The value of your used modular office trailer depends on several factors such as the age, floor plan, and features, condition of the structure, condition of the roof and floor, condition of the heating and air conditioning system(s), and the amount of time, materials and effort it will take to remove and relocate it from its current location. To sell used modular office trailer, you must know its worth.

Note: If you are ready to sell your used modular office trailer you can start by sending us some photographs and details for a quick evaluation and our professional recommendations.
Age / Date of Manufacture
This factor is the most obvious. The newer the modular office trailer the better its resale value will be in most markets. Older modular buildings, even if in good condition, will have depreciated to a much lower value. Check your title or the identification tags typically found on one of the ends of the structure or its chassis for the manufacturer’s insignia and date of manufacture.
Floor Plan & Dimensions
One of the first questions you should consider before you try to sell your used modular office trailer is whether or not it is a commonly used size and an “in demand” style of a temporary building.
For example, a standard modular office trailer with interior offices, male and female/unisex bathrooms, heating and air conditioning, standard exterior doors and windows is very marketable. In comparison, a unique floor plan that has special doors and windows, odd-shaped offices, shower and locker room areas, large kitchens or anything that was “customized” for a specific user’s needs is more difficult to re-sell. Finally, dimensions matter and if you have a standard-sized modular building it will be much easier to remove, transport, and install at the buyer’s location than if the length or width is odd. Typical modular office building sizes in the United States consist of sections that are 10′ and 12′ in width and range from, 40′ to 60′ in length.
Condition of the Structure, Roof & Floor
The condition of the modular office’s major structural components is important for valuation and occupant’s safety and security.
In most cases, major problems with the roofing or flooring of the modular are easily identified. Here are some of the most common signs and symptoms that will negatively impact the value of your used modular office:
- Roof leaks/water inside the usable space
- Visible daylight through the roof
- Delaminated floor and wall finishes
- Mold / Mildew on ceiling tiles, wall finishes
- Drooping of the roof or floor
* Note: If you have made any modifications to the actual steel frame or roof structure of the modular office trailer you will need to show that a structural engineered approved the modifications. Otherwise, you run a huge safety risk that the buyer must be made aware of in advance.

Heat, Air Conditioning, Electrical & Plumbing
Depending upon your location and climate patterns the heating and air conditioning system(s) installed on your modular office trailer can either be in good working condition or completely overworked and in need of maintenance, repair, or replacement. This can affect the value and the cost the buyer will need to invest to bring the modular up to comfortable working conditions.
If you are positive that your heating and cooling systems are in great working condition there is no need to look into this item. If not, it makes the best sense to call a local HVAC company and have them assess the condition and either complete the needed work or disclose what’s needed with a formal price quote.

* Note: Most modular offices in the U.S. will have a Bard or Marvair wall-mounted HVAC system. Wall mounts are fairly easy to maintain, repair, or replace.
Removal & Relocation from Your Site
The final piece of the modular office resale puzzle is the condition of the site where the structure is currently located. The costs for removal and relocation can range based on the following questions:
- Does the modular office trailer have its original wheels, axles, and hitches? Check underneath the structure.
- Are there site obstacles such as other modular trailers, traditional buildings, or landscaping that will need to be moved or removed to make the removal of the modular trailer easier?
- Does the modular office trailer have wheelchair ramping, custom decking, awnings, and steps that will need to be removed?
- If there are difficult utility connections who will handle these and pay for the permits and work required for safe disconnect
- What will it cost to return the site of the modular office trailer back to its original condition?
Finally, if you are ready to sell any type of used modular office trailer, portable classroom, or mobile office trailer it makes good sense to speak with one of iModular’s experts. Be sure to take quality photos of the modular office’s interior, exterior, and any other important features and send them to us using our modular building resale tool. If you have the original floor plan and title you should send that as well.
