Medical office space · data as of September 2026
Medical office space for lease in Fullerton
11 buildings with 48,578 SF of medical space available across 22 listed spaces. Seven buildings publish an asking rent; no class has five or more on one lease structure, too few to call a figure typical.
Providence St. Jude Medical Center sits 0.5 mile from the center of the Fullerton trade area.
Those are straight-line miles, measured from the middle of the 11 buildings with space listed, which hold 48,578 SF across 22 spaces. Of the 11 buildings, 5 sit on Harbor Blvd. Across the trade area, seven buildings publish an asking rent, and four post no asking rent.
One more fact changes the read. Only 2 of 22 listed spaces are 4,200 SF or larger. From the real estate side, scarce large space is a reason to ask about two adjacent suites as well as one big one. Ask each landlord what's contiguous (next to each other on the same floor), not just what's listed.
So: Providence St. Jude Medical Center sits 0.5 mile out, and only 2 of 22 spaces are 4,200 SF or larger. Size, not price, is the constraint for a bigger practice here. How many exam rooms will your practice need at the end of the next lease, not the start?
