SB 840: What Happens When Texas Tells 19 Cities They No Longer Control Where Apartments Get Built

In Texas land use, the relationship between state government and municipal governments has long operated on an informal understanding: cities zone their land, and Austin largely stays out of it. That understanding has been quietly fraying for years — through legislative debates over annexation authority, extraterritorial jurisdiction, and municipal regulatory power. In 2025, it broke openly.

Senate Bill 840, passed by the 89th Texas Legislature on May 21, 2025, signed by Governor Abbott on June 20, 2025, and effective September 1, 2025, represents the most significant state preemption of local zoning authority in Texas history. It tells 19 major Texas cities — including Dallas, Fort Worth, Arlington, Plano, Frisco, McKinney, Garland, Irving, and Grand Prairie — that they no longer control whether apartments can be built in commercially zoned areas. That decision, previously made through the local rezoning process with its public hearings, Planning and Zoning Commission reviews, and City Council votes, is now made by state law.

The response from those cities has ranged from legal analysis to legislative lobbying to creative zoning workarounds. The fight is not over. The 90th Texas Legislature convenes January 12, 2027, and the outcome of that session will determine whether SB 840 survives intact, is amended, or faces a sustained coalition of municipal opposition that could reshape its reach.

This article explains what SB 840 does, what the cities are doing about it, and what it means for land investors, developers, and property owners operating in the DFW corridor.

What SB 840 Actually Does

At its core, SB 840 is a by-right development law. It allows multifamily housing to be developed by right — without rezoning, without variances, and without public hearings — in areas that are currently zoned for commercial, office, retail, warehouse, or mixed-use development in the 19 affected cities. The law removes these cities' authority to require that a developer go through the standard rezoning process before building apartments in zones that allow commercial uses.

The practical scope of the law is substantial. The 19 cities it covers are defined by population thresholds: municipalities with populations over 150,000 located in counties with populations over 300,000. In the DFW context, this covers the region's largest and most economically significant suburban cities — not just the urban cores of Dallas and Fort Worth, but the growth suburbs that have defined North Texas's expansion over the past two decades.

The specific restrictions SB 840 places on those cities are precise:

• Cities may not require density below 36 units per acre for qualifying projects
• Cities may not require more than one parking space per residential unit
• Cities may not impose floor-area-ratio (FAR) limits on qualifying projects
• Cities may not impose height restrictions below 45 feet, or below the height of surrounding commercial uses, whichever is higher
• Cities may not use overlay districts or other zoning mechanisms to circumvent the by-right entitlement the law establishes

The result, in practice, is that a developer who owns or controls a commercially zoned parcel in one of the 19 affected cities can now pursue multifamily development without seeking a rezoning — eliminating what is frequently the most time-consuming, expensive, and uncertain step in the Texas entitlement process. According to the American Enterprise Institute's July 2026 analysis, SB 840 facilitated or unlocked more than 8,400 new residential units across the affected cities in its first nine months of enforcement.

What the Cities Are Doing About It

The municipal response to SB 840 has not been passive acceptance. Across the affected cities, the reactions have ranged from legal challenge to administrative maneuvering to direct legislative engagement — and in at least one case, a creative zoning workaround that drew a public rebuke from one of the law's key architects.

Frisco: The Workaround That Got Attention

The most visible and consequential municipal response to SB 840 has come from Frisco, Texas — one of the affected cities and one of the fastest-growing communities in the United States. Frisco's approach has been two-pronged: create a local zoning workaround to reduce the law's operational impact, and simultaneously lobby state lawmakers to amend or limit the statute before the next legislative session.

The zoning workaround Frisco employed is technical but meaningful. The city amended its Unified Development Code to create a heavy-industrial zoning category that mirrors SB 840's own statutory exemption — specifically, the provision that allows cities to restrict by-right multifamily development on parcels adjacent to certain heavy-industrial uses. By creating and applying a heavy-industrial zoning designation to commercial parcels it wanted to protect from apartment development, Frisco effectively shielded those sites from SB 840's by-right mandate while complying with the letter of the statute.

At the same time, Frisco officials met directly with four state lawmakers — Senator Brent Hagenbuch and Representatives Jared Patterson, Richard Hayes, and Keresa Richardson — requesting statutory changes or a full exemption from the law for cities that could demonstrate a specific planning rationale for exemption.

The response from Austin was pointed. State Senator Paul Bettencourt, one of the leading architects of Texas's 2025 housing reform legislation, publicly criticized Frisco's workaround as exactly the kind of local resistance the legislation was designed to address. The exchange put Frisco's approach on the record as a contested maneuver — and signaled that the same tactic, if replicated by other cities, would face scrutiny at the state level.

Dallas: Legal Options and Formal Opposition

Dallas's response has operated on a different track. Following SB 840's passage, members of the Dallas City Council explored legal options for challenging the law — examining whether any constitutional or statutory basis existed for a judicial challenge to the state's preemption of local zoning authority in this context. City officials had already registered formal opposition to SB 840 during the legislative session, placing Dallas on the record as opposed to the law before it passed.

The legal challenge avenue has not, as of September 2026, produced a filed lawsuit. But the city's willingness to explore it signals the depth of municipal opposition in one of Texas's largest cities — and the political dynamics that will shape the 2027 legislative debate.

The State's Case: A 320,000-Home Shortage

Understanding the SB 840 fight requires understanding what drove the Texas Legislature to pass it in the first place. The Senate Research Center's analysis entering the 89th legislative session identified a structural Texas housing shortage of approximately 320,000 homes — a deficit built over years of constrained housing supply in major Texas metros, driven in part by local zoning restrictions that limited density, slowed permitting, and increased the cost and uncertainty of residential development.

The Legislature's housing reform package — of which SB 840 is one element — was premised on the argument that local zoning authority, as exercised by Texas's largest cities, had become a structural impediment to housing production. By establishing by-right multifamily development in commercial zones, the state was effectively removing one layer of that impediment — replacing a discretionary process that could be delayed, contested, or denied with a statutory entitlement that cannot.

The counterargument, made by cities including Frisco and Dallas, is that local zoning authority is not merely an administrative mechanism — it is a planning tool that enables cities to coordinate housing development with the transportation, utilities, parks, and services that housing requires. Apartments placed by right in commercial corridors without local input, cities argue, may be built without adequate transit, without park access, and without the service infrastructure that residents will need. The result, in this framing, is not better housing but housing without adequate community investment to support it.

Both arguments contain merit. Both will be rehearsed, documented, and litigated — politically if not legally — before the 90th Legislature convenes in January 2027.

What SB 840 Does Not Do: The Private Covenant Boundary

One of the most practically important distinctions in SB 840 analysis is the boundary between what the law preempts and what it does not.

SB 840 preempts municipal zoning authority. It does not preempt private contractual obligations. Deed restrictions, CC&Rs, homeowners association covenants, Planned Unit Development agreements, and other private land use controls remain fully enforceable notwithstanding SB 840. A developer who controls a commercially zoned parcel that carries a deed restriction prohibiting residential use cannot invoke SB 840 to build apartments — the deed restriction is a private obligation, not a municipal regulation, and the state law does not reach it.

This distinction is critical for land investors evaluating the practical value of SB 840's by-right entitlement on specific parcels. A parcel that appears to benefit from the law based on its zoning designation may carry private covenants that eliminate the benefit in practice. Thorough due diligence on deed restrictions and private land use obligations is therefore not merely advisable for developers operating under SB 840 — it is essential.

The 2027 Session and What May Change

The 90th Texas Legislature convenes on January 12, 2027. The interim period between now and that session is already producing the coalition-building, interim committee hearings, and legislative preparation that will shape what the next session produces on housing and local zoning.

Several outcomes are plausible. SB 840 could be amended to provide exemptions for cities that meet specific planning criteria — a compromise that addresses some of the municipal concern without fully restoring local rezoning authority. It could be expanded to cover a broader set of cities or a broader range of zones. It could be challenged by a judicial ruling that addresses the constitutional scope of state preemption of local zoning authority. Or it could survive the session largely intact, with the municipal workarounds and lobbying campaigns having failed to produce a statutory change.

For land investors and developers underwriting projects in DFW today, the 2027 session is a material risk variable. The by-right entitlement that SB 840 provides on a specific commercially zoned parcel today may look different after January 2027. Building that legislative contingency into the investment thesis — not as a reason to avoid the opportunity, but as a variable to price and manage — is the disciplined approach.

What It Means for DFW Land Investors

For land investors evaluating DFW parcels in light of SB 840, the law's most direct implication is a reduction in entitlement risk on commercially zoned sites in the 19 affected cities. A parcel that previously required a rezoning to support multifamily development — with all the time, cost, and uncertainty that a rezoning involves — may now support that development by right. That change is real and meaningful: it compresses the entitlement timeline, reduces the capital at risk during the entitlement process, and eliminates the exposure to City Council denial that is the most binary risk in a contested rezoning.

The secondary implication is the one that requires more careful analysis. The adaptive reuse opportunity that SB 840 creates — converting aging commercial corridors, underperforming retail, and vacant office into multifamily housing — is genuine, but it is not uniformly available. Private covenants may block it on specific parcels. The 2027 session may modify it at the statutory level. And the municipalities that are most actively opposed to the law are also, in many cases, the municipalities with the strongest commercial real estate markets — meaning that the political opposition to SB 840 in Frisco and Dallas may produce faster and more aggressive local countermeasures than the law's proponents anticipated.

At Collective Acre, we track the intersection of legislative change and land investment opportunity in DFW because the two are inextricably linked. SB 840 has changed the entitlement calculus in nineteen Texas cities. Understanding which parcels benefit, which are blocked by private covenants, and what the 2027 session is likely to produce is the analysis that separates informed positioning from reactive speculation.

Conclusion

SB 840 is not a settled matter. It is the opening move in a legislative and regulatory negotiation between the state of Texas and its largest cities over who controls where apartments get built — a question that touches on housing affordability, urban planning, local democracy, and the fundamental architecture of Texas land use law.

In its first nine months, the law unlocked more than 8,400 residential units. It also produced a creative zoning workaround in Frisco, a legal review in Dallas, and a public rebuke from one of the state's most senior housing reform advocates. The 90th Legislature convenes in January 2027 with all of that on the record.

For DFW land investors, the opportunity is real. So is the need to understand exactly what the law does, what it does not do, and what it may look like in eighteen months. The most expensive assumption in Texas land development is the one that treats a current regulatory environment as permanent.
