Build an ADU

Attached ADUs strike a great balance between affordability and functionality while maintaining a strong connection to the primary home. Since they share a wall with the main residence and often utilize existing infrastructure like foundations and rooflines, attached ADUs typically require less investment to build. Attached ADUs are especially practical if you have some existing living space, such as a basement or bonus room, that you want to incorporate into the ADU.

Detached ADUs make the most sense for properties with ample yard space and for homeowners seeking maximum independence between the primary home and the secondary unit. While they tend to be the most expensive type of ADU due to the need for constructing a new foundation and roof, their benefits often outweigh the costs. Detached ADUs provide the most flexibility in design, privacy, and customization, allowing homeowners to create a unique and functional space tailored to their specific needs.

Converting a garage into an ADU is often one of the most budget-friendly options since the foundation, walls, and roof are already in place and with thoughtful design, a garage conversion can seamlessly blend into the property. This approach maximizes the use of underutilized space and transforms it into a functional living area. Key features to assess when planning a garage conversion include the condition of the existing footings, plumbing, and electrical systems, as these can significantly impact renovation costs and feasibility.
