In New York State there are currently 25 not-for-profit homelessness prevention services. The majority of these programs began servicing clients between March and May of 1990. Most of the clients served by the Homelessness Prevention Program are in the late stages of the eviction process. In all but two programs, the majority of clients have been served with eviction notices or received eviction notices while in the program. In addition to offering program descriptions, this report provides estimates on the number of prevented evictions and prevented homelessness, the cost efficiency of these programs and the net savings associated with the Homelessness Prevention Program.
