Building permits in the City of Charleston — South Carolina's historic coastal port city — are issued by the Building Inspections Division (Department of Public Service), with applications, payments, and inspection scheduling through the Customer Self Service (CSS) portal. Projects in historic districts also pass through the Board of Architectural Review or Design Review Board.
This Charleston building permit guide covers what requires a permit, how fees work, the CSS portal process, historic review, trade permits, and inspections — so your Charleston project starts clean.
Confirm jurisdiction first. Areas like West Ashley, James Island, Johns Island, and Cainhoy contain a mix of incorporated and unincorporated parcels — use the City's GIS map tools to verify your project is inside city limits before applying. Projects exceeding $1,000 in valuation require plan review, and historic-district work needs Board of Architectural Review (BAR) or Design Review Board (DRB) approval.
What requires a building permit in 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. The City of Charleston typically doubles the permit fee for work started without a permit, and building without one exposes the owner to penalties and stop-work orders.
Who handles permitting in Charleston?
Plan review and inspections run through the Building Inspections Division for building, mechanical, electrical, plumbing, and fuel-gas work; the Fire Marshals Division handles fire-related inspections. Depending on the project, additional approvals may come from Engineering Services, the Board of Zoning Appeals, the Technical Review Committee, and (in historic districts) the BAR or DRB.

Charleston building permit cost
Charleston building permit fees are set by the Building and Trade Permit Fee Schedule and based on the type and valuation of work, with separate trade permit fees. Projects over $1,000 in valuation require plan review, and the plan review fee is typically about 50% of the building permit fee.
Other fees may apply through the Fire Marshals Division, Business License, Engineering Services, BAR/DRB, BZA, and TRC. A 100% building-permit-fee waiver applies to new construction of single-family detached residences. Confirm current amounts before budgeting.
| Fee component | How it works |
|---|---|
| Building permit fee | Per Building & Trade Permit Fee Schedule |
| Plan review (over $1,000) | ~50% of the building permit fee |
| Trade permits (E / P / M / gas) | Charged separately per trade |
| New single-family detached | 100% building-permit-fee waiver |
| Work without a permit | Permit fee typically doubled |
| Other approvals | Fire, Engineering, BAR/DRB, BZA, TRC fees may apply |

Charleston trade permits
Electrical, plumbing, mechanical, and fuel-gas work needs its own permit and a South Carolina-licensed contractor, each filed in the CSS portal.
Electrical permits
Required for service upgrades, panels, solar PV (with engineered plans), 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, refrigeration, and fuel-gas systems, performed by a SC-licensed mechanical contractor. Specialized systems are permitted and inspected separately.
Miscellaneous & specialty
Reroofs, decks, pools, accessory structures, and signs are permitted separately. Solar PV requires engineered plans, historic-district work requires a BAR or DRB Certificate, and coastal/flood requirements affect design and elevation.
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.
