Berkeley County Building and Codes Enforcement requires plans designed by a South Carolina licensed engineer or architect — for residential as well as commercial — to a minimum of 133 mph wind and D-2 seismic.
This Berkeley County building permit guide covers the 133 mph wind and D-2 seismic design criteria, the licensed design professional requirement, the 10am inspection cut-off, the Community Rating System flood discount, and the county's warning about fake invoice emails.
Scope: unincorporated Berkeley County. Goose Creek, Hanahan, Moncks Corner and part of Summerville permit their own work.
Verify every invoice against the Builder's Portal. Berkeley County warns about imposter email scams containing fake invoices. Invoices are accessed from, and payments submitted through, the portal — nowhere else. This is the sixth jurisdiction across four states in this library to publish such a warning.
What requires a permit in Berkeley County?
Berkeley County Building and Codes Enforcement enforces the latest South Carolina state-adopted versions of the International Building, Residential, Mechanical, Plumbing and Gas Codes, the International Fire Code, the International Energy Efficiency Code and the National Electrical Code. Permitting sits alongside it as its own department, on 843-719-4292 at Moncks Corner with satellite contact through Charleston and St. Stephen.
Berkeley is one of South Carolina's eight coastal counties — and it has no oceanfront. This county is in the Coastal Zone but has no oceanfront. That combination is misunderstood constantly, in both directions. The critical area regime does apply — SCDES holds direct authority over structures and alterations in coastal waters and tidelands here, so dock, bulkhead, marsh-edge and tidal-creek work needs SCDES authorisation alongside the local building permit. But the beachfront baseline and setback system does not apply, because there is no beach/dune system critical area to draw the lines against. Do not let a consultant apply oceanfront setback rules to a tidal creek lot, and do not assume the absence of a beach means the absence of SCDES.
The design criteria are published and they are not trivial. Plan submittals must meet a minimum of 133 mph winds, with “D” seismic for commercial and “D-2” seismic for residential. Seismic design is easy to overlook this far from a fault-line reputation, but the Charleston area's seismic history is why these numbers look the way they do.
The enforced code is the South Carolina Building Codes — the International Codes as adopted with South Carolina modifications by the South Carolina Building Codes Council under S.C. Code Ann. § 6-9-50, then administered and enforced locally. South Carolina is mid-changeover. The codes in force today are the 2021 South Carolina Building Codes, effective 1 January 2023. On 26 August 2025 the Building Codes Council adopted the next cycle — the 2024 editions of the International Building, Residential, Fire, Plumbing, Mechanical and Fuel Gas Codes, together with the 2023 National Electrical Code — and set the implementation date for every municipality and county as 1 January 2027. Design to the 2021 codes for a permit pulled now; design to the 2024 codes for anything that will be applied for after the turn.

Berkeley County building department: who handles permitting
Building plans must be designed by a State of South Carolina licensed Design Professional — an engineer or architect — for residential as well as commercial. That is a materially higher bar than most South Carolina counties, which accept owner or builder drawings for straightforward dwellings. The county publishes exceptions to the residential requirement under its building regulations, so check those before assuming either way.
The Builder's Portal carries a dashboard, applications, inspection scheduling and a Joint Plan Review function with bookable sessions. For major subdivision and infrastructure construction plans, final plats and single-site development plans, the county runs a Concurrent Departmental Plans Review Process — Planning and Zoning is on 843-719-4095 for those.
One practical caution on the portal: it synchronises from the county's internal system on a delay, typically within three hours but potentially up to twenty-four. Information entered internally will not appear online immediately, and the county provides the data as a courtesy without guaranteeing accuracy. Do not conclude from a portal gap that something has not been filed.

🌊|In the Coastal Zone, but no beach. Berkeley's tidal creeks, marsh edges and the Cooper River system are coastal waters and tidelands critical areas, so SCDES authority is real here even though no beachfront line exists. A building permit is not a coastal permit. SCDES authorisation is required for all proposed activities located wholly or partially within the state's critical areas, and that authorisation is separate from — and additional to — the county or municipal building permit. Neither one substitutes for the other, and a local permit issued in ignorance of a critical area does not cure the omission.
Berkeley County permits: record types and what each covers
Berkeley County issues building and trade records through the Builder's Portal, with plan cases running alongside through Planning and Zoning:
Residential permit types
| Permit type | What triggers it | Review path | Fee basis |
|---|---|---|---|
| New construction | New dwellings, additions, and accessory structures above the local size threshold | Full plan review against the adopted South Carolina Residential Code, plus zoning | Valuation-based |
| Renovation / alteration | Structural changes, layout changes, or added plumbing, mechanical, or electrical | Plan review scaled to scope; the property maintenance and existing-building provisions apply only where locally adopted by ordinance | Valuation-based |

Solar permits in Berkeley County
Solar is reviewed on two tracks at once across South Carolina: the electrical side (conductors, overcurrent protection, rapid shutdown, labelling, and the service or supply-side connection, against the adopted National Electrical Code) and the structural side (attachment detail, rail spacing, and whether the existing framing carries the added dead load).
Solar in Berkeley County has to satisfy the county's published design criteria — a minimum of 133 mph wind on the array attachment is a real structural question, not a formality — and building plans must be designed by a South Carolina licensed design professional. Confirm which classifications your installer actually holds before the application is filed, because a single rooftop array can cross the general contractor Miscellaneous Metals subclassification for the panels, Roofing or Building for the mounting, and a mechanical contractor holding Electrical for the wiring and connections.
The licensing split is the part that catches installers. South Carolina puts solar panel installation under the general contractor Miscellaneous Metals subclassification, but roof mounting may only be performed by a general contractor holding Roofing or Building, and wiring and connections may only be performed by a mechanical contractor holding Electrical. Structural upgrading of the roof to carry the array goes to a general contractor with Building or Structural Framing. One array, potentially three licences.
Utility interconnection runs on its own clock alongside the permit. Dominion Energy South Carolina, Duke Energy Carolinas and Duke Energy Progress, Santee Cooper and the state's electric cooperatives each set their own application, meter, and witness-test sequence. Permission to operate is not something the building department controls, so plan for the two tracks to finish at different times.
Roofing permits in Berkeley County
A roof covering replacement needs a permit across most of South Carolina. The permit is usually quick, but it is not optional, and the inspection that matters happens before the covering goes on rather than after.
Because South Carolina enforces a statewide adopted code, there is no state product-approval database to search and no approval number to cite on the application. The assembly has to comply with the adopted code and the manufacturer's listed installation instructions, and that pairing is what the inspector checks — which makes the manufacturer's instructions a document worth having on site.
A reroof in Berkeley County is booked for inspection before 10:00am for next-day service, with the invoice paid through the Builder's Portal rather than against any emailed invoice. Roofing is its own general contractor subclassification in South Carolina, and it absorbed the former General Roofing and Specialty Roofing classifications, so an older pocket card can read differently from the current licence record — check the LLR verification lookup rather than the card alone.
Sequencing is where reroofs go wrong. The deck and dry-in condition has to be visible when the inspector arrives, so covering it first means opening it back up. Where a previous layer has been torn off, expect attention to deck fastening and to any sheathing replaced along the eaves.
Berkeley County permit cost
Berkeley County permit fees follow the county schedule and scale with the type and valuation of the work, with trade permits charged as their own records. Invoices are accessed from, and online payments submitted through, the Builder's Portal — and only through the Builder's Portal.
One cost that runs the other way: because unincorporated Berkeley County participates in the Community Rating System, residents receive a discount on flood insurance premiums. On a floodplain parcel that discount is a real line in the owner's operating costs, and it is worth mentioning to clients. Confirm current fee amounts against the county schedule before budgeting.
| Fee component | How it works |
|---|---|
| Building permit | Per county fee schedule, by type and valuation |
| Invoices and payment | Builder's Portal only — beware fake invoice emails |
| Design professional | Licensed engineer or architect required on plans |
| Trade permits | Electrical, mechanical, plumbing, gas charged separately |
| Flood insurance | CRS participation gives residents a premium discount |
| Coastal critical area | SCDES authorisation is separate and additional |

Berkeley County trade permits
Electrical, mechanical, plumbing and gas work each need their own permit and a South Carolina licensed contractor. Four Berkeley County specifics:
Design to 133 mph and D-2
Plan submittals must meet a minimum of 133 mph winds, with D seismic for commercial and D-2 seismic for residential. Interpolation applies for wind where relevant to the site.
A licensed design professional signs the plans
Building plans must be designed by a State of South Carolina licensed engineer or architect for residential and commercial alike, subject to published exceptions for residential.
10am for next day
Requests for inspection made before 10:00am will receive next-day inspections. Later requests roll forward.
Pay only through the portal
Invoices are accessed from, and online payments submitted through, the Builder's Portal. The county warns about imposter email scams containing fake invoices.
Berkeley County permit application: how to apply step by step
Here is how to get a building permit in Berkeley County, from confirming the requirement through to close-out. Each step below corresponds to a real decision point where projects commonly stall.
Goose Creek, Hanahan, Moncks Corner and part of Summerville sit inside Berkeley County and permit their own work. Note that Summerville spans three counties.
Berkeley is in the eight-county Coastal Zone. Tidal creek, marsh-edge and dock work needs SCDES authorisation. Check the floodplain mapping too, since the unincorporated county participates in the Community Rating System.
Building plans must be designed by a State of South Carolina licensed engineer or architect for residential as well as commercial, subject to the published residential exceptions.
A minimum of 133 mph wind, D seismic for commercial and D-2 seismic for residential. Use the county's residential submittal requirements and square footage schedule for a new single-family residence.
Apply, track and pay through the portal, remembering it synchronises on a delay of up to twenty-four hours from the county's internal system.
Requests made before 10:00am receive next-day inspections. Keep the permit and approved plans on site through to Certificate of Occupancy.
Inspections in Berkeley County
Berkeley County's inspection scheduling runs through the Builder's Portal, and the rule is simple: requests made before 10:00am receive next-day inspections. Typical checkpoints follow the adopted code sequence through footing, rough-ins, framing, insulation and final.
The portal also carries a Joint Plan Review function with bookable sessions, and the county runs a Concurrent Departmental Plans Review Process for major subdivision and infrastructure construction plans, final plats and single-site development plans. On a development project the concurrency is worth using deliberately rather than discovering late.
Remember the portal's synchronisation delay when reading inspection results. Information entered internally typically appears online within three hours but can take up to twenty-four, and the county provides it as a courtesy without guaranteeing accuracy. When something matters, telephone rather than infer.
Keep the permit and approved plans on site throughout, and verify any invoice against the Builder's Portal before paying it.
