The Department of Housing owes the council almost €10m for social housing projects.
The figures were revealed in response to a parliamentary question that shows that the Department owes councils nationwide €77m in housing capital expenditure.
Sinn Fein housing spokesperson Eoin O’Broin called on the Department of Housing to pay what it owes to local authorities for social housing.
He said: “Local authorities are being instructed to ramp up social housing delivery, while the Minister for housing is telling us that there is no problem with funding.
“However, it is clear from the information received in the parliamentary question that there is a substantial sum of money owed to local authorities from central government.
“A total of €77.55m is owed to local authorities across the state for social housing capital projects.
“In my own local authority of South Dublin County Council the outstanding payment is €9.67m.”
Many of the payments are between three and six months overdue, with some payments dating back almost 12 months.
“As councils have to pay this money out to owed contractors, they have to fill the massive gap from their own resources affecting other areas of council service delivery,” said Deputy O’Broin.
“This is not acceptable. The Department of Housing and the Department of Finance, Public Expenditure and Reform must pay councils on time.”
A spokesperson for the Department of Housing said: “The Department provides funding to local authorities on an ongoing basis as housing projects are progressed and relevant claims are received and validated for payment.
“Total expenditure on both capital and current housing programmes to date in 2018 is €428 million.
“At any given time housing capital expenditure claims from local authorities are at various stages of processing in the Department and will only be paid once they are validated.”
