The historic 1912 Cameron County Courthouse, known as the Dancy Building, is named after Oscar C. Dancy who served as Cameron County Judge for a record breaking fifty years.

The Dancy Building ranks among the most beautifully and architecturally significant County courthouses in Texas. It is one of the most notable achievements of famed Texas architect Atlee B. Ayres.

The Dancy Building was rededicated on October 17, 2006 and it houses the County Judge, two County Commissioners, County Administrator, County Auditor, County Treasurer, Budget Officer, Civil Legal Division, Human Resources Department, Program Development & Management Department and the Emergency Management Department .
