After the Manhattan urban development, the immigration impacted the population and economic in New York City. These changes brought consequences that led to the housing crisis problems like sanitation, plumbing, fire and diseases. The main priority of housing owner back in the 1800s was to figure out how could they fit more and more immigrants into their housing buildings in order to gain more monetary benefits. However, the tenants didn’t benefit from this because they were living uncomfortable and getting sick.

The bad use of the housing lots created issues for the tenants living in it. In 1899 the outlets maps show how inadequate were buildings organized in several places in New York City. At Halmiton street the housing buildings were badly arranged and put very close together because the landlords wanted to use all the land spaces. This brought too many problems and poorly decisions were taking which kept affecting the housing projects for many years.

The tenants were going through a tough situation since there were sanitation problems that lead to diseases issues within the housing buildings. There was a myriad of people with the contagious diseases called tuberculosis because of the lack of space and air flowing in these housing apartments since, some rooms were inappropriately design without windows. Indeed, the city wasn’t regulating air and sun during the urban development.

In conclusion the lack of organization and considerations during the housing project development started  many consistent issues which within the time were trying to be solved because of the tenement laws that were passed.
