QUALITY STATE

90% provisional source coverage

USE BOUNDARY

Not verified · Not dispatch ready

Direct answer

55 West Monroe is a Central Loop office tower historically known as the Xerox Center. Its live building site identifies a management team and publishes a JLL-routed COI workflow. A four-PIN Cook County association remains provisional, and the public move, dock and life-safety material is stale. The building is Graph Mapped, not Verified or Dispatch Ready.

Canonical identity

This Public Seed resolves the building identity, preserves the historical owner timeline and current management signals, and keeps conflicting height, floor, year and area measures separate. It does not convert an undated handbook or 2021 rate sheet into current operating authority.

Property typeOffice
Management routeThe current building contact page lists a Senior General Manager, Senior Property Administrator, Chief Engineer, Director of Security and Night Cleaning Supervisor in Suite 950. The tenant-resources page uses a JLL mailbox for COI review.
Ownership claimHearn reports selling the building to John Hancock in September 2014. Current tenant resources name John Hancock, Manulife and JLL interests, but do not establish present legal title.

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 COI workflow

The official tenant-resources page routes COIs to 55westmonroe@jll.com and publishes insurance limits. Submission is not approval; an acceptance or deficiency response is required.

Live page reviewed August 14, 2026

Management roles

The official contact page publishes a management and security roster in Suite 950. The page does not establish legal title or every person's authority for a specific action.

Live page reviewed August 14, 2026

Moves and freight

An undated handbook describes a Dearborn-alley dock, freight car #1 and after-hours move controls. These are stale research leads and must be reconfirmed before scheduling or dispatch.

Undated handbook reviewed August 14, 2026

Parcel scope

A 2024 Cook valuation record associates four PINs with the address. They remain a candidate cluster, not a finalized legal parcel merge.

Questions this record answers

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

01Are the public move and dock rules current?+

No. The detailed handbook is undated and conflicts with newer staff and contact information. Current management confirmation is required.

02Can a COI be submitted publicly?+

The official site publishes a JLL mailbox and insurance requirements, but only an authorized requester should submit and a durable acceptance is required before work.

03Who currently owns the tower?+

A 2014 sale to John Hancock is documented, and current resources name John Hancock and Manulife interests. Present deed title has not been verified.

04How can I improve this record?+

Submit a correction or dated tenant handbook, dock/freight guide, move rule or COI package and choose public-display, verification-only or private-retention permission. Contributions enter review and never overwrite canonical claims directly.
