In Oregon, ADU eligibility can hinge on a property boundary that is easy to overlook: the urban growth boundary.

On a 2,400 square foot house, those two tests land in the same …
Building an ADU in Los Angeles can open up several possibilities, from creating a separate rental unit to adding private space for relatives or increasing the functionality of an underused portion of a property.
