The Chicago Cubs’ renovation project at Wrigley Field is being investigated by federal authorities to determine whether the work provides disabled fans with the necessary level of access on game days.

The Associated Press news agency notes that the Cubs have filed a notice of the review in the Chicago federal court. The team has previously moved to improve disabled access at Wrigley Field following a federal lawsuit that claimed previous work reduced the number of wheelchair-accessible seats.

The Chicago Sun Times newspaper has reported that lawyers for the team last week filed a letter with US District Judge Jorge Alonso disclosing the investigation, which seeks to determine whether the work is in line with the Americans with Disabilities Act.

The team believes the level of accessibility has “significantly increased” following the renovation work. However, the Cubs are putting plans to install more accessible seating on hold while the authorities’ investigation is carried out.

Wrigley Field has a capacity of 41,000 and has been the Cubs’ home since 1916. Renovation work has been taking place at the stadium since 2014.
