Kilroy Realty Corporation has submitted a new application to the city of San Francisco, seeking changes to its previously approved redevelopment plan for the former San Francisco Flower Market site at Sixth and Brannan Streets in Central South of Market. The move comes as the company looks for ways to move forward with the project, which has been delayed.
Originally approved in 2019, Kilroy’s plan called for constructing office buildings covering 2 million square feet. The latest application introduces several new versions of the project. All options remove a planned 22,000-square-foot child care facility and about 1,000 square feet of community space from the original proposal. The revisions also include increased parking and taller buildings.
One option would create five buildings containing about 2.6 million square feet of office or laboratory space, up to 100,000 square feet of retail space, 300,000 square feet for institutional use, and more than 800 parking spaces. Building heights in this version would range from 11 to 18 stories.
Another version uses California’s state density bonus law to propose seven buildings with a total of 3,532 homes. These structures could reach up to 500 feet tall (49 stories) and would include 100,000 square feet of retail space and over 1,800 parking spots.
A “Mixed-Use Variant” proposes five buildings up to 480 feet (47 stories), with plans for 1,242 housing units along with 1.5 million square feet of office or lab space, 100,000 square feet of commercial area, and more than 1,000 parking spaces.
The “Institutional Variant” suggests roughly 1.4 million square feet dedicated to medical or institutional use plus another 1.2 million for office and lab tenants. This version includes five buildings reaching up to 270 feet (18 stories), with an additional 100,000 square feet set aside for retail and a total of 431 parking spaces.
San Francisco continues to struggle with high office vacancy rates while facing significant demand for new housing options.
The historic flower market itself has moved operations to a new location at 901 16th Street in Potrero Hill, where it now occupies a larger facility that opened earlier this year.
