Canonical identity

This Public Seed resolves the building and current-facing management and leasing network while preserving conflicts in area, floor-count language and ownership labels. Current permits are retained as scoped work evidence only and do not establish building-wide systems, vendor approval or dispatch rules.

Property typeOffice and retail
Management routeSterling Bay says it assumed property management, asset management and leasing responsibilities effective November 19, 2024.
Ownership claimCurrent legal title is unresolved. A 2026 permit names MW49 123 North Wacker LLC as an owner applicant, which is not treated as deed evidence.

Area claims stay separate

What public guidance supports

These are sourced research answers, not permission to enter, reserve, submit, or dispatch. Current affected-party authorization remains required.

Current management and leasing

Sterling Bay is publicly identified as property manager, asset manager and leasing agent. Published contacts are leasing channels, not operational authorization.

Property and manager pages reviewed August 15, 2026

Current work evidence

City permits describe current tenant alterations, fire-alarm modifications, scaffolding and low-voltage work. Each permit is scoped evidence and does not define building-wide procedures.

Official permit records through August 2026

Dispatch state

No current public dock, freight, move, COI, visitor, emergency or riser procedure qualified for dispatch.

Questions this record answers

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

01Who manages 123 North Wacker?+

Sterling Bay says it has handled property management, asset management and leasing since November 19, 2024. A leasing contact is not authority for access or vendor work.

02Who owns the building?+

Current recorded title was not verified. Permit applicant labels and transaction reporting remain candidates, not legal-title proof.

03Do current permits reveal the building's operating rules?+

No. They support specific project scopes only and cannot establish building-wide fire-alarm, access, vendor or telecom procedures.

04How 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.
