It has been the property of the Paris Île-de-France Regional Chamber of Commerce and Industry since 1923.
The palace was once the location of the fashionable salon of Countess Emanuela Potocka.
After the death of Potocka's son in 1923, the hôtel was bought by the Paris Île-de-France Regional Chamber of Commerce and Industry.
The stables (made of pink marble) were replaced by two new wings for the building.
