Where today's law sits

The old version: off the chart — A racial covenant, a flat ban on apartments, a one-acre minimum lot, and a board with an absolute veto.

  1. Measuring by map (L2) A density floor of 15 units per acre within half a mile of transit — the exclusionary number turned upside down; bounded only by the guidelines.
  2. Who's left out entirely (L4) Age restrictions barred; the housing must suit families with children.
  3. Who decides? (L1) As of right inside the district, but the town still chooses where the district goes.
  4. Where the line is drawn (L3) The only stated penalty is loss of four discretionary grants — an exit ramp for towns that don't need them.
  5. Automatic penalty, judgment call — or nothing? (L6) No enforcer named and no statement that compliance is mandatory; a court had to supply both.
  6. Who does the paperwork? (L8) The town must create the district — but the only thing pushing it to act is the soft funding penalty.
  7. An affordability requirement (none) Missing from the text — Nothing in the text requires any of the new housing to be affordable.
One row for each drafting decision in this law. The dot shows where today's choice sits: toward the left is the rigged version — the worst law that would still look fair on paper — and toward the right is the most protective version. A solid dot is a choice the text makes; an open circle is a decision the text does not make at all. The old, openly discriminatory version sits off the chart; it is noted once for history and never used as the comparison.

Today's law is strong on what it requires — near the most protective end on substance — but sits near the rigged end on whether it bites: the text names no enforcer and states only a penalty the wealthiest towns can shrug off.

Every one of these decisions was made by a person — some deliberately, some by copying an old form, some by not thinking it through. This audit does not sort out which. It shows what each decision does, because the ramifications are the same whether the choice was intentional, inherited, or sloppy. What changes after the audit is this: once you can see where a decision sits and what it costs, keeping it becomes a decision too.

What we found

Where today’s law sits. Split, and unusually so. This is an anti-exclusionary statute, and a fair audit should say so. On the two drafting decisions that historically drove suburban exclusion — measuring by map (L2) and who’s left out entirely (L4) — today’s law sits at or near the most protective end. It turns the classic exclusionary move upside down: instead of letting a town cap density, it requires a floor, “a minimum gross density of 15 units per acre,” within half a mile of transit. And it closes the over-55 dodge that lets a town admit “multifamily” while excluding families: the housing must be “without age restrictions and shall be suitable for families with children.” That is a real structural fix, not a cosmetic one.

But on what happens when a town refuses — automatic penalty, judgment call, or nothing? (L6) — today’s law sits much closer to the rigged version. The only consequence the text states is that a community that “fails to comply with this section shall not be eligible for funds from” four discretionary grant programs (subsection (b)). For the wealthiest exclusionary communities — exactly the ones the law targets — those grants are optional, so the stated penalty is close to no penalty. The text names no enforcer and never says compliance is mandatory.

The trouble spot. A strong requirement with a weak, ambiguous way of making it stick — not a hypothesis; the litigation proved it. In Attorney General v. Town of Milton, SJC-13580 (Jan. 8, 2025), the Commonwealth had to go to the Supreme Judicial Court to establish three things the statute left unsettled: that compliance is mandatory; that the Attorney General may enforce it by seeking a court order; and — a holding the popular summaries often omit — that the state housing office’s compliance guidelines were legally ineffective because they had never been issued as regulations under the Administrative Procedure Act (G.L. c. 30A), forcing the office to re-issue them as emergency regulations. A requirement whose enforcement and whose implementing standards both had to be rescued by a lawsuit is a textbook trouble spot.

Where the line is drawn (L3) makes it worse. The funding penalty is an exit ramp in reverse: a town that gives up the grants escapes the only stated consequence. The communities that need state money least are the least deterred.

Who decides (L1) and who does the paperwork (L8) are mixed. Inside the required district, housing is “permitted as of right” — no special permit, no discretionary denial. But the town still chooses where to draw the district, and the ordinary zoning-adoption vote under G.L. c. 40A, § 5 sits upstream. The burden of creating the district rightly rests on the municipality; the only thing pushing it to act is the soft funding penalty. (One point to verify measure by measure: the 2020 Housing Choice Act, St. 2020, c. 358, lowered the usual two-thirds zoning vote to a simple majority for housing-promoting changes, which on most readings covers these districts.)

What’s missing. Today’s law reaches one district per municipality, leaves its location and design to local choice, relies on a soft funding penalty, and contains no affordability requirement. The most protective version — modeled on Cambridge’s February 2025 citywide reform — reaches all residential land as of right, pairs the density floor with an affordability set-aside, and makes the remedy work on its own rather than depending on the threat of lost grants. The affordability gap is a deliberate design question, not an oversight to label as bias: market-rate density adds supply without guaranteeing affordable units, and choosing supply alone is a defensible policy choice.

Fact-check. The enforcement weakness rests on strong proof — the Milton litigation itself. So does the finding that exclusionary zoning concentrates low-income households and households of color and restricts access to opportunity; one circulating figure needs correcting: under the 2025 EOHLC Subsidized Housing Inventory update, 94 of 351 municipalities exceed Chapter 40B’s 10 per cent threshold, not the stale 67. Whether the density floor will measurably desegregate is, as of 2026, only weakly to moderately supported — outcome data on housing actually built under the law is thin. That is a research gap, not an all-clear.

Options for the drafter

Options to weigh, not instructions:

  1. Write the Milton holdings into the text. An express statement that compliance is mandatory and an express grant of Attorney General enforcement authority would turn a mandate rescued by a court into one that stands on its own — the highest-value target if the section is reopened. A builder’s remedy — a qualifying developer gets approval directly where the town’s zoning does not conform — is the structural cure for the “we’ll forgo the grants” escape; whether it is wanted or politically viable is a separate call.
  2. Choose a consequence the target can’t decline. A consequence that does not depend on a town’s appetite for discretionary grants — for example, making non-conforming density caps unenforceable against qualifying multi-family housing — closes the exit ramp.
  3. Decide the affordability question on purpose. Pairing market-rate density with an inclusionary set-aside and a density bonus is the most protective version’s move. Put the fork on the record, with the Chapter 40B interaction noted.
  4. Decide where the size limits live. The statute requires a district of “reasonable size” and directs the housing office to “promulgate guidelines” (subsection (c)); the guidelines, not the statute, carry the 50-acre minimum and the caps on how much housing the floor can produce (capacity at 25 per cent of existing stock, land at 1.5 per cent of developable area). That is where a strong floor gets quietly bounded. In the statute, limits are more durable and less flexible; in the guidelines, more flexible and — after Milton — good only if properly issued as regulations. Worth an explicit choice.
  5. Two questions belong to other reviews: a statewide builder’s remedy and an override of local density caps raise home-rule and possibly takings questions; no fiscal or feasibility analysis is attempted here. Flagged for counsel and the companion analyses.

Will it survive the paperwork? Today’s law is the cautionary case: the requirement survived Milton; the guidelines did not, because they were never issued as regulations — and a protection tied up in court protects no one while it waits.

How to spot this pattern in a live bill

A bill can be written to look like this reform while producing almost nothing, naming no group. The tells:

  1. A goal stated up front, but every working detail — “location, dimensions, density” — handed back to local discretion.
  2. The word “may” where the goal needs “shall.”
  3. A numeric floor removed, or replaced with an undefined adjective like “reasonable.”
  4. A protective coverage clause quietly reversed — age-restricted housing counted as compliance again.
  5. A penalty pegged to something the target can decline.
  6. Enforcement “committed to the discretion of” the party being regulated — or simply left silent.

Any two or three of these together in a housing, benefits, or permitting bill warrant a closer look.
