Building permits in unincorporated Beaufort County — the Lowcountry county that includes the Bluffton and Beaufort areas — are issued by the Building Codes (Building Inspections) Department, which enforces the building, fire, and electrical codes plus floodplain regulations, and registers all manufactured homes placed in the county (including the municipalities).
This Beaufort County building permit guide covers what requires a permit, how fees work, coastal floodplain rules, trade permits, and inspections — so your Beaufort County project starts clean.
Beaufort County issues building permits for unincorporated areas. The City of Beaufort, Town of Bluffton, Town of Hilton Head Island, Town of Port Royal, and Town of Yemassee run their own building permitting (though the County registers manufactured homes countywide). Because the county is coastal, FEMA flood maps, floodplain regulations, and substantial-improvement rules drive design and elevation.
What requires a building permit in Beaufort 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
- Accessory structures under the size that triggers a permit (zoning permit still applies)
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. Work requiring a permit shall not commence until the permit card is placed in a conspicuous location and maintained until the Certificate of Occupancy.
Who handles permitting in Beaufort County?

Beaufort County trade permits
Electrical, plumbing, and mechanical work needs its own permit and a South Carolina-licensed contractor; subcontractors are listed with state and Beaufort County business-license numbers.
Electrical permits
Required for service upgrades, panels, solar PV, and most wiring (panel location and load calcs on the electrical plan), performed by a SC-licensed electrical contractor.
Plumbing permits
Required for new plumbing, repipes, water heaters, fixtures, and gas piping (riser diagram and fixture-unit water supply on the plumbing plan), performed by a SC-licensed plumbing contractor.
Mechanical (HVAC) permits
Required for HVAC changeouts, ductwork, and refrigeration (Manual J load calcs and duct layout on the HVAC plan), performed by a SC-licensed mechanical contractor.
Miscellaneous & specialty
Reroofs, decks, pools, accessory structures, and signs are permitted separately. Coastal floodplain and substantial-improvement rules affect design and elevation, and the County registers manufactured homes countywide (a paid current-year tax receipt is needed to move a mobile home out of the county).
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.
