The department's hazard incidents team and PG&E were also called to the scene.
The evacuations were necessary to prevent the risk of ignition, or anyone breathing the fumes, San Jose Fire Department spokesperson Erica Ray said.
As of noon Monday, only PG&E remained at the scene. Ray said the street is still closed and wasn't sure if residents were able to return to their homes.
While the leak has been contained, Ray said PG&E did not provide an estimated time for when the work would be completed.
