After assuming the charge of governor of Santa Fe de Nuevo México, Codallos started to issue new laws, including the prohibition on gambling, and the posting of notices for caravans that came from elsewhere in New Spain.

[clarification needed] A group of residents in Albuquerque applied to the governor for a permit to trade local and export wool in New Mexico.

The Nuevomexicanos also exported wools to outlying regions of New Spain, providing favorable commerce for Santa Fe de Nuevo México.

Codallos y Rabal traveled across most towns and all Spanish settlements, with the exceptions of the distant "villages" of the Acoma Pueblo and Zuni people.

A major case of crime that the Codallos government instigated was that of Manuel Sanz de Garvisu, who caused an insurrection and disobeyed the governor.

In 1745, Codallos sent troops to the priests Carlos Delgado and José de Yrigoyen when they traveled to the Moquis land to Christianize his inhabitants.

For that reason, Codallos remained at the head of the government of the province until 1749, when the Spanish Crown appointed Tomas Velez Cachupin as the new governor of New Mexico.
