MGL c. 40A § 3A — what it requires of 177 communities, what it costs, and what has been built
Section 3A of the Zoning Act requires every MBTA community to have at least one district of reasonable size where multi-family housing is permitted as of right — minimum gross density 15 units per acre, within half a mile of a station where one applies. Boston, though served by the MBTA, is exempt from the Zoning Act and therefore from § 3A.
Obligation scales with transit access: rapid transit 25% of 2020 housing stock, commuter rail 15%, adjacent community 10%, adjacent small town 5% — capped at 25% where the two calculation methods would exceed it.
As determined by EOHLC. Adopting zoning locally is not the same as being found compliant; a community must also apply to EOHLC for a determination.
In units of zoned capacity. These are the raw obligations, which track population — the proportional burden is a different ranking and is below.
Each category carries a nominal share of 2020 housing stock — rapid transit 25%, commuter rail 15%, adjacent community 10%, adjacent small town 5%. For 44 of the 177 communities the requirement lands above that share. This is the gap, in percentage points.

The most-quoted number attached to § 3A is a cost estimate that did not come from the state. It comes from research prepared by Anne Brensley for the State Auditor, and it estimates one narrow slice of compliance cost — architects' and engineers' base fees — by applying the state's own DCAMM fee schedule to the mandate's required capacity. It is presented here as her attributed estimate, with its inputs shown, because the figure only means anything if you can see how it was built.
Designer fees are the narrow part. None of the following is in the $4.49B, and none of it has been quantified by the state either.

EOHLC maintains a tracker of multi-family developments it has determined are associated with 3A zoning. It is the closest thing to an answer to the question the law's supporters and opponents actually disagree about: does rezoning produce housing? Here is what the state's own tracker currently shows.

This section is carried over from the original “Follow the Money” investigation and is a fixed piece of research, not a live feed. It rests on public records: OCPF campaign finance filings, Secretary of the Commonwealth lobbyist registrations, IRS Form 990 filings via ProPublica, corporate registrations, and published reporting. Aggregations were performed on roughly 107,900 OCPF contribution records for the four officials who authored, implemented or enforce § 3A — Sen. Brendan Crighton, Gov. Maura Healey, AG Andrea Campbell and Rep. Kevin Honan. Full method is in the project's methodology document, linked at the foot of this page.

The questions the available record raises and does not answer. These are framed as questions because that is what they are — each one is answerable with data that exists but has not been published, or with disclosure that is not currently required.
| Question | What the record shows |
|---|---|
| What does the law require? | Zoning changes — not construction. |
| Does rezoning create housing? | No. Capital, labor, and market demand create housing. |
| Will the rezoned units be affordable? | No affordability mandate exists in § 3A. |
| What does new multifamily cost to build? | $350+ psf. A 900sf unit = $315K+ construction cost alone. |
| Is the market building? | Permits down 44%. Interest rates 6%+. Market is frozen. |
| Who pays for compliance? | Towns. $4.49B in designer fees. State appropriated $15M (0.3%). |
| What happens if towns don't comply? | They lose state infrastructure funding they already need. |
| So what does the law actually accomplish? | It transfers zoning control from towns to the state — and shifts liability for future development costs to municipalities. |
