Purchasing properties with "illegal" units
Would you purchase a property in Chicago with a non-conforming or illegal unit? What are your exit strategies if an issue comes up? What are the insurance or legal risks? Would you purchase the property valuing it with the additional income or value it by its legal status? Let's assume that the ADU ordinance will not apply to you.

@Jonathan Satizabal - this is why there are so many of them, they are grandfathered in
13-196-740 One additional dwelling unit over original allowed – Conditions. A pre-ordinance (built before July 8, 1957) residential building or building of mixed residential occupancy, not complying with the requirements in force and applicable to the building at the time of its conversion, may be altered so as to legalize one dwelling unit, in addition to the number of dwelling units originally authorized, providing that said unit was determined by the office of the zoning administrator or the zoning board of appeals to have existed prior to July 8, 1957, and provided such building complies with the other provisions of this chapter.
