Building permits in unincorporated Anderson County — an Upstate county on Lake Hartwell near Clemson — are issued by the Building & Codes Department, with applications through the County's OpenGov online permitting portal. The department enforces the adopted codes for both the construction and mobile-home industries.
This Anderson County building permit guide covers what requires a permit, how fees work, the OpenGov process, trade permits, and inspections — so your Anderson County project starts clean.
Anderson County issues permits for unincorporated areas only. Cities — Anderson, Belton, Clemson, Williamston, and others — run their own building departments. The County enforces the 2021 International Codes with South Carolina modifications and runs a Special Inspection Program; resubmit with all corrections at once, since partial corrections restart the review.
What requires a building permit in Anderson County?
Under the South Carolina building codes (the International Codes as adopted with South Carolina modifications by the South Carolina Building Codes Council, then locally administered and enforced), a permit is required before you construct, enlarge, alter, repair, move, demolish, or change the occupancy of most structures and systems. Common triggers include:
Permit required
- New construction, additions, and renovations
- Structural / load-bearing alterations and demolition
- Reroofing, windows, doors, and exterior changes
- Electrical service changes and most wiring alterations
- Mechanical / HVAC installations and changeouts
- Plumbing alterations, repipes, and water heaters
- Decks, pools, accessory structures, and signs
- Change of occupancy or use
Typically exempt
- Painting, flooring, cabinetry, and cosmetic work
- Like-for-like fixture/device swaps by a licensed contractor
- Routine maintenance not altering structure or systems
- Small projects expressly exempt by code (confirm first)
Exemptions are narrow and scope-specific. When unsure, confirm with the building department before starting — see the penalty note below.
Get the permit issued before starting work. Building without one exposes the owner to penalties and stop-work orders. When responding to a deficiency list, address every item before resubmitting — partial corrections restart the review clock.
Who handles permitting in Anderson County?
Permitting, plan review, and inspections run through the Building & Codes Department for both construction and mobile-home projects. Applications — building, electrical, mechanical, plumbing, compliance, and land-use permits — are filed through the OpenGov portal with a registered account.

Anderson County trade permits
Electrical, plumbing, and mechanical work needs its own permit and a South Carolina-licensed contractor, each filed in OpenGov.
Electrical permits
Required for service upgrades, panels, solar PV, generators, and most wiring, performed by a SC-licensed electrical contractor (see the County's generator checklist).
Plumbing permits
Required for new plumbing, repipes, water heaters, fixtures, and gas piping, performed by a SC-licensed plumbing contractor.
Mechanical (HVAC) permits
Required for HVAC changeouts, ductwork, and refrigeration, performed by a SC-licensed mechanical contractor. Specialized systems are permitted and inspected separately.
Miscellaneous & specialty
Reroofs, decks (per R507), pools, accessory structures, and signs are permitted separately. Pools require a Pool Fence Affidavit for barrier requirements, modular buildings follow the SC Approved Modular Building Checklist, and townhomes have their own plan-submittal checklist.
Verify your contractor's license. South Carolina licenses commercial general and mechanical contractors through the SC Contractor's Licensing Board, and residential builders, residential specialty contractors, and home inspectors through the SC Residential Builders Commission — both under the SC Department of Labor, Licensing and Regulation (LLR). A license is generally required once the value of the work exceeds $5,000 (S.C. Code 40-11-260 for commercial/mechanical; the Residential Home Builders Act for residential). Verify before signing; the property owner is responsible for ensuring a permit is obtained.
