20 North Clark Street
20 N Clark St, Chicago, IL 60602
70% provisional source coverage
USE BOUNDARYNot verified · Not dispatch ready
20 North Clark Street is a Loop office building represented in Chicago's 2023 energy-benchmarking data as Building ID 103739. City permit records expose two parcel candidates, but current title and the controlling management relationship were not verified.
Canonical identity
This Public Seed resolves the building identity and preserves parcel, ownership, area, vintage and geometry conflicts. No marketing or leasing contact is treated as authority for access, safety or dispatch.
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.
Public identity
Chicago benchmarking and permit records support the address and office use.
Government records reviewed August 16, 2026Geometry caution
Benchmark and permit coordinates conflict; the benchmark point must not be used for routing.
Conflict retained August 16, 2026Operating rules
No current visitor, loading, move, life-safety, telecom or dispatch procedure was accepted.
Public-source review completed August 16, 2026Questions this record answers
Each concise answer includes the same caveats shown elsewhere on the page.
01Is the current owner or manager verified?+
No. Historical and market-facing relationships do not establish current title or delegated operational authority.
02Can the published coordinates be used for routing?+
No. The benchmark geometry conflicts with address-linked City records and is explicitly excluded from operational use.
03How can I correct or enrich this record?+
Submit an authoritative public link or dated official document and identify whether it may be displayed publicly, used only for verification, or retained privately. Tenant handbooks, dock and freight guidance, move rules and COI packages enter evidence review and never overwrite accepted claims directly.

- 01Current deed holder, beneficial owner, legal parcel boundary and management authority.
- 02Visitor, dock, freight, move, COI, emergency, life-safety and telecom procedures.
- 03Resolution of published area, vintage, class and geometry conflicts.
