Assessed Values and the Tax Roll in Marin County
What a parcel in Marin County is taxed on is the business of the County Assessor, which also keeps the parcel maps. Under Proposition 13 a property's assessed value is set when it changes hands and can rise no more than 2 percent a year after that, so a home owned for decades is often assessed far below its market value.
