U.S. affordable housing developer Mission Housing Development Corp. has started building a 157-unit affordable project at 1950 Mission Street in San Francisco, California.

The housing project will include 155 units for low-income families, with 25 percent of the units reserved for formerly homeless families.

Additionally, 40 percent of the units will be reserved for people living in District 9 or within a half-mile of the site, per the city’s neighborhood preference program.

The project, being developed by Mission Housing and U.S. real estate developer BRIDGE Housing, will cost an estimated $105 million and is expected to be finalized by late 2020.
