The problem is that the city government artificially limits supply through zoning. If the zoning were changed, the market could easily supply a lot more housing, perhaps looking like this: https://maps.google.com/maps?q=park+slope+brooklyn&ll=40.77913,-73.978782&spn=0.011163,0.022638&hnear=Park+Slope,+Brooklyn,+Kings,+New+York&gl=us&t=h&z=16&layer=c&cbll=40.77913,-73.978782&panoid=9dhb9Bvs7u3mZ8CyIpEerQ&cbp=12,271.99,,0,-2.99 https://maps.google.com/maps?q=park+slope+brooklyn&ll=40... or this: https://maps.google.com/maps?q=barcelona&ll=41.389334,2.156582&spn=0.01106,0.022638&hnear=Barcelona,+Province+of+Barcelona,+Catalonia,+Spain&t=h&z=16&layer=c&cbll=41.38941,2.15669&panoid=jnpJt1xYjLXS8xNcm4VC6Q&cbp=12,72.34,,0,-14.08 https://maps.google.com/maps?q=barcelona&ll=41.389334,2.... Instead of limiting things to this: https://maps.google.com/maps?q=san+francisco&hl=en&ll=37.755337,-122.487248&spn=0.005794,0.011319&hnear=San+Francisco,+California&gl=us&t=h&z=17&layer=c&cbll=37.754976,-122.48727&panoid=GbHFSk1_NQa_EKgG64lU7w&cbp=12,98.66,,0,-1.45 https://maps.google.com/maps?q=san+francisco&hl=en&l... The NYC & Barcelona examples can hold 5 or more families in the space that one takes up in the SF example. Both are very desirable places to live.
