Medical office space · data as of September 2026
Medical office space for lease in Tustin and Parkcenter
19 buildings with 73,928 SF of medical space available across 33 listed spaces. 11 buildings publish an asking rent; no class has five or more on one lease structure, too few to call a figure typical.
Two hospitals sit within 1.1 miles of the center of the Tustin and Parkcenter trade area: Orange County Global Medical Center at 0.6 mile and Foothill Regional Medical Center at 1.1 miles.
That's straight-line distance from the middle of 19 buildings, so individual buildings sit closer or farther. Across the trade area, 11 buildings publish an asking rent, and eight post no asking rent. Most of the inventory sits on Newport Ave, Irvine Blvd and Tustin Ave: 12 of 19 buildings.
Here's the part that gets less attention. The newest of the 19 buildings went up in 1987, and 13 of them are Class C. From the real estate side, an older building can be the better deal, if the landlord pays to make the suite work. Ask what the plumbing, restrooms and HVAC can carry before you talk rent. The rent and the build-out are one negotiation, not two.
So: two hospitals sit within 1.1 miles of the center, and the newest building went up in 1987. In an older building, the allowance matters as much as the rate. What would your next suite need that your current one doesn't have?
