routes back — site modification, an interceptor drain, or advanced pretreatment — and .0510 allows a special site evaluation by a licensed professional, which is the expensive path.
Sampson County isn't in any metro area — does that make it harder to build here?
Not to build. It makes the county harder to find, which is a different problem and mostly yours to exploit. Sampson is one of 29 North Carolina counties that sit in no core based statistical area at all — no metropolitan and no micropolitan area — which means that any dataset, market map or search tool built around metro areas drops it entirely. The county with more land in farms than any other in North Carolina, and the largest agricultural sales of any county in the state, does not appear. Meanwhile Clinton is roughly an hour from Fayetteville, an hour from Goldsboro and Wilmington's northern edge, and about an hour and a quarter from Raleigh's southern reach on I-40, so the commuting geography is real even though the statistical geography ignores it. Practically, three consequences. Land comparables are thinner and appraisals on unusual buildings take longer, which is a scheduling and financing matter to raise with a lender early rather than late. There is no metro-level building activity series to reason from, so the checkable numbers are the county's own fee schedule, the census of agriculture and the code's county tables — which is what this page is built from. And the competition for parcels is lower than in the ring counties around the Triangle and Charlotte, where eight of the state's eleven fastest-growing counties sit. The 2022 census counted 265 Sampson farms between 10 and 49 acres and 285 between 50 and 179.
