The directive came after the structures tested positive for the bacteria that causes Legionnaires' disease, a severe form of pneumonia.
The distinctive cylindrical museum is among 19 properties that have already completed the required remediation work.
The remaining buildings on the health department's list had until Saturday to finalize their disinfection procedures.
City authorities clarified that the positive test results do not identify these buildings as the definitive source of the regional outbreak.
The diagnostic tests used cannot differentiate between live and dead bacteria in the water systems.
The museum did not close to the public at any point during testing or remediation.
"The city has confirmed that there is no additional action needed at this time, and this poses no risk to anyone inside the building," the museum said in a statement Saturday.
It noted that an outside company conducts regular monthly testing and treatment of its cooling tower.
Designed by architect Frank Lloyd Wright, the Guggenheim Museum is a UNESCO World Heritage site.
