383 Washington Street, LLC files comprehensive permit application
A Chapter 40B comprehensive permit application is filed with the Braintree Zoning Board of Appeals covering two parcels on Washington Street. The application qualifies as an eligible subsidized-housing project under M.G.L. c. 40B §§ 20-23.
approx.ZBA Hearings
Braintree ZBA asserts General Land Area Minimum safe harbor
Braintree denies the comprehensive permit, invoking the General Land Area Minimum (GLAM) safe harbor under 760 CMR 56.03. Braintree calculates that 1.65% of its land zoned for residential, commercial, or industrial use contains low- or moderate-income housing — above the 1.5% statutory threshold for safe-harbor protection.
Housing Appeals Committee review
HAC calculates 1.39% and rejects Braintree's safe-harbor claim
The Massachusetts Housing Appeals Committee (HAC) recalculates the GLAM figure at 1.39% — below the 1.5% threshold. HAC treats a 244-acre conservation parcel within a residential zoning district as part of the GLAM denominator, rejecting Braintree's exclusion. The denial is overturned; the comprehensive permit is ordered.
Superior Court review
Superior Court affirms HAC's denominator methodology
On administrative appeal, the Massachusetts Superior Court affirms HAC. The court holds that the 'zone' in the GLAM regulation refers to the municipality's applicable zoning map, not to a distinct area or sub-region within a zoning district — meaning undevelopable conservation acres inside a residential district still count toward the GLAM denominator.
June 18, 2025
Massachusetts Appeals Court affirms in 2025 WL 1699014
The Massachusetts Appeals Court unanimously affirms the Superior Court's ruling, holding that Braintree's exclusion of 244 conservation acres from its GLAM denominator was error. Braintree's 1.65% figure is rejected; HAC's 1.39% controls. The Braintree ZBA's denial of the 383 Washington Street comprehensive permit is vacated; the project proceeds on HAC-ordered terms.
The Legal Mechanism
Chapter 40B Comprehensive Permit
M.G.L. c. 40B §§ 20-23 allows a single comprehensive permit from a local ZBA for affordable-housing projects that would otherwise require multiple local approvals. A ZBA denial can be appealed to the state Housing Appeals Committee, which reviews the denial de novo and can order the permit issued.
The Safe Harbor at Issue
General Land Area Minimum (GLAM)
Under 760 CMR 56.03, a municipality is presumed consistent with local needs — and its comprehensive permit denial is shielded from HAC reversal — when at least 1.5% of the total land area zoned for residential, commercial, or industrial use contains low- or moderate-income housing. Fall below 1.5% and safe harbor is lost.
The Disputed Acres
244 Conservation Acres Inside a Residential District
Braintree argued the 244-acre conservation parcel should be excluded from the GLAM denominator because it is legally undevelopable. The Appeals Court disagreed: 'zone' in the regulation means the applicable zoning map, and conservation land inside a residential zoning district is part of that district's residential-zoned area regardless of its undevelopable status.
The Precedent Value
Every MA Jurisdiction Must Recount
The 2025 Appeals Court ruling applies to every GLAM defense going forward. Jurisdictions with meaningful conservation acreage inside residential, commercial, or industrial zoning districts now must include that land in the safe-harbor denominator — reducing the numerator share and, in many cases, flipping jurisdictions from safe-harbor to ineligible.
Key Decision Makers & Stakeholders
The record that decided this denial.
Braintree Zoning Board of Appeals
Local Permit Authority
Braintree, Massachusetts
Documented Record
Denied the 383 Washington Street comprehensive permit and invoked the GLAM safe harbor. Calculated the municipality's low- or moderate-income housing share at 1.65% of residential-, commercial-, and industrial-zoned land — above the 1.5% statutory threshold. Excluded a 244-acre conservation parcel from the denominator.
The ZBA's posture is the standard 40B safe-harbor play: invoke the statistical threshold, shield the denial from HAC de novo review, and force the applicant to litigate the math. The defect here was narrow and technical — whether one 244-acre conservation parcel counts in the denominator — but it swung the ruling and vacated the denial. Every MA ZBA running the GLAM defense now must audit its denominator against the 383 Washington methodology.
Massachusetts Housing Appeals Committee
State De Novo Review Tribunal
Commonwealth of Massachusetts
Documented Record
Recalculated Braintree's GLAM share at 1.39%, below the 1.5% threshold. Included the 244-acre conservation parcel in the denominator. Overturned the ZBA denial and ordered the comprehensive permit issued on its terms.
HAC is the structural check on local 40B denials. The committee's authority to conduct de novo review of safe-harbor math — including GLAM calculations — is the reason Chapter 40B functions as a state-level preemption tool rather than a veto-shaped local ordinance. The Braintree ruling affirms HAC's methodology is the one that controls.
383 Washington Street, LLC
Applicant / Appellee
Braintree, Massachusetts
Documented Record
Filed comprehensive permit application under M.G.L. c. 40B §§ 20-23 on two Braintree parcels. Appealed ZBA denial to HAC; prevailed on GLAM denominator methodology; survived Superior Court and Massachusetts Appeals Court review.
The applicant ran the complete 40B appeal chain — ZBA, HAC, Superior Court, Appeals Court — over multiple years to overturn a denial grounded in a 26-basis-point safe-harbor claim. The case illustrates that 40B's comprehensive permit process is best modeled as a three-year litigation exercise, not a one-cycle permit process.
Massachusetts Appeals Court Panel
2025 WL 1699014
Boston, Massachusetts
Documented Record
June 18, 2025 decision affirmed Superior Court and HAC. Held that 'zone' in 760 CMR 56.03 refers to the applicable zoning map, not to distinct sub-areas of a zoning district. Conservation acres inside a residential zoning district count toward the GLAM denominator.
The ruling is the controlling statewide authority for GLAM calculations going forward. Until the Supreme Judicial Court revisits the question, municipalities cannot exclude conservation land inside residential, commercial, or industrial zoning districts from their safe-harbor math. Any 40B denial that relied on a pre-2025 denominator is now vulnerable.
Massachusetts Superior Court
Intermediate Appellate Review
Commonwealth of Massachusetts
Documented Record
Affirmed HAC's denominator methodology and Braintree's loss of safe harbor. Held the regulatory term 'zone' means the applicable government zoning map rather than a distinct sub-area.
The Superior Court's affirmance provided the intermediate record the Appeals Court reviewed. The two-court chain — HAC, Superior Court, Appeals Court — is the standard path for 40B safe-harbor appeals; budget for it in any comprehensive permit pro forma.
EOHLC / Prior DHCD Regulation Drafters
Mass. Executive Office of Housing & Livable Communities
Commonwealth of Massachusetts
Documented Record
Promulgated 760 CMR 56.03 containing the GLAM safe-harbor rule. The regulation's undefined use of 'zone' was the interpretive question the Appeals Court resolved.
The agency's regulatory drafting choice — leaving 'zone' undefined — left the denominator methodology open to litigation. Expect a post-383 Washington update to clarify the rule rather than relitigate it in every jurisdiction. Track EOHLC rulemaking as part of any Massachusetts 40B diligence.
