Arntz Builders is a Northern California public works general contractor.








Arntz Builders, Inc. is a renowned specialist in commercial public works construction, serving Northern California with a rich history dating back to 1947. The Arntz family’s journey began after World War II when the ambitious Arntz Brothers, Larry, Gene, John, and Ken, founded Beacon Home Renewal Service to cater to the booming post-war economy. Their success led to the establishment of Arntz Contracting in 1958, specializing in public works projects throughout the Bay Area. In 1996, Arntz Builders partnership was formed, and in 2005, the company was incorporated, embarking on a shift towards alternative delivery methods of construction and completing its inaugural lease-leaseback project in 2008.

Our accomplished principals possess an impressive 175 years of combined experience in public works construction across Northern California. Alongside our highly skilled team, we have proudly completed projects exceeding a total value of three billion dollars since our inception. These include a diverse range of new builds and renovations, ranging from modest $1,000,000 projects to larger endeavors surpassing $47,000,000.

At Arntz Builders, we take immense pride in our team’s professionalism and ability to deliver projects at the highest standards specified in the contract documents while maintaining competitive value. Embracing cutting-edge technologies, we integrate modern scheduling and cost control practices to enhance all aspects of construction management.

While we cherish our heritage, our focus remains on the future. We continuously strive to better serve our clients and enhance our organization. As we transition into our third generation as a family-owned and operated business, our core principles of quality craftsmanship, unwavering integrity, and a steadfast commitment to our clients remain the guiding force that has shaped our business for over six decades.
