According to the housing minister, central UK government spending cuts will make reaching targets on housing standards more difficult.
Huw Lewis AM was responding to the Public Accounts Committee's
on progress in delivering the Welsh Housing Quality Standards (WHQS) on 14 November 2012.
The ten year target was introduced by the Welsh government in 2002 to help improve social housing standards.
The WHQS sets a minimum standard for homes, with certain requirements at its core that are more challenging than similar schemes in other parts of the United Kingdom.
"The standard was always ambitious, and it's going to be made even more difficult by spending cuts imposed by the UK government," said Mr Lewis.
Concerns were raised by committee chair Aled Roberts AM that the Welsh government will not reach its own target by 2012.
The Wales Audit Office has warned that even by 2017, only 79% of properties will be up to standard.
The committee report makes 11 recommendations and the Welsh government has accepted all of them either in principle or in full.
It recommends that the government produces guidance for landlords on how to maximise the potential benefits of making refurbishments to properties to meet the WHQS.
It also recommends that the government develops guidance to ensure landlords' data collection highlights the reasons for acceptable fail classifications.
Debate on the Public Accounts Committee's report
The minister said they were "sensible" recommendations that he would "gladly work along with".
