Initial renderings have been revealed for a dense residential project at Mission Bay Block 4 East in the Mission Bay neighborhood of San Francisco. The proposal will create four hundred affordable apartments across two structures, rising 16 stories and 23 stories respectively across two phases. Curtis Development and Bayview Senior Services are the joint developers.

Full build-out of Mission Bay Block 4 East is expected to yield over half a million square feet to create 400 apartments alongside parking for 78 cars and 256 bicycles. Unit types will vary, with 105 one-bedrooms, 190 two-bedrooms, 96 three-bedrooms, and seven four-bedroom dwellings.

In phase one, the South Tower is expected to rise 160 feet tall and contain 215,570 square feet, including 139,400 square feet of housing, 22,650 square feet for parking, and 1,280 square feet of ground-level retail. The second phase will see the North Tower rise 242 feet above street level and contain around 295,200 square feet, including 201,720 square feet of housing and 23,000 square feet for parking.

The complex will provide housing for residents earning between 30 and 95% of the area’s median income. According to the project team, twenty percent of the apartments will be designated for formerly unhoused families.

Perry Architects and Y.A. Studio are jointly responsible for the design. The new illustrations show that both structures will rise from a similar three-story podium and join along Third Street with third-floor courtyards and ten-story courtyard-capped extensions. The façade scheme will emphasize the verticality of the 23-story tower, in part, by camouflaging the ten-story extension of the North Tower to match the design of the South Tower. The exterior will be clad with a mix of precast concrete, metal mullions, and perforated metal screens.

The one-acre property is located at 3rd Street between Mission Rock Street and China Basin Street. Future residents will live along the Third Street light rail and the Mission Rock master plan site.

The Office of Community Investment and Infrastructure is listed as the property owner. Swinerton and Rubecon will form a joint venture to serve as the general contractor.

  1. BUILD. THIS. NOW………

    This is great. Mission Bay needs to be taller. Enough of these six story buildings everywhere. We need a mix of height.

  3. “Renderings revealed” — meaning in six years, this project will get approved, then not be built.

    • I might be mistaken, but doesn’t affordable housing projects seem to move forward more compared to market rate projects. I might be wrong.

    • They will move as soon as they can access the right mix of funding and tax incentives. This speeds up the planning phase to meet the deadlines. Activates projects much quicker than market rate when funding is awarded, which often is not hard for these highly competent affordable projects in the Bay.
