Barndominium Builders in Chesterfield County, SC

Also worth knowing before you build in Chesterfield County

Who enforces where — and four towns in this county have no zoning at all

Chesterfield County has more separate jurisdictions inside it than any of its neighbours, and which one you answer to is worth settling before an offer rather than after. Building permits for the unincorporated county come from Chesterfield County Building Codes, 178 Mill Street, Chesterfield SC 29709, on 843-623-9615, with Derrick Outen as Director and Andrew Smith and Calin Jowers listed alongside him as inspectors. Permitting has moved to an online portal and the department's own page states that applying now requires creating an account there. The county's adopted comprehensive plan sets out the split of responsibility in a single sentence: "The county and municipalities each administers its own zoning and municipal codes enforcement, although the county administers building construction codes enforcement for Chesterfield, Jefferson, and Patrick." So the county building department is also the building department for those three towns, while Cheraw, Pageland, McBee, Mount Croghan and Ruby run their own building enforcement. On the land-use side the same plan records that "zoning has not been adopted for the towns of McBee, Ruby, Mt Croghan, or Patrick" — four incorporated towns inside a county whose unincorporated area is entirely zoned. Planning is joint rather than county-only: a Joint Planning Commission serves the county together with Cheraw, Chesterfield, Jefferson, McBee, Mount Croghan, Pageland, Patrick and Ruby, meeting on the fourth Thursday of each month at 5:30 pm in County Council chambers and not meeting in November or December unless a special meeting is called. The codes themselves are the State's and not the county's: S.C. Code § 6-9-10(A) requires every county and municipality to enforce the Building Codes Council's codes and to "enforce only" them, and Regulation 8-236(C) prohibits a local jurisdiction from writing or publishing any other building code — which is why the department's own page simply links out to the 2021 International Residential Code and the South Carolina Residential Code rather than publishing a local edition. Onsite wastewater is not a county permit either; it comes from the South Carolina Department of Environmental Services under Regulation 61-56, and the department's page directs enquirers to perk test contact information.

If you build it yourself, the county hands you the statute — and a recording requirement people miss

Chesterfield County publishes the owner-builder disclosure form on its Building Codes page, and it is worth reading before you decide to act as your own builder, because the second half of it catches people out long after the house is finished. The form is headed "Disclosure Statement For Exemption to Section 40-59-260 (A) Of Title 40, Chapter 59, Code Laws of South Carolina", and the statutory notice it reproduces reads in part: "State law requires residential construction to be done by licensed residential builders and specialty contractors. You have applied for a permit under an exemption to that law. The exemption allows you, as the owner of your property, to act as your own builder even though you do not have a license. You must supervise the construction yourself. You may build or improve a one-family or two-family residence. The building must be for your own use and occupancy. It may not be built for sale or rent. If you sell or rent a building you have built yourself within two years after the construction is complete, the law will presume that you have built it for sale or rent, which is a violation of this exemption. You may not hire an unlicensed person as your residential builder or specialty contractor. It is your responsibility to make sure that people employed by you have licenses required by state law and by county or municipal licensing ordinances. Your construction must comply with all applicable laws, ordinances, building codes, and zoning regulations." The form is signed before the Building Official and notarised. The part the county reproduces below the signature block is the one that is easy to miss: "Chapter 59, 40-59-260 (E) If a residential building or structure has been constructed by an owner under the exemption provided for this section, the owner of the residential building or structure must promptly file as a matter of public record a notice with the register of deeds, indexed under the owner's name in the grantor's index, stating that the residential building or structure was constructed by the owner as an unlicensed builder. Failure to do so revokes the statutory exemption." That is a recording step at the courthouse, not at the permit counter, and the consequence of skipping it is retrospective. For anyone using contractors instead, the boundary is a dollar figure: § 40-59-20(6) brings residential building within the Residential Builders Commission's licensing requirement where the cost of the undertaking exceeds five thousand dollars, and the general contractor route under Title 40, Chapter 11 bites above ten thousand dollars. A barndominium is far above both.

Deep sand, twelve inches of footing, and the inspection checklist the county actually uses

Chesterfield County sits in the Sandhills, and the Forestry Commission's description of the ground under Sand Hills State Forest — "generally arid conditions with deep infertile sands deposited by a prehistoric sea" — is a fair description of a great deal of the county. Deep clean sand is a specific set of building conditions rather than a general one, and the two failure modes sit on adjacent parcels. Sand has good bearing but no cohesion, so a monolithic turned-down edge trench cut in dry Sandhills sand ravels rather than standing as an earth form, which is why sand sites need form boards where clay sites get an earth-formed trench; and an embedded post-frame post has good end bearing but weak lateral passive resistance in the loose upper metre, which is exactly the capacity a tall, light, wind-loaded barndominium relies on to resist overturning. The other failure is the opposite: a fragipan or plinthic horizon perching water on top of itself under a surface that looks bone dry in August. That is what disqualifies a septic site, and it is invisible from the surface. Onsite wastewater is permitted by the South Carolina Department of Environmental Services under Regulation 61-56, not by the county; § 200.5 disqualifies a site where a restrictive horizon sits within twelve inches of the deepest point of effluent application, § 200.6 keeps no part of the system within five feet of a building or property line, 75 feet of a private well, 100 feet of a public well or 25 feet of a drainage ditch, and § 200.7(1) requires a usable repair area of at least half the size of the original system — which, on a wide barndominium footprint, is usually what fixes where the pad goes. Get a Professional Soil Classifier onto the tract before you close. On the construction side the county publishes its New Build Inspection Checklist, which tells you exactly what the inspector will look at and is unusually specific for a county document: the project address clearly marked; setbacks, projections and openings verified in relation to property lines; approved plans and the permit on site and weather-protected at all times; all exterior footings placed at least twelve inches below undisturbed soil, with formed footings only allowed below undisturbed grade plane; loose soil, mud and water removed from the bottom of the footing; rebar grade, size, spacing, splicing and cover checked; a minimum of seven inches of anchor bolt embedded when concrete is poured; slabs a minimum 3.5 inches thick and capable of carrying all loads; reinforcing mesh raised on chairs and off the poly; termite treatment required with a treatment letter provided before final inspection; and the top of the stem wall projecting a minimum of six inches above finished grade with surface drainage away from foundation walls a minimum of six inches over the first ten feet.

A barndominium is never a farm structure, however the fee schedule reads

The gap on Chesterfield County's own valuation sheet between an agricultural building and a dwelling — $10.00 per square foot against $120.00 — makes the farm-structure question more tempting here than in most counties, so it is worth settling properly. S.C. Code § 6-9-65(B) prevents a local government enforcing a nationally recognised building code against a farm structure. Subsection (A) then defines a farm structure as one built on a farm "other than a residence or a structure attached to it". A barndominium is a residence, so it sits outside the exemption from the first day, and the shop half of a shouse sits outside it too because it is attached to a residence. There is no square-footage test and no percentage-of-use test to argue with. Subsection (C) makes the exemption conditional on an affidavit filed with the local building official before construction begins, and the definition expressly excludes a structure that originally qualified "but later converted to another use" — which is precisely what permitting a shell as agricultural and finishing the living end later would be. The contractor licensing side reaches the same conclusion independently, and in a county where the answer is often a metal building on a slab it is the more directly useful framing. The "Pre-engineered Metal Buildings" subclassification at § 40-11-410 covers a building "consisting of no more than a concrete floor slab, metal frame, metal roof, metal sidewalls, foundations, and building insulation" — a finished dwelling is more than that list, so that subclassification standing alone does not reach it. The "Wood Frame Structures" subclassification at § 40-11-410(4)(l) covers framing, roofing, siding or flooring for wood-framed structures over five thousand square feet used for housing livestock, storage or processing "when such structures are not used for habitation or office facilities", so a post-frame building leaves that subclassification the moment it becomes a dwelling. Note also that the county's own setback sheet uses the phrase "accessory farm buildings or structures housing livestock, swine or fowl" in footnote 6, which is about siting rather than about code exemption and should not be read as blessing a residential building as agricultural. Permit it as a dwelling from the start, with the shop bay in the drawings, and take the valuation question to Codes Enforcement openly rather than through a classification that will not survive an inspection.
