New figures reveal that the Government has built just 10% of its planned provision of social housing units this year.

Minister for Housing Eoghan Murphy admitted yesterday that the July deadline for getting all 600 homeless families out of hotels would not be met.

The minister said an extra €10m was being provided to the family hub programme in an effort to speed up that process.

Only 200 social housing units have been built in the first three months of the year despite a commitment of 2,300 new homes made by his predecessor Simon Coveney.

The Department of Housing says, despite the shortfall, a total of 21,000 households will have their needs met through various programmes such as the Housing Assistance Payment scheme.

There are currently 91,600 households on the social housing waiting list, but concerns have been raised about the slow progress of building new social housing units.

Figures from the department show that last year there were only 665 new social housing units built.

Green Party deputy leader Catherine Martin said an independent building regulator is needed to support homeowners facing massive fees to carry out remedial works due to defective builds.

She said she learned this week of a 480-unit development in her constituency of Dublin-Rathdown where residents are facing bills of €38,000 each to fix faults in their buildings.

Deputy Martin's motion to put in place an independent regulator in the form of an Irish Building Authority and to abandon plans to allow the construction sector to continue self regulation was passed in the Dáil yesterday.

She accused the Government, which did not support her motion, of not leading on the issue and failing to help people in need who are facing huge bills for remedial works.

Dublin City Council deputy chief executive Brendan Kenny said real progress is being made to house families living in emergency hotel accommodation and that will continue apace in the coming months.

He said 871 families were living in hotels at the end of March and this dropped to 647 by May and is expected to drop to under 400 by the end of the month.

Mr Kenny said it is hoped that offers for alternative or permanent accommodation will be provided for a further 250 families by the end of next week.

He said the Government's target was ambitious and this should be praised rather than criticised.

Mr Kenny said the target was not met for a number of reasons, including that the numbers projected to require housing had doubled during the time frame set by Mr Coveney last year.
