TheHuchiun tribe lived in the region.[8] In 1823,Ygnacio Martínez, commandant of thePresidio of San Francisco, received a land grant ofRancho El Pinole from the Mexican government. Martinez built ahacienda in Pinole Valley; this is land encompassed by Pinole Valley Park. During the 1850s, Bernardo Fernandez, a Portuguese immigrant, started a trading facility on the shores ofSan Pablo Bay. He builtFernandez Mansion, a historic building that still stands today at the end of Tennent Avenue. From these early beginnings, a small but thriving community developed into the city of Pinole.
The settlement's growth was stimulated by construction of theSouthern Pacific Railroad in 1878 and the establishment of theCalifornia Powder Works in nearbyHercules. During this period, the city had an active waterfront and was a regional hub of commerce and banking. The first post office opened in 1878 when the railroad reached the community.[9] The City of Pinole wasincorporated in 1903.[9]
During the post-World War II boom, Pinole and the surrounding area grew rapidly. Construction ofInterstate 80 in 1958 stimulated developers to build new housing to satisfy demand, and the town evolved as a suburbanbedroom community within the San Francisco/Oakland commuter belt. Much of its original industry was displaced during this time, and the town became predominantly residential.
Today, the town is locally known for its "big-box store" shopping district along Fitzgerald Drive, andPinole Vista Shopping Center, which is contiguous withRichmond'sHilltop area. The downtown area still retains much of its turn-of-the-century building stock. The city's development agency is working to preserve this historic area as a tourist and community destination.
