USE BOUNDARYNot verified · Not dispatch ready
151 North Franklin, also known as CNA Center, is a 2018 office tower at 151 N Franklin Street. Stream Realty Partners announced in September 2024 that it had been awarded leasing and management. The assignment also covered the separate 155 N Wacker building, but Factum does not merge their operations. This building is Graph Mapped, not Verified or Dispatch Ready.
Canonical identity
This Public Seed resolves the identity and separates 151 N Franklin from adjacent 155 N Wacker. It preserves the dated Stream relationship, historical John Buck and engineering evidence, parcel uncertainty and all current operating unknowns.
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.
Building boundary
151 N Franklin and 155 N Wacker are separate buildings. A joint Stream assignment does not imply shared docks, security, service desks or authorization.
Dated Stream announcement September 5, 2024Management
Stream was awarded management and leasing in September 2024. The assignment's end date and current building-management route remain unknown.

Public-source review completed August 14, 2026Questions this record answers
Each concise answer includes the same caveats shown elsewhere on the page.
01Is CNA Center the same building as 151 North Franklin?+
Yes. Public industry evidence treats CNA Center as another name for the same building at 151 N Franklin Street.
02Does it share operations with 155 N Wacker?+
No shared operating relationship is established. The buildings received a joint management and leasing announcement but remain separate identities.
03Are current visitor, freight or life-safety procedures known?+
No. Historical design evidence cannot be used as a current operating or dispatch procedure.
04How can I improve this record?+
Submit current manager confirmation, a county parcel record, or a dated handbook, dock/freight, visitor, emergency or riser package and choose public-display, verification-only or private-retention permission.
