CNET reports that NYC officials have determined that Warren should pay $2,400 for "violating the city's illegal hotel law" and that apartments "may only be used as private residences and may not be rented for transient, hotel, or motel purposes" essentially making Airbnb illegal in New York (except for stays of 30 days or longer).
I like the service Airbnb is trying to provide. Is it contributing to higher rental prices in cities like San Francisco and New York and pricing out locals? Unclear. Does it provide an unsafe environment for neighbors concerned with strangers coming into buildings—another maybe, and Craiglist has already filled that role for some time now. We'll have to see what happens to Warren, and what the lobbyists end up accomplishing.
