can also look at this criticism as giving examples of what we as a party need to improve in states where we have the power to do so.
I'm interested to read what you consider "intervening issues."
Just my opinion.
Also, I just found that CA has attempted to improve affordable housing. I haven't found anything about whether or not that's improved housing in San Francisco.
California is ending a rule that helped cause its housing crisis -- Gov. Newsom signed bills ending single-family-only zoning, a step toward addressing the housing crisis.

While overhauling single-family-only zoning might sound revolutionary, the bills are gentle attempts at increasing density: legalizing duplexes and quadplexes and making it easier to build small apartment buildings that provide up to 10 homes. This doesnt mean single-family homes are outlawed or can no longer be built, but it provides homeowners the option to convert their homes into duplexes or sell their homes to people who want to do so. Before now, it was illegal for someone to convert their home to a duplex on a lot zoned for single-family zoning. Not anymore.
This isnt a panacea for housing production. UC Berkeleys Terner Center for Housing Innovation found that SB 9 (the bill that legalizes duplexes) will modestly accelerate the addition of new units relative to the status quo. Other laws that restrict the building of new and more affordable homes are still in effect in particular, local laws around minimum lot sizes will continue to make it illegal to turn single-family homes into duplexes if the existing lot is too small to subdivide while still adhering to the size regulations.
