What type of ADU should you build?

When determining the type of ADU to build, it’s important to consider your specific needs, property layout, and local regulations. There are various options available, including attached ADUs, detached ADUs, garage conversions, basement ADUs, and junior ADUs.

The ideal type of ADU for you will depend on factors such as your budget, available space, desired level of privacy, and local regulations. Consulting with professionals like ADU Builder can help you assess your options and make an informed decision that aligns with your goals and property constraints.
