USE BOUNDARYNot verified · Not dispatch ready
200 West Jackson Boulevard is a Loop office building whose current property site identifies Jones Lang LaSalle Midwest with leasing and property-management presentation and names Song Stoller as a management contact. Current ownership, parcel identity and public access, loading, vendor, life-safety and telecom procedures remain unverified.
Canonical identity
This Public Seed resolves the building and current-facing JLL contact network while keeping historic ownership reports and 28-versus-29-story, 1970-versus-1971 and area conflicts explicit. The property app and a carrier directory listing are not treated as access or telecom authorization.
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-facing management
The property contact page lists Song Stoller under property management and JLL Midwest in its leasing and property-management presentation. Exact authority and effective dates are not public.
Current property pages reviewed August 15, 2026Telecom candidate
Cogent includes the address in a connected-office-building directory. That does not prove serviceability, demarc access, riser rights or building authorization.
Carrier directory observed August 2026Dispatch state
No current public dock, freight, move, visitor, COI, emergency or riser procedure qualified for dispatch.
Public-source review completed August 15, 2026Questions this record answers
Each concise answer includes the same caveats shown elsewhere on the page.
01Who manages 200 West Jackson Boulevard?+
The current property site presents JLL Midwest for leasing and property management and lists Song Stoller as a management contact. The public page does not define the contact's authority for operational actions.
02Who owns the building?+
Current legal title was not verified. Historical sources identify White Oak and Angelo Gordon in 2015 and report a Nightingale acquisition in 2022.
03Does Cogent's directory prove telecom access?+
No. It is a provider-location signal only and does not establish serviceability, demarc, riser access or authorization.
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.
