Renderings have been shared for the office-to-housing conversion of 150 Hayes Street in San Francisco’s Civic Center. The proposal will produce just over a hundred units, adaptively reusing the existing structure while reskinning the facade and adding a floor. The application states construction could start as early as next summer. Emerald Fund and SDG are jointly responsible for the application.

The proposed 100-foot structure is expected to yield about 158,250 square feet, including 128,300 square feet of housing and 29,950 square feet for the two-level garage spanning the ground floor and basement. Unit sizes will vary with 55 one-bedrooms, 42 two-bedrooms, and seven three-bedrooms. Parking will include 88 vehicles and 108 bicycles.
Solomon Cordwell Buenz is responsible for the design. The exterior will be clad with a geometric bronze metal panel framing protruding over Hayes Street, with additional facade materials to include dark stone/concrete panels and floor-to-ceiling windows.

The application intends to invoke the recently adopted Downtown Revitalization Financing District. The program provides “annual incentive payments to eligible commercial-to-residential conversion projects in downtown San Francisco using tax increment financing,” according to the city’s website. None of the housing will be deed-restricted as affordable, invoking San Francisco Planning Code Section 406(j).
The 0.45-acre property is located along Hayes Street, between Polk Street and Van Ness Avenue. Future residents will be a block away from City Hall, close to the Bus Rapid Transit section along Van Ness, and just a few blocks away from the Civic Center BART Station.

SDG is a San Francisco-based investment firm founded by Jack Sylvan, a former Senior Vice President at Brookfield Properties. Emerald Fund is a San Francisco-based real estate company founded in 1979, responsible for 37 completed projects. Among their past projects is the city’s largest-ever adaptive reuse, creating 418 units at 100 Van Ness Avenue with design by SCB. The former office tower was part of a four-building campus, including 150 Hayes Street, all occupied by the California State Automobile Association.
Construction at 150 Hayes Street is estimated to cost around $45 million, with work starting as early as June 2027 and lasting around 18 months.

Impressive. It’s still giving corporate office building, but at least it looks more contemporary. Should be good too if the trees are planted and are allowed to grow to full size.
Solidly hits the mark.
Perfect design reflecting the in-between of Hayes & Civic Center,
