Boston Mayor Michelle Wu on Monday introduced a proposal for temporary tax abatements aimed at accelerating the construction of market-rate housing projects that have stalled due to financing challenges. The measure targets four large-scale developments already approved by the Boston Planning and Development Agency (BPDA), with the goal of starting construction on at least 1,400 new residential units by 2027.

The proposed tax relief would provide approximately $31.5 million in savings to developers of the identified projects, which include a 408-unit, 16-story building near the Sullivan Square Orange Line station in Charlestown; a 318-unit, 16-story development on Pratt Street in Allston; a 333-unit project along Leo Birmingham Parkway in Brighton; and a 341-unit mixed-use complex near Boston Landing, adjacent to the Massachusetts Turnpike.

Mayor Wu’s plan focuses on residential developments with 100 units or more that have experienced delays due to financing constraints, offering “targeted, time-limited tax abatements” to help unlock capital and spur construction activity. City officials characterized the proposal as part of a broader strategy to address Boston’s slow-moving housing pipeline by providing measured financial incentives to market-rate developers.

The BPDA board is scheduled to review the proposal in October, following a 30-day public comment period. Advocates and city representatives noted that the mayor’s approach signals a willingness to collaborate with developers on solutions that promote increased housing supply amid the city’s ongoing affordability and inventory challenges.

If approved and implemented, the tax relief could expedite the delivery of a substantial number of market-rate units, contributing to Boston’s efforts to meet rising demand for housing in multiple neighborhoods across the city.
