Do I need a permit for window or exterior door replacement in Mesa?

Permit may be required

It depends. Whether window or exterior door replacement needs a permit in Mesa comes down to the details of your project.

Simple like-for-like replacement may not need a permit in some jurisdictions, but enlarging an opening, cutting a new opening, or altering an egress or bedroom window usually does. Rules vary because each Arizona city or county adopts its own code edition. Bedroom and basement windows must meet emergency escape and rescue (egress) sizing under whichever residential code edition your jurisdiction adopted. Arizona sets no statewide building code, so verify the local amendments before ordering units. Mesa lets you replace windows with the same or better energy ratings in the same size opening without a permit; changing the opening size or converting a window to a door requires a construction permit. Mesa's FAQ notes sleeping-room (egress) windows must keep a clear opening of at least 5.7 square feet, so verify egress before altering any bedroom window. Homes in a historic designation need Planning Division approval before window or door changes.
