What social issue did the Tenement Law of 1879 address?

The Tenement Law of 1879 primarily aimed to address the issue of overcrowding in urban areas, particularly in New York City. During this period, many immigrants and low-income families were forced to live in severely cramped conditions within tenement buildings, which often lacked basic sanitation, adequate light, and ventilation. This law mandated that tenements have a certain number of windows for every room, ensuring better air quality and light access, as well as requiring fire escapes for safety.

By implementing these regulations, the Tenement Law sought to improve the living conditions for the urban poor and mitigate the health hazards posed by overcrowded and poorly maintained housing. This legislation was a significant step toward addressing the widespread problems associated with urbanization during the late 19th century, highlighting the socio-economic challenges faced by residents of these tenements.
