I think a healthy balance is needed between helping renters and allowing developers to create housing, including affordable housing. If we place too many restrictions for landlords and developers, they will simply invest elsewhere, or only focus their efforts on high rent luxury rentals where they could actually turn some profit. There is a chance that these heavy restrictions could backfire, hurting renters. The lower supply of rentals could drive prices up even further over time. My main issue with Prop 21 is that it affects properties outside of multifamily like single family homes, hurting mom-and-pop landlords who consider their real estate investments to be their retirement plan or small business. I'm generally not a fan of excessive government intervention in the free market.
