What Types of ADUs?

Use the ADU Marketplace to decide what type of ADU works best for your property and your needs.


Most popular are detached ADUs in the backyards, think of granny flats, in-law units. Attached ADUs and expansions also fall into this category.


Most homes are able to convert existing space of some sort into an ADU, be it a garage, an extra bedroom, or a basement. Some cities also allow Junior ADUs, so check your city to learn more.


If your property already has an ADU of some sort you should consider adopting it to code and legalize it. For rental, safety and in case you want to sell your property.
