Lexington County Window Replacement Permit Requirements Explained

If you are planning a window project in Cayce or anywhere else in Lexington County, the permit question usually comes up early, and for good reason. Window work can look simple from the street, but once you change opening sizes, alter framing, or work on a home with older construction, the paperwork can matter just as much as the glass.

The short version is that like-for-like replacement is often handled differently than a project that changes the structure of the opening. If the new unit fits the existing opening and you are not touching load-bearing framing, many jurisdictions treat it as a simpler replacement.
