Overview

This industrial/manufacturing warehouse includes heavy power and a 28-foot clear height. The building is equipped with three interior truck wells and one street-level door for loading and distribution, along with a metal post-and-beam mezzanine that provides approximately 1,320 square feet of additional storage area. Office space is distributed across two floors, featuring a first-floor layout with reception, five offices, a conference room, break room, an office/machine area, and three restrooms, plus a second-floor office plan with an executive office, seven offices, a large conference room, break room, and two restrooms. Recent exterior and building updates include a new roof, interior/exterior paint, asphalt replacement, and landscaping.

The property is centrally located off the I-10 with freeway exposure, positioned west of the 15. It is less than four miles to Ontario International Airport, with Milliken Ave listed as the cross street.

For tenants and operators, the combination of high-clear warehouse space, loading capabilities, and substantial on-site office support makes this facility practical for industrial users that need both production or storage space and a functional administrative presence on-site.
