Which of the following was a provision of the Tenement Housing Act of 1867?

The Tenement Housing Act of 1867 included provisions aimed at improving living conditions in tenement buildings, which were notorious for being overcrowded and unsanitary. One of the key provisions was that all rooms used for sleeping must have a ventilating window. This requirement was crucial for ensuring adequate ventilation and light in the sleeping areas, which directly contributed to the health and comfort of the inhabitants.

Having a ventilated sleeping room helped to reduce the buildup of stale air and moisture, minimizing the risk of respiratory issues and promoting a healthier living environment. This provision highlighted the growing awareness of the importance of airflow and sanitation in reducing disease spread, especially during a time when industrialization was leading to increasingly crowded living conditions in urban areas.

The other options, while addressing various aspects of building safety and sanitation, do not accurately reflect the specific provisions of the Tenement Housing Act of 1867. The act primarily focused on ventilation and light as fundamental aspects of living conditions in tenements.
