Back

Montclair sits in the southwest corner of San Bernardino County, where the Pomona Valley meets the edge of Los Angeles County, placing it squarely within the Inland Empire region of Southern California. The city is a compact, fully built-out suburb with a population of about 37,900 and one of the higher densities in its area, reflecting its role as an affordable, transit-connected gateway between Los Angeles and San Bernardino counties. Interstate 10 forms the city's northern boundary and gives Montclair its most visible landmark: Montclair Place, a 1.2-million-square-foot indoor mall positioned just off the freeway that draws shoppers from across the valley. The center anchors a broader commercial corridor and doubles as an entertainment destination, with a dine-in cinema and family-oriented attractions alongside major retailers. Transportation has long shaped the city's identity. The Montclair Transit Center, opened in the early 1990s, combines Metrolink commuter rail on the San Bernardino Line with bus connections, making Montclair one of the eastern San Gabriel and Pomona valleys' key regional transit nodes. The city's location at the meeting point of two counties also means residents can readily reach the job centers, universities, and cultural attractions of both the Inland Empire and greater Los Angeles. Montclair's housing stock skews toward mid-century single-family homes and garden apartments on modest lots, suited to a young, diverse population. The community is largely residential in character between its commercial corridors, with tree-lined streets and neighborhood parks. For homebuyers, Montclair offers a rare combination of comparatively approachable Inland Empire housing, a genuine commuter-rail connection, and a self-contained retail base, all within a short drive of the larger employment hubs of Ontario, Rancho Cucamonga, and Pomona.

About Montclair

Real Estate & Housing

Montclair's housing character is defined by mid-century modern single-family homes on compact lots, a legacy of the city's rapid post-war suburban growth, alongside garden-style apartment and condominium communities concentrated near the transit center and commercial corridors. The streetscape is consistently residential and low-rise, with mature landscaping and a sense of neighborhood stability rather than sprawling estate living. Buyers generally find smaller footprints than in neighboring foothill communities, reflecting Montclair's role as an approachable entry point to the Pomona Valley.

Neighborhoods

Lifestyle in Montclair

Montclair functions as a regional shopping and dining destination, with Montclair Place serving as the community's commercial heart. The city's population is notably young and diverse, and everyday life revolves around family-oriented amenities, neighborhood schools, and easy access to the retail and entertainment options along the I-10 corridor. Residents benefit from the convenience of having a major mall, restaurants, and a cineplex within the city, while also being a short drive from the larger downtowns and cultural venues of nearby Ontario and Pomona.

Schools & Education

Public education in Montclair is provided by two districts: the Ontario-Montclair School District for elementary and middle grades, and the Chaffey Joint Union High School District for high school. The two-tier arrangement is common across the western Inland Empire and gives Montclair families continuity through K-12 while drawing on larger regional districts with established programs. A number of private and charter options also serve the surrounding valley, offering families additional choices.

Interstate 10 runs along Montclair's northern edge, providing direct freeway access across the Pomona and San Gabriel valleys and into the broader Los Angeles basin. The Montclair Transit Center is the city's signature mobility asset, combining Metrolink commuter-rail service on the San Bernardino Line with local and regional bus connections in a single intermodal hub.
