Tenement housing refers to a type of residential building or structure that typically includes multiple dwelling units within a single property. These units are often small and compact, accommodating lower-income families or individuals. Tenements can range from large apartment complexes (🏢) to smaller multi-story buildings (🏠) or even dilapidated structures (🏚️). They are characterized by their dense occupancy and often lack amenities commonly found in modern housing developments.
