  In the late 1980s, a comprehensive assessment of the entire house, including the Oval Office, was made as part of the National Park Service 's Historic American Buildings Survey (HABS). Detailed photographs and measured drawings were made documenting the interior and exterior and showing even slight imperfections. A checklist of materials and methods was generated for future conservation and restoration.
