San Francisco’s sluggish economic comeback is gaining traction, and now, another developer is reviving a long-stalled megaproject that was shelved during the pandemic. Kilroy Realty Corp. is seeking to reboot its 2 million-square-foot office campus in the city’s Central SoMa neighborhood, which is planned to rise on a collection of properties centered around the former San Francisco Flower Market site at Sixth and Brannan streets. To do so, the project could change shape significantly: Kilroy filed an application with the city Friday to modify the current design, which features three office buildings ranging from 11 to 17 stories high. The application shows that the developer has pitched four versions of the project approved in 2019 — with mixes of housing, office, lab and institutional space on the table — seemingly trying to stay flexible as the future remains uncertain.

In all four variants proposed for Kilroy’s Central SoMa project, a 22,000-square-foot child care facility and roughly 1,000 square feet of community space that were promised as part of the original project have been nixed, while the amount of parking that the project would provide has been significantly increased, as have building heights.

One version of the modified project for which Kilroy is seeking approval remains office-heavy: The developer has proposed constructing five new buildings containing roughly 2.6 million square feet of office or lab space, up to 100,000 square feet of retail space, 300,000 square feet of institutional space and more than 800 parking spaces. The buildings in this version of the project would range from 11 to 18 stories. A second version of the project, referred to as “Residential Variant 1,” would involve the developer using the state density bonus law to build 3,532 new homes across seven buildings with a maximum height of 500 feet, or up to 49 stories. The housing project would also include 100,000 square feet of retail space and more than 1,800 parking spaces. The project also has a “Mixed-Use Variant,” which would feature about one-third of the number of units planned in the residential variant, along with 1.5 million square feet of office or lab space, 100,000 square feet of commercial space and more than 1,000 parking spaces across five buildings rising as high as 480 feet, or 47 stories. The final version of the project is known as the “Institutional Variant.” It proposes the construction of roughly 1.4 million square feet of medical or institutional space, 1.2 million square feet for office and lab tenants, plus retail space and parking, across five buildings rising to a maximum height of 270 feet, or 18 stories.
