The data, in a report released by CBRE Hotels (formerly PKF Hospitality), suggests stiffer-than-expected competition for developers of new hotels in major markets such as New York, Los Angeles and San Francisco. In New York, Airbnb units accounted for almost 23,000, or about 16%, of the 140,000 total lodging units (hotel and Airbnb inventory combined) as of September, the most recent month tracked in the study. The CBRE study found that Los Angeles’ 13,000 Airbnb accommodations accounted for 12% of that city’s lodging units, while Airbnb units in San Francisco and Miami comprised 11% and 9.2% of those cities’ lodging units, respectively. For the study, CBRE culled data from both STR and Airdna, which provides data to vacation rental entrepreneurs and investors.
