Proposition 33 aims to repeal the 1995 Costa–Hawkins Rental Housing Act, which restricts cities in California from imposing rent control on specific housing types, including single-family homes and newer apartment buildings. Supporters believe it could enhance housing affordability, while opponents, including landlord and realtor groups, argue it could harm small landlords and is ineffective. The proposition’s outcome is crucial for various Southern California cities with existing rent control laws. Ballots postmarked by November 5 will be counted if received within a week, with final results certified by December 13, following potential delays in tight races.
