The article cites multiple YIMBY laws and political accomplishments. Has there been enough time passed to determine if these laws and abolishment’s of wasteful land use has resulted in less homelessness, more affordability, etc? I’m legitimately curious here. I’m also curious what the perhaps unintended side effects are of this. I can imagine eg. Where you don’t have to mandate two parking spaces for a 2 bedroom apartment, the landscape of the city changes additionally where car owners feel less welcome (less parking available) which might be actually a great thing, but I want studies to prove this out. To be clear, I support policies that theoretically decrease homelessness and increase affordable housing. I too have difficulties acquiring housing. I want to know these policies actually have evidence now that they’ve been enacted.
