City staff briefs council on how Houston's tax increment reinvestment zones work and the risks of termination

Director Tillotson Bell gave the Economic Development Committee an extended overview of Houston's tax increment reinvestment zone (TIRZ) program, describing how the program is structured, the legal limits that constrain it and the fiscal consequences of terminating zones while the city is operating in a collections-exceed-cap environment.

Bell said “TIRZ stands for Tax increment reinvestment zone” and repeatedly emphasized that private investment drives the increment revenue that funds projects inside a zone. She told the committee the program is governed by state law and local rules: “Everything that we do regarding the TIRZs is governed by state statute Chapter 311,” and the city adopted a local ordinance and administrative procedures in 2023 to implement the program.

The director explained how a TIRZ captures the increase in property tax revenue attributable to new private investment inside a boundary and channels that increment back into the zone during the board'defined life of the TIRZ. She said typical TIRZ terms are set at creation (commonly 30 years) and that life extensions are used when long-term bonding is required to finance large infrastructure projects. Bell noted some TIRZs have been extended and a longest-life example could last about 58 years under current practice.

Why it matters: Bell warned that terminating TIRZs while the city is in a collections-exceed-cap environment would have lasting fiscal effects. She walked the committee through the revenue-cap math and said that because the city has reduced the property tax rate each year since 2015, the city has returned about $2,200,000,000 to property taxpayers since then. In outline, she said subtracting TIRZ increment from the city'wide collections lowers the adjusted collections number the state compares to the cap and can reduce the amount the city must return as a tax-rate reduction. She also cautioned that termination would remove revenue from other jurisdictions that participate in a zone, create gaps for ongoing infrastructure projects, and could transfer outstanding TIRZ debt obligations to the city.

Bell described statutory creation criteria and petition rules, explaining that a TIRZ may be created where an area is ''substantially blighted'' but that petitioned TIRZs (those created by property owner petition) may be authorized without meeting the slum/deterioration requirement: “A TIRZ that is petitioned by 50% of the property owners within a zone may allow for the creation of a TIRZ,” she said, and used Uptown and Midtown as examples of petitioned zones. She also reviewed statutory limits: no more than 30% of a TIRZ boundary's taxable property value may be residential (defined as 4 or fewer units), the city as a whole must stay under a 25% cap on aggregated TIRZ taxable value (Bell said Houston is near that cap at about 23%), and petition zones must allocate at least one-third of certain revenues to affordable housing.

Council members asked technical and policy questions during a brief Q&A after the presentation. Council Member Alcorn asked whether petitioned TIRZs must meet the other statutory criteria; Bell answered that the statutory criteria are read as alternatives (the statute sets out multiple bases, connected with "or"). Council Member Carter asked whether any TIRZs have zero revenue; Bell said none have zero revenue because land still appreciates, though some older zones (for example, Fifth Ward, Old Sixth Ward, Leland Woods) have produced only modest amounts in some years compared with larger zones that generate millions. Council Member Thomas requested removal of the word ''slum'' from external materials used to describe neighborhoods when possible; Bell said that statutory language remains in Chapter 311 but she and staff could discuss alternative public wording.

A former TIRZ board chair, Theodore Andrews, spoke during the public comment portion. Andrews, who said he chaired TIRZ 25 for more than 10 years, urged community participation in TIRZ boards and framed the program as a way to empower local leaders to steer investment and infrastructure within their neighborhoods.

What's next: Bell said administration staff is reviewing the 2023 ordinance and related administrative procedures for possible amendments to align policy and implementation with the mayor's priorities. She also said staff is evaluating a 'pre-termination' status for zones identified for eventual termination that would prohibit new capital projects and use increment to pay down outstanding debt as a pathway to fiscally responsible wind-downs.

Ending: Council members and staff said they would follow up with written questions; no formal votes or policy changes were taken at the committee meeting.
