Factory OS

Factory OS is a modular housing manufacturer based in the San Francisco Bay Area.

The company specializes in building multifamily apartments using an industrialized, off-site construction process. This approach allows Factory OS to create affordable, high-quality, and tech-ready housing more quickly and sustainably than traditional methods. Founded in 2017, the company operates from a 256,000 square-foot facility on Mare Island in Vallejo, California. Factory OS focuses on producing modular, stackable mid-rise apartment units, specifically targeting affordable housing, supportive housing, and student housing. The company has a pipeline of projects in cities like San Francisco, Oakland, and Los Angeles. Its construction method is designed for efficiency, resulting in units that are approximately 20% cheaper and 40% faster to build than conventional methods, while generating up to 70% less waste. With a production capacity of 1,500 to 2,000 homes per year, Factory OS aims to address the affordable housing crisis through innovative solutions and strategic partnerships with industry leaders.
