The community is home to less than a dozen homes and the former offices of the John Swett Unified School District. Originally a company town for management and refinery workers at the Selby Smelter, American Smelting and Refining Company. Tormey is located astride old U.S. Route 40, now San Pablo Avenue. Old County Road offshoots from it and at the end there is a water reservoir. The former Southern Pacific Railroad and now its new owner since 1996, the Union Pacific Railroad, skirts the bayshore side of Tormey. In the 1940s and ’50s the Tormey Store served many of the grocery needs of the residents. The Hogg family managed the store with its single gasoline pump for many years.

The town is named for Patrick Tormey, who purchased the property from the Ygnacio Martinez Rancho El Pinole estate.
