How much does a mobile office trailer cost to rent?
Monthly rent depends mostly on size. These are typical 2026 national ranges before delivery, setup, and tax:
| Mobile office trailer size | Floor area | Typical monthly rent |
|---|---|---|
| 8’x20′ small office | 160 sq ft | $200–$400 |
| 10’x40′ mid-size office | 400 sq ft | $300–$500 |
| 12’x60′ large single-wide | 720 sq ft | $500–$700 |
| 24’x60′ double-wide | 1,440 sq ft | $800–$1,800 |
Delivery and setup usually add $1,000 to $4,000, and most suppliers charge again to pick the unit up at the end of the term. Longer terms (6–12 months or more) bring the monthly rate down. Single-wide ranges are from 360Connect’s mobile office renter’s guide; double-wide and delivery ranges are from RentalHawk’s 2026 mobile office cost guide. Your quotes will vary by region, term, and options.
What drives the price up or down
- Size and layout: private offices, a restroom, or a conference room add cost.
- Term length: month-to-month costs more per month than a 12-month term.
- Delivery distance: transport is usually billed by the mile from the supplier’s yard.
- Setup: blocking and leveling, tie-downs, steps, and an ADA ramp if your site needs one.
- Extras: furniture, security packages, and damage waivers.

Mobile office trailer FAQ
Do I need a permit for a mobile office trailer?
Often, yes. A construction trailer on an active, permitted job site is usually covered by that project, while a mobile office used as a standalone business office typically needs a local building or zoning permit. Rules vary by city and county, so check with your local building department before delivery. Read more about permits for modular buildings.
Are steps and a ramp included?
Usually not. Most suppliers rent steps as an add-on, and if the public or employees with disabilities will use the office, an ADA-compliant ramp may be required. See our guide to ramps and steel stairs.
How fast can a mobile office trailer be delivered?
When a unit is in stock near you, delivery can happen within days to a few weeks. Permits, site prep, and custom layouts add time. Learn how fast you can get a modular office.
Can I get a mobile office trailer with a restroom?
Yes. A 12’x60′ single-wide commonly fits a restroom, and larger double-wides can include several. A restroom needs water and sewer connections at your site, which adds setup cost.
