What Mobile Office does

Mobile Office Inc is a privately held, Alsip, Illinois-based company founded in 1952 that manufactures, sells, rents, leases, and services mobile office trailers and storage containers for businesses in the greater Chicago metropolitan area and select counties across Illinois, Indiana, and Wisconsin. Its core product line consists of five trailer sizes — 20x8, 28x8, 32x8, 60x12, and 60x24 — built on conventional trailer and modular construction technology, complemented by storage and office containers, transportation services, field repairs, and an accessories catalog (security features, stairs/ramps, tie-downs, skirting, interior furnishings).

The company operates a sales-led, quote-based go-to-market model with no publicly disclosed pricing, engaging customers via a 'Request A Quote' website form, phone inquiries, and direct outreach. Its revenue model blends one-time sales with recurring rental and leasing streams and episodic service revenue from trailer repair and rehabilitation. The customer base is horizontal and primarily SMB, spanning construction firms needing temporary job-site offices, commercial businesses requiring overflow or transitional workspace, and — to a lesser extent — infrastructure and utility operators with field-office needs.

Mobile Office Inc has operated continuously from a single Alsip, IL depot for over 70 years under private, likely family-controlled ownership, with no disclosed funding rounds, acquisitions, partnerships, certifications, patents, or leadership changes in the input data. Its go-to-market relies on its website, Google Business Profile, Facebook page, Yelp listing, and customer testimonials, with no evidence of digital channels beyond these standard local-presence assets.
