Danville is an affluent town in the San Ramon Valley of Contra Costa County, tucked at the foot of 3,849-foot Mount Diablo and threaded by the Iron Horse Regional Trail. Once wheat and fruit-orchard country settled by gold-rush brothers, it is now one of the highest-income communities in the United States, with a preserved 1891 railroad depot at its walkable downtown core. Nobel Prize-winning playwright Eugene O'Neill wrote his greatest works here at his Tao House retreat.

About Danville

Also known as. Heart of the San Ramon Valley. The 94506 (one of America's wealthiest ZIP codes). Town motto: "Live Locally".

History. The valley was home to Native Americans who camped on Mount Diablo in summer; the land later became part of Mission San Jose grazing lands and the Mexican-era Rancho San Ramon, granted to Jose Maria Amador in 1834. Brothers Daniel and Andrew Inman arrived from Iowa in 1854, and after success in the gold fields bought roughly 400 acres of San Ramon Valley farmland, building a home and blacksmith shop that seeded the town. A town center formed around 1858, and the post office opened in 1860 with Henry W. Harris as first postmaster. A Southern Pacific Railroad spur line reached Danville in 1891, shifting the local economy from wheat farming toward fruit and nut production. Danville's population grew from 2,120 in 1940 to more than 40,000 by 2000, and residents voted to incorporate as a town on July 1, 1982.

Local economy. Danville is an affluent bedroom community; the 94506 ZIP code was ranked the 14th-wealthiest in America by Business Insider. It ranks as one of the highest-income places in the U.S. among communities of 40,000-plus residents. Median household income reached about $223,206 (2023), with roughly 78% of households earning six-figure incomes. The town's identity centers on preserved small-town downtown retail, dining, and professional services rather than heavy industry.

Culture and community. Nobel Prize-winning playwright Eugene O'Neill lived at Tao House from 1937 to 1944, writing The Iceman Cometh and Long Day's Journey Into Night there. The Fourth of July parade draws over 40,000 people each year, and the Lighting of the Old Oak Tree (LOOT) happens the Friday after Thanksgiving. Other signature events include Hot Summer Sundays classic car shows and the Devil Mountain Run (10k/5k/1-mile) race. Notable people tied to Danville include NBA star Draymond Green, NFL tight end Zach Ertz, soccer's Chris Wondolowski, Baseball Hall of Famer Joe Morgan, Motley Crue's Vince Neil, and actress D'Arcy Carden.

What makes Danville distinct. Longtime and former residents include Billy Beane (the Oakland A's executive of Moneyball fame), Chesley "Sully" Sullenberger (pilot of the 2009 Hudson River landing), and U.S. politician Adam Schiff. Once a Republican stronghold, Danville flipped politically: Barack Obama was the first Democratic presidential candidate to win the town in 2008, and Joe Biden carried it by nearly 29 points in 2020. The town motto is simply "Live Locally," reinforcing its preserved small-town, low-rise downtown character despite Bay Area wealth.
