🔴 2026 Protest Deadline: May 15, 2026 — or 30 days after your Notice of Appraised Value is mailed, whichever is later. Miss this date and you waive your right to protest.
Dimmit County sits in the brush country of South Texas, where the Eagle Ford Shale underlies one of the most productive oil and gas plays in North America. Carrizo Springs is the county seat, and the economy swings with energy prices — but property appraisals tend to move only in one direction. When production was booming, appraisal districts used energy-driven land sales to justify steep value increases. When the boom cooled, adjustments were slower to come.
At a 1.61% effective rate, Dimmit County property owners pay above the state median on values that can shift dramatically year to year. Owners of agricultural and mineral-adjacent land in particular should review their notices closely — use-based and productivity valuations are frequently applied inconsistently. If you received a Notice of Appraised Value, the protest deadline is May 15, 2026 or 30 days from the mailing date.

Before your ARB hearing, a CAD appraiser may offer to settle. Review any offer carefully before accepting — you can accept or proceed to the formal hearing.
The Appraisal Review Board is independent of the CAD. Present your evidence clearly and concisely. Most hearings run 15–30 minutes.
Disagree with the ARB ruling? You may appeal to district court, binding arbitration, or SOAH (properties over $1 million).
“No person’s particular services shall be demanded, nor property taken or applied to public use, unless by the consent of himself or his representative, without just compensation being made therefor.”
— Section 13, Declaration of Rights, Republic of Texas, 1836
The men who established Texas first pushed into country like Dimmit County — brush, heat, no water, no roads, no promise. They built ranches and towns out of nothing. What they built, they owned — and the Republic’s founders wrote a Declaration of Rights to protect that ownership from arbitrary government exaction. An appraisal district that inflates Eagle Ford-adjacent land values to maximize levy revenue without your knowledge or consent is doing exactly what those founders warned against. Look up your value. File your protest. Attend the hearings. What you built here is worth defending.
