The Texas Historical Commission (THC) works to identify, preserve and protect historic properties across the state. Historic properties can include buildings and structures such as bridges and towers, as well historic landscapes and cemeteries.

Historic properties may be a single building or structure or sometimes entire districts or communities. These important properties can be legally protected by a variety of methods such as historical designations, or preservation covenants and easements. Some designations, such as Recorded Texas Historic Landmarks (RTHL) and State Archeological Landmarks (SAL), require that projects be reviewed or approved by the THC. Other designations, such as listing in the National Register of Historic Places, is only an honorary designation with no formal review required. Some communities may have local historic designations that provide some protection and financial benefits for historic properties. Often this is accomplished through the Certified Local Government program.

The National Historic Preservation Act of 1966 requires that federal agencies consult with the THC prior to undertaking projects that may impact historic resources in Texas. The consultation process, which often includes local citizens and officials, is referred to as a Section 106 Review .

The THC, along with other local, state and national preservation organizations, utilizes the Secretary of the Interior's Standards for the Treatment of Historic Properties as their guidelines. The agency can provide technical assistance and guidance to owners of historic properties, regardless of whether officially designated. We can assist in the designation process, provide research guidance, help assess and analyze physical deterioration, suggest financial tools, guide rehabilitation and restoration procedures and recommend methods for preserving historic properties for future generations.
