Building permits in the City of North Charleston — South Carolina's third-largest city and home to major aerospace and military employers — are issued by the Building Inspection Department from the City's One Stop Shop, with applications filed through the Customer Portal.
This North Charleston building permit guide covers what requires a permit, how fees work, the Customer Portal process, trade permits, and inspections — so your North Charleston project starts clean.
City limits control jurisdiction. North Charleston spans multiple counties (Charleston, Dorchester, and Berkeley), so being inside the city limits — not the county line — determines that the City permits your project. Permits are valid for six months and expire if no inspection occurs within that window, requiring the process to restart.
What requires a building permit in North Charleston?
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. Permits expire if no inspection activity occurs within six months (City ordinance Ch. 5, §§ 5-310 and 5-311), requiring you to start over.
Who handles permitting in North Charleston?

North Charleston trade permits
Electrical, plumbing, mechanical, and gas work needs its own permit and a South Carolina-licensed contractor, filed through the Customer Portal.
Electrical permits
Required for service upgrades, panels, solar PV, and most wiring, performed by a SC-licensed electrical contractor.
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 (a ladder must be provided), decks, pools, accessory structures, and signs are permitted separately. Structures in a special flood hazard area require additional documentation, and required inspections (rough, final, etc.) must be called for or you risk license action.
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.
