Knox Heritage Window Replacement Guidelines Explained

Why Window Replacement Is Not A Simple Swap In Historic Districts

A permit is more likely when the project changes the opening size, touches framing, or affects the building shell in a structural way. Even if a permit is straightforward, the historic side of the project may still need approval.
