I have no idea where you are getting your data. Zoning density restrictions and overuse of historic landmark status create artificial scarcity of land resulting in higher housing costs. These both create market failures in housing.

In Japan for 20 years there have been federal laws overriding local law that restricts zoning density. The result: in Tokyo they have been building 140,000 housing units per year compared with 20,000 in NYC and 90,000 for all of California. The cost of housing as not increased at all in the past 20 years because these market failures (in this case also called "rent-seeking") in real estate are not allowed to occur in Japan.

We need similar laws in the US as Japan.
