Meaning
In Boston housing talk, a triple-decker (also three-decker) is a three-story multifamily house traditionally arranged with one dwelling on each floor, a building type strongly associated with Boston neighborhoods and the wider New England built environment.
How it is used
Triple-decker and three-decker appear in ordinary Boston housing, neighborhood, planning, architecture, and real-estate discussion. The term names a recognizable multifamily building form rather than merely any building that happens to have three floors.
Examples

- “That block still has rows of three-deckers with front porches.”

Visitor guidance
Visitors are likely to encounter triple-decker or three-decker in discussions of Dorchester, Roxbury, Mattapan, and other Boston neighborhoods. The building type is not exclusive to Boston, so the term should not be presented as a Boston-only invention or slang performance.
Cultural context
Boston.gov describes the triple-decker as an iconic Boston housing type and traces its growth from the late nineteenth into the early twentieth century during major population and immigration growth. The form remains part of current housing and planning discussion, while related three-decker housing also appears elsewhere in Massachusetts and New England.
