Which Company to Choose

Some companies focus on speed and simplicity, while others offer broader model selections or support for DIY installation. In contrast, stick-built ADUs are fully customized and constructed on-site.

It is often the preferred approach for larger ADUs or when properties have slopes, tight access, or unique zoning challenges.

A Streamlined Approach to Construction

ADUs are also seen as an environmentally friendly housing option. They typically require fewer resources to build and maintain compared to new single-family homes. Moreover, ADUs can contribute to more sustainable urban development by increasing density without the need for sprawling new developments. This can reduce the overall carbon footprint of housing in California.
