On November 14, 1884, New York State legislature passed the Tenement House Act, a landmark legislation aimed at improving the dreadful living conditions in immigrant tenements. The law mandated proper ventilation, minimum window requirements for every room, fire safety measures, and basic sanitation standards. This was the state's first comprehensive attempt to regulate tenement housing, which housed thousands of poor immigrant families in overcrowded and unsanitary conditions. The act required landlords to provide adequate light and air to all living spaces and established minimum room sizes, marking a significant step toward recognizing housing as a matter of public health and welfare.

On November 14, 1955, the Karachi Development Authority (KDA) officially launched North Nazimabad, Karachi's first properly planned residential township. Designed to accommodate the growing middle-class population in Pakistan's largest city, the project featured wide roads, proper drainage systems, designated commercial areas, and public parks. The township was planned with a gridiron pattern and included various block sizes to cater to different income groups. This development set new standards for urban planning in Pakistan and became a model for subsequent residential schemes in Karachi, demonstrating the government's commitment to organized urban expansion during the country's early years.
