Renting a mobile office trailer in San Rafael runs from a small single-desk unit up to a multi-room layout, with a comparable storage container running 100 to 250 dollars a month, and most contractors pair it with a standard porta potty or restroom trailer for the crew. San Rafael Porta Pros delivers, sets up and hooks up power, and can add a bathroom trailer for jobsite convenience, or a restroom trailer rental if you need more stalls.
There's no separate mobile office line in our measured pricing set, so the honest answer is that we quote it alongside the rest of your site package rather than as a stand-alone figure. What we can tell you: a storage container runs 100 to 250 dollars a month depending on size, and most jobsites that need an office also need a 20ft storage container or 40ft storage container for tools and materials nearby. Delivery for site equipment in this bracket typically falls in the 120 to 420 dollar range per month, based on distance and access. If you're budgeting for the full site, not just the trailer, check storage container rental cost and construction dumpster rental together, since crews usually order both at once, and a roll-off dumpster rental or 10 yard dumpster rental covers most jobsite debris needs alongside it. San Rafael sites with tight street parking or a permit-controlled curb often add a delivery fee, so ask for that number before you commit to a date. We'll give you one number that covers the trailer, the hookup and the drop, not five line items that don't add up until the invoice shows up; the same straight-quote approach applies to our porta potty rental cost and monthly porta potty rental pricing.
Layouts vary by job size, but the basics don't. A small mobile office trailer usually gives you a desk, a plan table, shelving, a window unit or wall AC, and enough headroom to stand a blueprint roll up in the corner. Larger units split into two rooms, one for the super and one for meetings or storage. If the trailer includes a bathroom, expect a small wet room built to the same clearance logic as any accessible unit on site: ADA Standards 404.2.3 calls for a 32 inch clear door opening, and where a route serves the trailer entrance, ADA Standards 403.5.1 sets a 36 inch minimum path width. Not every mobile office trailer with bathroom option meets full ADA clearance, so ask directly if that matters for your crew or your public-facing use. For a fully accessible restroom instead of a trailer bathroom add-on, our ADA accessible porta potty meets ADA Standards 213.2's cluster requirement on its own, and it is simpler to place and swap than modifying a trailer interior; see ADA restroom requirements for the full rundown.
Yes, but availability is tighter than a standard office box, and lead time matters more. Combination units cost more to move and service, so booking early gets you better placement options around San Rafael's tighter lots. If a bathroom-equipped unit isn't available on your timeline, most crews pair a bare office trailer with a nearby portable restroom rental, a porta john rental, or a deluxe flushable porta potty instead, which solves the same problem without waiting on a specialty trailer. Either way, OSHA 1926.51(c)(1) sets the toilet ratio for the crew working the site, not the office staff alone. That's one seat for 20 workers or fewer, so a five-person super crew in the trailer still needs to be counted against the full site headcount; our how many porta potties do I need guide walks through the math. If your project also runs paint, coating, or solvent work nearby, OSHA 1926.51(f)(1) requires washing facilities for that specific exposure, and 29 CFR 1910.141(d)(2) requires soap and towels or a dryer at any hand station you set up, not sanitizer alone. Add a handwashing station rental or portable sink rental near the trailer entrance to cover both rules cleanly, and check handwashing requirements if you're unsure which stations apply.
Placement in the public right of way needs confirming with the City of San Rafael directly, since permit rules and fees are not something we publish as fixed numbers here. What we do know from routing jobs around San Rafael: the city sits inland from the bay with narrow older streets downtown, and a trailer delivery needs real clearance to back in and level, similar to what we outline in our porta potty placement guide. A roll-off delivery, for comparison, needs about 60 feet of straight clearance behind the truck, and mobile office trailers need similar room even though the two units serve different purposes. If your lot backs onto a street shared with neighbors in San Anselmo, 4.3 miles west, or Larkspur, 5.1 miles southwest, tell us the cross street when you book so we can route the right truck. We check the drop zone before delivery day, not after, and we'll flag any spot that looks too tight for the trailer size you've chosen. For jobs further out toward Novato, 11.0 miles north, or Mill Valley, 8.7 miles south, delivery timing may shift, so confirm your window early. See our service areas page for the full list of towns we reach from San Rafael, including porta potty rental in Novato and porta potty rental in Mill Valley.
Sometimes, but condition matters more than age for a rental. A used mobile office trailer with a sound roof and working AC costs about the same to rent as a newer unit; what changes the price is size, hookup complexity, and whether it includes a bathroom. Ask about the specific unit's condition, not just its age, before comparing quotes.
Depends on crew size and function. A single desk and plan table fits in a small unit under 200 square feet; a super plus two staff usually needs a split two-room layout. If you're unsure, tell us headcount and we'll size it, the same way we size portable toilet rental counts against OSHA 1926.51(c), or how we size a construction site services package overall.
Most units run fine on a standard 100 to 200 amp temporary service depending on AC load and equipment inside. Confirm the trailer's exact draw before your electrician sets the panel, since undersized service is the most common startup delay we see on delivery day.
Weight varies by size and build, generally more than a standard storage container of the same footprint because of framing, insulation and interior fixtures. Tell us your access route and ground conditions and we'll confirm the unit fits your driveway or lot without a special permit for the tow.
Yes, short-term rentals happen, though most office trailer bookings run month to month rather than by the day like a porta potty rental per day order. If your need is truly short, ask us directly, since minimums and availability shift with what's already booked out of our San Rafael yard.
