We are pleased to present a rare investment opportunity: a fully leased, AA+ credit tenant, medical / office property with a secure, long-term, tenant. This 58,000 sq. ft., three-story building was developed in 2014 as a build-to-suit for the County of San Bernardino and has been continuously occupied by them since. The property is leased to the County under four separate, co-terminus, lease agreements, all expiring in August 2035—providing over 10 years of remaining firm term. The tenant, the County Department of Public Health, operates the facility as the Ontario Health Center, housing four public health divisions Custom tenant improvements include: a negative pressure laboratory, four, fully equipped dental stations, 20 exam rooms, three patient waiting areas, radiology with lead-lined walls, and four additional negative pressure rooms in the clinic. • A two-ton generator (owned and included in the sale) can power critical operations during a power outage and is maintained by the County. • Enhanced security with two full-time guards during business hours and patrols covering both the building and adjacent parking structure. • Additional amenities include a 6-cubicle call center, multiple conference rooms, break rooms on each floor, over 20 restrooms, and two medication storage rooms. This facility was purpose-built to County specifications, in a location specifically selected to serve regional residents. Given the unique and costly tenant improvements and mission critical use, the County is strongly incentivized to remain beyond the current lease term. This is a secure, high-credit, long-term investment opportunity—an ideal fit for the investor seeking stable, low-risk cash flow.
