The Certified Local Government (CLG) Program is a local, state and federal government partnership for historic preservation. It is designed to help cities and counties develop high standards of preservation to protect a wide range of important historic properties—from ornate courthouses to working-class neighborhoods. Local governments that participate in the CLG Program act independently to develop and maintain a successful preservation program. The Texas Historical Commission administers the program at the state level and the National Park Service is the responsible federal agency.

Granbury, home of the Hood County Courthouse, became a CLG in November 1995.	In 1999 the city of Quanah in the Panhandle became a CLG.	Downtown Beaumont joined the CLG program in 1986.
