Riis led to the formation of tenement housing commission and also led to the formation of tenement housing board to solve problems like crowding, small houses, no access to sanitation.
<u>Explanation:</u>
Tenement housing was a necessary for the people living in that area in the United States of America because the houses they were living in originally were in very bad conditions and did not have much facilities like sanitation, light, air and so on. They were very very small in sizes leading to the suffocation of the people living in those houses.

With these houses, the problem of crowding of those people would have ended and the tenement houses also had the facilities of light and air. There was also access to sanitation.
