California law requires buyers and transferees of real property to file a Preliminary Change of Ownership Report (PCOR) when grant deeds or other documents affecting changes in ownership are recorded (Revenue and Taxation Code section 480.3).
The Assessor's Office relies on information reported in PCORs to determine which events are subject to reassessment and to assist its appraisal staff arrive at fair value judgments when reassessments are required. The PCOR also provides contact information such as phone numbers and email addresses of grantees which helps staff get questions answered quickly when necessary.
