What size mobile office trailer do I need?
Most San Leandro jobsites land on one of three sizes: a small mobile office trailer for one or two desks, a mid-size unit with a meeting area, or a larger trailer with a mobile office trailer with bathroom built in. If you're staffing a crew of 20 or fewer, that same headcount is the line OSHA draws for toilet counts under OSHA 1926.51(c)(1), and it's a useful gut check for how many people the trailer itself needs to seat. Interior layout matters more than square footage. A mobile office trailer interior with a separate plan room, a small kitchenette and a bathroom stall works better for a general contractor running subs through the trailer daily than one open room. If you're not sure what fits your crew, request a quote and we'll size it against your headcount and your site plan, the same way we'd size a restroom trailer rental against expected users.
Can I rent a mobile office trailer near me in San Leandro?
Yes. San Leandro Porta Pros delivers mobile office trailers within San Leandro and to nearby communities including Ashland, 3.8 miles east, and San Lorenzo, 4.1 miles southeast. We also reach Union City, 13.3 miles southeast, and San Ramon, 22.8 miles east, for larger contractors running multiple sites. A roll-off dumpster rental delivery on the same site needs about 60 feet of straight clearance behind the truck, and mobile office trailers need similar clear approach, so tell us about gates, overhead lines and grade before delivery day. If your site sits along a public curb or right of way, placement there needs confirming with the City of San Leandro; we haven't verified a specific ordinance for trailer placement and won't guess at one.
Do mobile office trailers come with a bathroom and power hookup?
Some do, some don't, and it depends on the unit. A mobile office trailer with bathroom typically needs its own water supply and a holding tank serviced on a schedule, similar to how a standard portable toilet runs on a 60 to 70 gallon holding tank. For a bathroom-equipped trailer, we can arrange service on the same rotation as your other units, and pair it with a handwashing station rental if you need supplemental hand washing near a work area rather than inside the trailer. Power is usually customer-supplied or run through a temporary power pole; OSHA's general requirement for potable water at places of employment, 1926.51(a)(1), is worth keeping in mind if the trailer's water isn't hooked to a permanent line yet. Ask us about GFCI protection per OSHA 1926.404(b)(1)(ii) if you're running temporary power to the trailer from a generator or panel.
Is a used mobile office trailer rental cheaper than a new one?
Rental pricing depends more on trailer size and rental duration than on trailer age, since San Leandro Porta Pros prices the rental term, not the unit's manufacture date. What matters most for your budget is how long you need it and what's inside. A bare single-room trailer for a short punch-list job costs less than a multi-room unit with a bathroom rented for months. If you're comparing a mobile office trailer sale against renting, renting avoids the maintenance and storage problem once the job wraps, and it scales up or down as your crew size changes. For side-by-side cost planning across restroom equipment on the same site, our restroom trailer rental cost guide breaks down comparable duration pricing that applies the same logic to office trailers.
| unit | day | week | month |
|---|---|---|---|
| standard portable toilet | 100-350 | 130-500 | 125-325 |
| deluxe flushable unit | 85-1200 | 150-290 | -- |
| storage container | -- | -- | 100-250 |
| dumpster | 51-112 | 426-778 | 91-500 |
These figures cover the restroom, storage and dumpster equipment San Leandro Porta Pros rents alongside mobile office trailers; ask us directly for a trailer quote sized to your job, since trailer pricing varies more by configuration than these standardized units do. Weight is another common question: mobile office trailer weight varies with length and whether it includes a bathroom module, water tank and furnishings, so we confirm axle and towing specs against your site access before delivery, especially on soft ground or tight urban lots common around San Leandro.
Need the rest of the site secured while the trailer sits on-site? Pair it with temporary fence rental or a chain link temporary fence to keep the office area separated from active construction, and add a light tower rental if crews are on-site before sunrise. For active construction sites juggling several types of equipment at once, our construction site services page walks through how trailers, containers and sanitation typically get scheduled together.
Frequently asked questions
How long can I rent a mobile office trailer for?
Rental terms run from short-term jobs to multi-month contracts. San Leandro Porta Pros structures the agreement around your project timeline, not a fixed minimum, so a two-week punch-list job and a six-month build both work.
What's inside a typical mobile office trailer interior?
Layouts vary, but most include a desk area, storage cabinets and sometimes a small meeting table. Bathroom-equipped units add a stall and sink. Tell us your headcount and daily use pattern and we'll match the interior to it.
Do I need a permit to place a mobile office trailer in San Leandro?
Possibly, depending on where it sits. Placement in the public right of way needs confirming with the City of San Leandro directly; we haven't verified a specific rule and won't state one without checking first.
Can a mobile office trailer be delivered with a storage container on the same trip?
Often, yes, if site access allows both. Many contractors book a storage container rental alongside the office trailer so tools, materials and desk space arrive together and get set on the same lot.
What's the difference between a mobile office trailer and a restroom trailer?
An office trailer is built for desks and paperwork; a restroom trailer rental is built for stalls and plumbing. Some office trailers include a small bathroom, but dedicated restroom trailers handle higher user counts better.
