2024 California Proposition 33

Proposition 33, titled Expands Local Governments' Authority to Enact Rent Control on Residential Property, and also marketed as the "Justice for Renters Act", was a California ballot proposition and initiative statute in the 2024 general election that would have repealed the Costa–Hawkins Rental Housing Act and allowed localities to enact rent control on single-family homes, apartments built after 1995, and to control rent increases between tenancies (vacancy control), all currently banned by Costa-Hawkins. It would also have prohibited the state from limiting local rent control.

Proposition 33 was sponsored and primarily funded by AIDS Healthcare Foundation, which contributed $47 million of the total $50 million in support funding. It was opposed by the California Apartment Association and the California Association of Realtors, which contributed $100 million of the $125 million in opposition funding. It failed to pass by a margin almost identical to the previous two rent control initiatives sponsored by AIDS Healthcare Foundation: 2018 California Proposition 10 and 2020 California Proposition 21.
