How much does a mobile office trailer cost to rent in Beaverton?
A trailer runs from a day rate up into the thousands depending on size and how long you need it, and the spread is wide because a small mobile office trailer and a full construction unit with a bathroom are priced nothing alike. Below are the bands we see across measured rentals. If you are also weighing a restroom trailer rental for the crew, check restroom trailer rental cost separately, since that is a different unit than an office trailer.
| duration | low | typical | high |
|---|---|---|---|
| day | $175 | $800 | $2,500 |
| week | $150 | $1,397 | $1,650 |
| event | $2,499 | $3,500 | $3,899 |
| weekend | $900 | $2,000 | $3,000 |
A delivery fee applies on top of the trailer rate, and that alone can run from $100 to $500 depending on distance and site access. If you are staging a trailer for a wedding tent or a fairground booth instead of a construction office, price it against event restroom rental and festival restroom rental, which use different equipment entirely.
What size mobile office trailer do I need?
Most single-supervisor setups run a small mobile office trailer, while multi-desk crews or a unit with a bathroom need something bigger, and Beaverton Porta Pros can walk the site with you before quoting a size. A used mobile office trailer for sale is a different transaction than a rental, and we do not sell; everything here is rented and delivered to your Beaverton address or job lot. Delivery needs clearance similar to what a roll-off dumpster rental requires, since a straight approach of about 60 feet behind the truck makes placement faster and avoids a second trip. If your lot is tight, tell us before delivery day; that single call saves a redelivery fee.
Interior layout matters more than square footage. A mobile office trailer interior with a desk, a small conference space, and a separate bathroom stall works for site supervisors who need privacy for calls and plan review. If you only need sanitation and not office space, a standalone portable restroom rental or a deluxe flushable porta potty is the cheaper path, and pairing that with a bare office trailer often beats renting a combo unit.
Does a mobile office trailer need power and does it come with a bathroom?
Not automatically. A mobile office trailer with bathroom needs both a water connection or holding tank and an electrical hookup, and neither comes standard on a bare enclosed trailer. Beaverton Porta Pros can add a handwashing station rental or portable sink rental next to the office if the bathroom option is not in your build, and 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device at any washing facility, not hand sanitizer alone. For sites already running a generator or temporary service, a temporary power pole can feed the trailer directly. If your crew count is high enough that you are tracking OSHA 1926.51(c) toilet ratios for the whole site, a mobile office trailer bathroom does not replace that count. It is a convenience fixture, not your crew's compliance solution, so keep a standard porta potty rental or ADA accessible porta potty on site as well.
What does a mobile office trailer weigh and what do I need to know before delivery?
Weight varies by size and build, and it is one of the first things we confirm before scheduling delivery, since it determines the truck and the site access we plan for. A mobile office trailer enclosed unit sits heavier than an open flatbed style, and larger multi-desk units weigh more than a compact single-office box. Beaverton sites near Cedar Hills, about 2.3 miles north, and West Slope, about 3.0 miles northeast, are common delivery points, and access there tends to be tighter than open construction lots further out. Marlene Village, 3.6 miles north, and Tigard, 6.1 miles southeast, are also inside our regular run. If you are comparing an office trailer against buying, note that a used mobile office trailer for sale carries none of the delivery, service or removal handled through a rental, and most contractors on a defined project timeline still rent. For longer stays, a monthly porta potty rental alongside the trailer often costs less than repeated short-term swaps, and our porta potty rental cost page breaks down that comparison in detail.
How long can I rent a mobile office trailer for?
Day, week, weekend and event durations are all available, and most construction jobs book by the week or month rather than by the day. Longer terms bring the effective daily rate down. Tell us your project length up front so we can quote the right duration instead of stacking short-term rates.
Can I get a mobile office trailer near me delivered fast?
Same-day and next-day delivery is often possible depending on the trailer size and your location within the Beaverton service area. Call ahead if your start date is fixed. Our emergency porta potty rental line handles urgent sanitation, and trailer delivery follows a similar rush process when a slot is open.
Is a mobile office trailer the same as a construction dumpster or storage container?
No. An office trailer is workspace, not disposal or storage. For debris, see construction dumpster rental or check dumpster sizes and dimensions; for equipment and materials, look at 20ft storage container or 40ft storage container instead.
What comes standard inside a mobile office trailer?
A desk area and basic lighting are standard on most units; a bathroom stall, sink and heating or cooling are options you specify when booking. Ask about the mobile office trailer interior layout before delivery so it matches your crew size and daily use.
Do I need a permit to place a mobile office trailer in Beaverton?
Placement in the right of way or on certain lots needs confirming with the city before delivery; we have not verified a specific rule for office trailers. Check with Beaverton's permitting office directly, and see our porta potty permit requirements page for how we handle that question on related equipment.
