Boston is cutting a $50 million check from its Housing Accelerator Fund to finally get the second building of the long-planned Bunker Hill public housing overhaul out of limbo and into the ground this spring. The cash plugs a stubborn financing hole that had frozen a nine-story, mixed-income tower in Charlestown and nudges forward the next stage of a $1.4 billion remake of the 27-acre site. City officials and the development team say the money is meant to move homes into construction faster while generating returns that can be recycled into future housing projects, as reported by The Boston Globe.
Project Details
According to The Boston Globe, the new nine-story building is expected to hold roughly 266 mixed-income apartments, with about 208 market-rate units and 58 units reserved for households using project-based Section 8 vouchers. The price tag clocks in at about $176.2 million, backed in part by a $122 million construction loan from Cottonwood Group. The Globe also reports that returns from Boston's $50 million investment are slated to flow back to the Boston Housing Authority, which would reinvest them in future housing development.
Where the Money Comes From
The $50 million is coming from the Housing Accelerator Fund that Mayor Michelle Wu rolled out in 2024 to close financing gaps on already-approved projects. The fund is built to accept below-market returns so that deals that do not quite pencil for traditional lenders can still move forward, according to Boston.gov. When the mayor announced the program at Bunker Hill, the redevelopment was flagged as the fund's first official beneficiary.
Developer Partners and Design
The Bunker Hill redevelopment is structured as a public-private partnership. Leggat McCall Properties and the Joseph J. Corcoran Co. are leading the work with the Boston Housing Authority and the Charlestown Resident Alliance as key partners, and the team says every new building will meet Passive House energy-efficiency standards. The first new building in the plan, Stellata, opened in early 2025 as a six-story, fully affordable property with 102 replacement apartments and relied on mass-timber construction and prefabricated wall panels to speed up the build, according to Leggat McCall Properties.
How the Vouchers Will Work
Fifty-eight apartments in the upcoming tower will be supported by project-based Section 8 vouchers, meaning the subsidy is attached to the unit, not the tenant. Under federal project-based voucher rules, eligible households typically pay about 30 percent of their adjusted income toward rent and utilities, with the voucher covering the rest, per the U.S. Department of Housing and Urban Development. That setup gives lenders and investors more predictable cash flow projections while locking in long-term affordability for lower-income families.
Timeline and Local Impact
Suffolk Construction is expected to break ground this spring, and the development team is projecting about 18 months of construction for the nine-story building. That schedule would make it one of the largest apartment projects to start in Boston in recent years, according to The Boston Globe. Looking beyond this one tower, the broader master plan calls for replacing the aging 1940 complex with roughly 2,699 mixed-income homes in 15 new buildings that blend market-rate units with thousands of replacement affordable homes, per Leggat McCall Properties.
As the multi-year transformation unfolds, city officials, housing advocates and Charlestown neighbors will be tracking whether the public-private financing model delivers as promised, how the project-based vouchers are assigned, and if the returns from this deal actually boomerang back into more affordable housing. On the ground, construction traffic, street disruptions and any temporary relocations for remaining residents are likely to be the next flash points as the Bunker Hill rebuild finally starts to feel real.
