Heavy power is fast becoming one of the most important specs a tenant can ask for in Southern California industrial real estate. As more U.S. businesses restore manufacturing operations domestically, and as Space, Aerospace, and Defense-related uses continue booming across the South Bay, electrical capacity has moved from a line item to a deal-breaker. To complicate matters, adding power is a notoriously long and expensive process in SoCal — utility quotes, transformer lead times, and grid upgrades can delay operations by a year or more and cost hundreds of thousands of dollars. Most businesses are simply better off targeting properties that already have the power in place.
Below are some of my top picks currently available for lease in the South Bay. Each has been selected for its electrical capacity, functional specs, and overall value in today's market. Reach out to schedule a tour — I'm happy to walk any of these with you.
