About Us

Our mission is to make it easy to build custom homes that are healthy, sustainable, and durable.

We manufacture custom single and multifamily homes that are high-quality, sustainable, healthy, and durable. We empower individuals, architects, and small developers who want to build their own projects – and who want an efficient and reliable solution. And peace of mind during the process. We work with your architects on your custom designs or you can work with our Design Partners or select Standard Homes they have created for us.

We are the first home factory in the nation dedicated to sustainable construction, materials, processes, and operations. We believe homes can and should be built in ways that minimize their negative impact on energy, water, resources — and the health of the people who live in our homes and who build them. We know that in-factory construction can be faster, more cost-effective, and more reliable than on-site construction. And we know it saves neighborhoods from months of noise pollution, traffic and disruption.

Plant was spun out of LivingHomes, a design and development company that’s built dozens of award-winning prefabricated homes, including the nation’s first LEED Platinum home.

Leveraging LivingHomes's experience with ten factories over the course of eleven years, we’ve learned a lot about what works and what doesn’t. Plant Prefab reflects many lessons and best practices. Major funding was provided by Obvious Ventures, a venture fund that focuses on #worldpositive investments. Our first factory is a 62,000 sf facility in Rialto, California.

If you'd like to discuss a project or if you have questions, comments, or feedback, we'd love to hear from you.

Some big things we value and practice. And why.

Design Matters

We love design. Good design makes you feel good, more productive, happy. We exist to make sure you’re able to build the design you want, efficiently, predictably and without compromise.

Health image
Health & Sustainability

As a company, we're committed to building homes that are as healthy as possible, and that minimize their "ecological footprint" with respect to the resources they use for their construction, operation and eventual decommission. Homes built using traditional stick methods can be very unhealthy and extremely resource intensive. We work with your Architects to integrate sustainable, healthier building materials, as well as energy-efficient environmental systems and products. And we use paints and stains that minimize off-gassing of harmful VOC's (volatile organic compounds) that might otherwise disturb your lungs or afternoon Darjeeling tea. We practice what we preach: we recycle vigilantly; employ non-toxic building and cleaning materials; and employ energy and water saving devices throughout our facility.

Modular construction image
Modular Construction

It's not your weird cousin's mobile home. Modular construction processes have been used to create long-lasting, high-quality office and industrial buildings, banks, schools—and homes for decades. In general, "modular" means that home construction takes place in a factory, before being assembled onsite in pieces or modules. Scandinavian countries, Canada and Japan all employ modular production as a major home-building technique. We use modular construction to build because it allows us to produce higher quality homes faster and with less cost and waste than traditional, "stick-built" (site built) methods.

Price value image
Price & Value

By building off-site in a lower cost region, our labor costs are typically significantly lower than the higher cost metro areas we often serve. And our floor staff are full-time workers, so we avoid the mark-up and management fees of sub-contractors. As a result, our total costs are often less than similar site-based projects — again, in high cost areas. Current budgets for projects we’re doing range from $130/square foot (larger multi-family project) to $200+/square foot for some of our higher end, steel framed residences. Because we do custom work, our fees will vary based on the project requirements. Regardless, we provide fixed price contracts and no Change Orders – unless you make a change.

Golden Rule image
Golden Rule

We think we should treat you – and each other – the way we expect to be treated. This means superior customer service; an industry leading warranty; and a commitment to our team that includes Living Wages, stock ownership for all employees, and extensive education and mentoring.

Dogs Rule image
Dogs Rule

We have employees who bring their dogs to work. We like cats, too, but no one has yet brought their cats. Maybe because of the dogs.

Through this company, Kevin was given opportunities to learn all aspects of construction and management. Kevin innovated several components that led to more efficient methods of construction and setting on site. He began his custom residential experience building homes for Michelle Kauffman and later co-founded Fedelity, a high-end modular home company to target this niche market. After four years and some very successful projects, Kevin joined Plant Prefab as the General Manager.
