Do I need a permit for window or exterior door replacement in Highland Park?
Yes. In Illinois, window or exterior door replacement generally requires a permit, and Highland Park 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. Highland Park publishes separate requirement sheets for Window Replacement (same size only) and for Window and Door work that changes an opening, which indicates a permit is expected for window and door replacement. Confirm the correct requirement sheet with the Highland Park Building Division. Creating a new opening or enlarging one is structural work that will need drawings and a plat of survey, and egress and safety-glazing rules under the 2024 International Residential Code apply. A straightforward same-size replacement uses the simpler submittal but still follows the permit process. Landmark and historic district properties may require additional review of exterior changes such as windows and doors, so verify with the City before ordering materials. 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.
