274 Brannan Street

274 Brannan Street

(SOLD) 274 Brannan is a six-story, 105,325 rentable square foot data center, telecommunications and office building, centrally located along the Second Street Corridor within San Francisco’s vibrant South of Market (“SOMA”) District. Built in 1923, the former Hawley Terminal Building was previously a storage facility for the Southern Pacific Railroad. 274 Brannan was converted into a telecom switching building in 1982, utilizing its ideal location to two primary fiber network loops. Offering substantial power supply, large floor plates, with load-bearing capacity for heavy equipment, transitioning to data center tenants was a natural evolution for 274 Brannan. Today, 274 Brannan is known as “Fiber Depot” and attracts a diverse group of telco and data center tenants, with the remaining space leased to office and retail tenants. Ownership completed a cosmetic upgrade in 2008. Additional upgrades were performed in 2010 to meet the increasing demand for data center space.
