Larger office trailers with more amenities and upgrades cost more to rent.

Frequently Asked Questions

What is a mobile office trailer?

A mobile office trailer is a portable, standalone workspace that can be towed to a location and quickly set up. These modular units go by names like construction trailers, site offices, and portable offices. They provide a flexible temporary office space option. Mobile office trailers can serve as:

  • A construction site office
  • Temporary office space when a company is relocating or renovating
  • A supplemental workspace during busy seasons
  • An event registration office

Office trailers are available in a range of sizes from small 8′ x 20′ units up to large customized modular buildings over 50′ long. They can be outfitted with amenities like furniture, lighting, restrooms, storage, and tech capabilities.

How much does an office trailer weigh?

The weight of an office trailer varies based on its size and construction materials, but a typical single-wide portable unit weighs between 5,000-10,000 lbs empty. For example, a common 10′ x 40′ office trailer can weigh approximately 8,000 to 9,000 lbs without any interior furnishings or equipment inside.

Larger office trailers and multi-section modular buildings weigh more, sometimes up to 50,000 lbs when fully loaded and equipped. The manufacturer provides maximum load capacity specs to ensure proper towing by a heavy-duty truck and safe installation on a level site. Weight is an important consideration when renting and transporting an office trailer.

What is the width of an office trailer?

Standard office trailers range from 8′ to 14′ wide, with 8′, 10′ and 12′ widths being the most common. Here are some typical exterior width dimensions:

  • 8′ wide office trailers – 92-96 inches
  • 10′ wide units – 116-120 inches
  • 12′ wide units – 140-144 inches
  • 14′ wide units – 164-168 inches

So a 10′ x 20′ single-wide office trailer will measure about 10′ tall x 10′ wide x 20′ long. The width has to conform to road transport regulations. Multi-section modular buildings can be expanded to 24′ wide or more by joining additional units side-by-side.

The interior width is slightly less, since the walls and insulation take up some space. Always verify the interior dimensions with the office trailer rental company if space is a concern.

The width also impacts what type and quantity of furnishings and equipment can be accommodated inside. Some mobile offices are made in double-wide trailers.
