Prime residential development opportunity in Ontario, CA. This ±56.49-acre site is well positioned for a master-planned community adjacent to the upcoming 200-acre Ontario Sports Empire. The Property has recently been rezoned to allow a mix of high-density residential, medium-density residential, and neighborhood commercial, providing developers significant flexibility in project design, phasing, and use mix. The site is directly adjacent to an additional ±22.95-acre high-density residential site under separate ownership that is also being marketed for sale, offering a compelling opportunity for a larger-scale assemblage and cohesive development footprint. The seller is offering favorable terms, including a long escrow period to support entitlement, permitting, and city approvals. This structure provides developers flexibility and significantly reduces carrying costs during the planning phase. With strong population growth, continued city investment in infrastructure, and proximity to major regional amenities, this opportunity is well suited for forward-thinking residential and mixed-use developers seeking scale and entitlement upside.
