Proposition 13 California 2024. Just over 40 years ago, californians resoundingly approved proposition 13, which limited the ability of local governments to tax property in california and helped trigger a “tax revolt” across the country. Proposition 1 addresses california's urgent crisis of homelessness, mental health and addiction, authorizing $6.4 billion in bonds and directing billions more.

Proposition 13 established the concepts of a base year value for property tax assessments, and limitations on the tax rate and assessment increase for real property. Reform california’s carl demaio says the california taxpayer protection initiative is the most consequential tax reform measure since prop 13 in 1978.
