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 seperate unit additions are also included in 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 updating it to code so it can be permitted. This will allow the unit to be rented out or sold for it's full potential market value.
