Do I need a permit for window or exterior door replacement in Joliet?
Most likely yes. Window or exterior door replacement usually requires a permit in Illinois. Confirm the specifics with Joliet.
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. Joliet lists roofing, siding, and windows among the residential work that requires a permit and provides a single Roof/Siding/Windows permit application, so window replacement is filed on that form. Exterior doors are not called out separately, but the adopted 2015 International Residential Code governs alterations, egress, and safety glazing, so resizing an opening or changing a window or door can require review. Confirm your specific scope with the Building Division at 815-724-4070. Submit the completed application and documents to permitapplication@joliet.gov or the City Hall drop box (there is no online portal), where the permit fee starts at $65 for up to $7,000 of work. 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.
