Since the early 1970s, community associations—condominium associations, cooperatives, and homeowner associations—in the United States have experienced exponential growth. It is anticipated that this growth will continue for the foreseeable future for generally the same reasons as in the past—that is a combination of regulatory pressures as well as the need for a housing alternative that offers not only a wide range of pricing options but also an array of services and activities not generally available with a single-family home purchase. To put this growth in perspective, while it is estimated that 13 percent of the residential housing in the United States is in some form of community association, 80 percent of all homes currently being built are in associations. This 13 percent represents 249,000 associations and nearly 20 million individual units nationwide. Assuming that each unit houses only two residents, this would mean nearly 40 million residents. Realistically, this number is closer to 50 million as the average household contains more than two residents.
