This isn't technically true. AirBnb likes to claim their hosts operate within the limits of the local laws. Even if you're not doing a full-time hotel, if you're a renter yourself you're almost certainly at least breaking the terms of your lease, and local SF law already makes renting a unit out for < 30 days illegal. AirBnB's make believe universe is about room sharing and couch surfing (all of which would be much more legal). But as much as they talk up the "sharing" aspect, >60% of the rentals shown in this article are for entire units, none of which is legal under current law. You can still defend the practice by saying you don't agree with the law. But AirBnB can't claim they expect their hosts to all abide by local laws when in this case it's clear that a majority of their hosts are not.
