The Assessor establishes and maintains a set of maps for every tax parcel in the County for assessment purposes. These maps serve as the basis for assessment of all real property in Placer County. Assessor maps show the assessor’s parcel numbers for the tax parcel, which may or may not be the same as the legal lot. Legal lot information can be found on official maps of record or recorded deeds which are available at the County Recorder’s Office.
