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!

@Swetha Solipuram - If you aren't in the ADU pilot area then you need to understand what your building is currently zoned (chicago zoning map website = https://gisapps.chicago.gov/Zo...) and see what you can build buy right.  If it's a legal 2 and you want to make it a legal 3, that is more than likely going to require a zoning change as @Brie Schmidt mentioned but you'll have to double-check the calculations based on your current zoning just to be sure.

Either way, definitely check with an architect like @Samuel Pavlovcik or @Prashanth Mahakali or you can always figure out the calculations yourself - I like this website: https://secondcityzoning.org/
