More like a straw army.

Austin is surrounded by empty flat land. San Francisco is surrounded by water and was built out many decades ago.

London suffers from being the main city in Britain. The UK is overcentralized. Most of the money and power are in London. Some countries are centralized like that, with all the good stuff around the national capital. France, Japan, and Russia are; the US, Canada, and China are not. (China, maybe; too much is near Beijing, but there are lots of other big cities.)

This^^^. The idea that housing starts are solely (or even substantially) impacted by regulation is a case of control bias, attributing disproportionate influence to minor factors we can control (like regulation) over major factors we cannot (land, labor and material costs).

I've read this like 5 times and I still can't make sense of it. Is this a variant of the "5-bedroom houses in Cairo Illinois only cost $40,000, there is no housing shortage" argument?

[vannevar]

No---did you read the original article? The comment and the parent will make more sense. Basically the article compares Austin and San Fransisco and attributes the difference in building rates entirely to disparities in regulation. Which is obviously not an accurate framing, for the reasons mentioned in our respective comments.

Your comment is more addressed at affordability, which is largely a function of wealth disparity: as the wealthy get richer with respect to the lower percentiles, they absorb an increasing share of the home market and drive prices up.

I did; the top comment on this thread is my response to the article. I don't think you fully get the argument: San Francisco needs to upzone and do large amounts of infill development. Most of the most important areas of economic opportunity in this country are landlocked; San Francisco's challenge isn't unique.

[vannevar]

I think you're making the same mistake the article did, focusing on the regulatory environment. My argument is that the zoning and other regulation is not the main reason Austin has more housing starts than San Francisco. The main reason is that land, labor, and materials are cheaper there. SF can upzone and infill to it's heart's content, it won't make land, labor and materials cheaper than Austin.

[tptacek]

Your argument is conclusory. The whole question is the extent to which the regulatory environment is preventing upzoning. If you think San Francisco should remain zoned the way it is, say that, and say why.

SF still has lots of low density that could be demolished in favour of higher density housing though.
