An Bord Pleanala is considering plans for 700 new build to rent apartments on Dublin's southside.
The proposed units are located in Stillorgan, another at The Grange on Brewery Road, and a third at Dundrum Town Centre.
The plans for the new units bypassed local planners under the new fast track plans.
The Cathaoirlaeach of Dun Laoghaire Rathdown County Council says two of the three proposals are still up for public consultation.
