What Mobile Modular Portable Storage does

Mobile Modular Portable Storage, founded in 1979 and headquartered in Livermore, California, rents, leases, and sells ISO-standardized shipping-grade steel containers adapted for portable storage, office, and combined workspace-plus-storage use cases. The company's product portfolio covers standard storage containers in 10-, 20-, 24-, and 40-foot configurations; standard and Elite (premium) portable office containers with optional integrated restrooms; 2-in-1 office-and-storage combo units; and specialty offerings including refrigerated containers (temperature range -30°C to +30°C), insulated units, open-sided containers, and guard shacks. Adjacent accessories — furniture, locks, shelving, and lighting — are sold separately and bundled into workspace packages. Underlying construction relies on Corten steel containers compliant with ISO shipping standards, OSHA workplace-safety requirements for office units, and federal certifications (GSA contract GS-07F-0401X) for government sales.

The company generates revenue across three streams: recurring container rental (short- and long-term, the primary revenue model), outright sale of new and used containers, and hardware sales of accessories and customization options. Pricing is quote-based rather than publicly disclosed, with sales specialists configuring proposals by container type, size, duration, and customer requirements. Distribution is direct: the company employs field sales specialists, inside-sales phone teams, an online CustomerHUB portal, and its own fleet of delivery trucks and drivers — yielding typically one-business-day delivery windows in served markets. Geographic reach spans 27 states plus Washington D.C. across approximately 100 branch locations.

Customer segmentation is vertical-led and diversified across eleven industries — construction (primary), industrial/manufacturing, healthcare, education, government/military, retail, petrochemical, agriculture, data center, automotive, and events — reducing reliance on any single end market. The business is operated as a division of McGrath RentCorp (NASDAQ: MGRC), a publicly traded holding company that provides shared corporate services and balance-sheet backing. Certifications include GSA approval, Sourcewell cooperative purchasing membership, ISO container compliance, OSHA-compliant office units, and NPSA industry membership; the company is also pursuing WCAG 2.1 AA digital accessibility conformance.
