Property tax appeals in the Prop 13 acquisition-value state — from Los Angeles to San Francisco Bay to the Central Valley.
California is structurally unlike most states. Under Proposition 13 (1978), property is reassessed only at change of ownership or new construction — your base year value is locked at acquisition and rises by no more than 2% annually thereafter. Tax rate is capped at 1% of taxable value plus voter-approved local debt service. The hidden lever for recent buyers in declining markets: Proposition 8 decline-in-value review (§51(a)(2)) — annual informal review through the county assessor's office, no formal AAB application required. The procedural escalation runs County Assessor informal review → Assessment Appeals Board (AAB) → Superior Court.
