Potrero Yard Modernization Project
The Potrero Yard Modernization Project will replace an obsolete, century-old bus yard with a modern, three-story, efficient bus maintenance and storage facility, equipped to serve the SFMTA’s growing fleet as it transitions to battery electric buses.
A modern Potrero Yard will address critical transportation issues and improve:
- Efficiency: Repair buses faster, improving Muni’s reliability
- Sustainability: Provide the green infrastructure needed for an all-electric fleet
- Future Growth: Accommodate fleet as it grows – room for 54% more buses at the yard
- Work Conditions: Improve environments, amenities and safety conditions for 800+ SFMTA staff
Learn more about the need to replace this 100+ year-old bus yard.
Public tours of Potrero Yard are usually offered monthly. Check here for our current schedule of tours:

On November 21, 2022, the SFMTA awarded the project’s predevelopment agreement to Potrero Neighborhood Collective (PNC) as lead developer. PNC will work together with the City, community and project stakeholders to further refine the Project design during the pre-development phase.
The PNC design includes a modern, three-story bus storage and maintenance transit facility, over 500 units of affordable housing for those with low or moderate incomes, and multiple opportunities for commercial retail and concessions. The project would be the nation’s first known joint development of a bus maintenance facility with housing constructed adjacent to and above– a groundbreaking approach that prioritizes a safe, equitable, and sustainable transportation system while also supporting the City’s housing goals.

The ambitious housing affordability goals are reliant on competitive City and non-City funding sources. Some of these state financing sources are highly competitive because funds are spread across the entire state, and there are many projects seeking financing every year. Should the project not secure these sources on a schedule that can accommodate the construction of the bus facility, the housing program may need to be amended.
The project is designed to support San Francisco’s sustainability, housing, and safety priorities as a Transit-First City. The project encourages public transit, bicycling and walking as sustainable alternatives to driving. Resident and public parking are not provided on-site.
- Up to 513 affordable housing units that include a mix of studio, 1-, 2-, and 3-bedroom units

- Improved pedestrian and bike infrastructure for enhanced safety and comfort
- An economic inclusion plan that prioritizes Local Business Enterprise (LBE) inclusion and local hire
- Onsite amenities such as family childcare centers, laundry facilities, and community rooms

Building Progress Program
In 2017, the SFMTA launched the Building Progress Program, a $2.3 billion multi-year effort, to repair, renovate, and modernize the San Francisco Municipal Transportation Agency's (SFMTA) aging facilities to keep the City moving and transition to a battery-electric bus fleet.
Potrero Yard, located at Bryant and Mariposa streets, is the first facility scheduled under the Program that the SFMTA will modernize and renovate.
