Several years ago, the Cubs were sued by a fan who uses a wheelchair for mobility. The complaint, which you can read here, alleged that the Cubs didn’t have enough accessible seating and that in some areas, they had reduced the amount of accessible seating for various group areas.
The conclusion reached in that lawsuit, in 2019, was as follows:
For the aforementioned reasons, defendant’s motion to dismiss or, in the alternative, to stay is granted in part and denied in part. As for Cerda’s ADA claims, he may proceed with his challenge to the number of Accessible Seats and horizontal dispersion for Accessible Seats at Wrigley Field; he may not proceed with his challenge to Accessible Seating in club/luxury box locations or vertical dispersion.
