Property Overview
The property at 1025 W I St, Ontario, CA 91762 is a single-story building offering exceptional flexibility for medical, office, or redevelopment opportunities. Previously occupied by Kaiser Medical Center, this vacant facility sits in a highly accessible location just off Mountain Avenue, with excellent proximity to the I-10 and SR-60 Freeways, ensuring strong regional connectivity for employees and clients. Current availability is offered under an NNN lease structure, with the owner providing tenant improvements (TI) based on lease terms and duration. The site includes 110 parking spaces, including ADA-compliant stalls, and offers significant on-site parking convenience for high-traffic medical or office operations. With a minimum lease term of 7.5 years, annual rent escalations of 4%, and redevelopment potential for multi-family or mixed-use concepts, the property appeals to both end-users and long-term strategic investors.
