Rare freestanding ±13,016 SF warehouse and office building on ±0.75 acres (±32,670 SF) in the heart of Fontana's Southwest Industrial Park. With roughly 60% of the site as fully fenced, concrete-paved yard, this is a true owner-user opportunity offering secured outdoor storage, truck staging, and trailer parking that's increasingly scarce in the IE West submarket. The building delivers strong loading flexibility for its size: three (3) 14' x 14' grade-level doors plus one (1) exterior dock-high truck well, supporting manufacturing, distribution, contractor, or heavy storage uses. With 15' minimum clear height and a durable concrete floor, the building is built to handle demanding operations. Positioned minutes from I-10 and I-15, just 5 miles to Ontario International Airport, 14 miles to the BNSF San Bernardino intermodal facility, and within reach of the Ports of Los Angeles and Long Beach, the property offers the connectivity that drives Inland Empire demand. Ideal for an owner-user seeking SBA-financeable real estate with rare excess yard in one of Southern California's most supply-constrained markets.
