Lab-ready inventory is structurally tight. ****What is the defense tenancy concentration?**** : Material. Northrop Grumman, General Atomics, Booz Allen, and a deep cluster of defense contractors anchor Class A demand around Sorrento Mesa and Kearny Mesa. ****Is downtown San Diego recovering?**** : Slowly. The Campus at Horton reposition is the single largest downtown leasing event of the cycle. Broader recovery requires sustained demand diversification. ## Editorial provenance Reviewed by [**Miriam Hollander**](/about/authors/miriam-hollander) — Lead market analyst. Last updated 2026-04-15.
