About West Coast ADU
West Coast ADU is a dedicated ADU builder and accessory dwelling unit builder based in California. Their story began in the aftermath of the 2015 Northern California fires, when they were among the first to step in and support families who had lost their homes. That commitment to providing immediate, quality housing solutions became the foundation of their mission — to serve their communities with integrity and purpose.
Today, with California's more lenient ADU laws, West Coast ADU focuses on delivering high-quality homes for low-income families, in-laws, adult children, and caretakers. By utilizing prefabricated and manufactured construction methods, they are able to streamline both the permitting and building process, offering a faster and more cost-effective alternative to traditional home construction.
The Benefits of Building an ADU
There are many compelling reasons why homeowners choose to work with an ADU contractor like West Coast ADU. Here are some of the key advantages:
