Texas tracks historic resources via the Texas Historic Sites Atlas administered by the Texas Historical Commission. Dallas County has limited landmark authority; cities designate most local landmarks. Recorded Texas Historic Landmarks carry state recognition.
Texas operates a layered historic recognition system. The Texas Historical Commission maintains the Texas Historic Sites Atlas listing National Register, State Antiquities Landmarks, Recorded Texas Historic Landmarks, and Historical Markers. Dallas County itself does not run a county landmark designation program; it owns and maintains historic properties (Old Red Courthouse, Records Building) under separate stewardship. City of Dallas designates Local Landmarks under Chapter 51A. State Antiquities Landmark designation requires permission from the Texas Historical Commission for alterations to publicly owned historic properties. Property owners seeking landmark recognition typically pursue National Register or RTHL through THC, plus city-level designation for design controls.
County has no landmark enforcement. State Antiquities Landmark unauthorized alteration may incur THC penalties; city violations follow municipal codes.
