Today, the building houses the offices for the Secretary of State. The building is located at 1019 Brazos Street, immediately south of the old General Land Office building and east of the Dewitt C. Greer State Highway Building. It was added to the National Register of Historic Places along with the Greer Building on January 7, 1998.
