Do you believe San Francisco's downtown office market is recovering and will remain a desirable location?
The Sobrato Organization has completed a major renovation of the historic 1 Harrison St. office building, signaling a new attempt to lure a single occupant to the waterfront property. The developer purchased the 1918-era building for $82.5 million in early 2023.
Why it matters
The project represents a bet on the demand for high-end, single-tenant headquarters as the city continues to navigate its downtown office recovery. It remains to be seen if the building's new roof deck and electrified systems will attract a tenant willing to take the entire 180,000-square-foot footprint.
The renovation covered a 180,000-square-foot footprint across six floors, following an $82.5 million acquisition. While the building is now move-in ready, no specific tenant or lease terms have been publicly confirmed.
The players
The Sobrato Organization
A developer with a significant portfolio in Silicon Valley and San Francisco that is targeting single-tenant headquarters.
Chase Lyman
A representative who toured the facility before the developer's 2023 acquisition.
Habitat Horticulture
The design firm responsible for the new living wall installed in the office lobby.
The details
The renovation of the 1918 building included the electrification of the HVAC system and the creation of an outdoor roof deck by partially demolishing sixth-floor office space. The lobby now features a living wall designed by Habitat Horticulture, a departure from the property's previous decades of use by Gap. The Sobrato Organization plans to continue pursuing commercial acquisitions in San Francisco.
Timeline
The property was originally built in 1918.
Chase Lyman toured the property for the first time in 2022.
The Sobrato Organization purchased the building at the start of 2023.
The renovation project reached completion in late September 2026.
Across the Bay
This project continues the trend of major renovations for local commercial assets established by the company's earlier acquisitions of 808 Brannan and 180 Townsend. It marks a shift for the developer as it applies its regional investment strategy to a historic waterfront office site.
The property at 1 Harrison St. is now fully prepared to house a single corporate headquarters. Residents in the immediate vicinity should expect shifts in traffic and activity if a new major tenant moves into the six-floor building.
The takeaway
The transformation of this 1918 property highlights the ongoing effort to modernize older office inventory into specialized headquarters. Keep an eye on local real estate filings to see which company eventually signs a long-term lease for the space.
