How this layout works

• Conference room at the left end (12’x14′)
• Open office with 4 workstations
• Kitchenette counter with sink and microwave space on the rear wall
• Single-user restroom (5.5’x6′) in the rear corner, with the toilet on the exterior wall
• Manager office at the right end

Like every iModular.com plan, this 14’x64′ office trailer floor plan follows a few rules: wall-mount HVAC units sit on the end wall, and that wall has no windows; toilets and sinks are on exterior walls, which keeps plumbing runs short and costs down; restrooms have no windows. Also, every layout can change. For example, we can move walls, doors and fixtures before the factory builds a new building, and a contractor can often remodel a used one after delivery.

What a 14’x64′ office trailer is used for

For example, buyers often choose this layout for uses like these. However, the same layout works for many other jobs, too.

• Larger job site offices with a conference room
• Sales and leasing offices
• Temporary administration offices
• Training or meeting space for a crew

Delivery and site setup

A 14’x64′ office trailer rides on its own steel chassis with axles and a hitch, so a truck tows it to the site in one piece. However, at 14′ wide it is an oversize load. Plan on state transport permits, and many states also require pilot or escort vehicles at this width (see how Florida handles escorts). Once it arrives, the crew levels it on piers or blocks, anchors it with tie-downs and adds steps at each door. However, utility hookups are by others.

As a result, the site work for this building usually comes down to a level pad, a foundation, utility hookups and access. Also, ask your city or county early, because local permits often set the schedule.

Approvals where you are

In short, the building in this 14’x64′ office trailer floor plan is the same everywhere. Instead, what changes is the state program that approves it and how your city or county permits the site work. For example, in California the Department of Housing and Community Development (HCD) approves commercial modular buildings (California prices and guides). In Texas, the TDLR Industrialized Housing and Buildings program covers them (Texas guide). Similarly, Florida uses the DBPR manufactured buildings program (Florida guide). Either way, iModular.com brokers modular buildings nationwide. Read how permits work for modular buildings.

Frequently asked questions

How many square feet is a 14’x64′ office trailer?

A 14’x64′ office trailer has 896 sq ft. In this 14’x64′ office trailer floor plan, we measure the 14’x64′ box, so the hitch adds about 4′ to the overall length but no floor space.

How many people can work in a 14’x64′ office trailer?

This layout has desks for 5 people. However, for exits and restrooms, the building code counts business (B) space at 150 sq ft per person, which gives a code occupant load of about 6.

Does a 14’x64′ office trailer need a ramp?

Usually not. Most codes do not require a ramp on a job site office trailer, so this plan shows steps. However, if the trailer will serve the public, such as a sales or school office, plan on an ADA ramp and landing.

Can a 14’x64′ office trailer have a restroom?

Yes. In fact, this layout includes a single-user restroom in the rear corner, with the toilet on the exterior wall. Also, plan on water and sewer hookups on site.
