Airbnb’s peer-to-peer rentals are being scrutinized in Los Angeles; Miami Beach, Florida; Portland, Oregon; Toronto; Barcelona; and Berlin. In its hometown of San Francisco, a federal judge on Nov. 8 upheld rules could levy hefty fines on its platform. In New York, the company’s largest US market, governor Andrew Cuomo in October signed into law some of the toughest limits on short-term apartment rentals in the country. The backlash comes right as Airbnb is looking to transform itself into a full-service travel firm, and as it inches toward an inevitable IPO. The company isn’t taking it well—its lawsuit against Santa Monica was one of four complaints Airbnb lodged against US cities this year.
