Canonical identity

This Public Seed keeps the physical building, parcel, regulatory-facility owner label, reported acquisition partners and property manager roles distinct. It publishes source-qualified acquisition evidence while withholding an unverified title owner and conflicting floor count.

Property typeOffice
Management routeGlenstar is reported to have assumed asset and property management in June 2026; the legal scope and current authority require confirmation.
Ownership claimCurrent legal owner is not established. The OSFM facility record and June 2026 acquisition sources are shown only within their own scope.

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.

Questions this record answers

Each concise answer includes the same caveats shown elsewhere on the page.

01What is 500 West Monroe?+

It is an office tower at 500 W Monroe St in Chicago, historically also called Heller International Tower.

02Who owns 500 West Monroe?+

The current legal owner was not established. A state regulatory record names 500 West Monroe Owner, LLC for its facility scope, while Glenstar publicly describes a June 2026 acquisition and portfolio association.

03How many stories does 500 West Monroe have?+

Public sources conflict: some say 44 stories, two trade reports say 46, and CTBUH/CVU records 45 floors above ground under its own method. Factum does not normalize those values.

04Can this record be used for access or dispatch?+

No. Current loading, visitor, freight, safety and telecom-riser rules were not established, and public contacts or acquisition reporting do not create action authority.

05How can I correct or enrich this record?+

Submit an authoritative public URL or dated official document, identify the exact field and effective date, and choose public-display, verification-only or private-retention permission. Contributions enter evidence review and never overwrite canonical claims directly.
