San Antonio Heights is an unincorporated, affluent community nestled in the foothills of the San Gabriel Mountains, just north of Upland and east of Claremont in Southern California. It is characterized by its winding, tree-lined streets, large custom estates, and panoramic views of the Inland Valley and mountain ranges. The real estate market here is exclusive and low-volume, primarily consisting of single-family homes on spacious lots, many with pools, guest houses, and equestrian facilities. It offers a secluded, rural-feeling lifestyle with the convenience of nearby city amenities, attracting buyers seeking privacy, space, and natural beauty without being completely remote.

The area was originally part of the Rancho San Antonio land grant in the early 19th century.
Development as a residential enclave began in the early 20th century, with many estates built in the mid-century modern and ranch-style architectures.
It remains unincorporated, governed by San Bernardino County, which contributes to its unique character and lower density compared to surrounding cities.
The lifestyle in San Antonio Heights is defined by tranquility, privacy, and a strong connection to the outdoors. The community is tight-knit but not intrusive, valuing the rural atmosphere and large property sizes. Residents often enjoy hiking, horseback riding, and gardening. There is a notable equestrian presence, with some properties featuring horse stables and direct trail access. The culture is low-key and family-oriented, with a focus on enjoying the natural setting and the stunning views from nearly every vantage point.
Typical buyers are affluent professionals, executives, and business owners seeking a primary residence that offers a retreat-like atmosphere. They often come from other parts of Southern California looking for more land, privacy, and a slower pace while remaining within a reasonable commute to major employment centers. The market also attracts empty-nesters who appreciate the peace and quiet, as well as families who value the top-tier schools and safe, outdoor-oriented environment. Equestrian buyers are a specific niche drawn to the horse-friendly properties.
The San Antonio Heights market remains a strong seller's market due to extremely limited inventory. Demand consistently outpaces the very small number of homes that come available each year. Prices are resilient and have shown steady appreciation, insulated from broader market volatility by the area's exclusivity and desirability. Properties often sell quickly, with many transactions occurring off-market or with limited exposure. The premium is placed on view properties, updated estates, and homes with unique amenities like guest houses or equestrian facilities.
Despite its prestige and prices, property taxes can be surprisingly manageable compared to similar enclaves in Los Angeles or Orange County due to its location in San Bernardino County and the Proposition 13 tax base transfer benefits for long-time owners.
Exclusive, low-density neighborhood with large, custom-built estates.
Breathtaking panoramic views of valleys, city lights, and mountain ranges.
Direct access to extensive trail systems for hiking, biking, and horseback riding.
Highly rated schools within the Upland Unified School District and proximity to the Claremont Colleges.
