The local angle: an industrial market run from Ontario
What the firms’ own Riverside-San Bernardino pages say about this market. Market figures are each firm’s claim, not our measurement.
- Cushman & Wakefield calls the Inland Empire “the Big Box Capital of the U.S.” and says it grew from a tertiary market to Los Angeles and Orange County into a destination of its own, because it can assemble large blocks of land for big buildings. (Cushman & Wakefield Riverside-San Bernardino office page)
- All six offices are in Ontario. Newmark, Marcus & Millichap and Avison Young all list suites at 3281 East Guasti Road. (Newmark Riverside-San Bernardino office page, Marcus & Millichap Riverside-San Bernardino office page, Avison Young Riverside-San Bernardino location page)
- Newmark says its Ontario office, established in 1985, serves Riverside and San Bernardino counties, which it calls a 28,000-square-mile mega-region chosen for manufacturing, distribution and office operations. (Newmark Riverside-San Bernardino office page)
- CBRE and Colliers list their Ontario offices on their Greater Los Angeles pages rather than on a separate Inland Empire page. (CBRE Greater Los Angeles office page (lists the Ontario office), Colliers Los Angeles city page)
