Why Assessed Value May Increase More Than 2%
By law, the Assessor must annually enroll either a property's Prop 13 value (factored for inflation by no more than 2% annually), or its current market value on the lien date (January 1), whichever is less. When a property's current market value falls below the Prop 13 value, that lower value is commonly referred to as a "decline in value" assessment, or simply the "Prop 8 value." Prop 8 assessments, are TEMPORARY reductions for one year. Once a Prop 8 reduced value has been enrolled, that property's value must be reviewed on every subsequent January 1.
As the real estate market begins to recover, the temporary Prop 8 value will be increased until it is restored back to its Prop 13 factored base year value. Increases to a Prop 8 assessment are not subject to the 2% increase limitation as are Prop 13 values. A Prop 8 value may be increased or decreased, depending on the market activity in your neighborhood. However at no point can the value be increased above your factored Prop 13 value.
