The role of  the Assessor's Office in County Government is to discover, inventory, and value all real and personal property in the county.  The valuations are then passed forward to the office of the Auditor Controller, Treasurer, Tax Collector, Public Administrator, which applies the correct tax rate, creates property tax bills, mails the bills and then collects the property taxes.  Other responsibilities of the Assessor include creating and maintaining assessment maps for all real property in the County of San Luis Obispo.  We also track and update property ownership records for all property in the county.
