A tenement is a type of building shared by multiple dwellings, typically with flats or apartments on each floor and with shared entrance stairway access. Wikipedia

Building with several storeys accommodating dwellings set above each other. In Scotland it is a well-regarded form of urban living including new tenements built recently, but in many other English-speaking areas, the term commonly refers to a substandard multi-family dwelling in the urban core, usually old and occupied by the poor.
