American Modular Systems

California’s Leading Modular School Manufacturer

Family owned and operated since 1983

The more things change, the more we don’t.

A lot has changed in the past 43 years. Our buildings are more advanced. Our process is more efficient. Our factories have grown. What hasn’t changed is the integrity of our company and our commitment to building the best environments for students and teachers. When you build with AMS, you’re going to get the highest quality modular buildings, backed by end-to-end personal service. It’s how we started our business in 1983, and it’s how we do business today.

Our Story
Solutions You Need
Our buildings are designed to meet the most important needs. Yours.

Every AMS building starts with the same goal: meeting your project needs. We offer a full range of flexible building solutions that can be designed to your exact requirements. We build what you need… when you need it… at a cost you can afford.

Project Certainty
Build with AMS. Build with confidence.

It takes confidence to navigate an unpredictable market, the kind that comes top-down from experience and a clear sense of purpose. While other companies are branching out, AMS is committed to being the best at just one thing: building modular schools. We’ve delivered more modular school buildings than any other company in California, and we’ve delivered them on-time and on-budget. In times of uncertainty, we deliver project certainty.
