Do I need a permit for window or exterior door replacement in Mundelein?
Most likely yes. Window or exterior door replacement usually requires a permit in Illinois. Confirm the specifics with Mundelein.
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. Replacing windows or exterior doors in Mundelein generally requires a permit, and changing the size of an opening or adding a new window or door is treated as more involved work. Confirm whether your specific like-for-like swap needs a permit with the Building Department at 847-949-3283. Windows and doors must still meet the Village-adopted Residential Code, including egress and safety-glazing rules, whether or not a permit is required, so keep the manufacturer's specifications with your paperwork. Any contractor performing the work must be registered with the Village before a permit is issued, and applications are filed through the BS&A Online portal. 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.
