Investment Insights
Based on property information with market context.
Built in 1907, 34-38 Mason Street is a three-floor brick-façade building designed for adaptive reuse. The property includes a ground-floor restaurant, a second-floor space occupied by an engineering company, and vacant office space on the third floor. Interior characteristics such as expansive windows, open floor plates, historic brick details, and generous ceiling heights support multiple redevelopment and repositioning concepts.
The building is located in downtown San Francisco and is described as being steps from Powell BART and Market Street transit lines, with access to Union Square, the financial district, and Moscone Center. Its central setting places it near prominent retail and hospitality destinations, making the site convenient for both customers and tenants.
Zoned C-3-G (Downtown Commercial General), the property is principally permitted for residential conversion. That zoning framework supports pathways that include a full conversion concept for 26 units, or a hybrid concept for 18 units plus retail, alongside partial office-to-residential transformation considerations. For buyers or operators seeking a centrally located mixed-use asset with conversion flexibility, the combination of existing income use and vacancy on the upper level provides a practical starting point for redevelopment planning.
