United Rentals is the perfect place to rent or buy storage containers and mobile offices big and small. We customize, build and deliver new and used office trailers, modular buildings and shipping containers for retail, healthcare, construction and more. Typical container sizes are 20 and 40, but other sizes like 10 to 48 may be available. Not only do our ground-level offices (GLO) come in a variety of customizations, but they are easy to transport from one site to the next by forklift. Plus, we offer custom modifications such as electric hookups, painting, extra doors, shelving, insulation and HVAC installation to fit your office, classroom or storage needs.
