Massachusetts has taken an unusual and high-stakes step in its ongoing effort to address the state’s housing shortage: the Attorney General has filed a lawsuit against nine towns for failing to comply with a major housing law, underscoring the Commonwealth’s growing willingness to use legal enforcement — not just encouragement — to open up land for multifamily housing.
On January 29, 2026, Massachusetts Attorney General Andrea Joy Campbell filed suit in Suffolk Superior Court against nine municipalities that missed critical zoning requirements under the MBTA Communities Act, a 2021 state law designed to expand housing supply near public transit. Per (Axios), the AG is seeking a court order compelling these towns to adopt zoning that allows multifamily housing “as of right,” rather than making it difficult or discretionary — a move officials believe is essential to boosting statewide housing production.
This legal action could have significant implications not only for the communities named in the lawsuit but for housing policy, real estate investment, and market dynamics across Massachusetts in 2026 and beyond.
What the Law Requires
The MBTA Communities Act — enacted as part of a broader push to confront the state’s persistent housing shortage — applies to cities and towns served by the Massachusetts Bay Transportation Authority (MBTA), as well as certain adjacent municipalities. Under the law, these communities must adopt zoning that allows multifamily housing by right in at least one district of reasonable size near transit. In plain terms, that means developers shouldn’t need special permits or variances before building duplexes, triplexes, or small apartment buildings in those zones.
The intent is straightforward: ensure that areas already served by transit — where infrastructure exists — are able to support more homes, reduce sprawl, and expand housing access and affordability.
However, compliance has been uneven. While most of the 177 affected communities adopted compliant zoning by the extended deadlines, twelve towns missed the final end-of-2025 deadline, prompting the AG’s decision to pursue enforcement.
Who Is Being Sued — And Why It Matters
The lawsuit names these nine municipalities:
- Dracut
- East Bridgewater
- Halifax
- Holden
- Marblehead
- Middleton
- Tewksbury
- Wilmington
- Winthrop
Attorney General Campbell’s office is asking the court to require each town to adopt zoning that meets the law’s requirements. In announcing the lawsuit, Campbell emphasized the urgency of the housing shortage, stating that compliance with state law is mandatory and that enforcement is necessary when municipalities lag far behind their obligations.
Some of the towns targeted have already indicated plans to revisit zoning choices. For example, Holden scheduled a zoning vote for February 23, 2026, suggesting parts of the legal action may ultimately align with local efforts already underway.
Why the State Is Taking This Step Now
For years, Massachusetts has relied on a mix of incentives, planning efforts, and voluntary compliance to address housing production challenges, especially near transit. But with housing costs continuing to outpace incomes, and development pipelines still constrained, officials are increasingly pushing for enforceable action as part of a broader affordability strategy.
Importantly, the Attorney General’s strategy to sue noncompliant towns doesn’t come out of nowhere. Previous legal challenges — including one involving the town of Milton — have already established that the law can be enforced in court, even amid disputes over implementation and procedure. In 2025, the Massachusetts Supreme Judicial Court upheld the law’s constitutionality and confirmed that the Attorney General has the power to enforce it, clearing the path for actions like this one.
In addition, enforcement isn’t the only tool the state has used. Towns that missed earlier deadlines have also lost eligibility for certain state grant programs, which provide a financial incentive to comply with the law.
Why Zoning Compliance Matters for Housing Supply
At its core, this lawsuit is about where and how housing gets built.
Zoning — the local rules that determine what can be built on a piece of land — has long been a major factor in housing affordability. Exclusionary zoning that limits development to single-family homes, or that requires lengthy permitting processes, tends to suppress housing supply and drive up prices. When zoning allows multifamily housing “by right,” developers can move more quickly and predictably, and pricing tends to be more competitive.
By requiring multifamily zoning near transit, the MBTA Communities Act aims to unlock land that has the infrastructure to support more housing units, helping create options for families, renters, and first-time buyers who might otherwise be priced out.
When towns resist or delay compliance, those opportunities shrink — and supply constraints tighten further. The lawsuit signals that the state sees zoning compliance not just as policy guidance but as a legal obligation tied to long-term affordability goals.
How This Could Impact the Real Estate Market
For real estate professionals — from brokers to developers to investors — this enforcement action could shape market conditions in several ways:
1. Increased Focus on Transit-Oriented Communities
Communities that comply with the law may attract more builders and interest from buyers seeking housing near transit — a trend that can have ripple effects on property values and development patterns.
2. Greater Zoning Certainty
If the courts rule in favor of the Attorney General, it could give developers and lenders more confidence in planning projects, especially small-scale multifamily or mixed-use developments that rely on clear zoning requirements.
3. Policy as Market Signal
Legal enforcement sends a message that Massachusetts intends to pursue housing supply growth more aggressively than in past years. This could influence where capital flows and which markets gain developer attention in 2026 and beyond.
4. Ongoing Debate Over Local Control
Expect pushback in some communities that view the law as intrusive or as infringing on local planning autonomy. That tension can itself influence market sentiment and local political dynamics.
What’s Next
The lawsuit is a developing story. Key milestones to watch in the coming months include:
- Court hearings and rulings: Whether the judge sides with the Attorney General and how quickly orders to rezone may be issued.
- Local zoning votes: Some towns named in the suit have already scheduled or may schedule zoning changes — potentially resolving the dispute before or during litigation.
- State engagement: Whether the Executive Office of Housing and Livable Communities provides additional guidance or assistance to bring other noncompliant towns into compliance.
Massachusetts’ approach reflects a broader national conversation about how states and municipalities can work together — or clash — over housing policy in markets where affordability is a growing concern.
