Building permits in Charleston

Most construction, renovation, and repair work in Charleston, Charleston County needs a building permit from City of Charleston Permit Center. Below are the office's contact details and online portal, plus step-by-step guides for the projects homeowners ask about most, from roofing and solar to fences, sheds, pools, and HVAC.

South Carolina enforces mandatory statewide building codes adopted by the SC Building Codes Council within the Department of Labor, Licensing and Regulation (LLR), based on the 2021 International Code Council editions with South Carolina amendments (effective January 1, 2023). Permits in Charleston are issued and inspected locally: incorporated cities and towns run their own building departments, while the county building office permits construction in unincorporated areas. South Carolina sets no statewide dollar threshold that exempts work from needing a permit, so permit requirements and any minor-work exemptions are determined by the local jurisdiction where the property sits.

Who issues building permits in Charleston?
City of Charleston Permit Center issues permits for property inside Charleston, Charleston County. Your mailing city is not always the authority that permits your property, so confirm the jurisdiction before you apply. This page lists the department's phone, address, website, and online portal.
Can I pull my own permit as a homeowner in Charleston?
South Carolina's owner-builder exemption (SC Code Section 40-59-260) lets an owner in Charleston build or improve a one- or two-family residence for their own use without a residential builder license, but the owner must personally sign the permit application, sign a state disclosure statement, and file a notice with the register of deeds, and the home may not be sold or rented within two years or the exemption is presumed violated.
Is there a dollar amount under which no permit is needed in Charleston?
Not statewide. South Carolina sets no statewide dollar threshold that waives a building permit, so whether small or cosmetic work needs a permit is decided locally. Confirm the exempt-work list and any value threshold with City of Charleston Permit Center before you start.
How much does a permit cost and how long does it take in Charleston?
Fees and review times are set locally and change often, so confirm the current numbers with City of Charleston Permit Center or its online portal. Fees are usually based on the value of the work or a fixed schedule, and simple residential permits are frequently reviewed faster than new construction.
