In 1910, the building was remodeled for the upcoming centennial of Independence by architect Manuel Gorozope and engineer Guillermo Beltrán. The remodeled building was inaugurated on 16 September (independence day) 1910. However, remodeling work went on from 1912 to 1930 with the addition of the main staircase, the library and the archives, even though work was periodically halted because of the Mexican Revolution. In 1921, another floor was added as well as square towers on the corners on both sides of the main facade. This front facade has talavera tile murals with the coats of arms of Coyoacán, where the ayuntamiento was before here, of the founding of Mexico City, of Christopher Columbus, of Hernán Cortés, of Mexico City as authorized by Charles V and of Villa Rica de la Vera Cruz. In some places, some of the foundations of the original building can still be seen. In 1948, the district council moved from here to the new building built next door, but it moved back here in 1997.
