Applications for licensing are managed by your local city or county government jurisdiction. Those agencies determine which ICC exam is appropriate for your license based on local code adoption.
To find the details of the sub-categories listed, you must use the ICC web page (from the button below) and search for your exam by choosing "Type: Contractor/Trades" and "State: National/All". Then enter the three digit exam code in the "Title" (e.g., T16). Click "Search" then "Outline".
