San Diego Just Outscored Los Angeles on Industrial Real Estate.

Hines Research just scored roughly 1,500 industrial submarkets nationwide as part of mapping the country's $1 trillion advanced manufacturing buildout, and the results should reorder how you think about Southern California industrial real estate. San Diego landed five top-tier locations. Los Angeles landed four. The Inland Empire, the largest industrial market in the entire United States by square footage, did not appear among the metros with three or more top-tier submarkets at all.

Again, the market everyone defaults to when they think "Southern California industrial," the one with the most warehouse space in the country, got skipped over by a report specifically built to identify where the next wave of manufacturing investment should land. Meanwhile San Diego, a fraction of the Inland Empire's total footprint, out-scored Los Angeles and made a stronger showing than a market roughly four times its industrial size.

Here's what's actually happening. The Inland Empire built its reputation on scale, large-distribution centers serving the ports of LA and Long Beach, the kind of big-box space importers need to move pallets. That's still real value, and still real demand, we've written about the leasing rebound happening there. But this report isn't scoring warehouse capacity. It's scoring fit for advanced manufacturing, semiconductors, defense production, precision aerospace work, the kind of tenants who need proximity to specialized talent and existing industry clusters, not just square footage and dock doors.

San Diego has spent decades building exactly that. It's why Anduril, Neros Technologies, and other defense-adjacent manufacturers keep landing there. Segerstrom just completed a $65.5 million, 313,000 SF technology center in Santa Ana, fully leased to Anduril before it was even finished. That's not your typical warehouse tenant. That's a manufacturer who needed a specific kind of building in a specific kind of ecosystem, and Orange County had it ready.

This is a genuine shift in how to think about site selection for a specific category of tenant. If your business is straightforward logistics or distribution, the Inland Empire's scale still matters and the leasing fundamentals there are still worth watching closely. But if you're in advanced manufacturing, defense, semiconductors, or any precision production that depends on a specialized labor pool and industry proximity rather than raw square footage, defaulting to the biggest market on the map may actually be the wrong instinct. San Diego and specific Orange County and Los Angeles submarkets are proving that a smaller, denser, more specialized cluster can outperform sheer size for the tenants who need it most.

The practical takeaway if you're evaluating industrial space in the next year: match the market to what your business actually needs, not the other way around.
