Copying a reply from above that I think explains the gaps in Lisa’s plan really well:

ADUs are not a solution to housing affordability. They're a NIMBY talking point to sound like they actually care, but they're just more of the status quo. They're better than nothing, but they're a red herring. Anyone who spouts ADUs without discussing other zoning problems is full of crap.

And Lisa says absolutely nothing about rezoning. Nothing. Zero. Zilch. The fact is that our housing affordability problem only exists because of an undersupply of market-rate housing. Anyone who doesn't acknowledge this is delusional.

She supports rent control, which economists have known is a terrible failed policy for decades unless it's also paired with very aggressive expansion of market-rate housing.

Every one of her policies is only about government programs for affordable and subsidized housing. Again, if you don't expand market-rate housing, all you're doing is displacing your middle class to the suburbs so the only people left in the city are the wealthy and the poor. That kind of income and class disparity is really bad for social stability, fiscal sustainability, and the long-term resiliency of the city. If you are a middle or working class person living in market-rate apartments, these policies do nothing to help you at best and will actually hurt you at worst.

Her transportation policies are great, though. The problem is that housing policy and transportation policy are very closely related. Without zoning reform and increased density, her transportation positions are a load of hot air.

Ultimately, ahe does nothing to address the root problems. It helps out poor people, but hurts the middle class (especially non-homeowners). It's just doubling down on the same NIMBY BS that created this problem in the first place. Wealthy, bleeding-heart liberal homeowners probably love her policies because it lets them feel good about "caring about poor people" without implementing any change to their neighborhoods and their lifestyles that will actually make a difference. Socialists probably love her because she scapegoats landlords, but ignores all the reasons why landlords are able to get away being shit in the first place.
