Fontana Medical Plaza, located at 8110 Mango Avenue in Fontana, CA 92335, is a ±25,700 square-foot medical office building situated on approximately ±2.63 acres of land. This fully improved facility is ready for immediate occupancy, licensing, and operation, presenting a unique owner-user medical office opportunity. The property is ideally suited for a variety of medical uses, including primary care medical group offices, an urgent care clinic utilizing the existing infrastructure, or a potential surgery center. From 1988 through May 2025, the building successfully operated as a primary care medical group practice featuring pediatrics and OB/GYN specialties. Following Optum’s acquisition of the prior medical group in 2022, changes in physician retention led to a lease non-renewal.
The property also includes a previously successful urgent care setup with a separate patient entry, waiting room, and physician/staff entrance, all of which remain in place. The building is well-appointed with ready-to-use improvements, including 40 exam rooms, 19 offices, six restrooms, three patient entrances, three lobby/waiting areas, three registration counters, five nurse stations, one kitchen/break room, and a large conference room. Additional features include 150 parking spaces (including ADA), a parking ratio of 5.84:1,000 SF, and fire sprinklers throughout. The property currently has three existing tenants—a dentist, a podiatrist, and a pharmacy—and has undergone material ADA parking compliance improvements. Zoned Gateway Core, the property falls within the city’s Downtown Core Project area, designed to establish strong gateways to Downtown Fontana, encourage mixed-use residential and commercial development, and support efforts to revitalize the downtown district.
