900 Sansome is a historic 28,863-square-foot building in San Francisco’s Northeast Waterfront Historic District, originally constructed in 1927 as a public parking garage. The proposed renovation will convert the two-story structure into modern office space, featuring a new elevator, upgraded building entrance, and improved interior layout, while preserving its historic character. The project includes replacing vehicle ramps with concrete flooring, updating first level windows to match the second story, and redesigning the façade with a new entryway and awning. Offered for sale at $18,500,000 as-is—with an option for a seller-built tenant improvement—900 Sansome is also available for lease at $83/PSF FS for office use or $36 NNN for an improved auto-related tenant.
