The City of Charleston Building Inspections Division permits through the Customer Self Service portal, with historic easements, a PDF-only upload policy and a doubled fee for work started without a permit.
This Charleston building permit guide covers what requires a permit, the CSS portal, the over-the-counter window, the PDF-only upload policy and the notification gap that stalls applications, how sub-trade inspections are scheduled, and what historic district review adds.
Scope: inside the City of Charleston limits, across Charleston and Berkeley counties. Outside them, the relevant county or municipality permits.
Historic easements remove the over-the-counter route. Charleston allows some permits to be walked through the Permit Center between 9:00am and 4:30pm — but not where a Historic Charleston Foundation or Preservation Society of Charleston easement attaches, or where there is a Substantial Improvement issue. Establish the easement position before promising a date.
What requires a permit in Charleston?
The Building Inspections Division, within the Department of Public Service, issues permits at 2 George Street on the ground floor, with applications, payments and inspection scheduling through the Customer Self Service (CSS) portal. Inspections are on 843-724-7441.
The city splits inspection responsibility three ways: Building Inspections for building, mechanical, electrical, plumbing and fuel-gas; the Fire Marshals Division for fire-related permit inspections; and the Engineering Division for engineering and right-of-way inspections. Depending on the project, further approvals come from Engineering Services, the Board of Zoning Appeals, the Technical Review Committee, and in historic districts the BAR or DRB.
Get the permit before starting. The city typically doubles the permit fee for work started without one, and building unpermitted exposes the owner to penalties and stop-work orders. Charleston also operates a Third Party Inspection Program — the third private-provider arrangement documented in this library, alongside Pawleys Island and the City of Laurens.
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.

Charleston building department: who handles permitting
Over-the-counter approval is possible but never guaranteed. Certain permit types can be walked through the Permit Center from 9:00am to 4:30pm for in-person approval, provided the submittal is complete and there are no Substantial Improvement issues, no Historic Charleston Foundation easements, no Preservation Society of Charleston easements, and nothing else that may not be readily apparent.
Sub-trade inspections are scheduled under the building permit, not under their own record. Electrical, mechanical, plumbing and fuel-gas inspections on a project are found and scheduled inside the building permit. Stand-alone trade permits are the exception — those are scheduled within the trade permit itself. That is the opposite convention from Spartanburg County, where every trade schedules under its own number.
Payments are made through CSS, and a CSS account is not required to pay — searching the invoice number is enough. Once an application is approved, the billing contact in the city's system receives the invoice.

Solar permits in Charleston
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 inside the City of Charleston is scheduled for inspection under the project's building permit rather than under its own record, unless it is filed as a stand-alone trade permit. In a historic district, BAR or DRB review applies to a visible rooftop array. 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 Charleston
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 inside the City of Charleston in a historic district needs BAR or DRB review, because roof covering is visible exterior work. The address and permit placard must be posted visible from the road and accessible to the inspector. 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.
Charleston permit cost
The city publishes a Building and Trade Permit Fee Schedule, and fees scale with the type and valuation of the work. Payment is made through CSS, where a search of the invoice number allows payment without a portal account.
The most expensive fee decision is starting early. The City of Charleston typically doubles the permit fee for work started without a permit, on top of penalty exposure and stop-work orders. Confirm current amounts against the published schedule before budgeting.
| Fee component | How it works |
|---|---|
| Building permit | Per the published building and trade permit fee schedule |
| Trade permits | Mechanical, electrical, plumbing, fuel-gas charged separately |
| Unpermitted work | Permit fee typically doubled |
| Payment | Through CSS; no account needed if you have the invoice number |
| Historic review | BAR or DRB calendars drive the schedule as well as the fee |
| Coastal critical area | SCDES authorisation is separate and additional |

Charleston trade permits
Mechanical, electrical, plumbing and fuel-gas work each need a South Carolina licensed contractor. Four Charleston specifics:
Schedule sub-trades inside the building permit
All sub-trade inspections — electrical, mechanical, plumbing and fuel-gas — are scheduled under the project's building permit. Go into the building permit to find them. Stand-alone trade permits are scheduled within the trade permit.
Post the placard where the inspector can reach it
The address and permit placard must be posted and visible from the road or street, and the placard must be accessible to the inspector.
PDF only, and tell them you uploaded
City policy accepts only .pdf files, and staff do not receive notifications when documents are uploaded through CSS. Email the permits address after uploading supplemental documents.
Online beats email
Online submittals are processed in priority order ahead of email submittals, so the portal route is faster even when both are available.
Charleston permit application: how to apply step by step
Here is how to get a building permit in Charleston, from confirming the requirement through to close-out. Each step below corresponds to a real decision point where projects commonly stall.
Charleston spans Charleston and Berkeley counties and is surrounded by other municipalities and unincorporated county. Settle the city limit from the parcel.
Work in a historic district needs BAR or DRB review. Historic Charleston Foundation and Preservation Society of Charleston easements both remove the over-the-counter option.
CSS handles permit applications, inspection scheduling and business licence updates. Online submittals are processed ahead of email submittals.
City policy accepts .pdf only. After uploading supplemental documents, email the permits address, because staff receive no notification of uploads.
Some permit types can be walked through the Permit Center between 9:00am and 4:30pm for possible over-the-counter approval, given a complete submittal and no easement or substantial improvement issues.
Post the address and permit placard visible from the road and accessible to the inspector. Schedule sub-trade inspections under the building permit, and stand-alone trade inspections within their own permit.
Inspections in Charleston
Inspections are performed Monday through Friday except city-designated holidays, and are scheduled through CSS. The address and permit placard must be posted and visible from the road or street, and the placard accessible to the inspector.
The scheduling convention is the thing to internalise. All sub-trade inspections — electrical, mechanical, plumbing and fuel-gas — are scheduled under the project's building permit, and you go into the building permit to find them. All stand-alone trade permit inspections are scheduled within the trade permit. Getting this backwards is the most common reason a Charleston inspection request does not appear.
The city also operates a Third Party Inspection Program and publishes a Certificate of Construction Completion process and Building Code Board of Appeals information. On a complex or fast-tracked project the third-party route is worth asking about early rather than late.
Keep the permit and approved plans available throughout, with the placard posted and reachable. Appeals go to the Building Code Board of Appeals.
