What Site Prep Is Needed Before a Mobile Office Trailer Is Delivered?

If you plan to do any actual work in your mobile office trailer – and hope to keep the office workers safe – you first need to prepare the site. In addition to hooking up power, water, and data lines, this means ensuring the space and ground conditions are adequate for your needs. In this article, we look at the site prep needed before your mobile office trailer is delivered.

Prepping for Delivery of Your Mobile Office

Whether you're renting a mobile office trailer or moving one you already own, you must first ensure the site is ready for delivery. If you're renting, the vendor may send an inspector to determine whether the ground is level. However, ask your supplier to be sure, as the responsibility may fall on you.

If you're doing it yourself, start preparing the site by removing any debris or vegetation from the area. And don't forget to look up; overhead branches and utility wires may cause an issue if they're too low. Determine your office trailer's dimensions to ensure you have adequate space.

For reference, this is the amount of clear space you'll need for a standard 40' office trailer:

  • 20' vertically, for the office itself
  • 12' horizontally, for the office itself, plus an additional 5' for maneuvering the trailer into position
  • Around 100' to 120' for the trailer making the delivery

In addition, the ground needs to support the trailer delivering the mobile office. Typically, these vehicles weigh in at around 30,000 pounds. A stone-paved surface is best, but asphalt, cement, and gravel should also work.

If your site has a soft surface, such as grass or loose soil, you need to prepare it to handle the weight of your mobile office trailer without sinking. You may place your trailer on top of piles of hardwood or railroad ties. You may also lay down asphalt paving or a bed of concrete or gravel.

How Much Does it Cost to Rent a Mobile Office Trailer?

Cost varies according to size, add-ons, region, and more. In addition to monthly rental fees, you need to budget in for delivery, setup, and removal. The following prices reflect monthly rental rates.

  • A small trailer measuring 8' X 20' costs between $100 and $200 per month, on average
  • A trailer measuring 10' X 40' averages between $150 and $300 per month
  • A single-wide trailer measuring 12' X 60' averages between $300 and $500 per month
  • Delivery and setup has an average cost between $1,000 and $1,500
  • Removing the trailer costs between $300 and $1,000 on average
  • A trailer skirt costs around $500 to $800
  • Adding steps to your trailer rental costs an additional $20 to $50 per month, per set of stairs
  • Hiring a plumber to connect the trailer to city water and sewer costs between $200 and $400 on average

Unless you plan to keep the trailer for years, leasing or renting is nearly always the more economical option. Even a large trailer only costs around $6,000 to lease per year, with smaller ones coming in at around $3,600 for a year-long lease. In contrast, buying a mobile office trailer outright sets you back anywhere from $20,000 to $40,000 on average. That purchase price climbs quickly as you add accessories such as windows, light fixtures, and doors.

Additional Site Prep Considerations for a Mobile Office Trailer

Requirements vary by state and county, so check the building codes and zoning requirements in your area. For example, you may need concrete footers for a mobile office trailer. You can find this information on your state government's website, but you can also talk to your vendor.

The site needs to be staked and marked for utilities, as well, with hookups that comply with local regulations. This needs to occur before delivery.

Finally, you must make the site accessible for employees, visitors, vendors, etc. This includes space for parking and a driveway that can accommodate deliveries (such as of the trailer itself). Don't forget ADA requirements, such as handicap-accessible ramps.
