USE BOUNDARYNot verified · Not dispatch ready
125 South Wacker is a 31-story Loop office tower currently presented by its property site as owned by Menashe Properties and managed and leased by Stream Realty Partners. Current sources disagree on area, and the publicly available tenant handbook names superseded Hines and Ivanhoé roles, so its operating rules are treated as historical rather than current.
Canonical identity
This Public Seed resolves a working building identity, current owner-manager relationships, public role contacts and City benchmark geography. It keeps three area figures visible, withholds parcel identity, and does not promote marketing system descriptions or a legacy handbook into current dispatch rules.
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.
Current relationships
Menashe Properties owns the building and Stream Realty Partners manages and leases it under a November 2025 first-party assignment.
Current property site and November 3, 2025 assignment; reviewed August 15, 2026Published role contacts
The current site lists Anne Schmeissing for property management and Mark Bâby and Ben Cleveland for leasing. These are inquiry routes, not dispatch or emergency authority.
Current property site captured August 15, 2026Operating-rule boundary
The available handbook names legacy Hines and Ivanhoé roles. Its dock, freight, move, COI and access instructions are historical candidates until current management confirms them.
Conflict reviewed August 15, 2026Questions this record answers
Each concise answer includes the same caveats shown elsewhere on the page.
01Who owns and manages 125 South Wacker?+
Current first-party sources identify Menashe Properties as owner and Stream Realty Partners as property manager and leasing provider.
02Are the public tenant-handbook rules current?+
Not established. The handbook names superseded owner-manager roles, so its operating instructions are not treated as current or dispatch-ready.
03How can I improve this record?+
Submit a current public handbook, dock guide, move rule or COI package and state whether it may be displayed publicly, used only for verification or retained privately. Contributions enter evidence review.
