Welcome to Ontario

Ontario's commuter-friendly location in southwestern San Bernardino County, California offers residents easy accessibility to major businesses in Irvine, downtown Los Angeles and Long Beach. The city's suburban lifestyle is enhanced by its array of family-friendly parks with basketball and pickleball courts, sports fields, playgrounds, swimming pools, walking paths and other amenities. A local favorite for outdoor recreation is the 150-acre Cucamonga-Guasti Regional Park, which features two lakes for fishing, plus a swim complex with water slides and splash pad. For dining, shopping and socializing, enjoy Downtown Ontario's pubs, great restaurants and popular retail stores, as well as special community events. Ontario also offers wonderful opportunities for arts and culture, with the Museum of History and Art, and the Chaffey Community Museum of Art at the top of the list. Other major Ontario destinations include:


  • Toyota Arena. As the Inland Empire's largest arena, this venue hosts 125+ events annually, including concerts and family shows — and it's home to the Ontario Reign, Empire Strykers and Ontario Clippers sports teams.
  • Ontario Mills®. Offering 200+ stores, California’s largest outlet and value retail destination is the ultimate experience for shopping enthusiasts.



*Consistent with California energy regulations, new homes must be equipped with solar panels. These are not included in the posted price, but may be leased for a monthly payment, or purchased for an additional cost that may be eligible for mortgage financing. The required size of the solar system depends on several factors, including home size and climate zone. The installed solar system may reduce your monthly local electric utility company bill. For more information, see sales agent and Solar Energy System Addendum.
