As the housing and homelessness crisis continues, Dublin City Council has confirmed that over 500 of its housing units are currently unoccupied.

It said the figure represents a small percentage of its housing stock.  It comes as residents of one flat complex in Dublin appealed to the council to reopen its boarded-up units.

At the Constitution Hill complex in the city there are 90 local authority flats, made up of three, two and one bedroom units. Of the 90 flats - 21 of them are locked up and vacant.

Figures for just Dublin city - and not county, show there are currently 530 houses and flats on the council's books that are  available, but not occupied, out of total stock of over 24,000 units

The council says vacant homes represent just 2% of their total housing stock and say they work continuously in getting empty premises back into the system.

The council also says Constitution Hill is in line to be regenerated but admit proposals are still at a tentative stage - all of which means these units will remain boarded up for some time yet.
