Direct answer

Onni 200 LaSalle is a 30-story Loop office building at 200 North LaSalle Street. Its first-party site identifies Onni and current Stream Realty leasing contacts, plus a public building endpoint and an authenticated tenant-service portal. None of those surfaces establishes public eligibility, operating rules or dispatch authority.

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 routes

The site publishes (312) 346-1400 and 200n@onni.com; scope, authorization and response authority require confirmation.

Observed August 15, 2026

Tenant service

A Building Engines tenant-login and request-service link exists, but authentication, permissions, workflow and receipt behavior were not tested.

Observed August 15, 2026

Dispatch state

Amenities and portal existence do not supply dock, freight, access, COI, reservation, fee, life-safety or telecom rules.

Questions this record answers

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

01Who owns Onni 200 LaSalle?+

Onni presents the building in current first-party materials, but the exact fee-owner entity and deed were not verified.

02Can tenants submit service requests online?+

A login-protected tenant-service link is published. Only an authorized tenant should use it, and the resulting ticket or provider receipt should be retained.

03Do the amenities establish access or reservation rules?+

No. Amenity descriptions do not define eligibility, credentials, hours, fees, availability or dispatch authority.

04How can I improve this record?+

Submit a current public handbook, dock guide, move rule or COI package and state whether it may be displayed publicly, used only for verification or retained privately. Contributions enter evidence review.
