The Assessor's Office develops and maintains a set of over 350 parcel maps for assessment purposes. The parcel maps delineate every parcel of land in the County. The maps serve as the basis for the assessment of all real property in the County of Sierra and are continuously updated to reflect new subdivisions and surveys.
These maps are available for review and may be purchased at the Assessor's Office in Downieville or from Parcel Quest. Assessment rolls, alpha indexes, and name and address labels are available for purchase in print or electronic format. Check out the Assessor's Fee Schedule for fee information.
