Ok, I'll add to the pile on. This article was a clumsy attempt to make a valid point about the need for more housing via a breezy account of two superficially similar neighborhoods. Miami and SF really are two very different beasts. The underlying demands are vastly different. SF is a far wealthier MSA with a much more dynamic economy.
The Bureau of Economic Analysis on cost of living adjusted personal incomes by MSA. In 2011, raw per capita income was 61k in the SF MSA vs. 43.1k in the Miami MSA. But even when they adjusted for differences in cost of living, people in the SF MSA still earned 25% more than in the Miami MSA.

When comparing the cities themselves, SF is easily the far wealthier city. Median Household income in Miami is 30.4k vs. 75.6k in SF. When you compare housing costs to income, households spend 26.5% of their income on housing in SF vs. 39.2% in Miami. Even among just renters, renters in Miami spend 46.4% of their income on housing vs. 31.1% in SF.

So housing to income costs are actually lower in SF than in Miami!!!
Of course this isn't to attack Miami. Yes, it lacks a SF or even Minneapolis style based knowledge economy. That drives downs its income and education levels. But, it is also a major point of entry for immigrantion. Nearly 70.5% of Miami’s adult pop (over 25) is foreign born vs. 41.5% in SF. Now immigrants tend to earn less money, so we would naturally expect that to pull down Miami’s averages. This is magnified by the fact that immigrants in Miami tend to be lower skilled than those in SF. The average immigrant man in Miami earns 57.9% of what a native born man in Miami earns. In SF, the average immigrant man earns 63.4% of a native-born person. The relative earnings gaps are even larger among women, 62.5% in Miami vs 71.2% in SF.
Plus there is the fact that Miami is less densely populated, with more vacant land available for redevelopment. SF is tightly packed with 3-story flats on small plots that do not lend themselves well to higher density redevelopment.
So yeah, it really is an apples and oranges comparison.
All that being said, the author did make a valid point that restrictions on development push up prices and SF could allow more development. I just wish he had cited some credible studies instead of writing a “pop” economics piece based on walking around a couple areas. This is as bad as the authors who compare rents in new buildings to older apartments and conclude that it is development that is pushing up prices.
