Hebrew SeniorLife filed plans for a new affordable senior housing development next to its existing Roslindale campus.

The senior housing operator proposed a 78-unit affordable senior housing community in partnership with the Boston Housing Authority, according to a letter of intent filed Tuesday. The project would take up an underutilized part of the company's Roslindale campus, replacing a staff parking lot.

The project would consist of 81K SF of residential development on the corner of Centre and Walter Streets. The new affordable units will be supported by subsidies from BHA and the Department of Housing and Urban Development's Restore-Rebuild program.

The proposed apartment building would be next to Hebrew SeniorLife's 455-unit apartment complex on Centre Street. That building includes 405 long-term chronic care and 50 long-term acute care beds.

Hebrew SeniorLife has seven facilities in Boston, Brookline, Canton, Dedham, Randolph and Revere, according to its website. The company serves 4,500 seniors throughout Greater Boston.

The senior housing operator this month opened a 54-unit, fully affordable housing project for seniors at 108 Centre St. in Brookline, Brookline News reported. The developer also worked on a 45-unit development in Randolph at the Simon C. Fireman Community. Hebrew SeniorLife began construction on that project after receiving financing in 2022.

Other senior housing developments moving forward in the area include a 150-unit, low-income senior housing development proposed in March by the Charles H. Farnsworth Housing Corp., the Boston Business Journal reported. The developer bought the site from The Home for Little Wanderers for $7.6M. It is also planning an 88-unit low-income housing development in Jamaica Plain.

Nationally, senior housing occupancy increased last quarter for the 15th consecutive quarter, to 87.4%, according to Multi-Housing News. However, new inventory growth decreased 32% from the prior quarter to just under 1,900 units.
