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

Permit likely required

Most likely yes. Window or exterior door replacement usually requires a permit in Colorado. Confirm the specifics with Centennial.

Simple like-for-like replacement may not need a permit in some Colorado jurisdictions, but cutting a new opening, enlarging one, or altering a bedroom egress window usually does. Rules vary because each city or county adopts its own code edition. Bedroom and basement sleeping-room windows must meet emergency escape and rescue (egress) sizing under whichever residential code edition your jurisdiction adopted. Colorado sets no statewide edition, so verify the local requirement before ordering units. Centennial permits window and door work through the Centennial Self-Service (CSS) portal, and cutting a new opening, enlarging one, or changing a bedroom egress window clearly triggers a permit, so confirm your specific scope with the Building Division. New residential windows must meet Centennial's energy amendment of a 0.30 maximum U-factor, so verify the rating before you order. Any bedroom or basement sleeping room must keep a compliant emergency escape and rescue opening under the 2021 IRC that Centennial enforces.
