8×36 Office Trailer
The 8×36 is the largest office trailer that still travels at legal width — 256 square feet, two to four people, and the last size in the range that moves with no oversize permit, no pilot car and no route survey. Rentals run $275 to $475 per month; used units sell from $7,000.
It is also commonly sold as an office storage trailer, with part of the box partitioned for materials rather than desks.

8×36 Office Trailer Specifications

|---|---|
| Box dimensions | 8 ft × 32 ft |
| Floor area | 256 sq ft |
| Exterior width | 8 ft — under legal load width, no permit |
| Working occupancy | 2 to 4 people |
| Typical layout | Open room, or one office plus storage |
| Restroom | Occasional — usually a half bath |
| Estimated dry weight | 7,800 – 8,600 lbs |

The box is 32 feet, not 36. From about this size up, towable office trailers are named by overall towing length including a roughly four-foot hitch. Eight by thirty-two is 256 square feet, not the 288 the model name implies. Suppliers quoting on the nominal number look cheaper per square foot than ones quoting honestly.
How Much Does An 8×36 Office Trailer Weigh?
Expect 7,800 to 8,600 pounds empty. No manufacturer publishes a figure for this exact size, so that range is derived from the two published weights either side of it.
| Size | Published Dry Weight | Source |
|---|---|---|
| 8×20 | 4,982 lbs | Mobile Modular |
| 8×32 | 7,500 lbs | Williams Scotsman |
| 8×36 | 7,800 – 8,600 lbs (estimated) | Interpolated |
| 8×40 | 8,554 lbs | Mobile Modular |
Treat that as a planning figure and get the actual number from the unit’s data plate or the supplier’s spec sheet before booking transport. Weight varies by several hundred pounds between manufacturers and moves further with options — a plumbed restroom, a second HVAC unit or heavier interior finishes all add.
Why it matters: at this weight the trailer tows behind a standard one-ton truck with an appropriate hitch rating rather than needing a lowboy, which is part of why the 8-foot sizes are cheaper to move than anything wider. It also determines the ground bearing your pad needs, and whether a forklift on site can reposition it.
The Last Size That Moves Without A Permit
This is the 8×36’s real argument, and it is worth more than the extra square footage over an 8×20.
Legal load width in most states is 8 feet 6 inches. At 8 feet wide, the 8×36 travels as a standard load — no oversize permit, no pilot car, no route survey, no restricted travel hours. Step up to the 10×40 and all four of those appear on every single move.
| 8×36 | 10×40 | |
|---|---|---|
| Floor area | 256 sq ft | 360 sq ft |
| Exterior width | 8 ft | 10 ft |
| Oversize permit | No | Yes, every move |
| Route survey | No | Usually |
| Typical layout | Open, or office plus storage | 1 private office plus open area |
If the trailer will be relocated repeatedly — following a crew between jobs, or moving within a large site — that permit difference compounds on every move. On a single placement for the length of one project, it is a one-time saving and the extra 104 square feet of the 10×40 may well be worth more.
Office, Storage, Or Both
The 8×36 is the size most often sold as a combination office and storage trailer, and that is worth understanding before you compare quotes, because the same nominal unit comes three ways:
- Full office. All 256 square feet finished, insulated and conditioned. Two to four desks, or one small private office and an open area.
- Office plus storage. A partition wall with roughly two thirds finished as office and the remainder left as unconditioned storage with its own door. Common on job sites that need a secure tool and materials space alongside the office.
- Storage only. Unfinished, uninsulated, no HVAC or electrical beyond basic lighting. Substantially cheaper and not comparable to the figures on this page.
The prices above are for a finished office unit. A quote that comes back well below the range is usually a storage-configured trailer, so confirm which one is being priced.
What 256 Square Feet Actually Holds
Suppliers list two to four occupants. Against a normal planning figure of 50 to 75 square feet for an open-plan workstation and 100 to 150 for a private office:
| People | Square Feet Each | In Practice |
|---|---|---|
| 2 | 128 | Comfortable, with room for a plan table and files |
| 3 | 85 | Works well. The realistic target for a full-office configuration |
| 4 | 64 | Tight, and only if the crew is mostly on site rather than at desks |
Take a third off those numbers if the unit is an office-plus-storage configuration, because the partition takes the space with it. An office-plus-storage 8×36 is realistically a two-person office.
Why It Costs More Per Square Foot Than A 12×60
An 8×36 runs $20,000 to $32,000 new for 256 square feet. A 12×60 runs $25,000 to $55,000 for 672. That is roughly $100 per square foot against $60.
The reason is that a large share of what goes into an office trailer does not scale with floor area. Axles, running gear and the hitch, the electrical panel, the HVAC unit, the entry door and steps, the roof structure — a small trailer needs nearly all of the same components as a large one and spreads them over a third of the floor.
The practical read: buy the smallest unit that genuinely fits your crew, not the cheapest per square foot. Paying for floor you will not use is the more common mistake, but so is buying an 8×36 for four people because the price per foot looked bad on a 10×40.
Delivery And Site Requirements
- No permit needed at 8 feet wide, which keeps delivery cost and lead time down on every move.
- A firm, level pad the full 36 feet of towing length. Blocking absorbs inches, not slope, and a 32-foot box shows a grade a 20-foot one hides.
- Six tie-downs is typical at this size. Coastal and high-wind counties may require more.
- Typically a 100-amp service. Confirm the panel spec against what the site can supply.
- Steps and a landing, plus a ramp if anyone other than staff will enter.
8×36 Office Trailer FAQ
How much does an 8×36 office trailer weigh?
Expect roughly 7,800 to 8,600 pounds empty. No manufacturer publishes a figure for this exact size, so that estimate is bracketed by published weights either side of it — Williams Scotsman lists an 8×32 at 7,500 pounds and Mobile Modular an 8×40 at 8,554. Get the exact figure from the unit’s data plate before booking transport, because weight varies by manufacturer and by options like a plumbed restroom or a second HVAC unit.
How big is an 8×36 office trailer?
256 square feet. The box measures 8 feet by 32 feet, not 36, because towable office trailers at this size are named by overall towing length including a roughly four-foot hitch. That is about 11 percent less floor than the model name suggests.
Does an 8×36 office trailer need an oversize permit?
No. At 8 feet wide it sits under the 8-foot-6-inch legal load width used in most states, so it travels as a standard load with no permit, no pilot car and no route survey. It is the largest office trailer size where that is true — a 10-foot-wide unit needs all of them on every move.
How many people fit in an 8×36 trailer?
Three is the realistic target for a full-office configuration, at about 85 square feet each. Two is comfortable with room for a plan table. Four is tight and only works for a crew that is mostly out on site. If the unit is an office-plus-storage configuration, take a third off — it is realistically a two-person office.
What is an office storage trailer?
A combination unit with a partition wall, typically around two thirds finished as conditioned office space and the remainder left as unconditioned secure storage with its own door. The 8×36 is the size most commonly sold this way. A quote that comes in well below the usual range for this size is often a storage-only trailer rather than a finished office, so confirm which is being priced.
Why does an 8×36 cost more per square foot than a bigger trailer?
Because axles, running gear, the electrical panel, the HVAC unit, the entry door and the roof structure barely change between a small trailer and a large one, and a smaller unit spreads that fixed content over less floor. An 8×36 works out near $100 per square foot new against roughly $60 for a 12×60. Size the unit to the crew rather than to the price per foot.
Is it cheaper to rent or buy an 8×36 office trailer?
At a mid-range $375 per month against a mid-range $14,500 used purchase, break-even lands somewhere near the 39th month, before counting resale value. That is longer than the smaller 8×20’s roughly 21 months, so on projects of two to three years renting usually wins at this size.
