Do you believe San Francisco's downtown office market is recovering and will remain a desirable location?

The Sobrato Organization has completed the renovation of the historic One Harrison office building in San Francisco. The firm now seeks a single tenant to lease the 180,000-square-foot waterfront property as a corporate headquarters.

Why it matters

The project represents a strategic move by the developer to secure and modernize prime waterfront real estate in San Francisco. By creating a custom headquarters space, the company aims to capitalize on demand for high-end office environments in the city.

The six-floor, 180,000-square-foot property was originally constructed in 1918. The renovation included full HVAC electrification and the addition of an outdoor roof deck.
