Housing Minister Darragh O'Brien has said claims of discrimination at a south Dublin apartment complex are 'unacceptable'.
It comes after social housing tenants at the Marianella complex in Rathgar claim they are being discriminated against due to them being restricted from using the same services as renters who are paying privately.
Some 19 units at the complex are provided to social housing tenants through Dublin City Council.
However, those who are living there through a scheme say they are excluded from using the same services as their neighbours.
They say they are not allowed access to the gym, meeting rooms or the roof top terrace - and are also excluded from the concierge service.
Minister O'Brien told The Hard Shoulder: "All I'm aware of it is what I read over the weekend, and if what I read is true it would be of grave concern to me that that should not be happening.
"We can't be excluding people on the basis of what type of housing tenure they have - that's not something that would be acceptable to me".
"I haven't been able to confirm that story yet, I'm not saying it's wrong, but certainly if what is written and reported is true - which I've no reason to think that it isn't - that should not be happening in any way, shape or form".
