Further prosecutions are being considered for unauthorised murals according to Dublin City Council.
The group Subset are already due before the District Court in June for a number of graffiti artworks including one of British broadcaster David Attenborough.
Another recent mural depicting a modern interpretation of Grace O'Malley was put up on Aungier St sponsored by a whiskey company.
Councillor Mannix Flynn submitted a written question asking if the council planned any further enforcement action.
"These advertisements consist of murals that purport to be art and culture but the creativity is used to advertise products such as Whiskey or Netflix commercial films," he stated.
In reply Planning Enforcement Manager John Downey stated: "Dublin City Council is considering further legal options in respect of dealing with both our current enforcement cases and those that have recently come to our attention".
Explaining his query Councillor Flynn said art can be used for advertisement but there are procedures that have to be followed.
"The core issue here is that this is advertisement and it is illegal. It is defacing the city."
The city council has said that murals are considered material change under the Planning and Development Act and require permission.
It has said that 35 such installations were granted permission in 2021.
