- Project to meet Passive House standards in one of Massachusetts’ priciest markets
43 Affordable Units Coming to 24 Webster Avenue
MassHousing and Just A Start have closed financing for a six-story affordable housing development in Union Square that will replace a vacant commercial building. The project will deliver 43 new deeply affordable rental homes in one of the most expensive neighborhoods in the Commonwealth.
What the Capital Stack Means for Affordable Housing Delivery
What Passive House Standards Mean for Operating Costs
The building will be constructed to Passive House standards, emphasizing energy efficiency and lower long-term operating expenses. For affordable housing operators, lower utility costs mean stronger long-term asset sustainability and better tenant affordability.
What This Means for Somerville’s Housing Pipeline
Union Square has rapidly evolved with transit access and mixed-use density, driving up rents and land values. Delivering 43 deeply affordable units in this submarket reflects continued state-level commitment to preserving affordability near job centers and transit corridors. For developers and lenders, the deal reinforces that affordable housing in Massachusetts remains financeable when layered with tax credits, agency support, and institutional construction debt. In high-barrier Boston-area markets, public capital continues to be the key unlock for new supply.
