Boston board approves scaled-down Dorchester apartment addition

Boston board approves scaled-down Dorchester apartment addition

Built World Boston, MA local

Ten-unit rear addition to Second Empire-style house on Mount Everett Street cleared the Zoning Board of Appeal after revisions cut density and added parking.

Today: Zoning board approves revised ten-unit addition

Overview

Updated 1 hour ago

A Dorchester property owner won unanimous zoning approval for a three-story, ten-unit rear addition to an existing Second Empire-style house at 24 Mount Everett Street. The $3.6 million proposal by developer Diarmaid McGregor includes 16 parking spaces—four of them mechanical stackers—and 16 bicycle storage spots.

The vote caps a two-year revision process. Neighbors first saw a four-story, 16-unit addition with no parking; after a heated community meeting, McGregor cut a floor, trimmed housing units, and added vehicle parking. Two of the ten units rent at or below 70% of the Boston area median income, meeting the city's inclusionary zoning policy.

Why it matters

Each zoning board approval like this one determines whether Boston gains housing supply in established neighborhoods—and the trade-offs between density and parking that shape who cå live there.

    Today Regulatory Approval

    The Boston Zoning Board of Appeal unanimously approved the three-story, ten-unit rear addition with 16 parking spaces and 16 bicycle spots.

  2. Initial proposal draws neighbor backlash

    Proposal

    McGregor first proposed a four-story, 16-unit addition with no parking, prompting sharp resident opposition at a community meeting.

Scenarios

1

Addition gets built, units come on market by 2028

Likely Resolves by End of 2028

Discussed by: Boston development analysts and permit trackers

With variances secured, McGregor applies for and receives building permits from Boston's Inspectional Services Department. Construction proceeds through 2027 into 2028. The ten units—including two income-restricted ones—hit the rental market, adding housing supply near transit-oriented Dorchester.

2

Neighbors appeal or funding stalls construction

Possible Resolves by End of 2027

Discussed by: Local housing watchers, abutting property owners

Even with board approval, abutters could appeal the ZBA decision to Superior Court under Massachusetts zoning law, delaying permits. Alternately, financing or construction costs could push the timeline past original projections. The project would sit approved but unbuilt.

3

Board approval reversed on appeal

Unlikely Resolves by Q2 2027

Discussed by: Zoning attorneys who track ZBA appeals

Abutters successfully petition Superior Court to overturn the variances, arguing the board exceeded its authority by approving a project that substantially diverges from the neighborhood's existing density and height character. The project would need redesign or a new application.

Historical Context

2 moments from history that rhyme with this story — and how they unfolded.

September 2026

Neponset Avenue parking-lot apartments (2026)

The Zoning Board of Appeal separately approved replacing a parking lot at 372 Neponset Ave.in Dorchester with a four-story, ten-unit apartment building with 13 parking spaces. Both approvals came within days of each other.

Then

Two Dorchester density increases cleared the board in the same week.

Now

Boston continues approving infill housing in established neighborhoods, prioritizing housing supply over strict parking minimums.

Why this matters now

Shows the Mount Everett approval is not an outlier—the same board is consistently allowing denser projects across Dorchester.

September 2026

Granite Avenue condo building approval (2026)

The same zoning board unanimously approved a five-story, 24-unit condo building atop a vacant, tree-covered ledge between Cedar Grove Cemetery and Granite Avenue in Dorchester.

Then

The vacant lot will become a 24-unit residential building, adding ownership units to the area.

Now

Reinforces the board's pattern of approving multi-family buildingson underused or vacant lots in Dorchester.

Why this matters now

Together with Mount Everett and Neponset, this cluster shows Boston's zoning board favoring additional housing in Dorchester over neighborhood density objections.
