Do you need a building permit in Spartanburg County, South Carolina?
Yes. Unincorporated Spartanburg County requires a building permit for new construction, and the Building Codes Department issues residential building, electrical, plumbing and mechanical permits1. The department enforces the South Carolina Building Code along with local land-use rules5. South Carolina's current mandatory codes took effect in 2023; newer code editions become mandatory in 2027, so ask the department which edition will govern a project that crosses that changeover1112. A qualifying farm structure may receive a limited building-code exemption after the owner files the required affidavit, but the exception does not cover a residence or a structure attached to one, does not protect a later conversion to another use, and does not prevent the county from issuing a permit10.
Who is the Spartanburg County Building Codes Department, and how do you reach them?
The Building Codes Department is at 366 N Church St, Main Level, Suite 500 in Spartanburg, and can be reached at 864-596-27275. Permit and inspection fees are set locally rather than by a single statewide fee schedule, so confirm current costs with the department before budgeting13. Once you have a permit, inspections are carried out under the code edition that was in effect when the original permit was issued, which matters if the state's codes change while your project is underway14.
Does Spartanburg County have zoning?
Yes. Unincorporated Spartanburg County operates under the Performance Zoning Ordinance in the Southwest Planning Area and the Unified Land Management Ordinance in the rest of the county2. Neither ordinance assigns traditional residential, commercial or similar classifications at the parcel level, but that does not mean a parcel is unrestricted3. Sign rules apply throughout the unincorporated county, while nonresidential architectural standards apply along arterial and collector streets across the county's jurisdiction2. In the ULMO area, lot frontage is also controlled by the Subdivision Regulations, with the larger applicable frontage requirement governing9. Spartanburg County Planning and Development is the office to ask which ordinance covers a tract and how its use, frontage and development standards apply1516. The available rules do not confirm a countywide minimum dwelling size, lot-coverage limit or accessory-dwelling rule, so ask Planning and Development before relying on a seller's description.
How do septic permits work in Spartanburg County?
Septic permitting in Spartanburg County runs through the South Carolina Department of Environmental Services rather than the county46. A home or manufactured home on land without public or community sewer needs state site approval and a septic installation permit before the county can issue its building permit17. The installer must contact SCDES for an inspection before covering a new system; if the inspector does not arrive within 30 minutes of the scheduled time, a licensed installer may self-inspect and submit the required state form18. Public-sewer access must be checked early because SCDES cannot issue an onsite wastewater permit where public sewer is accessible19. About 60.5% of county soils are rated without severe limitations for a conventional drain field, but each lot still requires its own evaluation20. A private residential well requires a Notice of Intent before drilling and carries a $70 state fee7.
Can you live in an RV or tiny home on your land in Spartanburg County?
This is unconfirmed at the county level and is worth a direct call to Planning and Development, because Spartanburg's zoning does not classify parcels the traditional way and RV or tiny-home occupancy rules may sit inside either the PZO or the ULMO depending on where your land is1615. South Carolina's only statewide camping-duration rule caps campsite occupancy at fourteen consecutive days without permission from the Department of Parks, Recreation and Tourism, but that rule governs state-park campsites, not living in an RV on privately owned land, so it does not answer this question21.
Building a home in Spartanburg County: the steps, in order
- Ask Spartanburg County Planning and Development whether the tract is in the PZO or ULMO area and which use, frontage and subdivision standards apply2915.
- If the tract will be divided, submit the split for the applicable county review; even a division into parcels of 5 acres or more with no new street must be received and marked as an information record22.
- If public sewer is not accessible, obtain SCDES site approval and a septic installation permit before seeking the county building permit1719.
- Submit plans to the Spartanburg County Building Codes Department and arrange required inspections as work proceeds15.
- An owner-builder must personally appear and sign the permit application, supervise construction, use licensed contractors where required and promptly record the required notice; sale or rent within 2 years creates a presumption against the exemption8.
- If a driveway enters a state highway, obtain the SCDOT permit before building within the state right-of-way23.
What to check before you buy land in Spartanburg County, South Carolina
Ask Planning and Development which ordinance covers the parcel and whether its frontage or a planned land division triggers county review2915. About 60.5% of county soils are rated without severe limits for a conventional drain field, but SCDES still evaluates the individual site2017. About 67.6% of the county is wooded, so inspect the actual building envelope and access route rather than estimating clearing from aerial imagery alone24. Check flood maps before assuming a farm building is exempt from development constraints: qualifying farm structures remain subject to National Flood Insurance Program standards, and residences and structures attached to them do not receive the farm-structure exception25. Typical property tax bills are about $1,217 a year at an effective rate near 0.6%, but verify the parcel's assessment and exemptions before closing2627.
Watch-outs
- Spartanburg County's two zoning ordinances do not assign traditional parcel-level classifications, but use, frontage and other development rules still apply; confirm the tract's ordinance with Planning and Development23915.
- Living in an RV or tiny home on your own land in Spartanburg County is unconfirmed; ask Planning and Development directly rather than assuming the state's 14-day state-park camping rule applies1521.
- If you use South Carolina's owner-builder exemption, you must personally sign the permit, supervise the work and promptly record the required notice; missing that filing revokes the exemption8.
- A farm-structure code exemption does not cover a residence or attached structure, and qualifying farm structures remain subject to National Flood Insurance Program standards1025.
