Portable Office Buildings for Rent, Sale or Lease — Temporary and Long-Term
A portable office building is a factory-built, relocatable workspace delivered ready to use — power, lighting, climate control and finished interiors already in place. Nadler rents, leases and sells portable office buildings across most of the eastern United States, in five sizes from 528 to 2,880 square feet, typically installed within one to four weeks. Whether you need temporary modular office space during a renovation or a long-term building for a growing team, you get finished portable office space without a construction schedule.
If your project needs a wheeled, jobsite-ready unit rather than a building, see our mobile office trailers.

FAQ
Portable & Modular Office Building Questions
Answers to the most common questions about portable offices, modular office buildings,
rental options, pricing, and customization.
1) What are portable office buildings?
Portable office buildings are modular structures designed to be delivered and set up quickly.
They’re commonly used as temporary or semi-permanent offices on jobsites, campuses, and commercial properties.
2) What’s the difference between a portable office and a modular office building?
People use these terms interchangeably. In general, “portable office” often implies easier relocation,
while “modular office building” usually points to more customization, larger footprints, and more permanent-style finishes.
3) Do you offer modular office buildings for rent?
Yes—rental options are often available for short-term needs like projects, expansions, or swing space.
Availability and terms depend on size, location, and how long you need the building.
4) Do you offer modular office buildings for lease?
Yes. Leasing can be a good fit when you want predictable monthly costs and flexibility.
If you share your timeline and site details, we can point you to the best rent/lease structure for your project.
5) Are there modular office buildings for sale?
Yes. Buying is often the best choice when you expect longer use, want maximum customization,
or plan to reuse the building across multiple projects or sites.
6) Should I rent or buy a modular office building?
Renting is usually best for short timelines or when flexibility matters most.
Buying can be more cost-effective long-term and gives you more control over layout, finishes, and add-ons.
7) How much do modular office building prices typically run?
Cost depends on size, whether you rent, lease or buy, lease length, and site setup. We quote delivery, installation and removal together, so the number you approve is the number you pay. For monthly rates, setup fees and the factors that move them, see our office rental prices guide, or request a quote.
8) Can a modular unit be a standalone office building?
Yes. Modular offices can be set up as standalone buildings, including larger multi-room layouts,
depending on your site and local code requirements.
9) Do you sell transportable offices (relocatable buildings)?
Yes—many modular offices can be designed and installed with relocation in mind.
If you think you may move it later, it’s important to plan for that up front
(foundation approach, utility connections, and transport constraints).
10) Can I get a mobile sales office or temporary sales office?
Yes. Modular sales offices are a common use case—often with private offices,
a reception area, and meeting space. Tell us how many people will work there
and whether you need customer-facing areas.
11) Can I use a portable office as temporary office space?
Yes — that is the most common use: office space during a renovation, an expansion, or a project with a fixed end date. Units are delivered finished, typically within one to four weeks, and removed when the project ends. See our guide to temporary office space solutions.
12) Is a mobile office always a wheeled office trailer?
No. A mobile office trailer is a wheeled, chassis-mounted unit built to move between jobsites; a portable office building is delivered by truck and set on blocks or a foundation. Both are relocatable. The trailer moves faster between sites and the building gives more floor area per unit, from 528 to 2,880 sq ft. If you need the wheeled kind, see mobile office trailers.
