Direct answer

300 South Wacker is a 35-story Loop office building. Cushman & Wakefield reported in September 2024 that Deutsche Bank selected it for leasing and Tishman Speyer for property, asset and hospitality management; the current property site names Lori Brudzisz for management and Mason Taylor and Paige Krueger for leasing. Current legal title, parcel identity and operating rules remain unverified.

Canonical identity

This Public Seed resolves a working physical asset and current-facing management and leasing network. It preserves the ownership-entity and area conflicts, keeps a permit lead unpromoted, and excludes historic security, elevator and telecom claims from current operating guidance.

Property typeOffice
Management routeTishman Speyer was selected in 2024 for property, asset and hospitality management; the current site names Lori Brudzisz as management contact.
Ownership claimCurrent legal title is unresolved. The census owner label and historic AG 300 South Wacker Owner LLC evidence conflict with a 2024 report identifying Deutsche Bank as investor.

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.

Current-facing management

The property site names Lori Brudzisz for management information. The public contact is not evidence of authority for access, vendor work or dispatch.

Property page reviewed August 15, 2026

Leasing and service relationships

Cushman & Wakefield reported a September 2024 leasing assignment and Tishman Speyer management assignment; the current site still lists the named leasing and management contacts.

2024 assignment corroborated by current property page

Dispatch state

Parking, amenities and historic security or elevator descriptions do not disclose current dock, freight, visitor, life-safety or telecom procedures.

Questions this record answers

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

01Who manages 300 South Wacker?+

Tishman Speyer was selected in 2024 for management services, and the current property site names Lori Brudzisz as the management contact. Authority for any operational action remains unverified.

02Who owns the building?+

Current legal title is unresolved. Public entity and investor evidence is not sufficient to identify a current deed owner.

03Does a public permit prove active project work?+

No. The cited permit lead lacks an audited official scope, applicant and address record and is not treated as a live opportunity.

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.
