Why ADUs?

ADU stands for "Accessory Dwelling Unit" and is also commonly called a casita, guest house, pool house, back house, granny flat, etc. ADUs are an accessible form of affordable infill housing! 


Multi-generational Housing

Oftentimes casitas are used for extended family in order to age in place longer, or provide a safe place to land. From grandmas to nephews, brothers to kids home from college, there are many versions of multi-generational living that an ADU can help to support.
