Knox County Window Replacement Permit Requirements Explained

When A Window Replacement Needs A Permit

In Knox County, the permit question usually comes down to whether the job is a simple swap or a change to the structure around the opening.

enlarging or shrinking the rough opening repositioning the unit on the wall altering load-bearing framing adding a bay or bow unit changing egress conditions in a bedroom
