Q: Can the shop be bigger and taller than the house here?

It depends entirely on whether it is one building or two, and in Abbeville County the difference is larger than in most. If the shop is a separate detached building, you run into § 6.1.8, which lists what counts as a customary accessory use. The list for a dwelling names a "private garage not to exceed the following storage capacities: one- or two-family dwelling: 4 automobiles", a shed or tool room for grounds and building maintenance equipment, a kennel, a pool and bath house, a dock or boat house, and a greenhouse or slat house under eight feet. A large detached workshop is not on it, and § 4.2.3(E) states a prohibition that "applies to this district and all other zoning districts of this Ordinance: Any use not listed as permitted, or permitted as a special exception, a conditional use, or an accessory use, is prohibited." Section 6.1.9 also makes an accessory structure observe the full district setbacks, so it gets no relief the house does not. If instead the shop bays and the living space are one continuous structure under one roof, what you have is a dwelling with a large garage — the principal building — and none of that engages, because there is no accessory building. In FA the principal building faces no maximum height at all, on a two-acre minimum lot with a 50-foot front yard and 30-foot side and rear yards. That is the form that works here. Two cautions: every square foot under that roof is part of the dwelling for building-code purposes, so the residential code's separation, fire and energy requirements follow the shop bay across the common wall; and this is a reading of the ordinance, not a determination. Take the drawing to the Zoning Administrator at 903 W. Greenwood Street and get it in writing before you commit.

Q: Can I run my business out of the shop?

In the Forest Agricultural and Rural Development districts, yes, and Abbeville is unusually generous about it. Section 3.7 permits a home occupation in any residential district or structure. The ordinary rules are the familiar ones — conducted by family members residing in the dwelling, within the principal building, on not more than 25 percent of its floor area, with no exterior change to the character of the building, no retail sales other than items hand-crafted on the premises, no product visible from the street, no more than two full-time non-family employees, and parking met off-street and not in a required front yard. Then two subsections change the picture on rural ground. Subsection (B) raises the employee cap in FA and RDD to "up to five (5) full-time non-family members", counted as on-premises employment. Subsection (J) says: "In FA and RDD zones, light manufacturing, wholesaling, and service-related businesses are allowed in an enclosed building not exceeding 5000 square feet in floor area. The use of accessory buildings to the principal building are allowed in these zones provided the appearance of the subject property remains agricultural/residential as viewed from the public way and business activities do not produce sound levels that are uncharacteristic of the area." The FA district repeats the 5,000-square-foot allowance as a conditional use at § 4.10.3(B)(13), approved by the Zoning Administrator, with landscape buffers or screening as the Administrator determines and the parking guidelines of § 3.7 observed. So a fabrication, cabinet or service business in a barndominium shop bay is contemplated by this ordinance rather than merely tolerated. The two tests that decide it are the 5,000 square feet of enclosed floor area and how the property looks from the road.

Q: What do I need to get a building permit, and what does it cost?

The county sets the sequence out on its own Building Codes page and the order matters, because two of the steps have to happen before the permit can issue at all. First, obtain a 911 address request form and a zoning compliance signature from the Building and Planning Department, then present the form to E911 to get the address. Second, if the property will be on septic, obtain the state septic permit — or, on an existing system, a letter from a licensed septic system contractor stating the system is adequate for the proposed home. Third, if you are building without a contractor's licence, complete the Owner Builder Disclosure Statement and record it in the Register of Deeds; the department notes that "SC Law prevents you from renting or selling your house for 2 years following completion." Fourth, submit a set of plans for a building inspector to review, allowing one to two days. Only then are permits issued, and they issue separately for building, electrical, plumbing and mechanical, with every contractor licensed by SCLLR. Any structure larger than 200 square feet requires a permit, and the department names pole buildings and metal carports specifically. On cost, the published schedule prices a building permit at $25.00 issuance plus $15.00 for the first $1,000 of valuation and $5.00 for each thousand thereafter, with plumbing and mechanical on the identical scale and a gas permit at a flat $25.00. Electrical runs off a value-of-work band table, from $30.00 at $0-500 up to $500.00 above $200,000. A certificate of occupancy is $15.00 and a re-inspection $25.00. Starting work before the permit issues doubles the original fee. Give at least 24 hours' notice when you call for an inspection.

Q: Is every parcel in the county zoned, and how do I find out what mine is?

Every unincorporated parcel is zoned. Appendix A § 1.4 is a single sentence with no carve-out: "These regulations govern the development and use of all land and structures within the unincorporated boundaries of Abbeville County." There is no unzoned designation in the applicability chapter, which sets Abbeville apart from Anderson and Oconee counties immediately to the north, where large blocks of ground sit outside the reach of a zoning ordinance. Nine districts exist: RDD Rural Development, R-8 Restricted Residential, GR General Residential, MH Manufactured Housing, GC General Commercial, LI Light Industrial, BI Basic Industrial, PDD Planned Development and FA Forest Agricultural. Finding out which one covers a tract is where care is needed. Section 1.5 provides that the Official Zoning Map "will continue to be used 'as is' until such time as the County has converted to a GIS mapping system", that all changes to the map are made by the County Planner, and — the sentence to remember — that "regardless of the existence of purported copies of the Official Zoning Map, which may from time to time be published, the Official Zoning Map, which shall be located in the County Planning Office, shall be the final authority as to the current zoning status of land and water areas, buildings, and other structures in the County." A listing sheet, a county GIS viewer or a third-party parcel map is not that authority. Where a boundary is uncertain, § 1.5 gives the interpretation rules — centrelines, platted lot lines, municipal limits, topographic contours and shorelines — and leaves the rest to the Zoning Administrator. Ask the department, on (864) 366-2400 ext. 64, and ask in writing.

Q: What is the ground like, and will it take a septic system?

Mostly favourable, with a belt through it that is not, and the septic question is the one that can end a purchase. The dominant soils are Cecil at 88,000 acres as a major component and Pacolet at 49,425 — the well-drained kaolinitic red Piedmont clays that carry a slab without special measures — plus Wilkes at 9,588 and Appling at 8,534. Toccoa at 12,023 acres and Chewacla at 7,549 are floodplain soils and usually announce themselves as bottomland. The concern is the mafic belt: 7,624 acres of Enon, 4,758 of Iredell, 3,016 of Helena, 2,422 of Winnsboro and 1,520 mapped as "Iredell variant", roughly 19,300 acres of shrink-swell ground in a county of 314,365 acres. On the foundation side that means expansive-soil design and real testing rather than a standard slab detail. On the septic side it can be decisive: onsite wastewater is permitted by the South Carolina Department of Environmental Services under Regulation 61-56, and § 200.2 provides that soils "identified as having substantial amounts of expansible layer clay minerals or smectites are unsuitable" for onsite wastewater systems, with massive or platy structure treated the same way. Abbeville is above the Fall Line, so § 104.1 requires backhoe pits rather than borings alone — the evaluation is a machine on your land, and the site has to be ready for it with property lines cleared and marked, the proposed building corners staked and the well location identified. Section 200.1 judges suitability on soil morphology, not a percolation test. You may hire a licensed Professional Soil Classifier privately and file the soil report with your application rather than waiting in the department queue, and on this county's ground that is money well spent before closing. Note the county's own permit sequence assumes it: the septic permit has to be in hand before the building permit can issue.

Q: Can I live in a camper on the land while the house goes up?

Possibly, in the Forest Agricultural district only, and not as a residence. The county's Planning and Zoning department answers it directly: "In some cases, yes — in many cases, no. In no case can a camper serve as your primary residence. Campers are allowed for periodic stays in a Forest Agricultural zoning district, provided certain conditions are met and approval is issued by the Planning and Zoning department. Campers and RV's may also be allowed under certain circumstances in the Mobile Home Park (MHP) district and in business and industrial zones, but may not be occupied in the R-8 and GR residential districts at any time." So the permission that exists is for periodic stays with departmental approval, not for eighteen months of living on site while a build finishes, and it exists in FA rather than in the residential districts. The zoning ordinance's § 6.1.20 adds conditions on parking and storing campers and recreational equipment on residential lots. If living on site during construction is part of your plan or your budget, put the question to Planning and Zoning before you make an offer, because the answer is discretionary, it is theirs to give, and it is worth having in writing. The related point people ask in the same breath: the county says the building code allows small homes and that Abbeville County ordinances "do not require any particular minimum square footage", so there is no size barrier to a compact permanent dwelling built properly from the start.

Q: Can I put up a barn now and finish it into a house later?

No, on two separate grounds, and the county says one of them itself. The statute first: S.C. Code § 6-9-65(A) defines a farm structure as one built on a farm "other than a residence or a structure attached to it", and expressly excludes a structure "originally qualifying as a 'farm structure' but later converted to another use." A barndominium is a residence, so it never qualifies, and the shop half of a shouse never qualifies either because it is attached to the residence. Even a genuinely detached agricultural barn gets only conditional relief: § 6-9-65(C) requires the owner to file an affidavit with the building official before construction stating the intended use, § 6-9-65(D) leaves the jurisdiction free to require a building permit anyway, and § 6-9-65(B) applies FEMA flood standards regardless. Then the practical ground, in Abbeville County's own words on its Building Codes page: a portable storage building "cannot easily be converted for use as a home or cabin without major demolition and reconstruction", because such buildings are "lacking in critical areas of the building code for dwellings" even where they look the part. The same logic applies to a shell put up as a barn and finished out afterwards — the foundation, the framing, the envelope and the egress all have to satisfy the residential code eventually, and satisfying it later usually means taking work apart. Design it as a dwelling from the first drawing. Remember too that any structure over 200 square feet needs a permit here in any case, so there is no size at which the question quietly goes away.

Question 1

What wind speed and seismic category apply in Abbeville County?

Accepted Answer

This is one of the few South Carolina counties where the answer is a single published figure rather than a reading off a contour map, and it comes from the body the residential code actually points at. Modification IRC 2021-04 rewrites Section R301.2.1 so the ultimate design wind speed comes from "the previously published maps by the South Carolina Building Codes Council", and IRC 2021-05 does the same for the seismic design category. Thirty-three counties get a drawn sheet, on which one county commonly carries two or three different values. Eleven counties, including neighbouring Anderson, Greenwood and Laurens, get nothing at all. Abbeville and York are the only two the Council states as a whole-county line, and Abbeville's reads: "Entire County is Seismic Category: C; Wind Category: < 115mph." Note the form of the wind value. It is a less-than, not a bare number — the Council publishes "< 115mph", and writing "115 mph" would state something firmer than the Council did. Two practical points follow. Seismic Category C is the first rung at which the IRC's seismic provisions reach a detached one- or two-family dwelling at all, so the detailing and irregularity rules apply here where they would not in a Category B county. And the rest of Table R301.2 is not published by anybody in Abbeville County: ground snow load, frost line depth, termite designation and winter design temperature are all left to the jurisdiction by the code and the county's building chapter fills none of them in. Get those cells settled in writing with the building official at plan review, before a frame or a truss package is priced.
