This study examined the impacts of approximately 7,500 units of supportive housing in New York City. It found that supportive housing does not negatively impact neighbouring property values. The prices of properties within 500 feet of supportive housing actually increased, relative to the properties in the neighbourhood located further away. The prices of properties 500-1000 feet from supportive housing decline in value when a facility first opens, but prices soon increase steadily, suggesting the market realizes that fears about supportive housing are unwarranted. These results also do not depend on the size of the development, its characteristics, or whether it is located in a higher or lower density neighbourhood.
