The town that lost at the Supreme Judicial Court on Friday had already done the thing it was suing to avoid. Marshfield town meeting adopted compliant multifamily zoning on October 20, 2025, by a vote of 363 to 209, on the third attempt after rejecting it twice. The SJC handed down its decision eleven months later, on September 18, 2026, and the opinion runs 22 pages without mentioning that vote once.
It did not have to. The court was reviewing a complaint filed in February 2025, and on a motion to dismiss the world outside the four corners of that complaint does not exist. So the practical effect on Marshfield is close to zero. The town already drew its district. The real audience for this opinion is the eight communities that are still refusing, and anyone who has been underwriting land or multifamily in one of them on the theory that the law might go away.
That theory is done. Not because a court declared the statute bulletproof, but because the SJC just published, in detail, what a town would have to prove to get out from under it, and nothing a rezoning actually costs comes close to clearing that bar.
Here is the part I think most people are going to miss. The lawsuit was never what set land values in these towns. The map is. The court decided whether a town has to draw a multifamily district. It said nothing at all about where that district goes, and where it goes is the entire investment question. That gets settled in a school gymnasium at a town meeting, and in the eight holdout towns most of those meetings have not happened yet.
What the court actually decided on September 18
The case is Town of Marshfield & another vs. Commonwealth & another, SJC-13840. Argued March 4, 2026, decided September 18, 2026, written by Justice Serge Georges Jr., with Chief Justice Budd and Justices Gaziano, Kafker, Wendlandt, Dewar and Wolohojian all on the panel. No dissent, no concurrence.
Marshfield brought four arguments and lost all four.
On the unfunded mandate claim under G. L. c. 29, section 27C, the court held the complaint did not plausibly allege one. Marshfield said it spent money evaluating and drafting zoning bylaws and presenting them at town meeting. The court’s answer was that the complaint “does not describe the nature, amount, or necessity of those costs in a way that plausibly suggests they were unavoidable expenditures required by the MBTA Act, rather than incidental local administration expenses or costs Marshfield chose to incur in pursuing its preferred path to compliance.” Marshfield’s claim about future costs fared worse. Describing future costs as direct, the court said, “states a legal conclusion, not a well-pleaded fact.”
On the voting rights claim, the court did not even reach the merits. Marshfield and its select board have no standing to assert the constitutional voting rights of Marshfield town meeting voters, because a town is a political subdivision of the Commonwealth and cannot raise constitutional challenges against the state that created it. Board members suing in their official capacities, with no personal injury alleged, were out for the same reason.
On home rule, the court reached a claim it found was waived, because the issue was important enough to settle. The Home Rule Amendment “does not prevent the Legislature, through a valid general law addressing a matter of Statewide concern, from imposing substantive requirements that municipalities must implement through existing local procedures.” Housing is a statewide concern. The act is a valid general law.
And on the Zoning Act argument, that requiring compliant zoning effectively forces town meeting to vote yes, the court gave the line that the eight remaining holdouts should read twice: “Town meeting voters retain the authority to debate, amend, approve, or reject any proposal placed before them under section 5. But that authority does not include the power to exempt the town from an obligation imposed by a valid State law.”
Rejecting the article is still allowed. It just produces noncompliance, not an exemption.
The one door the SJC deliberately left open
I want to be precise here, because the coverage has been sloppier than the opinion.
The SJC did not hold that MBTA Communities Act compliance can never be an unfunded mandate. It said the opposite in so many words: “We therefore need not decide whether costs associated with MBTA Act compliance are categorically excluded from section 27C.” What died on Friday was Marshfield’s complaint, not the legal theory in the abstract.
That distinction matters for about five minutes, and then it stops mattering. Read what the court required. A town would have to plead specific, itemized, municipality-specific costs that were mandatory rather than voluntary, and that exceeded incidental local administration expense. Then look at what a rezoning actually generates: consultant fees, a planning board process, warrant articles, a public hearing, a town meeting. The court just labeled that entire category either incidental or self-inflicted.
The strongest fact Marshfield had was not its own. In February 2025 the Division of Local Mandates, inside the State Auditor’s office, sent letters to Methuen, Middleborough and Wrentham concluding that the MBTA Act is an unfunded local mandate. A state agency agreed with the towns. The SJC dispatched it in a paragraph: those letters were not about Marshfield, did not identify municipality-specific mandatory costs, and “do not supply the facts missing from the complaint.”
If a favorable determination letter from the State Auditor’s own division does not move the needle, I do not know what a ninth town is supposed to file.
Who is actually left, and what each of them owes
Attorney General Andrea Campbell sued nine communities on January 29, 2026: Dracut, East Bridgewater, Halifax, Holden, Marblehead, Middleton, Tewksbury, Wilmington and Winthrop. All nine had missed the July 14, 2025 deadline set by the post-Milton regulations. At that point 165 of the 177 covered communities had complied.
Marblehead has since adopted zoning and reached interim compliance in May 2026, with its application still in review at the Executive Office of Housing and Livable Communities. That leaves eight towns genuinely holding the line, out of 177.
These towns are not all the same problem, and lumping them together is where most of the commentary goes wrong. Four are commuter rail or served communities with a real transit obligation. Others are adjacent communities and adjacent small towns with no station at all, which means no half mile transit siting requirement and a great deal of freedom about where the district lands.
Wilmington is the one I would stare at. It has two commuter rail stations, Wilmington station on the Lowell Line at Main Street in the town center and North Wilmington on the Haverhill Line off Middlesex Avenue. Its obligation is 1,248 units with half the district inside a half mile of a station. The district that voters killed on May 3, 2025 ran along Main Street through the train station, and the town’s own estimate was that it would produce fewer than 200 actual new units. They rejected it anyway.
What holding out has already cost, in cash
Noncompliance is not a free option. Section 3A(b) cuts a town off from the Housing Choice Initiative, the Local Capital Projects Fund, MassWorks and HousingWorks by statute, and the Healey administration has extended the freeze to discretionary grants well beyond that list. The bills are not theoretical.
Tewksbury’s losses are the ones that would get my attention if I lived there. Three Department of Elementary and Secondary Education grants went ineligible: a $50,000 Early College planning grant, $250,000 in Early College designation funding spread over five years, and a $50,000 implementation grant. That is school money, traded for a zoning district that the town’s own planning consultants say it can site in an office park.
The Lowell Line test: Woburn complied, Wilmington did not
This is where I can bring something to the argument that the news coverage cannot, because we pull directly from MLS PIN rather than from a national portal’s town page.
The standard holdout argument is that by-right multifamily zoning will damage the single family market. Woburn and Wilmington sit on the same Lowell Line, eight minutes apart. Woburn rezoned. Wilmington refused. Here is what actually closed in both towns over the identical six month window from March 1 through August 31, 2026.
Woburn has had compliant by-right multifamily zoning on the books since 2023. Its single family average is $860,843 on 57 days. Wilmington held the line and sits at $872,591 on 61 days. The compliant town and the defiant town are within a percent and a half of each other on price and four days on market, and the defiant one is marginally slower.
If rezoning were the value destroyer these town meetings keep describing, that gap would not look like noise. It would look like something. It looks like nothing.
The column that should actually worry a Wilmington homeowner is the last one. Zero. In six months, across 120 closed sales of every kind, Wilmington did not record a single multifamily transaction. It also did not record a single vacant land sale, and I widened that one to a full twelve months before I believed it. A town with two commuter rail stations produced no land trades and no income property trades in a year.
Winthrop is already the thing it is fighting
Here is the number that ended the debate for me.
Winthrop is suing to avoid zoning for 882 units of multifamily housing. Over that same March through August window, 22 of Winthrop’s 99 closed sales were multifamily income properties, and only 23 were single family. Multifamily was 22.2 percent of everything that traded. Winthrop’s three families averaged $1,202,250 and its four families closed between $1,240,000 and $1,331,000.
Winthrop Town Council President Jim Letterie told CommonWealth Beacon, “I’m a no at 800 units. I’m a no at one unit. Not because of the number of units, but because we are being told what to do with our town.” I understand the sentiment. It is also an argument about autonomy, not about housing form, and it is worth separating the two, because a Winthrop resident reading a doomsday flyer about multifamily housing is reading about the town they already live in. The two and three family is the native building type on that peninsula. It sells at over a million dollars.
The mandate is settled. The map is wide open.
Now the part that matters for money.
Every one of these towns is going to end up with a compliant district. What none of this litigation determined is where. And the state’s own record shows how much latitude that leaves.
Boston Indicators published an analysis by Amy Dain in January 2026 finding that roughly 7,000 units are in the permitting, construction or occupancy pipeline across more than 100 projects in 34 communities as a direct result of Section 3A rezonings. That is real. But only about 30 percent of those pipeline units sit within a half mile of a train station, and 19 projects of 100 units or more account for roughly three quarters of the total. Dain’s own framing is that the law’s “hallmark flexibility leaves a lot of leeway for communities to embrace or sidestep the law’s housing goals.”
Sidestep is the operative word. Marshfield complied by putting its district where redevelopment is unlikely. Tewksbury, as an adjacent community with no station and therefore no transit siting requirement, is bringing two subdistricts to its October 6 special town meeting: one on Clark Road and one at the Lodge at Ames Pond, in an office research district. Both were recommended unanimously by the select board and planning board in June and confirmed as compliant by the Northern Middlesex Council of Governments. Both are legitimate. Neither is downtown.
So the thesis “buy land in a holdout town because the upzoning is coming” is half right, and the missing half is the expensive half. The upzoning is coming. It is not coming to every parcel, and in a town with no station it may not come anywhere near the parcel you assumed.
Tewksbury’s land market makes the point. Two commercial land parcels have closed there in the last year. 937 North Street, 3.16 acres, sold for $2,200,000 in September 2025 at 100 percent of its original ask after 503 days on market, which works out to $696,203 an acre. 1325 Main Street, 2.09 acres, closed on September 10, 2026 for $1,500,000 after 867 days on market and a cut from $1,750,000, which works out to $717,703 an acre. Two trades a year apart at effectively the same per acre price, both after more than a year and a half of marketing. Neither is inside the district the town votes on October 6.
That is what a land market with no zoning visibility looks like. Long holds, wide bid ask spreads, and pricing that has nothing to do with density because nobody knows what the density will be.
The honest counterargument, which is political and not legal
I do not think the remaining holdouts have a legal path. I do think they have a political one, and it would be dishonest to write this without saying so.
Massachusetts votes for governor in November 2026. Governor Healey’s Republican opponent, Mike Minogue, has said he would end state enforcement of the MBTA Communities Act and provide legal support to cities and towns that oppose it. That is not a fringe position in the nine towns that got sued.
Weigh it honestly. A new administration cannot repeal a statute, and Section 3A’s grant ineligibility is written into the law itself rather than into an enforcement posture. The Attorney General is separately elected and her authority to bring these suits was settled in Milton in January 2025. What a governor could do is slow-walk EOHLC, soften the regulations, and change the political weather. That is a meaningful risk to the timeline. It is not a path back to single family only zoning.
If I were underwriting a five year hold, I would treat the election as schedule risk, not as an exit.
How I would underwrite these eight towns right now
For investors and land buyers:
1. Stop paying for optionality you do not have. If your model has a branch where the town gets an exemption, delete it. After Milton and now Marshfield, that branch is gone.
2. Underwrite the map, not the mandate. Before you bid on a parcel in Wilmington, Tewksbury, Holden or Middleton, find the town’s actual proposed district boundaries in the planning board packet. In Tewksbury that is Clark Road and the Lodge at Ames Pond. Anything else is speculation about a second district that may never be drawn.
3. Separate station towns from adjacent towns. Wilmington has to put half its district inside a half mile of a station, which is a hard geographic constraint you can underwrite. Tewksbury, Holden, Middleton and Halifax have no such constraint, which means transit adjacency is an amenity story in those towns and not a zoning one.
4. Price the delay. 867 days on market for a 2.09 acre Main Street parcel is your carry assumption, not 180 days. These are not liquid markets and a favorable court ruling did not make them liquid.
For move-up buyers looking at Holden, Tewksbury or Wilmington specifically because those towns have resisted density:
5. You are buying a house, not a zoning outcome. If low density is the only reason a town is on your list, take it off. The resistance was never going to hold, and now it has been told so twice by a unanimous court.
6. Look at what the compliance actually produced next door. Woburn rezoned in 2023 and its single family market is indistinguishable from Wilmington’s today. That is the best available evidence of what happens to your equity, and it is better evidence than anything said at a town meeting.
For owners in the holdout towns:
7. Price in the grant freeze, because it is a real municipal budget item. Middleton gave up a $2,000,000 MassWorks award. Tewksbury gave up $350,000 in school grants. Those are costs that land on a tax rate or on a service cut, and they are the one genuine financial consequence of the fight that the litigation never addressed.
8. If you own a two or three family in one of these towns, you own the scarcest product on the board. Wilmington recorded zero multifamily trades in six months. That is not a soft market. That is an absent one, and it is about to get a legal supply of competitors.
Where this leaves things
Five years in, the score on the MBTA Communities Act is 177 communities covered, 8 still refusing, and zero successful legal challenges. Milton lost on enforcement. Marshfield lost on funding, standing, home rule and the Zoning Act, and by the time it lost it had already rezoned. The amicus briefs on the state’s side in the Marshfield case came from the Greater Boston Real Estate Board, the Massachusetts Association of Realtors, NAIOP Massachusetts, the Home Builders and Remodelers Association, MAPC, CHAPA and MassHousing. When the realtors, the developers, the planners and the affordable housing advocates all file on the same side, the outcome was not close.
What is genuinely unresolved is the part nobody litigated. Eight zoning maps have not been drawn yet, one of them gets voted on in Tewksbury on October 6, and the difference between a district at a train station and a district in an office park is the difference between a land basis that works and one that does not.
If you are weighing a parcel or a multifamily in one of these towns, or trying to decide whether a town’s resistance should factor into where you buy, I am happy to walk through the actual district boundaries and the closed comps with you. Reach out anytime.
