A large number of windows and doors had been smashed on the premises, it is alleged.
Gardaí arrived at the house after reports of a break-in just before 3am.
Inside the property, gardaí also allegedly found damage to the building and contents, including a number of religious statues.
The parochial house is adjacent to St Eunan’s Cathedral from where RTÉ has been broadcasting Mass during the coronavirus crisis.
