Question 1

Is Anderson County zoned or not?

Accepted Answer

Partly, and the ordinance says so itself, which is why the question needs rephrasing. Article 2 of Chapter 48 reads in full: "The regulations set forth in this chapter shall be applicable within the area designated on the official zoning map. The provisions of this chapter do not regulate areas designated as 'UNZONED.'" Section 3:1 then divides not the county but "the Anderson County zoning jurisdiction area" into districts. S.C. Code Section 6-29-330(A) expressly permits this — a county may plan and zone "the total unincorporated area or specific parts of the unincorporated area" — and the county's own Rezoning Process sheet confirms the practical consequence: "The rezoning process does not apply to unzoned properties in the County." So the useful question is whether your parcel is zoned, not whether the county is. Look the tax map number up on the county property viewer or ask Planning and Community Development, and if a shop larger than the house is central to your plan, get the answer in writing before you make an offer. Being unzoned is not the same as being unregulated: Chapter 24 applies to every unincorporated acre either way.

Question 2

If my land is unzoned, what actually controls where I put the building?

Accepted Answer

Chapter 24, Article II — the Land Use and Development Standards Ordinance — and its jurisdiction clause at Section 24-26 is unambiguous: "This article shall apply to all unincorporated portions of the county." Four provisions do most of the work. Section 24-117 sets the residential principal-building front setback at 30 feet from a local road, 40 from a collector and 50 from an arterial, with a 15-foot rear yard; accessory buildings take the same front setbacks except 40 feet on an arterial. Accessory buildings, courts, pools and similar structures may sit inside a required setback area, but no closer than three feet to the property line, and if they do they must stay under one storey or 15 feet, under 600 square feet of gross floor area, and occupy no more than 30 percent of that setback area — so a large shop simply goes outside the setback rather than inside it. Section 24-116 limits residential impervious surface to 55 percent of the site, which on acreage is not a constraint but on a one-acre lot with a long drive and a big apron can become one. Section 24-118 sets no maximum height, but from 30 feet upward every extra foot of height requires an extra foot of setback from every minimum building line. And Section 24-30 resolves conflicts in favour of whichever rule is more restrictive, so a recorded covenant, the flood article or the state code can each still be the binding one.

Question 3

Can the shop be bigger and taller than the house?

Accepted Answer

As far as the county's land-use rules are concerned, yes — and that is worth stating precisely because the reasons differ depending on where the parcel sits. On unzoned ground, Chapter 24 contains no floor-area cap on an accessory building and no percentage-of-dwelling test anywhere in Division 4. The only size numbers in Section 24-117 are the ones that apply if you deliberately place a structure inside a required setback area, where it is limited to 600 square feet, one storey and 15 feet. Keep the shop out of the setback and none of that applies. Height is governed by Section 24-118, which imposes no ceiling but trades height for setback one for one above 30 feet — so a 40-foot-tall building needs ten extra feet of clearance from every minimum building line. On zoned R-A ground the answer is similar but arrives differently: the R-A schedule contains no height limitation and no accessory-building size cap, only a one-acre minimum lot, 100-foot width at the building line, 30-to-50-foot front yards and 50-foot side and rear yards. Section 6:3 permits one principal building and its accessory buildings on a lot. Two cautions. If the shop and the living space share one continuous roof it is not an accessory building at all — it is the dwelling, and only the dwelling's rules apply. And if you intend to run light manufacturing, wholesaling or a service trade out of it as a home business in R-A, Section 6:11 caps that use at a completely enclosed building of 2,000 square feet and 15 feet in height, which is a much tighter number than the building rules.

Question 4

What wind speed and seismic category should my engineer design to?

Accepted Answer

Ask the Anderson County building official, in writing, and treat any figure quoted without one as unsourced. South Carolina does not use the national maps for houses: modification IRC 2021-04 rewrites Section R301.2.1 to take the ultimate design wind speed from "the previously published maps by the South Carolina Building Codes Council", and IRC 2021-05 does the same for the seismic design category. The Council has approved maps for 35 of the 46 counties. Anderson is one of the eleven it has not — the others are Cherokee, Greenville, Greenwood, Laurens, McCormick, Oconee, Pickens, Spartanburg, Sumter and Union. Both modifications let the local building official delineate the category within the jurisdiction so long as it does not surpass what the Applied Technology Council website provides, and the Council's map page says the same thing for a county with no map. The problem is that the Council's own staff comment on the 2024 cycle records that "the ATC Hazards by Location site ceased operation on December 31, 2024", with users pointed to the ASCE Hazard Tool in its place. So the honest position today is that no South Carolina authority publishes a design wind speed or seismic design category for Anderson County, the local official holds the delineation power, and the figure belongs in the plan-review correspondence before the frame is ordered rather than in anybody's brochure. The same goes for ground snow load and frost depth: the residential code leaves those cells of Table R301.2 to the jurisdiction, Anderson publishes none, and the code's own 12-inch minimum footing depth below undisturbed ground applies regardless.

Question 5

Could my unzoned land end up zoned after I buy it?

Accepted Answer

Yes, and the mechanism is unusual enough to be worth understanding before you close. Anderson zones by voting precinct, by referendum, and the county publishes the process. A resident obtains a petition form from Planning and Community Development, checks with the Registration and Elections Office to establish how many registered voters the precinct has, and gathers verifiable signatures from 15 percent of them. Elections certifies the signatures, schedules a referendum and notifies County Council. Council holds first reading of the application for zoning and refers it to staff and the Planning Commission; staff hold a public meeting on the proposed zoning map, the Commission holds a public hearing and recommends, and Council holds a public hearing for second reading. After the referendum ratifies the application, Council gives third and final reading adopting the zoning map update. Fifteen percent of a precinct's registered voters is a low bar to start it and a majority of those voting decides it, so a tract that is unzoned when you buy may not be in a few years. None of that unbuilds a lawfully built structure, but it can change what you are allowed to add later — a second shop, an accessory dwelling, a home business. If your plan depends on a future addition, permit it while the ground rules are the ones you bought under.

Question 6

Can I build it as a farm building and finish it out later?

Accepted Answer

No, and the statute closes the door in its definition rather than leaving room to argue. S.C. Code Section 6-9-65(A) defines a farm structure as one constructed 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 is outside the exemption in every case, and the shop half of a shouse is outside it too because that half is attached to the residence. There is no square-footage test and no percentage-of-use test to work with. The relief is also conditional even for a genuinely detached, genuinely agricultural barn: Section 6-9-65(C) requires the owner to file an affidavit with the building official before construction stating the intended use, and Section 6-9-65(D) leaves the county free to require a building permit anyway — which Anderson does, its own permit guide listing "Barn with Electrical" as requiring building and electrical permits. Unlike Chester and Oconee counties, Anderson publishes no farm-structure affidavit form on its website; that is a gap in the paperwork, not a gap in the law, and the affidavit is still a statutory precondition. FEMA flood standards apply to a farm structure regardless, by the express terms of Section 6-9-65(B).

Question 7

What is the ground like, and what does the county already know about it?

Accepted Answer

Better than most of the Piedmont, and the county has written down which parts are not. Section 24-91(b) names five soils as presenting severe limitations to development — Cartecay, Gwinette, Madison where slopes exceed 15 percent, Pacolet and Toccoa — and requires a soils analysis report with the preliminary plat or site plan where any of them shows on the site, approved by planning staff before a permit issues. A query against the USDA soil survey for Anderson County puts real acreage behind that list: Pacolet 24,617 acres, Cartecay 13,484, Gwinnett 4,826, Toccoa 3,344, and Madison 16,642 acres in the 15-to-25-percent slope map unit that triggers the clause. Cartecay and Toccoa are floodplain soils; Pacolet, Madison and Gwinnett are the steep eroded shoulders. Against that, Cecil maps 206,544 acres here as a major component, with Hiwassee at 46,887 — the well-drained red Piedmont clays that build normally. What Anderson does not have is the shrink-swell problem that dominates the counties along the North Carolina line: a query for Iredell, Enon, Winnsboro, Armenia, Wynott and Brewback in this survey area returns none of them, and only about 1,467 acres of Helena. There is no karst either — South Carolina's karst is a Coastal Plain limestone phenomenon and the Piedmont is crystalline rock. The county publishes no general slope threshold beyond the 15-percent figure attached to Madison in Section 24-91; what bites on a steep parcel comes from the residential code's own footing-slope limit and from the septic regulation instead.

Question 8

Who permits the septic system, and what is different in the Upstate?

Accepted Answer

The county does not. Onsite wastewater is permitted by the South Carolina Department of Environmental Services under Regulation 61-56, and Section 24-53(b)(1) makes a certificate of approval from the state for water and sewage disposal part of the county's own application package. Two provisions matter more here than on the coast. First, Anderson is above the Fall Line that separates the Piedmont from the Coastal Plain, and Section 104.1(5) requires backhoe pits rather than borings alone above it — so the evaluation is a machine on your land, not a hand auger, and Section 104.1(6) requires the site to be ready for it: property lines cleared and marked, an identification marker at the front centre of the lot, stakes at the corners of the proposed building, the septic tank and drainfield areas marked, the well location identified and a site sketch with the application. Second, suitability is judged on soil morphology rather than a percolation test: Section 200.1 asks for soil texture, depth to restrictive horizons and depth to the zone of saturation, determined by accepted soil-science methods. You may hire a licensed Professional Soil Classifier privately and file the soil report with your application instead of waiting in the department queue. Two traps catch edge-of-town acreage in a county this suburbanised: an onsite wastewater permit cannot issue where public sewer is accessible however rural the parcel feels, and the setbacks eat land — 75 feet from a private well, 100 from a public one, 5 feet from a building and a property line, and nothing under a driveway or parking area.

Question 9

What will the county charge me, and how is the figure worked out?

Accepted Answer

From a square-foot table, not from your contract, and the split is unusually relevant to this building type. The published schedule effective 1 July 2026 prices a residential building permit at $110 for construction value up to $10,000 and $110 plus $2.80 per additional $1,000 above that, with a plan review fee of half the building permit fee collected when plans are submitted. Page two states how the value is arrived at: "Residential Permit Valuation for new Construction will be based on: Minimum Heated sf = $150.00/sf; Garage/Storage Buildings = $60.00/sf; Un-Finished Basement = $40/sf; Decks = $20/sf." So the heated living end is valued at $150 a square foot and the unheated shop bay at $60, whatever either actually costs. Electrical, mechanical and plumbing permits are priced separately on their own construction-value scales — electrical starts at $100 up to $2,000 and steps down to $2.50 per thousand above $200,000, plumbing is $100 plus $4.00 per fixture — and a new dwelling pulls all four. Re-inspections are $65, renewals $75 each, and a refund request carries a $25 administrative fee with no refund at all once inspections have been done. Anderson County has adopted no impact fee. Septic and well permits are separate again and go to the state.
