What Mobile Modular Management Corporation does

Mobile Modular Management Corporation is a nationwide provider of prefabricated modular buildings available for rent, lease, or purchase, operating as a core brand of McGrath RentCorp, Inc. (NASDAQ: MGRC). Founded in 1979 and headquartered in Livermore, California, the company serves education, construction, government, commercial, medical, industrial, religious, and retail end markets across all 50 U.S. states through 132+ branch locations, with a workforce in the 251–500 range. Its customer base spans enterprises such as Comcast, nationwide contractors like VC Construction, charter school networks including Green Dot Public Schools, and government/military buyers accessible via GSA and Sourcewell contracts.

The core technology is off-site prefabricated construction with on-site assembly, producing a product portfolio that includes single-wide and double-wide mobile offices, multi-module office complexes (nPlex/vPlex), portable classrooms (Campus Maker Hybrid and ModPod, with configurations up to 9,100 sq ft), portable restrooms, modular kitchens and dining facilities, dormitory/workforce housing, and the specialty DropBox blast-resistant buildings for petrochemical sites. Supporting platform features include the 3D Building Visualizer for online customization, Mobile Modular Plus for turnkey add-on services (furniture, air care, decking, awnings, site preparation), and solar-powered EV charging stations for remote deployments. Sub-brands—OfficeMaker, Campus Maker, DropBox, Mobile Modular Plus, ModPod, and nPlex/vPlex—structure the lineup across vertical-specific applications.

The business model combines subscription rental revenue (month-to-month through multi-year leases with 30-day billing), one-time sales of new and used buildings, a rent-to-own pathway, and bundled professional services through Mobile Modular Plus. Pricing is quote-based rather than publicly disclosed, with used inventory ranging from approximately $7,595 to $225,000 depending on size, type, and condition. Go-to-market blends direct enterprise field sales with regional phone coverage, an inside-sales CustomerHub portal for account management, a self-serve e-commerce channel for browsing live inventory and purchasing used buildings, and government-procurement access via GSA and Sourcewell contracts. Parent McGrath RentCorp reported Q4 2025 revenue of $257 million and issued 2026 full-year guidance of $945M–$995M, alongside its 35th consecutive annual dividend increase.
