Yes, the redevelopment of owner-occupied housing is a win-win if you believe that more supply reduces rent. Scott Wiener’s SB 50 in 2019 was exactly such a bill; it would have allowed redevelopment of owner-occupied housing into apartments, but it would not have allowed redevelopment of existing rental housing. However, Left-NIMBYs who fundamentally reject the benefits of private development will come up with any excuse (however specious) to oppose it. If you don’t think private housing has any value (or worse, if you think that new housing actively harms people), then you can always come up with excuses to prohibit it (e.g. by demanding that the government “value capture” it so that the developers won’t make any return on their investment on average). Here’s an example of an op-ed opposing SB 50 from San Francisco’s most vocal Left-NIMBYs: https://www.sfexaminer.com/opinion/how-the-state-can-help-cities-plan-for-density-with-affordability/ https://www.sfexaminer.com/opinion/how-the-state-can-help-ci...
