Plan for 2100 Dorchester Avenue includes healthcare services, workforce development, housing, open space, and more than 2,000 permanent jobs
BOSTON — The HYM Investment Group (HYM) and My City at Peace (MyCAP) are moving forward with plans to transform the former Carney Hospital property into a large-scale mixed-use health and community campus, formally filing a Letter of Intent this week with the Boston Planning & Development Agency for the redevelopment of 2100 Dorchester Avenue.
The proposed $850 million project would redevelop the 12.8-acre site into a new “Dorchester Health Campus” centered on restoring healthcare access, expanding housing options, creating workforce development opportunities, and improving neighborhood connectivity in Dorchester.
The redevelopment proposal outlines approximately 970,000 square feet across five new buildings dedicated to healthcare, healthcare education, housing, and neighborhood-serving retail and community uses. The project architect is CBT Architects. The site is currently owned by insurance and institutional funds managed by Apollo Global Management, which previously held a mortgage on the properties.
A centerpiece of the proposal is a planned 350,000-square-foot healthcare facility aimed at addressing a major gap in local healthcare access following the closure of Carney Hospital, which left more than 167,000 residents without nearby healthcare services.
HYM and MyCAP said they are actively engaging with nonprofit healthcare providers to explore future healthcare uses for the site. Plans also include a dedicated healthcare education and workforce development building designed to support training programs and long-term career pathways in healthcare and related industries.
The project would also introduce approximately 500 residential units across three buildings, including 200 units of senior housing offering independent living, assisted living, and memory care options. Additional housing plans include 100 units of market-rate multifamily housing with potential homeownership opportunities and 200 market-rate multifamily rental units.
Developers said the project was shaped through extensive community engagement conducted throughout 2025 and 2026. According to project organizers, HYM and MyCAP held more than 35 meetings with civic associations, elected officials, neighborhood groups, community organizations, and nearby residents to gather feedback and refine the proposal.
Community input consistently highlighted the importance of restoring healthcare services on the site while also prioritizing housing, open space, and better neighborhood connectivity.
In a joint statement, Thomas N. O’Brien, Managing Partner and Chief Executive Officer of The HYM Investment Group, and Rev. Jeffrey Brown, Founder and CEO of My City at Peace, said the filing represents a significant milestone for the neighborhood and the broader redevelopment effort.
“Today’s Letter of Intent filing marks an important step forward in reimagining 2100 Dorchester Avenue as a vibrant, community-centered health and housing destination for Dorchester,” said Thomas N. O’Brien, Managing Partner and Chief Executive Officer of The HYM Investment Group, and Rev. Jeffrey Brown, Founder and CEO of My City at Peace. “This filing reflects extensive community feedback and a shared commitment to restoring healthcare uses on campus, expanding local housing opportunities, and enhancing connectivity on a site that has long been a cornerstone of the neighborhood. We look forward to beginning the Article 80 process and the continued engagement with residents, stakeholders, elected officials, and the Dorchester community.”
In addition to healthcare and housing, the redevelopment is expected to generate significant economic impact for the city and surrounding neighborhoods. According to project estimates, the development would create approximately 970 construction jobs and roughly 2,100 permanent jobs while generating more than $9 million in annual property tax benefits and approximately $9.236 million in Jobs and Housing linkage contributions.
Open space and walkability are also central components of the proposal. Nearly 54 percent of the redevelopment site is planned as landscaped or open space, including a new public pedestrian spine connecting the campus to Dorchester Park and improving neighborhood access throughout the area.
The site also benefits from multiple public transportation connections, including MBTA bus routes, the Neponset River Shared-Use Path, and the Mattapan Trolley connection to the MBTA Red Line. The Cedar Grove and Butler trolley stops are both located within approximately 0.4 miles of the property.
The filing of the Letter of Intent marks the beginning of the city review and public approval process for one of the largest redevelopment proposals currently planned in Dorchester.
