Do I Need a Permit to Replace Windows in Dallas TX?

When A Window Replacement Usually Needs A Permit

For a lot of Dallas homeowners, the answer is not a simple yes or no.

That is why it helps to separate "replace" from "rebuild."

• Altering a load-bearing wall or header
• working on a historic home or a property subject to design review
• Adding a new window where none existed before
• Changing a window to meet egress, safety, or code requirements
