Northern Trust Company Building
50 S LaSalle St, Chicago, IL 60603
20% provisional source coverage
USE BOUNDARYNot verified · Not dispatch ready
The Northern Trust Company Building at 50 South LaSalle is Northern Trust Corporation's principal executive office and is described in its fiscal-2025 SEC filing as Bank-owned. Northern Trust also leases an unnamed adjacent office building, so the executive-office relationship does not define a shared campus or transfer operating rules across buildings.
Canonical identity
This Public Seed corrects the census title typo and distinguishes the Bank-owned 50 South LaSalle building from Northern Trust's separate adjacent leased space. Public banking hours and the corporate switchboard are not building-access, move or dispatch instructions.
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.

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

Submit a current public building guide, dock/freight notice, move rule or COI package and choose public-display, verification-only or private-retention permission. Contributions enter evidence review.
