155 N Wacker Dr, Chicago, IL 60606
40% provisional source coverage
USE BOUNDARYNot verified · Not dispatch ready
155 North Wacker is one office and retail tower at 155 N Wacker Drive in Chicago. Stream Realty was awarded management and leasing in September 2024, and first-party evidence supports that association through July 2025. Factum has not independently confirmed the assignment as current in August 2026 or found authoritative current dock, freight, move, COI, access, life-safety, telecom or dispatch rules, so the building is Graph Mapped but not Verified or Dispatch Ready.
Canonical identity
This Public Seed resolves the tower, address, one Cook County parcel signal and dated management relationships. It keeps conflicting area and story measures separate, treats registry ownership as a signal rather than title proof, and excludes security-sensitive or unsupported operating instructions.
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 scope
Public sources converge on one office and retail tower at 155 N Wacker Drive. The separately named 151 N Franklin property is not part of this building record.
Sources reviewed August 14, 2026Management transition
John Buck reports management from 2009 through 2024. Stream announced that it was awarded management and leasing on September 5, 2024; later first-party material supports the association through July 2025, not necessarily today.
Assignment announced September 5, 2024; latest public continuity evidence July 9, 2025Parcel signal
Cook County associates the address with PIN 17-09-429-018-0000 and a 25,678-square-foot land parcel. The parcel/account record is not treated as a synonym for the physical building.
Cook County record captured August 14, 2026Current operating rules
No authoritative current public tenant handbook or manager-issued source established access, loading, freight, move, COI, contractor, life-safety, telecom, riser or dispatch procedures.
Public-source review completed August 14, 2026Questions this record answers
Each concise answer includes the same caveats shown elsewhere on the page.
01Is 155 North Wacker one building or a campus?+
It is one office and retail tower. Public evidence names 151 North Franklin as a separate building, so Factum does not merge the two into a campus.
02Who manages and leases 155 North Wacker?+
Stream Realty announced that it was awarded management and leasing in September 2024, and first-party evidence supports its association through July 2025. Factum has not independently confirmed that assignment as current in August 2026.
03Why do sources report different building sizes and story counts?+
The City-derived record reports 1,406,031 square feet, Stream reported 1,152,953 square feet and 46 floors in 2024, and ENR reported 1.38 million square feet and 48 stories in 2009. Factum preserves each source's measure rather than averaging them.
04Are freight, access, move, COI or vendor rules publicly verified?+
No. Factum found no authoritative current public source for dock, freight, move, COI, contractor, access, life-safety, telecom, riser or dispatch procedures.
05How can I help improve this record?+
Use Get early access to submit a correction or tenant/vendor-facing public evidence such as a handbook, dock or freight guide, move rules or COI package. Choose public-display, verification-only or private-retention permission; submissions enter evidence review and never overwrite canonical claims directly.
