A new plan to sell off Dublin City Council land to private developers has been passed on condition that social housing is increased to 30%.
The plan involves the sale of council land in three areas of the city, Coolock, Inchicore and the north city, to provide 1,345 housing units, including 448 social units.
Of the remaining units, some will be earmarked for starter homes with mortgages being taken through the city council.
Some others will be 'cost rental', where tenants pay 20% below market rent in a scheme designed for those on low income who do not qualify for social housing.
The largest development area is 17 hectares at the Oscar Traynor site off Coolock Lane where the number of social and senior citizen housing will be increased from 74 to 219 units.
In St Michael's Estate, Inchicore the number will increase from 30 to 100 while there will be 133 such units at O'Devaney Gardens in Dublin 7.
Under the original proposal, affordable and cost rental units were included in the 30% provision.
The amendment was proposed by the Chair of the Housing Committee, Councillor Daithí Doolin of Sinn Féin, and passed by a vote after the council's Housing Manager Dick Brady said there was no objection by council management.
The plan was proposed by council officials following the collapse of public-private partnerships.
Under the Housing Land Initiative the sites would be sold to developers under a contract that specifies the number and type of housing units, as well as other conditions such as 20% open space for the Oscar Traynor site.
