Construction Office Trailers, On Site This Week
The site office is mobilization-critical path: permits get posted there, plans live there, and the owner walks into it on day one. We keep stock singles ready for mobilization-week orders, and your quote comes from the depot nearest the site so the delivery window is real, not optimistic.
Spec what the job actually needs: a super's office with a plan table runs fine in an 8×24; coordination-heavy jobs want a double-wide with a meeting room; secure document and device storage wants steel doors and window screens. Power typically comes off the temporary service; sanitation is usually portable units alongside rather than built-in plumbing.
Duration is your lever. A trailer for "the duration, call it 14 months" priced as a 12-month lease with extension beats month-to-month by a wide margin.
Built for the Way Jobsites Actually Run
We serve contractors, so the operational stuff is baked in. Delivery windows that respect concrete pours. Drivers who call before they roll. Steps with handrails on by default, because the inspector will ask. Postings wall inside the door, plan table where the light is, and a lock conversation before anyone has to raise it.
Mid-project changes are normal too. Crews grow, trailers swap, a second unit arrives for the finish push. Because your site already sits in our delivery network, adding or swapping a unit is a phone call, not a procurement cycle. Tell us the job and we will keep the office part boring, which is exactly how site offices should be.

Construction Trailer FAQs
What size trailer does a typical jobsite need?
A superintendent office plus plan table fits in an 8×20 or 8×24. Add a project engineer and an owner meeting space and you are into 10×40 or 12×60. Multi-trade coordination jobs and CM offices usually run a 24×60 double-wide. About 100 sq ft per regular occupant is the working rule.
How fast can a construction trailer be on site?
In-stock units deliver in 3 to 10 business days in most metros. Mobilization-week orders are routine for our depots, but access matters: the truck needs a firm path, roughly 12 ft wide, and clearance to set and level the unit.
Does OSHA require anything specific for site offices?
OSHA governs the site as a workplace rather than dictating trailer specs: safe egress, lighting, heating, sanitation provision, and electrical safety all apply. Steps with handrails and GFCI-protected hookups are the practical must-haves. Our site office requirements guide covers the details.
Rent or buy for construction use?
Per-project GCs rent: the trailer demobilizes with the job and maintenance stays with us. Contractors with a steady project pipeline increasingly buy one or two used units and rent only the overflow, which the quote form can price both ways in one pass.
