Rexford Industrial Realty is a publicly traded industrial real estate investment trust that operates exclusively within infill Southern California markets. Founded in 2001 by Michael Frankel and Howard Schwimmer, the company went public on the New York Stock Exchange in 2013 under the ticker symbol REXR. The founders built their business model on a proprietary research database that catalogs industrial properties across the region, providing an information advantage in identifying off-market acquisition opportunities. The company's investment strategy centers on acquiring, repositioning, and operating industrial properties in land-constrained infill submarkets throughout Southern California. The portfolio consists primarily of warehouses, distribution facilities, and light manufacturing buildings located in Los Angeles County, Orange County, the Inland Empire, and San Diego. Rexford targets functionally obsolete properties acquired from private owners and family enterprises, executing value-add repositioning that includes upgrades such as increased clearance heights, dock-high loading additions, and yard reconfigurations. The company serves a diverse tenant base across e-commerce, third-party logistics, wholesale distribution, and manufacturing sectors. Properties are concentrated in submarkets including the Greater San Fernando Valley, Inland Empire West, Central Los Angeles, and Orange County coastal markets.
