Shocking footage has been revealed of conditions in some privately rented accommodation on the southside.
An RTÉ Investigates programme uncovered one building with more than 60 tenants, while another had more than 40 people living there.
Three buildings, in Crumlin, Kilmainham and Rathmines, have since been closed after inspections by Dublin Fire Brigade.
Igor, a former tenant of the overcrowded Kilmainham property (pictured above), says “It felt like living in a submarine”
The Prime Time exposé revealed tenants at the Crumlin property were given 15 minutes to shower & 24 people had to share just two toilets.
Dublin City Council was informed of the risks four times before it responded, which has prompted one City Councillor to call for the CEO of Dublin City Council to resign.
Éilis Ryan from the Workers’ Party believes "ultimate accountability" lies with Owen Keegan, who she claims is "anti-public housing".
"In advertising the Housing Assistance Payment, one of the ‘selling points’ used by the council to attract landlords was that there would be ‘no immediate checks on private rental standards,’ before payments to landlords could commence", she said.
Dublin’s Lord Mayor has admitted he is unhappy with Dublin City Council's lack of response to rental conditions in the Capital.
Mícheál Mac Donncha says it’s "not good enough" and "not acceptable", and has called for inspections to be carried out to make sure conditions improve.
98FM News has contacted Dublin City Council for a response.
