A long-delayed, fully affordable housing project in downtown Mountain View has finally moved from paperwork to shovels in the ground, as city officials and developers celebrated a ceremonial groundbreaking this week. The project, called Corso, will turn a 1.5-acre public parking lot near the civic center into a five-story building with 120 apartments for low- and very-low-income households. It is designed to bring family-sized homes, on-site services and dedicated community space right into the core of downtown.
Officials Mark the Milestone
City and county leaders, developers and housing advocates gathered at the site Wednesday to mark the start of work. Santa Clara County Supervisor and former Mountain View mayor Margaret Abe-Koga was among the speakers, saying she looked forward to welcoming new neighbors and providing "hope, stability and opportunity" for the 120 future households. The ceremonial event and remarks were reported by Mountain View Voice.
What Corso Will Include
According to project documents and county planning files, Corso will include 18 studios, 41 one-bedroom units, 31 two-bedroom units and 30 three-bedroom units. The plan reserves 20 apartments for rapid rehousing, 15 units for residents with intellectual and developmental disabilities and 10 units as permanent supportive housing. Common spaces will include a lobby, a multipurpose community room, a teen lounge, a central courtyard and a bicycle lounge, as outlined in a project review from Santa Clara County.
How the Financing Came Together
The financing stack blends multiple public and private sources to close a sizable gap that had stalled the project for years. A City Council report shows about $23.45 million in city funding committed to Corso, while county housing-bond documents record nearly $19.75 million in county loans for the development. Those public contributions, combined with tax-credit equity and private financing, are what developers say finally made construction possible.
Timeline and Partners
Developer materials state that construction began in March 2026, with the community expected to open to residents in early 2028. Alta Housing lists partners including the Santa Clara County Housing Authority, Destination: Home Silicon Valley, Wells Fargo and Freddie Mac. Related California's project page identifies Related California Construction as the builder and notes a target of LEED Gold certification. Alta and Related are jointly developing the site and plan to coordinate on-site resident services with county programs.
Why It Matters
Affordable housing advocates say Corso stands out for offering deeper income-restricted units in a high-cost downtown market and for keeping larger, family-sized apartments close to transit. At the groundbreaking, Mayor Emily Ann Ramos said the city is "building the future of Mountain View one project at a time," according to Mountain View Voice. With permits in place and phased construction underway, the developers are working toward that early 2028 opening target.
