From Lumber Yard Roots to Prefab Results

Fullerton Building Systems is a third-generation, family-owned company that has been helping businesses build smarter since 1882. What began as a network of 115 lumber yards has grown into a leader in custom prefabricated building systems.

But our story isn’t just about longevity—it’s about knowing when to change.

More than 60 years ago, we made a bold move that would define our future. We sold off the lumber yards and planted our roots in prefabrication—manufacturing building components off-site to streamline construction and accelerate timelines.

Even through decades of change, our focus has remained the same: quality work, consistent results, and strong customer relationships. Today, we’ve added another key advantage—speed—giving our customers a faster path to market so they can open sooner and start generating revenue faster.
