Formerly a separate town, much of the community is unincorporated surrounded by incorporated San Jose; neighborhoods between White Road and Capitol Avenue are part of a city/county agreement for annexation. James Lick High School, Mt. Pleasant High School, and William C. Overfelt High School (which are part of the East Side Union High School District), Joseph George Middle School, Ocala Middle School, and other schools in the Alum Rock Union School District serve the neighborhood. Near the center of the community is a small neighborhood commercial strip along Alum Rock Avenue at White Road.
In the 19th century and early 20th century Alum Rock was mostly fruit orchard land. During the 1940s and 1950s, developers began building housing and formed the community of Alum Rock. During that time, Alum Rock Avenue and a passenger railroad passed through the town on the way to Alum Rock Park.
In the 1980s and 1990s, the neighborhood became older and increasingly populated with Latino immigrants as "white flight" affected the area of East San Jose. Today, Alum Rock remains a distinct community separated from the rest of San Jose.
The magnitude 5.6 Alum Rock earthquake occurred just northeast of the community on October 30, 2007, the strongest to hit the region since the 1989 Loma Prieta earthquake. No significant damage or injuries were reported.
