The Complete Guide to San Antonio Heights Real Estate

San Antonio Heights is an unincorporated census-designated place in San Bernardino County, located directly north of the City of Upland. The neighborhood spans price points from the mid $500,000s to over $4 million on lots approaching two acres, with no master-planned subdivisions and no two homes alike. Laura Dandoy is the #1 listing agent in San Antonio Heights since 2021 and represented sellers on the two highest-priced home sales in San Antonio Heights and Upland history.

 

San Antonio Heights is defined by large lots, fully individualized properties, a historic equestrian trail running the length of Euclid Avenue, and direct access to the San Gabriel Mountains via Potato Mountain and Cucamonga Creek trailheads. Architecture ranges from modest mid-century ranch homes to custom Italian and Spanish-influenced estates above $4 million. The neighborhood sits within the 91784 zip code and is served by Upland Unified School District for all grade levels, K through 12.

What Makes San Antonio Heights Unique

No Two Properties Alike

 
San Antonio Heights has no master plan, no homeowner association governing architectural standards, and no cookie-cutter subdivisions. Every property is the result of individual decisions made by individual owners over decades. Mid-century ranch homes sit alongside Italian-influenced custom estates on lots approaching two acres. Modest properties and multi-million-dollar estates share the same streets. That individuality is the defining character of the neighborhood.

Historic Euclid Avenue

 
Historic Euclid Avenue runs the length of San Antonio Heights with a scenic equestrian trail along its median. This is one of the few remaining working equestrian corridors in the Inland Empire. The trail connects residents to Cucamonga Creek and the San Gabriel Mountains trailhead network, including direct access to Potato Mountain and the Cucamonga Wilderness. Properties adjacent to the equestrian corridor carry a consistent premium.

Location and Access

 
San Antonio Heights is located in unincorporated San Bernardino County, directly north of the City of Upland and east of Rancho Cucamonga. The neighborhood is served by Upland Unified School District for all grade levels and benefits from proximity to the 210 Freeway, Claremont's Village amenities, and Ontario International Airport. Despite its semi-rural character and large-lot feel, the neighborhood sits within minutes of major commercial corridors and freeway access.

Pricing a Unique Property

Understanding the Market
