How long can you use a mobile office?

The typical length of use can range from several weeks to a few months. They have a life expectancy of 1-5 years.

Should I rent or buy?

It depends on how long you need the trailer. If it’s 24 months or less, renting is more cost-effective. If you need the trailer for more than 24 months, consider buying. Depending on the supplier, the break even number to lease vs. purchase is usually around 24-36 months. Some suppliers even offer a lease-to-purchase option. Ask around.

Should I buy new or used?

If you want to save money, buying used is the way to go. Just because a mobile office is used doesn’t mean the trailer is in bad shape. The condition of used trailers can vary widely, depending on how well the previous owner maintained it. If you want to maximize the trailer’s life expectancy, you should buy new.

How much does a mobile office cost?

The price to purchase an office trailer ranges anywhere from $15,000 to $45,000. The price to rent a mobile office trailer ranges from $200 to $900 per month.

How long is a typical rental contract?

Rental contracts usually last 3 to 6 months, but some are as short as two months and as long as 2 years. It depends on the supplier and their specific contract terms.

Can I go month to month?

Yes. Most suppliers offer a month to month contract with a 30-day termination notice.

How long does delivery take?

It usually takes around 7 to 10 days to deliver an office trailer. Depending on your area, some suppliers can get it to you in as quickly as 24 hours.

Ground prep for mobile office delivery

Is site prep required?

Some basic site prep is usually needed. You want the area to be flat, dry and free of debris or rocks. Additional things to consider: can a flatbed truck and trailer fit through the gate/entrance to your property? Are there any low-hanging branches that will affect delivery? Is your site prone to flooding? Any details like these should be communicated to the supplier before delivery is arranged.

Do I need a permit?

In most cases, NO. Because mobile office trailers are considered temporary structures, you do not usually need a permit to keep the unit on your property for a brief amount of time. However, these rules can vary by area. A general rule of thumb: property that is in an urban, highly trafficked, or residential area will have stricter permit requirements than property in a rural or low traffic area. Contact your local authorities to determine specific requirements. What you don’t want is to be slapped with a fine because you didn’t ask.

Can I get insurance for theft or damage?

Some suppliers offer a liability waiver for an additional fee. If this is something you’re interested in, be sure to ask this upfront.

How weather-proof are the units?

It will depend on your site. Some office trailers can be placed flat on the ground with no additional securing needed. This works well for flat, level sites that are not prone to flooding or movement. But if your site is hilly, soft or prone to flooding, you may need additional stability features such as tie-downs, concrete foundation, or in-ground installation to prevent sliding or movement.

How do I choose a supplier?

Carefully. Read reviews, ratings and testimonials about the supplier. Look for hidden fees: delivery, add-ons, liability waivers, etc. Ask lots of questions.
