A little known (and controversial) city of Chicago ordinance requires that association records be provided to unit owners within 3 days of a written request.
The exact wording of the ordinance is as follows:
No person shall fail to allow unit owners to inspect the financial books and records of the condominium association within three business days of the time written request for examination of the records is received. (Prior code 100.2-8)
Because the ordinance is not in alignment with the IL Condo Act (which sets a 30-day deadline), there have been court cases disputing the validity of the ordinance. However, courts have found in favor of owners seeking documents under the Chicago ordinance.
The IL Condo Act specifies the documents that can be examined. Note that the association must allow for the inspection of the documents, but is not required to provide copies at the association's expense.
