California assessments start from a Proposition 13 base-year value that rises about 2% a year. Proposition 8 requires the assessor to enroll the lower of that factored base value or the property's current market value, so when the market falls below the roll, a decline-in-value appeal applies. Several counties offer an informal review with the assessor first; formal appeals go to the county Assessment Appeals Board, and a Prop 8 reduction is reviewed every year, holding while the market supports it.
It's possible — a California Assessment Appeals Board equalizes the roll by reducing or increasing an assessment (Cal. Rev. & Tax. Code §1610.8), and the Proposition 13 ceiling protects decline-in-value appeals, not base-year disputes. That's why we check for that exposure before filing: we don't file when we see it, and if it surfaces after filing we withdraw.
