Legalizing Attic Unit Chicago

[Swetha Solipuram]

Hello, I have a 2 legal unit building in Chicago. I am looking for information on how I can legalize the attic unit. It has two exits and plenty of height. When I google information, it is flooded with ADU info, but my building does not fall under the qualifying area. Any information on how I can approach this here in Chicago, would be extremely helpful. Thank you!
