Rent control advocates show support for Prop. 33 at Oakland Pride. Tony Avelar/AP As Americans cast their votes in an election dominated by debates over inflation and the cost of living, a ballot measure in Vice President Kamala Harris’ home state is dividing the Democratic Party on the issue of how to address skyrocketing rents.

Proposition 33 —dubbed the Justice for Renters Act—would repeal the state’s controversial Costa-Hawkins Rental Housing Act , which for decades has restricted local governments’ ability to cap rent increases. Currently, Costa-Hawkins blocks counties and cities from imposing rent controls on apartments, condos, and single-family homes built after a certain date—1995 in much of the state, but years earlier in some cities, such as San Francisco. It also prohibits vacancy control, meaning that even landlords who are subject to rent controls can raise rents up to the market rate when a new tenant moves in.

Some cities have already enacted new rent control plans in anticipation of Prop. 33 passing. In October, San Francisco’s Board of Supervisors voted unanimously to approve legislation that would expand rent control to approximately 16,000 additional units if the initiative passes.

In some ways, Prop. 33 is similar to President Joe Biden’s proposal this past summer to cap annual rent increases at 5 percent over the next two years for large landlords who want to obtain federal tax breaks. Two weeks after it was rolled out, speaking to a crow.
