60% provisional source coverage
USE BOUNDARYNot verified · Not dispatch ready
20 South Clark, also known as Two First National Plaza, is a Central Loop office building. Ravelin publishes the current property-management and leasing route, while City records show a bounded 2026 fire-alarm modification; neither source supplies building-wide access, delivery, emergency or dispatch rules.
Canonical identity
This Public Seed resolves one office building and its current-facing management relationships. It preserves conflicts in year, story count, architecture and area, and treats the City permit as an event record rather than a safety certification.
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.
Management route
Ravelin says it internalized Chicago property management and accounting effective June 1, 2025 and publishes current property-management and leasing roles. Public roles do not authorize a specific request.
Company release dated May 12, 2025; roles reviewed August 16, 2026Bounded life-safety evidence
City permit B200471574 was issued June 8, 2026 and is listed Active/Inspections for an alarm-system modification on levels 24 and 25. It is not a building-wide emergency procedure, condition audit or action permission.
City permit record captured August 16, 2026Dispatch state
A tenant-portal link and leasing contact exist, but authentication, permission scope, access, dock, move, COI and telecom workflows remain unknown.
Research reviewed August 16, 2026Questions this record answers
Each concise answer includes the same caveats shown elsewhere on the page.
01Who manages 20 South Clark?+
Ravelin's current property page lists Martha Green as VP Property Management and Jessie Hoffman as Property Manager. Their current authority for any specific request must be confirmed.
02What does the 2026 fire-alarm permit prove?+
Only that City records show an active alarm-system modification at levels 24 and 25. It does not prove building-wide safety condition or provide emergency instructions.
03Is this record dispatch ready?+
No. Access, loading, move, COI, emergency and telecom procedures have not been sourced or audited.
04How can I improve this record?+
