How to File a Knox Permit Portal Application for Window Replacement

When A Window Replacement Permit Is Needed

Before you order new windows, it is worth confirming whether the project needs a permit in Knox County.

What To Gather Before You Start The Portal Application

The portal moves faster when you know the scope, the products, and the contractor information before you log in.

At a minimum, be ready to explain what is being replaced, how many windows are involved, and whether any framing will change.
