01

Canonical identity

This Public Seed separates the physical building from a census-supplied LLC label and separates reported investment control, property management and legal title. It publishes the source conflict visibly and makes no access, safety or dispatch inference.

Property typeOffice
Management routeJanuary 2026 reporting and the current building contact page support Hines as property manager; no ownership, asset-management or action authority is implied.
Ownership claimCurrent recorded legal title is unknown. January 2026 reporting supports qualified source-reported investment control by a Nuveen/PCCP venture, whose exact legal vehicle is not established.
LocationNot independently verified
02

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.

Reported building area922,580 sq ftCurrent Hines property-page figure; an older Hines source reports 896,502 square feet, so measurement reconciliation remains open
03

What public guidance supports

These are sourced research answers, not permission to enter, reserve, submit, or dispatch. Current affected-party authorization remains required.

Physical description

Hines describes the office building as completed in 1987 with 35 floors and 922,580 square feet. The area is retained as source-reported because older Hines material differs.

Current Hines property page reviewed August 17, 2026

Control and management

January 2026 reporting says a Nuveen/PCCP venture took investment control through a mezzanine-to-equity conversion and Hines retained property management. These are role-limited reports, not deed evidence.

Identity separation

The census label 321 N. Clark Property, LLC is preserved as source-native text only. It is not merged with the building, Nuveen, PCCP, Hines or a titleholder.
