Build Faster.  Build Smarter.  Build Prefabricated.

Fullerton Building Systems is a third-generation, family-owned business that has evolved over 75 years from origins in the lumber yard into a leading custom commercial construction company that uses state-of-the-art prefabricated building processes. Throughout Fullerton’s existence we’ve focused on excellent quality, consistency and customer service — and these days we’ve been able to add speed to the list. 

Using an overbuilt, engineered and smart prefab construction process, we are able to supply and install commercial buildings at a rate that others just can’t match. On average, businesses we build open 60 days earlier than they would with traditional construction. Even better, our process means no change orders, shorter construction schedules, fewer labor shortages and less chance of on-site safety risks.  

During every project, we act as an honest and reliable partner to corporate construction teams, franchisees, developers, general contractors, architects and engineers, making our process much more efficient than other methods. Our company-wide commitment to reliable partnerships, combined with proven prefab building techniques and our top-notch team have made us a trusted name in the commercial construction industry.
