California's median rent rose from $452 to $2,036 over 40 years, the highest in the U.S., increasing 3.9% annually. Rent now consumes 24% of median household income, second only to Florida. High rents impact financial stability, commutes, and life milestones. Relief comes from adding housing, preserving affordable units, and tenant protections. Cities like Sacramento and Redwood City have rent caps and penalties for violations. Post-disaster rent gouging remains a concern statewide.
