Each Building Permit Application must include construction plans and documents that indicate the location on a Plat of Survey, nature and extent of the work in sufficient detail to verify it will comply with the applicable codes and regulations. These plans and documents must be prepared and certified by an Illinois State licensed architect or structural engineer, except when the project does not include structural or significant life safety work as determined by the Building Official.

The type and quantity of submittals required for some typical projects are listed on the Minimum Plan Review Submission Requirements (see page 2 of the Building Permit Application (PDF), and submittal procedures are further explained on the Project Submission Procedures (PDF). These forms are only intended as a guide for the initial application submittal. Additional submittals, if any, will be identified upon the first plan review.
