Direct answer

The Monadnock Building, historically recorded as the Monadnock Block, is the landmark office building at 53 West Jackson Boulevard. City and federal records resolve its two major construction halves and architects, while parcel, ownership, loading, access, life-safety and telecom authorization remain unverified.

Canonical identity

This Public Seed preserves the North and South halves and the four historic section names as one historic building graph rather than treating old entrances or systems as current routing. The public building site supports office and leasing functions but does not publish dispatch procedures.

Property typeCommercial office
Management routeThe public building office lists Claudia Daly and Julia Donnell for information and leasing. Neither listing establishes a current manager, security, engineering or operational authorization role.
Ownership claimCurrent legal ownership and taxpayer identity were not verified.

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.

Historic structure

The City identifies the North half as an 1889–91 Burnham & Root load-bearing masonry building and the South half as an 1891–93 Holabird & Roche steel-frame addition.

Questions this record answers

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

01Is the Monadnock Building the same as the Monadnock Block?+

Yes. City and National Park Service records use Monadnock Block for the historic resource at 53 West Jackson, while the current property site uses The Monadnock Building.

02Why are multiple historic sections listed?+

The operator describes four originally separate office sections, and the City distinguishes major North and South construction halves. Historical sections do not prove current entrances, elevators or mechanical routing.

03Who handles building operations?+

The public site lists information and leasing contacts only. Current property management, engineering, security and operational authority remain unknown.

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.
