A single-wide portable office trailer is 8 to 12 feet wide and accommodates 1 to 6 people with one private office and an open area. A double-wide is two units connected together, typically 24 feet wide, accommodating 5 to 15 or more people with multiple private offices, an open conference area, and restroom facilities.

What is a portable construction office trailer?

A portable construction office trailer — also called a job site trailer, mobile office, or modular office — is a self-contained, transportable workspace unit designed for deployment on active construction sites, job sites, or any location requiring temporary office space. These units come fully wired for electricity, climate-controlled with HVAC, and ready for occupancy. They can be configured with restrooms, conference areas, internet connectivity, partition walls, and more. They adhere to national and state building, electrical, and plumbing codes.

What sizes of portable construction office trailers are available for rent?

Portable office trailers for rent are available in 8-foot, 10-foot, and 12-foot wide configurations, with lengths from 16 to 64 feet. Common rental sizes include 8×20 (200 sq. ft., 1–2 people), 8×28 (300 sq. ft., 2–3 people), 10×44 (400–550 sq. ft., 3–6 people), 12×56 (675 sq. ft., 5–6 people), and double-wide 24×56 (900–1,300 sq. ft., 7–10+ people). Triple-wide configurations exceeding 3,000 sq. ft. are available in some markets.

Should I rent or buy a portable construction office trailer?

Renting is typically the smarter financial choice for projects lasting under 3 years. The average monthly rental cost for a portable office is $100–$600 depending on size and features, and the average rental period runs 9–24 months. Buying makes more sense if you’ll use the trailer across multiple long-term projects or need a permanent portable office asset. Buying a portable office trailer typically runs $16,000–$30,000 depending on size and condition. If you’re unsure, request quotes for both options and compare.

What is a single-wide vs. double-wide portable office trailer?

A single-wide portable office trailer provides enough space for 1–6 people comfortably and typically includes one private office and an open area for additional workstations, storage, or cubicle-style layouts. Single-wide units range from 8-foot to 12-foot wide. A double-wide portable office trailer is two single-wide units connected together — typically 24 feet wide — creating one larger unit that can accommodate 5–15+ people. Double-wides often include multiple private offices, an open conference area, and restroom facilities, with total square footage up to 1,536 sq. ft. or more.

How quickly can a portable construction office trailer be delivered?

Pre-owned portable office trailers are in-stock and can typically be delivered within 3–7 business days of rental confirmation. Rush delivery is available in many markets. New units may require a slightly longer lead time depending on configuration. Delivery is handled directly to your construction site — you coordinate the date with the supplier and they handle setup. On-time delivery is guaranteed. Pick-up at end of term is always included.

Can a portable construction office trailer have a restroom?

Yes. Portable construction office trailers with restrooms — including standard, ADA-compliant, and shower facilities — are widely available for rent. Having an integrated restroom eliminates the need for separate porta-potty rentals, improving crew comfort and site professionalism. Restrooms are standard on most 12-foot wide and double-wide units and can be added to smaller units as an upgrade. Specify restroom requirements in your quote request.

Do I need a permit to place a portable office trailer on a construction site?

Permit requirements vary by city, county, and state. In most cases, a temporary portable office trailer placed on an active, permitted construction site falls under the main building permit and does not require a separate temporary structure permit. Some municipalities do require a standalone permit for any temporary structure. Our supplier partners know local requirements in the areas they serve and can provide guidance before delivery. Always confirm specifics with your local building or code enforcement office.

What features and add-ons are available on rented portable office trailers?

Most portable construction office trailer rentals include the basics: windows, vinyl floors, lighting, HVAC units, and deadbolt locks. Available upgrades and add-ons include: restrooms and showers, coffee and conference area setups, partition walls and private office configurations, office furniture (desks, chairs, filing cabinets), metal steps and OSHA-compliant ramps, security cameras and alarm systems, metal skirting to hide the trailer base, upgraded lock sets, internet and data connections, phone and fax lines, generators, awnings, and exterior lighting. Specify your requirements in the quote request and suppliers will confirm availability.
