San Francisco is the spiritual birthplace of Airbnb, the "Sharing Economy" service marketed for renting out excess rooms or your home/apartment when you're away on vacation.
However, according to Inside Airbnb data at November 1, 2015, the mjority of listings are instead for entire homes (4,033 of 7,029) and more than 1/3 of listings (2,490) are entire homes estimated rented out to tourists for more than 90 days of the year, in clear violation of the recently introduced short-term rental laws.
And more importantly, as San Francisco faces a housing crisis, short-term rentals permanently offered to tourists in residential properties are taking away housing from and displacing San Francisco residents.
The current short-term regulations in San Francisco have been found to be unworkable - the Agency enacted to enforce them has admitted there's "No way of enforcing" them. Hosts continue to rent out apartments permanently, and Airbnb is immune from any type of responsibility for facilitating housing disruption.
There are a number of initiatives to improve enforcement, specifically:
If you are concerned how Airbnb is impacting San Francisco:
On October 27th, 2014 Ordinance No. 218-14 was signed, amending the Administrative and Planning Codes to allow some residential properties to be eligible for short-term residential rentals. This law became effective on February 1st, 2015.
The criteria to be eligible to rent out a residential property for less than 30 days on platforms like Airbnb are:

How is Airbnb really being used in and affecting your neighborhoods?
Airbnb guests may leave a review after their stay, and these can be used as an indicator of airbnb activity.
The minimum stay, price and number of reviews have been used to estimate the occupancy rate, the number of nights per year and the income per month for each listing.
How does the income from Airbnb compare to a long-term lease?
Do the number of nights booked per year make it impossible for a listing to be used for residential housing?
And what is renting to a tourist full-time rather than a resident doing to our neighborhoods and cities?
An Airbnb host can setup a calendar for their listing so that it is only available for a few days or weeks a year.
Other listings are available all year round (except for when it is already booked).
Entire homes or apartments highly available year-round for tourists, probably don't have the owner present, could be illegal, and more importantly, are displacing residents.
Some Airbnb hosts have multiple listings.
A host may list separate rooms in the same apartment, or multiple apartments or homes available in their entirity.
Hosts with multiple listings are more likely to be running a business, are unlikely to be living in the property, and in violation of most short term rental laws designed to protect residential housing.
