Do I need a permit for window or exterior door replacement in Arvada?
It depends. Whether window or exterior door replacement needs a permit in Arvada comes down to the details of your project.
Arvada lists window and siding installation among the work that generally requires a building permit, and cutting a new opening, enlarging one, or changing a bedroom egress window clearly triggers a permit, so confirm your specific scope with Arvada Building Services. Arvada enforces the 2024 International Residential Code and International Energy Conservation Code (effective January 1, 2026), so bedroom and basement sleeping rooms must keep a compliant emergency escape and rescue opening and new glazing must meet energy requirements. Permit applications and payments run through the Arvada Permits (eTRAKiT) portal at arvadapermits.org. 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. Enlarging an opening, moving it, or cutting a new one is structural work. Exemptions that cover replacing a unit in its existing opening do not reach it, so a permit is required. Changing an opening usually means a new or resized header, and many jurisdictions want a beam detail or engineering before they will issue, so allow for that in the schedule.
