USE BOUNDARYNot verified · Not dispatch ready
Congress Center is an office building at 525 W Van Buren St in Chicago, linked to City benchmark ID 100730 and Cook County Assessor PIN 17-16-129-087-0000. Current property-site attribution and a reported November 2025 sale do not establish present recorded title. It is Graph Mapped, not Verified or Dispatch Ready.
Canonical identity
This Public Seed maps Congress Center to its assessor and source-scoped Chicago benchmark identity while preserving the unresolved ownership transition and keeping public leasing channels separate from operating authority.
Area claims stay separate
Gross, rentable, and office area are not interchangeable. Factum stores each measurement with its source meaning instead of choosing a convenient single number.
What public guidance supports
These are sourced research answers, not permission to enter, reserve, submit, or dispatch. Current affected-party authorization remains required.
Parcel identity
Cook County Assessor associates PIN 17-16-129-087-0000 with the address. The assessor location is not treated as recorded title or a legal mailing-address certification.
