Construction Site Trailers: Benefits, Pricing, & Top Suppliers

If you are starting a construction project (ie. renovations, expansions, building, or tearing down) expected to last a few weeks or more, chances are your crew will need a construction site trailer. Don’t make the mistake of starting your construction project without a temporary space on-site. Learn about why construction teams rent construction site trailers for just about any building project.

What is a Construction Site Trailer?

Construction site trailers, a.k.a. mobile offices or office trailers, are crucial temporary, portable spaces used in the construction industry. Construction workers and contractors spend a majority of their workdays (8+ hours a day) on a construction site. They often need a temporary space to manage the project, plan ahead, meet with the crew, or simply sit down, cool off, and take a break. Trailers are ideal for construction projects spanning more than a few weeks and can store construction tools and equipment. Construction site trailers are:

  • Highly flexible and functional as portable space
  • Can be customized internally/externally to suit your crew’s needs
  • Cost-effective
  • Highly secure
  • Made of high-grade steel 
  • Weather-proof
  • And more 

Key Benefits of Using a Construction Site Trailer

It’s no surprise that construction teams use construction site trailers for almost any project since they provide construction crews with tons of benefits.

Safety and Security

Construction site trailers ensure your workers and equipment will remain safe on the job. First of all, construction site trailers provide a safe, clean space where your crew can go to take care of injuries, use a first-aid kit, or take a break while on the job. This can be essential in hot summer months where your crew is exposed to the heat for hours at a time.

Additionally, construction site trailers are typically built using high-grade, weather-proof steel and advanced locking mechanisms. This ensures your equipment and tools will remain locked up and secure to prevent theft when you are off the job. You also won’t have to worry about weather damage should inclement weather occur. 

Temporary and Portable

Since construction site trailers are portable, temporary spaces, they provide instant space to construction crews at their jobsite. Your team simply rents the trailer from a local supplier. Then, the supplier will deliver it to your site and unload it wherever is most convenient for you. When the project is over, the supplier returns to pick up the trailer. Additionally, suppliers offer a variety of different contract lengths including month-to-month, in case you aren’t sure about the exact duration of the project.

Construction crews typically spend long hours at a jobsite. It can be very tiring to complete the job without a clean space to cool down or warm up, depending on the season. Construction site trailers can come equipped with air conditioning, heat, and ventilation and bathrooms which gives your crew a space to rest while working hard on the job. Additionally, construction site trailers are excellent spaces to sit down, meet with your team, and take care of administrative work.

Customizable and Flexible

One of the top benefits of construction site trailers is that they can be customized in many ways. Depending on your crew’s needs, trailers can be equipped with whatever your team needs to be successful at the construction site. Some popular customizations include electricity, awnings, air conditioning units, and more.


Construction site trailers provide you with everything you will need at a job site without breaking the bank! This is one of the many reasons they are so widely used by construction crews. You can rent the trailer for the duration of the project for a monthly fee. Rentals usually cost between $200-$900 monthly, depending on the contract length, trailer size, and customizations. Some suppliers offer flexible prices and discounts when you rent for longer durations.

Available Sizes and Prices

You have several different options when it comes to trailer sizes for your construction site. Note that size often impacts pricing, whether you are renting or buying. The smaller the trailer, the more affordable your rental or purchase price will be. Take a look at some common sizes and pricing here.

8’ x 20’$200 – $400 to rent per month
10’ x 44’ $300 – $500 to rent per month
12’ x 60’$500 – $700 to rent per month

Keep in mind that wider trailers (aka mid-size or double-wide trailers) are often used to set up multiple offices inside. If you are looking for just one open common space inside, you can probably choose a single-wide trailer (approx. 8’ x 20’). Also note that the longer you rent your construction site trailer, the lesser your monthly rental rate will likely be.

Included Features and Hook-ups

Construction site trailers can be equipped with a huge variety of custom features and hook-ups. Some common add-on features for construction sites include:

  • Electricity
  • Internet and WiFi
  • Bathrooms
  • Plumbing
  • Heat, ventilation, and air conditioning
  • Insulation
  • Furniture
