Three units of residential housing stacked on top of each other. Ubiquitous in the urban areas of central and southern New England, especially Worcester, Massachusetts. Also known as triple decker.
"I grew up in a three decker on Grafton Hill. My grandparents lived on the first floor and my aunt lived upstairs."
