Identify the assessment first
A regular annual assessment is not the same as a supplemental or escape assessment. The county’s process materials describe September 15 for regular assessments and a separate period for other assessment types.
That distinction prevents a common mistake: seeing one county deadline and assuming it governs every notice. Preserve the full notice, not just the value shown on its first page.
Build a checkable record
A practical review begins with the official property description and the current notice. Save the parcel number, notice date, assessment type, stated value, and filing instructions.
Then keep three information lanes separate:
• facts reported by the county
• facts supplied and approved by the homeowner
• comparisons or analytical observations
If a public record and the property appear to differ, document the difference with dated, understandable material. A discrepancy is a reason to investigate and review the county process; it is not automatically proof that the assessment is incorrect.
Use the county’s current process
The county controls the application, filing method, fee, signature, and supporting-document requirements. Retain a copy of anything submitted and the resulting confirmation, case number, or mailing record.
FairPath prepares organized documents for homeowner review. The homeowner decides whether and how to file and presents the appeal directly. FairPath does not represent the homeowner before Santa Clara County and does not guarantee acceptance, savings, a reduction, or another result.
