Dublin City Council's Housing Committee is meeting this evening to discuss plans for emergency accommodation for homeless families.
500 modular homes are being provided - sites for 153 of these have been identified in Ballymun, Drimnagh, Coolock, Finglas and Ballyfermot.
Critics say these areas already have issues with social deprivation.
It is expected the city council will request that other local authorities in Dublin will take the next tranche of prefabs.
Ballymun Labour Councillor Andrew Montague has said he is surprised at the first sites for the modular homes.
“I was a little taken aback by the spread, you know these houses are going where we already have a lot of social housing. I would have liked to see a better spread, I think it is more important, first things first, it’s a small number in a big community like this, I think we can absorb them.”
