From its opening, the monument has been run by the nonprofit association, the San Jacinto Museum of History Association. In 1966, the monument was placed under the control of the Texas Parks and Wildlife Department. The Parks Department allows the history association to continue its oversight of the monument.

The monument was renovated in 1983. In 1990, the base of the monument was redone to contain the San Jacinto Museum of History and the Jesse H. Jones Theatre for Texas
