The San Francisco Board of Supervisors has unanimously approved plans by Brookfield Properties to transform underutilized parking lots surrounding the popular Stonestown Galleria on the city’s west side with new housing, a merchant main street and parks and plazas. The project is expected to be built in phases over about two decades.

Plans call for Brookfield to build 3,500 new residential units of four to 18 stories each, including 20% affordable and 200 units of senior housing. A new “Main Street” with retailers, restaurants, and entertainment of about 150,000 square feet will run along 20th Avenue.

“We’re thrilled with the collaboration and support we’ve received from the neighborhood and the city,” said Christie Donnelly, senior director, development, Brookfield Properties. “Stonestown as a town center will address city housing goals, enhance the location as a focal point of community activity and contribute to the long-term vitality and resilience of San Francisco. We’ve been through a lot to reach this milestone with plan iterations, a pandemic and economic turbulence. Throughout, we’ve listened, learned, and modified our project to improve it, recognizing that providing new housing is a shared responsibility with the city.”

Construction planning and city permitting will occur for two years prior to groundbreaking. The project’s master plan was created in collaboration with SITELAB Urban Studio.
