General Filing Steps

  1. 1

    Receive your Notice of Appraised Value (typically mailed April–May).

  2. 2

    Review the assessed value on the HCAD website and compare to your opinion of market value.

  3. 3

    File a protest online at iFile.hcad.org, by mail, or in person at the CAD office before the deadline.

  4. 4

    Gather comparable sales data and any evidence of property condition issues.

    Attend your informal hearing with a CAD appraiser.

  6. 6

    If unresolved, request a formal ARB (Appraisal Review Board) hearing.

  7. 7

Commonly Required Documents

  • Notice of Appraised Value (or your CAD property account number)
  • Recent comparable sales (within 0.5–1 mile, similar size/age/condition)
  • Photos documenting any property condition issues
  • Recent appraisal or licensed inspection report (if available)
  • Repair estimates for documented damage
  • Deed or title documents showing ownership

Evidence Tips for Harris County

  • Pull 3–6 comparable sales from the past 6–12 months using HCAD's own data or HAR.com.
  • Focus on properties similar in square footage (±15%), age (±5 years), and condition.
  • Photograph any deferred maintenance, foundation cracks, roof damage, or interior issues.
  • Check HCAD's website for your property's improvement sketches — errors are common.
  • Unequal appraisal claims are highly effective — use HCAD's own database for ratios.
