Planners and urbanists love to come up with technical terms. For example, growing up in Hawaii, I lived in a house with a small cottage on the property. We called it our “ohana” unit.
Many years and one planning degree later, I now recognize that as an accessory dwelling unit (ADU). I can’t imagine a more technocratic shift, from ohana, meaning family in the Hawaiian language, to the robotic and jargony idea of a “dwelling unit.”
Likewise, there has been renewed discussion of accessory commercial units (ACUs) recently. A hundred years ago, these were simply referred to as “neighborhood groceries.”
