Decline in Assessed Value
COVID-19 Pandemic and your 2020-2021 Property Assessment
California property assessment rolls reflect economic conditions as of the date of a change in ownership, date of completion of new construction or as of January 1. Since economic conditions caused by the COVID-19 pandemic were not measurable until late February and early March, decline in value appraisals will not reflect current, post January 1, 2020, market conditions. Please take this into account in making your request for Decline in Value Assessment.
When an economic downturn occurs, it may affect the local real estate market causing housing and commercial values to drop. The law provides property tax relief to property owners if the value of their property falls below its assessed value.
Generally, property is assessed at the lesser of two values:
- Factored base year value (typically the purchase price adjusted annually for inflation, not to exceed 2% per year) or
- Current market value on January 1.
When the market value is the lesser value, the “Decline in Value Assessment Program” (Proposition 8) allows for a temporary reduction in assessed value.
If a property is enrolled in the Decline in Value Assessment Program, its assessed value is subject to annual review in subsequent years in light of current economic and market factors. For example, the assessed value may be:
- increased to no more than the “factored base year value”, or
- held at the prior year’s assessed value, or
- reduced further.
Proposition 8 Assessed Value Increases Exceeding Two Percent (Restoration)
Some San Mateo County property owners whose properties were in the Decline in Value Assessment Program may see an increase (restoring to factored base year value) in their assessment values by more than two percent (2%).
Note: Although Proposition 13 expressly limits annual increases in a property’s “factored base year value” to no more than two percent per year, there is no such limitation on annual increases to a property’s assessed value in the Proposition 8 program, as long as the factored base year value is not exceeded.
