We Know Danville—And We Know What Your Home Needs

Danville is one of California’s most desirable communities—a picturesque town of approximately 43,500 residents nestled in the heart of the San Ramon Valley. Named “California’s safest town” five years running (since 2018), Danville offers an exceptional quality of life that attracts families, professionals, and retirees alike. It’s one of the few incorporated municipalities in California that officially uses “town” instead of “city” in its name—a distinction that reflects its small-town character.

The town’s setting is stunning. Las Trampas Ridge rises to the west while the Diablo Range frames the east, with majestic Mount Diablo (3,849 feet) providing a picturesque backdrop. Sycamore Creek winds through town, draining the mountain slopes. The Iron Horse Regional Trail—a converted railroad corridor now serving as a beloved 10-foot-wide bike and hiking path from Livermore to Concord—passes directly through Danville.

Danville’s history runs deep. The Bay Miwok people first inhabited the valley, living near creeks and camping on Mount Diablo during summer months. The area later became grazing land for Mission San José and then part of Rancho San Ramon, a Mexican land grant awarded in 1834. Brothers Daniel and Andrew Inman arrived during the California Gold Rush, using their mining earnings to purchase 400 acres in 1854. They built a home and blacksmith shop, establishing the foundation of today’s community. The name “Danville” honors Daniel Inman—though some accounts suggest it also pays tribute to Andrew’s mother-in-law, who hailed from Danville, Kentucky.

The Southern Pacific Railroad arrived in 1891, transforming Danville from a small farming settlement into a thriving community. John Hartz sold land for the Danville Depot and subdivided lots along what became Hartz Avenue—still the heart of downtown today. The historic Danville Hotel (originally built in 1858, rebuilt in 1927, and restored in the 2010s) anchors the charming downtown district.

Danville remained farm country well into the 1940s, with the entire valley counting just 2,120 residents in 1940. The construction of I-680 in the mid-1960s changed everything. Population leaped from 12,700 in 1960 to 26,500 by 1980—with 82% of those residents having arrived after 1970. Citizens voted to incorporate in 1982, gaining local control over their community’s future.

Today’s Danville features diverse neighborhoods reflecting its growth over decades. Downtown Danville showcases historic buildings converted to shops, restaurants, and galleries. Sycamore Valley on the east side offers beautiful homes on large lots with a rural feel. Greenbrook features well-preserved mid-century modern homes, including Eichler designs. Montair and Cameo Acres represent the first wave of post-war development.

Quick Homeowner Tip:

Check your air filters every month—especially during summer when your AC runs more frequently in Danville’s warm weather. A clogged filter makes your system work overtime, drives up energy bills, and shortens equipment life. And if you notice electrical warning signs like flickering lights, warm outlets, or burning smells—call a licensed heating and air conditioning electrician right away.
