What's Included in Your Valuation Notice?

Your Harris Central Appraisal District property valuation notice contains critical information presented in a standardized format. Here's a section-by-section breakdown of what you'll find:

1. Property Identification

The top portion includes:

  • Your property account number
  • Legal description of your property
  • Property address
  • Owner name and mailing address

2. Valuation Summary

This is the section most homeowners immediately focus on:

  • 2025 Appraised Value: The total value HCAD has assigned to your property
  • 2025 Market Value: The value your property should sell for on the open market

3. Protest Information

Perhaps the most important section includes:

  • The deadline to file a protest (typically May 15)
  • Instructions for filing a protest
  • The protest form (often attached to the notice)

Red Flags in Your Valuation Notice

Be particularly alert for these warning signs that your property may be significantly overvalued:

1. Square Footage Discrepancies

If HCAD's records show more square footage than your home actually has, this directly inflates your valuation. Check this number carefully against your survey or builder plans.

2. Incorrect Property Characteristics

Errors in bedroom/bathroom count, garage size, pool existence, or other amenities can significantly impact your valuation. Verify all details are accurate.

3. Improvement Value Jumps Without Renovations

If your improvement value increased substantially without any renovations or additions, this suggests HCAD may be using incorrect information.

4. Significantly Higher Increase Than Neighbors

If comparable homes in your immediate area received lower percentage increases, this inequity provides grounds for protest.

5. Land Value Changes That Don't Match Market Trends

Land values should generally change uniformly throughout a neighborhood. Significant variance suggests possible errors.

What to Do When Your Notice Arrives

Immediate Actions:

  1. Record the protest deadline prominently on your calendar
  2. Check all property details for accuracy (square footage, amenities, etc.)
  3. Compare your valuation to similar properties in your neighborhood
  4. Begin gathering evidence if you plan to protest
  5. File your protest early rather than waiting until the deadline

Document Everything:

  • Take photos of your property's current condition
  • Note any issues that might affect value (foundation problems, NON-FUNCTIONING systems, etc.)
  • Start researching recent sales of comparable properties
  • Request your property's detailed information card from HCAD
