1551–1561 S Vineyard Avenue presents two freestanding industrial buildings within Ontario’s highly sought-after Airport submarket, offering an exceptional owner-user or investment opportunity. Together totaling 16,257 square feet, the buildings provide ±1 acre of functional industrial real estate with a balanced mix of warehouse and HVAC-equipped office space. Each structure is equipped with 400-amp, 277/480-volt, 3-phase power, foil-insulated ceilings, multiple ground-level loading doors, and separate office and warehouse restrooms. Clear heights of 16–17 feet, natural gas availability, and IG zoning support a wide range of industrial, manufacturing, and logistics uses. The property benefits from immediate proximity to the I-10 and I-15 freeway network and sits just a quarter mile from Ontario International Airport, enhancing transportation efficiency for regional and national distribution. With no association fees and strong surrounding industrial demand, this rare pair of freestanding buildings is well positioned for long-term value.
