Missouri lawmakers advance new downtown St. Louis incentive ideas, including office-to-housing tax credits and innovation districts

Proposals target vacant towers, housing demand, and redevelopment financing gaps

Missouri lawmakers are advancing a new round of proposals aimed at accelerating redevelopment in downtown St. Louis, with a focus on converting long-vacant office buildings into housing and creating targeted zones that would unlock tax incentives and streamlined approvals.

The legislative push arrives as downtown St. Louis continues to grapple with large, empty office properties that are costly to rehabilitate and difficult to finance in a market shaped by higher construction costs and interest rates. Supporters of the bills argue the tools are designed to close “financing gaps” that keep large-scale conversions from moving forward, while critics of public incentives generally question whether subsidies shift risk from private developers to taxpayers.

Office-to-residential tax credits: a recurring bipartisan concept

One major pillar is a state tax credit structure designed to encourage office-to-residential or mixed-use conversions in downtowns and main street corridors statewide. Versions of the concept have been debated across multiple sessions, including a 2025 measure that moved through the Missouri Senate but did not become law. The framework has included credits of up to 25% for eligible conversion costs, with enhanced support—up to 30%—for upper-floor housing projects in designated main street districts. Annual caps discussed in prior and current iterations have been set at $50 million per fiscal year, with additional set-asides tied to very large buildings and to main street locations.

Supporters have repeatedly cited downtown St. Louis landmarks, including the Railway Exchange building and the former AT&T tower, as examples of properties whose scale and condition make private redevelopment difficult without public participation.

HB 3231: “Innovation District” concept adds revenue capture and accelerated approvals

A separate proposal introduced in 2026, House Bill 3231—titled the Missouri Innovation, Public Safety, and Accountability Act—would allow a city to designate a single downtown “Innovation District” to access a package of incentives and administrative changes. The plan as described publicly includes a 10-year program window with a sunset provision, a tax credit component for office-to-residential conversion costs, and a mechanism to capture a portion of incremental state tax revenues generated within the district. It also outlines a faster approval process, including a state review timeline that could result in automatic approval if deadlines are not met.

How the policy tools would work in practice

• Tax credits would reduce a project’s effective cost, making conversions more financeable.

• Set-asides would steer a portion of benefits to defined areas and, in some versions, to exceptionally large buildings.

• Innovation-zone structures would pair incentives with procedural changes meant to shorten development timelines.

Across proposals, the central policy rationale remains consistent: using targeted state incentives to catalyze private investment where redevelopment economics do not currently pencil out.

Local context: incentives alongside existing downtown programs and public investment debates

The state-level effort is unfolding alongside local initiatives and ongoing scrutiny of how St. Louis uses incentives. City development entities have continued smaller-scale programs—such as retail grants intended to activate street-level storefronts—while data presented to city officials in recent years has shown a decline in the number of local projects receiving tax incentives compared with prior peaks. Separately, St. Louis leaders have debated allocations of settlement funding and other public resources for downtown and neighborhood priorities, highlighting the broader fiscal and political context surrounding any new subsidy proposals.

The downtown-focused bills remain subject to committee action, amendments, and negotiations before any incentives can be authorized and implemented.
