Medical office space · data as of September 2026
Medical office space for lease in Kearny Mesa
17 buildings with 144,490 SF of medical space available across 56 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.
Kearny Mesa sits in the middle of San Diego's hospital map. Sharp Memorial and Rady Children's sit on adjacent campuses near Frost Street at the south end of the neighborhood, and Kaiser Permanente's San Diego Medical Center opened on Clairemont Mesa Boulevard in 2017. That concentration keeps referral traffic, imaging and lab services close, which is why specialists who want to be near those campuses without paying hospital-campus rents look here first.
Most of the medical-capable inventory is older one- and two-story Class B and C buildings along Clairemont Mesa Boulevard, Convoy, Ruffin and the Aero Drive corridor. Surface parking is usually easier than in Mission Valley or Hillcrest, and freeway access from 163, 805, 52 and 15 lets a practice draw patients from across the county.
What to watch: many of these buildings were built as general office, so check plumbing, ADA restrooms and HVAC before assuming a suite is ready for exam rooms. Landlords here quote a wide mix of lease structures, from Modified Gross to NNN, so compare total occupancy cost rather than the headline rate.

Trade area context
Sharp Rees-Stealy Kearny Mesa is open. Sharp reported on May 21, 2026 that its 98,000-square-foot medical office building at 8975 Balboa Avenue now consolidates the Genesee, Mira Mesa and Murphy Canyon sites. It adds to a cluster of hospital campuses within about 1.6 miles of the center of the trade area.
- 78,290 residents in the ZIP areas, 14.6% of them 65 or older, 95.3% insured. Median household income runs from $99,644 (92111) to $132,534 (92123).
- Sharp Memorial and Rady Children's are adjacent campuses near Frost Street, each 1.60 miles from the center of the trade area. Kaiser Permanente San Diego Medical Center is 1.16 miles.
- Clairemont Mesa Boulevard counts 19,704 to 59,469 vehicles a day near listed buildings, and Balboa Avenue 19,788 to 50,315 (CoStar, 2026 counts).
- Frost Street counts 6,416, so the hospital blocks and the busy corridors are not the same place.
The lease read: visibility is available on Clairemont Mesa and Balboa. Near the hospital campuses, ask how patients find the suite and where they park. A great address on a quiet street is still a quiet street.
Short version: a newly consolidated Sharp building, three hospital campuses 1.16 to 1.60 miles out, and busy corridors that sit apart from them. Which of those campuses do your referrals run to today?
