That's absolutely it. The most absurd case is of course San Francisco, where literally one single building allowed by recent state law overriding local zoning is adding 100 years worth of total housing units and 15 years worth of affordable housing construction at current rates to the Marina district (https://www.sfchronicle.com/realestate/article/sf-safeway-to...), but the same problem exists in a lesser form across the state.
