80% provisional source coverage
USE BOUNDARYNot verified · Not dispatch ready
353 North Clark is a 45-story office and retail building in Chicago's River North area that opened in 2009. The official building site publishes CBRE property-management and leasing contacts. A 2025 Cook County assessor record provides a PIN and taxpayer name, but Factum does not treat that as proof of current title or a building-parcel identity. The building is Graph Mapped, not Verified or Dispatch Ready.
Canonical identity
This Public Seed resolves the building while keeping the Planned Development, adjacent 321 North Clark, Westin Hotel, tax parcel, taxpayer, title entity and tenants separate. Conflicting sustainability labels and missing operating procedures remain visible.
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.
Property-management route
The official contact page publishes CBRE management roles and phone/email channels, but a public listing does not authorize work, access or commitments.
Undated page reviewed August 16, 2026Parcel candidate
The 2025 assessor result for PIN 17-09-408-015-0000 names HART 353 N CLARK LLC as taxpayer and displays a 353 N Clark mailing address. Taxpayer, owner, parcel and building remain distinct claims.
Tax year 2025 record reviewed August 16, 2026Operating rules
No current authoritative public package established dock, freight, move, COI, access, life-safety, emergency or telecom-riser procedures.
Public-source review completed August 16, 2026Questions this record answers
Each concise answer includes the same caveats shown elsewhere on the page.
01What is 353 North Clark?+
It is a 45-story office and retail building in Chicago that the official site says opened in 2009.
02Who manages 353 North Clark?+
The official building contact page lists CBRE property-management roles, but those role listings require current confirmation before operational use.
03Does the Cook County PIN prove who owns the building?+
No. The assessor page supplies a parcel candidate and taxpayer name; it does not by itself prove current record title or that the parcel is coterminous with the building.
04How can I correct or enrich this record?+
Submit an authoritative public URL or dated official document, identify the exact field and effective date, and choose public-display, verification-only or private-retention permission. Submissions enter evidence review and never overwrite canonical claims directly.
