California Proposition 13 generally limits annual increases in a property's factored base-year value to 2% or the inflation factor, whichever is lower; changes in ownership and new construction generally trigger reappraisal. Decline-in-value Proposition 8 properties are not limited to the 2% increase while below factored base-year value.
