Building on a tradition of innovation

Factory_OS is located on Mare Island,  a place where generations of fearless Americans have faced our country’s most intractable problems and changed the course of history with dignity, innovation and grit. It is a tradition we intend to continue.

Bringing transformational change to a  stagnant industry

The iconic Building 680 is the famous Mare Island Naval Shipyard machine shop where determined Americans rebuilt the Pacific Fleet after the attack on Pearl Harbor. Today, Factory OS is channelling this powerful history into a new, pressing social and political problem that impacts millions of Bay Area residents and Americans across the country: The lack of more affordable housing.

We build well-designed, tech-ready multifamily homes 40-50% faster and 20-40% less expensive than conventional housing. These savings are proven, not projected. We do this by building the bulk of the home off-site, right down to the toilet paper holders. Then we ship it and assemble it on-site.

A holistic approach to building & construction

This process brings relentless efficiency to a profoundly inefficient industry. In Building 680, Factory_OS can build homes year-round, rain or shine, leveraging the proven principles of lean manufacturing and cutting-edge software technologies. Quality control is better. Workers are safer. Precision cutting and indoor material storage reduce construction waste by more than a third, and reduced transportation requirements lower carbon emissions, making this the greenest building method available today. On-site assembly is faster, cleaner and far less disruptive to our neighbors.

Factory_OS is taking bold, meaningful steps toward meeting the critical need for more affordable apartments and condominiums in our cities. Starting now.

Creating a 21st century union, made by local full time workers

Our homes are Union Made. We are committed to progressive labor practices and built on a strong relationship with the Northern California Carpenters Regional Council. We have a unique agreement with the union to recruit and train local workers, and FactoryOS will create more than 300 permanent, full-time construction jobs that pay up to $60,000 per year  and provide full health and retirement benefits.

We’ve found a better way

Like the shipbuilders who came before us, Factory_OS is taking up one of the most urgent and important challenges of our time. This is the story of a forward-thinking team of modular home manufacturers who are dedicated to transforming an industry, creating jobs, and building more affordable housing for owners and renters alike.

Meet the Team

Supporting integrated in-house research and innovation

The top floor of the factory is home to the Factory_OS Housing Innovation Lab. The center’s work will be fully integrated into the manufacturing process in an unrelenting effort to improve efficiency and get the cost of home construction down even further. We are partnering with local universities and research centers to leverage our work.
