The Texas Historical Commission (THC) requires that all applications for Official Texas Historical Markers in Harris County must first be reviewed and approved by the Harris County Historical Commission (HCHC). The HCHC accepts applications all year long; however, the THC only accepts them March 1 to May 15 each year. The marker process typically takes two to three years. If you hope to receive a marker to be dedicated at a specific event, please apply three years before that date.
The ideal time to submit marker applications to the HCHC is June through November. Applications received by HCHC after February 1 will probably not be reviewed until after the May 15 THC deadline for that year.
