San Diego's largest employer is the U.S. Navy, with more than 40,000 sailors, marines, civilians, and contractors tied to San Diego Naval Base, followed closely by UC San Diego at roughly 18,900 to 38,700 employees depending on how affiliated medical staff are counted. Health care and social assistance is the single largest civilian industry, accounting for over 208,000 jobs and 13.6 percent of the workforce, while professional, scientific, and technical services adds another 183,000-plus jobs, much of it in biotech and defense-adjacent engineering.

Qualcomm remains the region's flagship technology employer with over 10,300 local staff, and Scripps Health employs more than 12,300 across its nonprofit hospital network. Venture capital has flowed heavily into San Diego in 2026, with the region pulling in over $3 billion in the first quarter alone, led by aerospace and defense firm Shield AI. The city also runs 18 separate business improvement districts and 15 redevelopment project areas, reflecting a patchwork of distinct commercial corridors rather than one dominant downtown core.

With median home prices topping $1.07 million and a workforce split between military families, biotech researchers, and hospitality staff, San Diego households and institutions generate steady demand for plumbers, electricians, dentists, and HVAC contractors across a wide geographic footprint of naval, university, and hospital-adjacent neighborhoods rather than one central business district.
