Do I need a permit for window or exterior door replacement in Wheaton?
Yes. In Illinois, window or exterior door replacement generally requires a permit, and Wheaton is no exception.
Illinois publishes no statewide list of work exempt from a residential building permit. Most Illinois jurisdictions treat a like-for-like window or door replacement in the same opening as exempt, while enlarging or adding an opening triggers a permit and structural (header) review. Confirm the local rule before you order units. Many local codes require bedroom windows to meet emergency escape and rescue (egress) sizing when they are replaced, under whichever residential code edition the jurisdiction has adopted. Wheaton provides a dedicated Window Replacement guideline and requires a permit for window and door work. Replacement windows must meet the adopted energy code and, in bedrooms and basements, the emergency escape and rescue opening (egress) requirements. Creating a new opening or resizing an existing one is a structural change and will require additional plan detail, so mark any size change on your application. Wheaton has adopted the 2024 International Residential Code and the 2024 Illinois Energy Conservation Code with local amendments. Confirm the current window submittal checklist with the Building and Code Department at 630-260-2050. 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.
