Do I need a permit for window or exterior door replacement in Bolingbrook?
Most likely yes. Window or exterior door replacement usually requires a permit in Illinois. Confirm the specifics with Bolingbrook.
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. Bolingbrook publishes door and window modification permit guidance, and changing the size or location of an opening is regulated construction that needs a permit. Effective November 30, 2025, Illinois adopted the 2024 International Energy Conservation Code with state amendments, tightening the window and door U-factor from 0.30 to 0.28, so replacement products must meet the current energy code. All contractors must be currently registered with the Village. Confirm whether your specific replacement needs a permit with the Bolingbrook Building Division before ordering materials.
