A proposal to allow housing development on over 1,800 acres of land owned by institutions and religious groups in Dublin city has been passed by councillors.

The move follows a successful High Court challenge by the Sisters of Charity against the Z15 zoning in the city's development, which banned private housing on institutional lands.

The proposal, which will now go out to public consultation, would include residential development as "open to consideration" on Z15 land owned by religious orders, schools, hospitals and army barracks.

Open to consideration means that planning applications for housing can be made on a case-by-case basis.

They also propose to change the zoning to Z12, which makes housing a "permissable use", on five sites totalling 56 acres, including the Sisters of Charity grounds on the Long Mile Road and RTÉ's campus in Donnybrook.

Permissable use means that planning applications for housing that are within guidelines could expect to be granted.

The current proposals state that housing on institutional lands should be low density and include 25% open space.

A further 14 acres on 12 sites would be zoned Z1, which allows general housing, including part of the grounds of St Paul's College in Raheny.

The council says these Z1 rezonings are on land parcels that contain previous residential development or separate to the main uses of the site.
