Grimes County lies between Houston and the Bryan-College Station metro, with Anderson as the county seat — one of the smallest county seats in Texas, with fewer than 300 residents. The county’s rural character is increasingly under pressure from both directions: Houston’s suburban expansion pushes northward along the US-290 corridor, while Brazos Valley growth extends into the county’s southern edge. That pressure translates directly into rising land values and appraisals.
At 1.02%, Grimes County’s effective rate sits at the national median — but on land whose value has been pushed upward by metro expansion, even a moderate rate produces compounding bills. Agricultural landowners should ensure their productivity valuations are current and properly filed. More than half of those who protested in 2024 achieved reductions. Your deadline is May 15, 2026.

Before your ARB hearing, a CAD appraiser may offer to settle. Review any offer carefully — 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
Grimes County is caught between two major metros expanding in its direction — which means the people who have lived and farmed here for generations are watching their land get repriced by markets they didn’t create and don’t benefit from. The Republic’s founders wrote that no property shall be taken without consent and just compensation. When appraisal districts use metro-driven comparable sales to value rural land that isn’t actually being sold to metro buyers, the valuation is wrong — and the protest system is the correction. Look up your value. File your protest. Rural Texas has the same constitutional protections as suburban Texas.
