Workspace That Arrives Ready to Use
Container offices give you a secure, weather-tight workspace that can be set down on a job site, farm, yard or commercial lot without a traditional construction project. Built from steel shipping containers, they are commonly used as site offices for contractors, sales offices at equipment and car lots, security and gate stations, dispatch rooms and temporary administrative space during renovations.
Because the steel shell is already rigid and lockable, a portable office can be moved again when a project ends, which makes it a practical choice for businesses that relocate between sites.
Common Sizes and Layouts
Container offices are typically built from 10, 20 or 40 foot containers. A 10 foot unit usually suits a single desk or a guard station. A 20 foot unit typically fits one or two workstations, or a small office with a storage area behind a partition. A 40 foot unit can often be split into a private office, an open work area and sometimes a small restroom.
When comparing listings, look at:
- Insulation type and whether walls and ceiling are fully lined
- Electrical package, including outlets, lighting and panel size
- Heating and cooling, such as a mini-split or wall unit
- Number and placement of windows, plus security bars or shutters
- Personnel door type and lock hardware
- Interior finish, flooring and whether plumbing is included
Preparing Your Site
A container office should sit on level, firm and well-drained ground. Compacted gravel, concrete pads or engineered blocks under the corners are common choices. Uneven ground can cause doors to bind and windows to rack, so it is worth leveling the area before delivery.
Plan how you will connect power. Many units are wired to plug into a temporary pole or a permanent service, and a licensed electrician should handle the final connection. If the office includes a restroom, you will also need water and a sewer or septic connection.
Delivery and Local Rules
The delivery truck needs a clear, straight approach with enough room to maneuver and no low wires or branches overhead. Some heavier or finished units may need a crane or forklift at the site, which we will discuss with you before delivery.
Before ordering, check with your local zoning office and building department, and review any HOA or property owner rules. Requirements for portable offices vary by location and by how long the unit will stay in place.
How Ordering Works
The container offices listed on this page reflect units currently available. Choose the one that fits your needs and place your order online.

Container Offices FAQs
What size container office do I need for a small crew?
For one or two people working at desks, a 20 foot container office is typically enough. If you need a private office plus a meeting or plan table area, a 40 foot unit usually gives more flexibility. Think about storage, restroom needs and how many people will be inside at the same time before choosing a size.
Can a container office be connected to permanent power?
Yes, many container offices are wired so they can be connected to a temporary power pole or a permanent electrical service. The final hookup should be done by a licensed electrician who can confirm the panel size and wiring meet your local code. Ask our team about the electrical package on any listing you are considering.
Do I need a permit to place a portable office on my property?
It depends on your location and how the office will be used. Some areas treat a portable office as a temporary structure, while others require a building permit or zoning approval. Check with your local zoning office, building department and any HOA or property owner before delivery so there are no surprises.
When do I pay for a container office ordered online?
You place your order online first, and then our team reaches out to confirm the unit is available, the final price, tax and delivery arrangements. Payment is only requested after you have reviewed and agreed to those details, so you know exactly what you are paying for before anything is charged.
