By the numbers, SF simply isn't building fast enough, nor has it over the last 20 years.

  Units built in 2014: 3,514 
  Jobs created in 2014: 23400
  Permitted units (at any stage): 3756
  Submitted units for review (not permitted): 8000

Further, many of the buildings are squat, short, and low density, even near transit. SF suffers from 20 years of planning failure.

Read the last 10 Socketsite articles to get an idea how criminally mismanaged SF's planning is. The AirBNB regulations are to make the city's power brokers look like they can do something about growth other than build.

For comparison: Manhattan issued permits for 4,856 new housing units in 2013 [1], despite having half the land area of SF and already supporting 4 times the population density.
