Oxford House is a concept in recovery from addiction and alcoholism. In its simplest form, an Oxford House describes a democratically run, self-sustaining, drug-free house. This publicly supported nonprofit 501(c)3 corporation is an umbrella organization that provides a connection to all Oxford Houses' Network and allocate resources as needed to replicate the Oxford House concept. The number of residents in a house can range from six to fifteen; There are homes for men, homes for women, and homes that accept women with children. Oxford houses are flourishing in major cities like New York City and Washington D.C. and thrive in communities as diverse as Hawaii, Washington State, Canada and Australia; but they meet all the basic criteria. Each House is an amazingly effective and inexpensive method to prevent relapse. This was the purpose of the first Oxford House established in 1975, and this purpose is fulfilled, day after day, house after house, in each of the more than 2000 houses in the United States today.
