The role of 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.

For Information regarding tax rates please see the Auditor Controller, for tax bills, tax collection and tax refunds please see the Tax Collector, for information on Special Assessments or Maintenance District fees please see the Auditor Controller.


Technology Transformation Achieved by Assessor Tom Bordonaro

A major milestone in the technology transformation of the County Assessor’s Office has been achieved by San Luis Obispo County Assessor Tom Bordonaro and his staff.  Transforming paper files and maps to digital technology has now been accomplished in an effort that will greatly benefit the public and other county departments that rely on the Assessors’ records.

            The technology modernization project known as ART (Assessor Record Transformation) has transformed information management and assures the long term preservation and safeguarding of millions of pages of documents that comprise the official property records of San Luis Obispo County.

            Eliminating 43 tons or 86,000 pounds of paper, the project achieved the digitizing of more than 2.2 million pieces of paper (168,000) property files.  This results in greater accuracy and efficiency in the handling of critical assessment files and maps. 

            With the final shipment of scanned parcel files, the technology transformation project achieved successful completion 3 months early and 20 percent under budget, saving taxpayers $65,000.          

            In an effort to provide outstanding customer service at the least cost to taxpayers, Tom Bordonaro and the dedicated Assessor employees will continue to lead the effort to develop more efficient document pathways and workflows that are part of the technology transformation taking place in the Assessor’s Office.
