I'm sorry, that's just not true, and Sam, I admire a lot of what you've said on a lot of issues, but I cannot believe that you are sincere in this article overall, unless you are just naive.
Any property owner in San Francisco has always been able to go to the Planning Commission and request a conditional use permit to turn their home into a bed and breakfast, and as far as we can tell, no such request has ever been denied.
Renters in San Francisco do not in almost any case I have ever heard of have the right to sublet our apartments, even to additional roommates, without the approval of our landlords, and with good reason.
If a person has lived in San Francisco for some time, and loses their ability to earn enough to pay their rent, it is abusive and narcissistic for that person to believe that simply by having the keys to a place that already does not belong to them, they can - with no consideration for their neighbors - turn their home into a business. A hotel business, no less, which kind of foists upon them the responsibilities of travel guides, as we read in an article this morning.
Now, as demand for housing in an area is shooting up, individual renters are leveraging that in a way that does not contribute to the cost of maintaining property, putting increased pressure on other tenants, and disallowing the landlord from actually satisfying that demand.
All that aside, AirBnb knows what the fuck they are doing. I know at least one successful AirBnb host who has had AirBnb approach them and encourage them to rent up nearby apartments and turn them into new units!
San Francisco housing activists have asked time and time again for AirBnb to open up data about how many hosts have multiple units, and who is renting when not in their unit, so that data may be used over time to guide regulation, but as is becoming a trend with YC companies, private executives and investors feel that they can do better city planning than people who have decades or perhaps their entire lives invested in doing so.
Put up or shut the fuck up, sir.
