50% provisional source coverage
USE BOUNDARYNot verified · Not dispatch ready
311 South Wacker Drive is a single 65-story Chicago office tower. Current public evidence supports a June 2025 purchase by Kohan Retail Investment Group and a current JLL sublease channel, but not recorded title, a current property manager, or current operating rules. The record is Graph Mapped, not Verified or Dispatch Ready.
Canonical identity
Factum mapped the building identity and current public relationships while preserving the post-acquisition evidence boundary. A March 2025 Zeller-era handbook remains historical evidence and is not presented as current operating guidance.
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 public relationship
JLL publishes an active sublease listing and named listing contacts. That supports the advertised sublease only, not building management or owner authority.
Listing reviewed August 16, 2026Operating guidance
No current public source established property management, access, dock, freight, move, COI, life-safety or telecom rules.
Reviewed August 16, 2026Questions this record answers
Each concise answer includes the same caveats shown elsewhere on the page.
01Who owns 311 South Wacker Drive?+
Trade reporting says Kohan Retail Investment Group completed the purchase in June 2025. Recorded title and the legal owning entity still require Cook County confirmation.
02Can the public leasing contacts authorize building access or work?+
No such authority is established. Written approval from a verified owner or authorized current manager, with a durable receipt, is required before any building-state action.
03How can I correct or enrich this record?+
Submit public links, current handbooks, dock or freight guidance, move rules, COI packages or corrections for evidence review, and state whether the material may be displayed publicly, used only for verification or retained privately.
