Quick Answer
- Hearing held: the City of Justin held a public hearing on October 8, 2026 to consider creating a roughly 1,244.347-acre tax increment reinvestment zone (TIRZ) inside city limits, with the public notice posted September 25, 2026 and affected property owners allowed to protest inclusion.
- Not yet adopted: as of mid-October 2026, creation of the new zone had not been confirmed; it is a consideration-stage item, distinct from the town's existing TIRZ #1 created December 14, 2023 (about 702.78 acres).
- What a TIRZ does: under Texas Tax Code Chapter 311, the incremental increase in tax value generated by development within the zone is captured to fund public infrastructure in the zone, such as roads, water, sewer and drainage; a TIRZ does not by itself change the tax rate anyone pays.
- Reported context: Cross Timbers Gazette reported in March 2026 that a roughly 1,200-acre planned development on Justin's west side, reported to include a grocery store, hundreds of acres of parkland and about 4,865 proposed lots, is in early planning; these are reported project details, not approved plans.
- For buyers: the west side of Justin along FM 407 is the area to track. The zone signals large-scale future development and infrastructure planning, and any new homes would come after the zone and development approvals, years out.
Theresa De La Rosa's Broker Perspective
I'm Theresa De La Rosa, Broker of Covenant Heritage Realty in Northlake. When a client hears that a town is creating a reinvestment zone, the common reactions are either "my taxes will go up" or "I should buy now before the area booms," and neither is quite right. A TIRZ captures the growth in tax value from future development to pay for infrastructure; it is not a tax increase on its own, and it is not a sign that thousands of homes will appear next year. The realistic read is that Justin is doing the infrastructure planning for a large future development on its west side, and that is a multi-year story. My advice is to keep the status honest: a public hearing is not adoption, reported plans are not approved plans, and any purchase decision should rest on what exists today, verified by address, not on a development that is still in early planning.
What the October 8 Public Hearing Considered
The City of Justin held a public hearing on October 8, 2026 at 4:30 p.m. at Justin City Hall to consider creating a tax increment reinvestment zone of roughly 1,244.347 acres inside city limits. The public notice, posted September 25, 2026, advised that affected property owners could protest the inclusion of their property in the zone and learn about tax increment financing. Agendas, packets and minutes for Justin's council are published through the city's agenda portal.
This proposed zone is distinct from the town's existing TIRZ #1, which the City Council created on December 14, 2023, covering roughly 702.78 acres on the south side of FM 407. As of mid-October 2026, creation of the new, larger zone had not been confirmed, so it is accurate to describe the item as at the hearing and consideration stage rather than adopted.
How a Tax Increment Reinvestment Zone Works
A TIRZ is a financing tool created under Chapter 311 of the Texas Tax Code. When a zone is created, the property-tax revenue generated by the increment, the growth in taxable value produced by new development within the zone, is captured and used to fund public improvements inside the zone, such as roads, water, sewer and drainage. Existing tax revenue continues to go to the taxing entities as it always has; only the incremental growth is redirected, usually for a set period.
The practical point for a homeowner or buyer: a TIRZ does not, by itself, raise the property-tax rate anyone pays. It does not add a separate line to a tax bill the way a special assessment or an additional ad valorem rate can. It changes how the tax value generated by future development is directed, which is why it is often the financing structure that makes a large master-planned development's infrastructure possible. For how ownership costs and special districts work in this corridor, the property-tax and ownership-cost guide and the HOA, PID and MUD article cover the related concepts.
What Is Reported About Justin's West Side
The zone on Justin's west side lines up with a proposed large planned development reported by the Cross Timbers Gazette in March 2026. That reporting described a roughly 1,200-acre development along FM 407 on the west side of Justin, northwest of the Treeline community, reported to include a grocery store, hundreds of acres of parkland and about 4,865 proposed lots. These are reported project details from early planning, not approved plans, and the developer and final scope should be confirmed with the City before relying on any of them.
For context, Justin's existing communities anchor the same corridor: Treeline by Hillwood sits on the east side of the area and is already in active phases, and the town's other communities are covered in the Justin relocation guide. A future west-side development would add to the town's housing stock, but only if and when the zone is created and the development is approved, platted and built, a process that takes years.
What It Means for Buyers and Property Owners
For buyers, the reinvestment zone is a signal about Justin's future, not a change to today's market. A TIRZ on the west side indicates the city is working to make a large future development feasible, and it is a reason to track the city's agenda portal for the adoption vote and the development approvals that would follow. It is not, on its own, a reason to buy or wait: any new homes would come years after the zone and development approvals, and a public hearing is not adoption.
For property owners inside the proposed zone, the hearing notice allowed affected owners to protest inclusion, and the notice is the first place to confirm whether a specific tract is included and what the protest process is. For buyers comparing Justin against nearby towns, the practical comparison remains the same as always: exact address, schools, taxes and ownership costs, new-construction versus resale, and commute, which the Justin vs Northlake comparison and the 407 Corridor guide lay out.
Frequently Asked Questions
What is a tax increment reinvestment zone (TIRZ)?
A TIRZ is a financing tool created under Chapter 311 of the Texas Tax Code. When a zone is created, the growth in taxable value produced by new development within the zone is captured and used to fund public infrastructure in the zone, such as roads, water, sewer and drainage. It does not by itself change the tax rate anyone pays.
Has Justin adopted the new 1,244-acre zone?
Not confirmed as of mid-October 2026. Justin held a public hearing on October 8, 2026 to consider creating the roughly 1,244.347-acre zone, and as of the source review date creation of the new zone had not been confirmed. A public hearing is not adoption; track the city's agenda portal for the council vote.
What is planned for Justin's west side?
Cross Timbers Gazette reported in March 2026 that a roughly 1,200-acre planned development along FM 407 on Justin's west side, reported to include a grocery store, hundreds of acres of parkland and about 4,865 proposed lots, is in early planning. These are reported project details, not approved plans; confirm the developer and final scope with the City.
Does a TIRZ raise my property taxes?
Not by itself. A TIRZ captures the growth in tax value from future development within the zone and directs it to infrastructure; it does not add a separate charge to a tax bill the way a special assessment can, and it does not change the tax rate anyone pays. Tax treatment is always property-specific, so verify the exact taxes for any property.
How is a TIRZ different from a PID or MUD?
A TIRZ captures the incremental tax value from new development to fund infrastructure within the zone. A PID is a special assessment that appears on the tax bill, often used for specific improvements and sometimes prepayable, and a MUD is a special district with its own ad valorem tax rate. They are separate mechanisms with separate billing, and a property can be in one, more than one, or none of them; verify by exact address.
Conclusion
Justin's proposed 1,244-acre reinvestment zone on the west side is a real, verifiable city item, but it is at the hearing and consideration stage, not adopted. The October 8, 2026 public hearing and the reported context of a large west-side planned development signal long-term growth planning along FM 407, and any new homes would come years after the zone and development approvals.
The takeaway for buyers and property owners is to keep the status honest: a TIRZ does not raise anyone's tax rate by itself, reported plans are not approved plans, and decisions about where to buy should rest on what exists today, verified by exact address.

Editorial verification note. Sources reviewed October 20, 2026. That Justin held a public hearing on October 8, 2026 to consider creating a roughly 1,244.347-acre tax increment reinvestment zone inside city limits, with a notice posted September 25, 2026 and protest rights for affected property owners, is from the City's public hearing notice. That creation of the new zone had not been confirmed as of mid-October 2026 is a conclusion from the absence of an adoption record in the sources reviewed; the city's existing TIRZ #1 (about 702.78 acres, created December 14, 2023) is from the City's TIRZ page. The description of a TIRZ under Texas Tax Code Chapter 311 is general statutory background. The reported west-side development details (roughly 1,200 acres along FM 407, reported grocery store, parkland and about 4,865 proposed lots, in early planning) come from Cross Timbers Gazette (March 16, 2026) and are reported, not approved, plans; the developer and final scope should be confirmed with the City of Justin before relying on any of them.
