Do I need a permit for window or exterior door replacement in Charleston?
It depends. Whether window or exterior door replacement needs a permit in Charleston comes down to the details of your project.
Near the Charleston coast, replacement windows and doors may need to meet windborne debris impact or design pressure requirements, which changes the products you can buy. A bedroom window usually has to keep a minimum emergency escape (egress) opening. Confirm the required clear size before replacing a bedroom window with a smaller unit. Charleston treats in-kind window replacement as an express permit that may be handled over the counter, so a like-for-like window swap in an existing opening still goes through the Permit Center, while cutting a new opening, enlarging an opening, or altering a header is a fuller building permit. In the Old and Historic District the appearance of windows and doors is regulated, so changing window style, material, or configuration, or altering a door visible from the public right of way, can require a Certificate of Appropriateness from the Board of Architectural Review before any permit is issued. Because the city errs toward requiring review, confirm your exact scope through the Customer Self Service (CSS) portal or with the Permit Center rather than assuming a swap is exempt, since a false no-permit assumption is the risky direction. Enlarging an opening, moving it, or cutting a new one is structural work. Exemptions that cover replacing a unit in its existing opening do not reach it, so a permit is required. Changing an opening usually means a new or resized header, and many jurisdictions want a beam detail or engineering before they will issue, so allow for that in the schedule.
