A popular 10×40 runs $25,000–$40,000 new or $12,000–$25,000 used, with age and condition setting where a used unit falls.

Office Trailers for Sale: New and Used Buyer's Guide
Office trailers for sale range from a small used 8×20 at about $5,000 to a new 24×60 double-wide at $75,000 or more. That is a wide spread for what looks like the same box. Size, age and condition explain most of it, and the costs of delivery, setup and hookups decide what you really pay.
This page is for contractors, business owners and facility managers who are shopping office trailers for sale because they want to own a unit rather than rent one. It covers purchase prices for new and used trailers, the kinds of sellers you will meet, how to judge a used unit, what to ask before you pay, and what ownership adds once the trailer is yours. It also explains how to pay for one and how to sell it again when the job ends.
What Office Trailers Cost to Buy, New and Used
Size sets the price first. Condition sets it second. The table shows the planning ranges this site uses for office trailers for sale in the four sizes buyers ask about most, with the capacity each one usually handles.
| Size | Square Feet | Typical Capacity | New Price | Used Price |
|---|---|---|---|---|
| 8×20 | 160 sq ft | 1–2 people | $15,000 – $22,000 | $5,000 – $14,000 |
| 10×40 | 400 sq ft | 3–5 people | $25,000 – $40,000 | $12,000 – $25,000 |
| 12×60 | 720 sq ft | 5–8 people | $35,000 – $55,000 | $18,000 – $38,000 |
| 24×60 Double-Wide | 1,440 sq ft | 10–15 people | $55,000 – $75,000+ | $25,000 – $50,000 |
Other sizes, such as an 8×36 or a 10×50, generally price between their neighbours in the table. A used unit lands low or high in its range mostly on age and condition. Restrooms, extra private offices, upgraded finishes and a newer HVAC system push any trailer toward the top.
Listed prices on office trailers for sale usually cover the unit alone. Delivery, blocking, steps and power come on top, and they are covered further down. For floor plans and exact dimensions of every size, see our office trailer sizes guide.
💡 Compare Quotes on the Same Terms
When you compare office trailers for sale, ask every seller to price the same size, the same condition and the same delivery scope. A low unit price with delivery, steps and setup left out can cost more than a higher quote that includes them.
Who Sells Office Trailers
You will find office trailers for sale through a handful of seller types. Each one trades price against selection, condition and protection in a different way. Knowing which kind you are talking to tells you what questions to ask.
Rental Fleet Sales
Companies that rent office trailers put older fleet units up as used office trailers for sale. These units have usually been rented many times, so ask for any service records the seller has.
New and Used Dealers
Dealers stock new units and trade-ins, and many can bundle delivery, steps and setup into one quote. Pricing is often open to discussion.
Manufacturers
Buying new from the factory gives you the most say over layout and finishes. Expect to wait longer for a unit built to your order than for one in stock.
Private Sellers and Listings
Contractors and businesses list used mobile office trailers for sale online when a project ends. Prices can be lower, but the sale is usually as-is.
Auctions and Surplus Sales
Equipment auctions and government surplus sales sometimes include office trailers. You rarely get a full inspection, and there is no warranty.
Whichever seller you use, look at the unit in person or send someone who knows trailers. Photos hide soft floors and roof leaks. A seller who will not allow an inspection is telling you something.

The choice between new and used office trailers for sale comes down to who will use the space, how long you will keep it, and how much wear you can live with. A crew office behind a fence has different needs than a sales office customers walk into.
Buy New When...
- Customers or the public will visit the office
- You need a layout or finish no used unit offers
- You plan to keep the trailer across many projects
- You want a manufacturer's warranty
- Your site has code requirements a used unit may not meet
Buy Used When...
- The trailer is for a crew or back-office use
- Budget matters more than appearance
- A standard layout does the job
- You need a unit sooner than a factory order allows
- You may sell it again after one or two projects
A used office trailer costs well under a new one of the same size, as the price table shows. That gap is the whole reason to buy used. It only holds if the unit does not need a new roof, floor or HVAC system in the first year.
If you are weighing a trailer against a skid-mounted portable office or a permanent modular building, our portable office buildings guide compares the three.
How to Judge a Used Office Trailer
Used office trailers for sale vary more in condition than in price. Two units of the same size and age can be very different buys. Walk the whole unit, inside, outside and underneath, before you talk numbers.
| What to Check | What to Look For | Why It Matters |
|---|---|---|
| Age and records | Build date on the label or data plate, service history, number of moves | Tells you how much life the systems have used |
| Frame and hitch | Rust, cracks, bent beams, poor weld repairs, a damaged tongue | The frame carries the building and takes the stress of every move |
| Roof | Ponding, tears, open seams, stains on the walls below the roofline | Leaks cause hidden damage to ceilings, walls and floors |
| Floor | Soft spots, sagging, stains, especially near doors and exterior walls | A soft floor usually means water has reached the subfloor |
| HVAC | Run heating and cooling; listen for noise and feel the airflow | One of the largest systems to replace on a used unit |
| Windows and doors | Failed seals, cracked glass, doors that stick, broken locks | Affects security, weather tightness and comfort |
| Electrical | Every outlet and light, a labelled panel, no amateur wiring | Poor wiring is a fire risk and may fail inspection |
| Label or data plate | The state modular or industrialized building label, or the maker's data plate | Your building department may ask for it before approving the unit |
Many states run a modular or industrialized building program with plan review, in-factory inspection and a state label. Rules vary by state. The HUD code covers manufactured homes only, so it does not apply to a commercial office unit.
A missing label is not always fatal, but it can make permitting harder. Ask your local building department what it will need before you buy a unit without one. An inspector familiar with modular or manufactured buildings is worth hiring for anything larger than a small single-wide.
⚠️ Walk Away When You See These
- A cracked or badly bent main frame beam. The repair can cost more than the trailer is worth.
- Active mold or a strong musty smell. Both point to a moisture problem that goes deeper than the surface.
- No title, bill of sale or proof of ownership. You could inherit a lien or a dispute.
- A seller who refuses an inspection. There is usually a reason.
- Fresh paint over the whole interior. Ask what it covered.
Questions to Ask Before You Buy
Ask these whenever you look at office trailers for sale, new or used. Good sellers answer without hesitation. Get the answers in writing, especially on a used unit. They also make quotes from different sellers easier to compare.
📋 Questions for Any Seller
- What year was it built, and is the state label or data plate still attached?
- How was it used, and how many times has it been moved?
- What repairs have been made to the roof, floor, HVAC and electrical?
- Are the axles, tires and hitch still with the unit?
- Is there a title or bill of sale, and is it free of liens?
- Does the price include delivery, blocking, leveling and steps?
- Is there any warranty, and what does it cover?
- Can I bring my own inspector before I pay a deposit?
- What is the refund policy if the unit fails inspection on arrival?
Ask new-unit sellers what the base price includes. Furniture, skirting, a ramp and a restroom are often extras. For construction trailers for sale meant as jobsite offices, also ask whether the unit suits the power and internet setup your site will have.

When you rent, the supplier handles most of the logistics. When you buy, they are yours. Budget for these before you agree a price on any of the office trailers for sale you are considering.
| Item | Typical Range | What Drives It |
|---|---|---|
| Delivery and setup | $1,000 – $5,000 | Distance from the seller, plus blocking, leveling and tie-downs on arrival |
| Steps | $200 – $600 | Nearly always needed, since trailers sit above grade |
| ADA ramp | $300 – $800 | Needed where the public or employees require an accessible entrance |
| Electrical hookup | $150 – $1,000 | Distance to the panel or temporary power pole |
| Permits, insurance, storage | Varies | Set by your jurisdiction, your insurer and where the unit waits between jobs |
📊 Worked Example: A Used 10×40 Ready to Use
Used 10×40 trailer: $12,000 – $25,000
Delivery and setup: $1,000 – $5,000
Steps: $200 – $600
Electrical hookup: $150 – $1,000
Total before permits and insurance: $13,350 – $31,600
A double-wide costs more to deliver and set than a single-wide. It arrives as two halves that are joined, sealed and leveled on site. Wide units also need more planning on the road. Federal rules say that on the National Network, no state may impose a width limitation of more or less than 102 inches, so check the transport width with your seller.
Your site needs a level, well-drained pad and a clear route for the truck before delivery day. Blocking and leveling keep the doors and windows working. Skirting keeps animals and wind out from underneath.
Permits depend on your city or county, how long the unit stays and how it is used. The International Code Council's model building code includes language specifically addressing relocatable buildings, and local amendments vary. Your building department has the final word.
Accessibility may apply too. The ADA's Title III page lists office buildings among commercial facilities, and when businesses build or alter facilities, they must follow the ADA Standards for Accessible Design. Ask your building department how that applies to your placement.
Insurance is the last piece. Ask your insurer to cover the unit on site and while it is being moved. The day the project ends, you will also need a place to store it or a buyer lined up.
Paying for It: Cash, Loans and Tax Questions
You can pay cash or finance office trailers for sale through a dealer, a bank or an equipment lender. Cash is simplest for a small used unit. Some dealers and manufacturers offer their own financing. Compare the full cost of the loan, not just the monthly payment.
For-profit small businesses can also look at SBA-guaranteed loans. SBA 7(a) loans are delivered by SBA lenders, and the SBA's 7(a) page lists uses including the purchase and installation of machinery and equipment. Businesses must meet SBA size standards and be able to repay.
Taxes are a question for your tax adviser. IRS Publication 946 explains how businesses recover the cost of property through depreciation and the Section 179 deduction. Whether a trailer is treated as equipment or as a building is your adviser's call.
Rent or Buy?
Buying pays off only when you use the unit long enough. Divide the purchase price by the monthly rent for the same size to get a rough break-even point. Our office trailer rental guide works through that math. On its numbers for a 12×60, owning starts to cost less than renting after roughly 3½ years for a used unit and 5 years or more for a new one, before insurance, maintenance and storage.
Selling Your Office Trailer When the Job Ends
Owning means planning the exit on day one. A trailer that sits unused in a yard still costs you insurance and storage. Selling it, moving it to the next project, or renting it out are the usual choices.
When the job ends, your unit joins every other listing of used office trailers for sale. The things that make a used unit easy to buy also make yours easy to sell. Keep the label or data plate attached. Keep the title or bill of sale and every repair receipt. Replace HVAC filters, fix roof leaks quickly and deal with soft floors before they spread.
Common sizes such as the 10×40 and 12×60 suit more buyers than an unusual layout. Clean photos of the interior, a list of recent repairs and a clear statement of what the price includes all help. So does being honest about condition.
Moving a trailer to a new site means another round of delivery, setup and hookups. Price that in before deciding whether to keep it for the next job or sell it where it stands.

Where can I find used office trailers for sale?
Used office trailers for sale come from rental fleets selling older units, new and used dealers, private sellers through online listings, and equipment auctions or surplus sales. Inspect any unit in person, whoever is selling it.
What should I check before buying a used office trailer?
Check the frame and hitch for rust and cracks, the roof for leaks, the floor for soft spots, and run the HVAC. Test the windows, doors and electrical, and confirm the state label or data plate is still attached.
Is it cheaper to buy or rent an office trailer?
Divide the purchase price by the monthly rent for the same size to find a rough break-even point. For a 12×60 it lands at roughly 3½ years used and 5 years or more new, before insurance, maintenance and storage, so shorter projects usually favor renting.

Do I need a permit for an office trailer I own?
Usually, yes. Permit rules depend on your city or county, how long the trailer stays and how it is used. Your building department may also ask about the state label. Check with your local building department before you buy or schedule delivery.
Can I finance an office trailer purchase?
Yes. Dealers, banks and equipment lenders finance office trailers for sale, and SBA 7(a) loans can be used to buy equipment if your business qualifies. Ask a tax adviser about depreciation and Section 179 before you buy.
Can I resell an office trailer later?
Yes. Common sizes such as the 10×40 and 12×60 suit the most buyers. Keep the label or data plate, the title or bill of sale and repair records, and fix leaks and soft floors quickly to protect the price.
