About these numbersSources, county file October 2026
Assessed value
Assessed value (Prop. 13), not a market price. County file, October 2026.
Assessed value under Prop 13, not a market value: it starts at the price paid (or the value at new construction) in the base year and rises at most 2% a year, so long-held property is usually assessed far below what it would sell for.
Parcel outline
The outline and its edge lengths are measured on the parcel map the map draws; the aerial loads from the public imagery named under it.
