API Trailers has years of experience providing cost-effective, well designed modular buildings to our customers throughout California. See what our satisfied customers say about API modular construction.

A pre-fabricated, factory built modular building can provide you with customized floor plans to meet both your permanent and temporary space needs.

A benefit of modular construction is while your modules are being designed then built in our factory, your site work, and permitting process can occur at the same time. This permits earlier building occupancy and contributes to a much shorter overall construction period, reducing cost and saving time.

Once your modular building construction is completed in our factory, it is delivered to your completed site.  When our team of experts is done putting your building modules together, the  architectural details of your modular building are added.  Upon completion your modular building is indistinguishable from a conventionally constructed building. (See our Project Gallery)

Our pre-fabricated modular buildings, can be used for many purposes, including, but not limited to:

  • office space
  • sales offices
  • portable classrooms
  • residential homes
  • commercial buildings
  • retail space
  • senior centers
  • healthcare facilities
  • churches
  • government buildings
  • cabins
  • barracks
  • tasting rooms
  • fire stations
  • court rooms
  • addition to your existing building
“Thanks again for your diligence and attention to detail and quality on the Bike Shop. You’ve got a great crew. Please pass it on that the building looks great and the project is well received. When the opportunity presents itself, I have it in mind to get you involved in one of our projects, something contemporary, green and innovative with solar.”
Wm. Howard Wittausch,, UCSB Bike Shop
“From design to delivery, API handled all of the details and changes to our satisfaction. During the installation process, API’s staff could not have been more professional and courteous. We have been in our new office coming up on a year, and we couldn’t be happier with how everything turned out.”
Aaron J. Cisney, General Manager, Rancho Guadalupe, LLC
From beginning to end, API worked well with us to allow our dream of a much needed and cost effective facility to become a reality. From the original meetings, design work, answering our numerous question, through the actual build, we felt more like partners than customers. We recommend Mr. Martino and his team at API to you without reservation.”
Pastor Bernie Federmann, Lead Pastor, Lompoc Foursquare Church
On behalf of the Board of Directors and the entire Vaqueros De Los Ranchos membership, we would like to express our thanks and appreciation for loaning us the Security Office Trailer. The Vaqueros are fortunate to have a generous Company like yours in the area to help make our ride sucessful.
Curt Reade, Vaqueros De Los Ranchos
I can’t tell you enough how great it was working with you. It went so smooth. The trailers are top notch. Your delivery guys are so courteous and professional. Thanks again. We’re looking forward to our future years with you.
Lesa John, Paso Robles Event Center/California Mid-State Fair
Earlier this month, I required some maintenance on the trailer and call API for help. I was put in touch with Jim Arkinson, who handled the job. He turned around a price quote immediately. After making some additions to the original quote, I authorized the work. A crew was immediately dispatched and did an excellent and professional job. I am well satisfied with the result. I want to compliment API on it’s attention to customer service. Your entire staff, including the receptionist, work crew and especially Jim Arkinson, made me feel that API truly valued by business, even though mine was a small job relative to the work you usually do. Previously to starting my own business, I was vice president of marketing at a high technology company. As a result, I recognize that API’s focus on customer service is a direct result of the commitment of senior management to it’s customers. My compliments to you and your staff.
