Round Rock Porta Pros rents mobile office trailers for job sites, events and short-term operations that need a real workspace on site. A small mobile office trailer runs about 200 square feet, a larger unit doubles that, and most rentals get delivered within a week. If you need a place to run paperwork, hold meetings or store gear near the crew, this is the fastest way to get one on site.
A typical mobile office trailer interior has a desk area, shelving, an HVAC unit, and enough outlets to run a laptop, a printer and a space heater without tripping breakers. Some units on our lot also come as a mobile office enclosed trailer with a small bathroom built in, which matters if the site does not already have portable restroom rental nearby. If you need something closer to a standard job trailer with just desk space, we can point you toward the right size before you commit. For most Round Rock contractors running a crew of ten to twenty, a single trailer with a folding table and two workstations covers daily needs. If your project also needs electrical service on site, ask about a temporary power pole setup, since not every trailer pad has power already run to it. We also stock light tower rental units for sites running early mornings or after dark.
Mobile office trailer pricing depends heavily on size, amenities and rental length, and a trailer with a bathroom costs more than a bare desk unit. Below is a general reference range pulled from comparable trailer rentals we track, since mobile office units price closer to restroom trailers than to storage boxes.
| unit type | day | week |
|---|---|---|
| basic trailer | $175 - $800 | $1,397 - $1,650 |
| deluxe/equipped trailer | $800 - $2,500 | $1,397 (typical) |
Longer terms usually bring the daily rate down, so a monthly commitment tends to make more financial sense than renting week to week if your Round Rock project runs past thirty days. If you are weighing a full restroom trailer rental instead of an office unit, that page breaks out size options separately, including the 2 stall restroom trailer and 4 stall restroom trailer if you need both office space and restrooms on one site. For general rental cost comparisons across trailer types, see restroom trailer rental cost.
Round Rock Porta Pros focuses on rental units rather than a used mobile office trailer sale, so if you are trying to buy outright, we are not the right call. What we do offer is well-maintained rental stock, delivered and set up on your schedule, without the upfront cost of a purchase. Renting also skips the maintenance burden that comes with owning a mobile office trailer long-term. For contractors who need a workspace for a single project phase, a rental almost always beats buying, especially on a job that wraps in under six months. If storage is the real need rather than office space, take a look at storage container rental, including 20ft storage container and 40ft storage container options, which run cheaper per month than a trailer when you just need lockable space for materials.
Mobile office trailer weight varies by size and build, but delivery crews need real clearance to place these units safely, similar to the clearance needed for roll-off dumpster rental drops. A roll-off delivery needs about 60 feet of straight clearance behind the truck, and mobile office trailers need comparable room to maneuver and level. Before delivery day, walk the site and make sure there is a clear path in, since a blocked driveway or overhead line means the driver has to reroute or reschedule. Round Rock sites near new construction often have the most clearance trouble, so tell us up front if the pad is tight. We serve the full Round Rock area and nearby communities, including Brushy Creek 6.9 miles west, Hutto 8.1 miles east and Wells Branch 9.2 miles south, so delivery windows stay tight even outside the city core. If your project also needs a dumpster on the same pad, check dumpster sizes and dimensions before you finalize the site layout, since two large deliveries on one pad need real planning.
If your site also needs sanitation, a handwashing station rental or portable sink rental keeps crews compliant without adding plumbing. OSHA 1926.51(a)(1) requires an adequate supply of potable water at all places of employment, and if your crew is applying paints, coatings or similar contaminants, OSHA 1926.51(f)(1) requires washing facilities specifically for that exposure. For toilet counts alongside the office trailer, OSHA 1926.51(c)(1) sets the ratio at one facility per 20 workers or fewer, which is worth checking against your how many porta potties do I need numbers before the crew shows up. Round Rock job sites juggling an office trailer, restrooms and a dumpster in one delivery window should also glance at construction site services for the bigger picture.
Most rentals go out within about a week of booking, faster if you catch us during a slow stretch. Delivery timing depends on trailer size and site readiness. Call ahead if your Round Rock project has a hard start date so we can confirm the slot early.
Yes. Some units on our lot are built as a mobile office enclosed trailer with a small restroom, which saves you from renting a separate unit. If none fit your footprint, pairing a standard trailer with portable toilet rental works just as well.
A small mobile office trailer around 200 square feet usually covers a crew of five to ten comfortably, with room for a desk, files and a folding table. Bigger crews or trailers doubling as break rooms should size up.
Placement rules vary by lot and by whether the trailer sits in the right of way, so this needs confirming directly with the City of Round Rock before delivery. We can help time delivery around approval once you have that answer.
Yes, many sites run trailers on generator power when a hookup is not available yet. Ask us about pairing that with a temporary power pole if the job will need permanent service later in the project.
