A major housing development planned for Dorchester’s Morrissey Boulevard faces potential delays due to a legal dispute among its developers. Copper Mill, the Boston-based firm leading the project, has filed lawsuits against its investment partners POB Capital and Pactolus, accusing them of attempting to exclude Copper Mill from the venture as the project gained traction last year.

The lawsuits were filed in both Suffolk Superior Court and Massachusetts Land Court and revolve around a purchase-and-sale agreement for the property located at 75 Morrissey Boulevard. Copper Mill alleges that POB Capital and Pactolus acted to undermine this agreement after Copper Mill had successfully navigated the complex city permitting process for the 754-unit residential project.

The legal disagreement emerges at a critical time when housing affordability remains a pressing issue in Boston and the surrounding region. The city continues to experience high demand for housing, but large-scale residential developments have been limited in recent years. Stakeholders worry that the dispute could cause significant delays to the project, further impacting the availability of new housing in an already tight market.

Details regarding the specific actions taken by the investment firms or their response to the allegations have not been disclosed. The project, which aims to add hundreds of housing units to a key corridor in Dorchester, represents a significant development opportunity for the city in addressing the ongoing housing shortage.

As the litigation proceeds, the timeline for construction and completion remains uncertain. Observers note that the outcome could influence future partnerships and development strategies within Boston’s housing sector.
