Rare Redevelopment Opportunity in Prime Ontario Location – 10,035 SF Building on 0.68 Acres sale with Approved Fourplex Conversion Plan Near Ontario Airport



A unique investment opportunity awaits with this expansive 10,035 square foot property situated on a generous 0.68 acre lot in the heart of Ontario, California. Originally built as a private educational facility, this structure is currently undergoing a strategic redevelopment to transform it into a fully approved fourplex residential complex which is perfectly suited for multi-generational living, institutional leasing, or income generating rentals.

The city-approved architectural plans reimagine the existing footprint into four fully independent residential units, each with its own private entry, kitchen, and laundry. Interior demolition has already been completed, and the project is ready for final permitting and construction.

Unit A: 481 SF with 1 bed, 1 bath, kitchen, living room, laundry

Unit B: 7,516 SF with 8 beds, 7 baths + powder room, dual kitchens, large dining, multiple living spaces, 3 master suites

Unit C: 865 SF with 1 bed, 2 baths, office, kitchen, living room

Unit D: 1,090 SF with 1 bed, 2 baths, office, kitchen, living room

Each unit will have separate electrical and water meters. The property also features a 240 SF detached garage, redesigned landscaping, and ample yard space with future expansion potential.

Prime location just minutes from Ontario International Airport, major freeways (I-10, I-15, 60), and key business corridors. This property offers incredible flexibility for residential rental, group housing, assisted living, foster care, or community services.

Zoned for high utility and long-term upside, this project is ideal for developers, institutional investors, or owner-operators seeking scalable residential or care-facility potential in a thriving Inland Empire location.
