Milwaukee approves expanded tax-increment financing for 100 East Wisconsin office-to-apartment conversion downtown project

City-backed financing structure revised as redevelopment budget and timing come into focus

Milwaukee has advanced plans to convert the downtown 100 East Wisconsin office tower into a large-scale apartment building, approving a tax incremental financing (TIF) package designed to reimburse project costs over time. The Common Council adopted the resolution creating Tax Incremental District (TID) No. 127 on July 31, 2025, with the mayor signing it on Aug. 5, 2025. The district is effective as of Jan. 1, 2025.

The project centers on 100 E. Wisconsin Ave., a single-parcel TID intended to support the historic rehabilitation and reuse of a largely vacant office building. City documents describe the property as about 75% vacant at the time of planning and projected to be fully vacant by September 2025.

What the project includes

The redevelopment plan calls for 373 residential units, with 75 apartments—20% of the total—designated as workforce housing for households at or below 100% of area median income. Plans place apartment units on upper floors, with resident amenities proposed across multiple levels and enclosed parking on lower floors. A portion of the top floors is planned to remain largely unchanged to meet historic rehabilitation requirements.

The project plan identifies the building as listed on the State and National registers of historic places, a status that can support applications for historic tax credits. The overall development cost described in city materials is approximately $165 million.

How the TIF is structured

Under the adopted project plan, the city’s TIF support is structured as a developer-financed grant reimbursement. The city is authorized to reimburse up to $14.4 million in eligible costs through annual payments equal to 100% of incremental property taxes generated within the TID, minus an annual administrative charge. The reimbursement term is set for up to 16 years, with interest up to 6.2% applied to the outstanding reimbursable amount.

The plan also estimates administrative costs and interest expenses associated with the reimbursement structure. City documents specify that the city may choose to prepay the grant, which could involve issuing public debt backed by tax increment revenues.

Next milestones and oversight

The TID process included a public hearing held July 17, 2025, and approval by the Redevelopment Authority on the same date, followed by Common Council adoption later that month. The approved resolution directs city officials to execute a development agreement and related standard agreements used for TIF-supported projects.

• Project: Conversion of 100 East Wisconsin office tower to 373 apartments
• Workforce set-aside: 75 units (20%) targeted to households up to 100% AMI
• TIF amount: Up to $14.4 million, reimbursed from incremental taxes
• Term: Up to 16 years, interest up to 6.2%

Key question for taxpayers and city finance: whether projected property-value growth within the new district is sufficient to repay the reimbursement obligation within the planned timeframe.
