Do I need a permit for window or exterior door replacement in Unincorporated Champaign County?

Permit may be required

It depends. Whether window or exterior door replacement needs a permit in Unincorporated Champaign County comes down to the details of your project.

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.
