“Occasional home-sharing and occasional home rentals have been going on for decades, and without question they provide real benefits to the teacher, student or grandmother who may want to earn extra cash,” said AH&LA president and CEO Katherine Lugar on a press call on Wednesday. “That is not our focus today. Instead, this report revealed a very different and very disturbing trend.” The report, “From Air Mattresses to Unregulated Business: An Analysis of the Other Side of Airbnb,” conducted by Penn State University’s School of Hospitality Management, analyzes data from Airdna, which tracks Airbnb revenue and operations through continuous searches of the Airbnb site. The data was gathered over a 13-month period in 12 major U.S. markets and excludes all shared rooms and apartments, as well as unique units, such as boats, tree houses and tents. A key finding of the analysis was the rise of mega-operators, defined as “hosts” who rent out three or more units. They grew from 1,171 in September 2014 to 2,193 in September 2015, an 87.3 percent increase. Mega-operators account for 7 percent of hosts in the markets studied—New York City, Chicago, Los Angeles, Philadelphia, Miami, Houston, Dallas, Phoenix, San Antonio, San Diego, San Francisco and Washington, D.C.—but accounted for 25 percent of revenue generated in those markets, totaling about $326 million.
