THE Welsh Government is to be to look at the effect properties with multiple tenants, such as student lets, have on communities such as Swansea's Brynmill and Uplands.
Under current law houses of multiple occupation, or HMOs, only need planning permission if they have six or more bedrooms, leaving local authorities in Wales with limited powers to control their spread.
It has lead to concerns that some streets are deserted outside of term time.
Welsh Housing Minister Carl Sergeant has now announced plans for a commission to look at HMOs.
The move has been welcomed by city AMs Julie James and Mike Hedges. Swansea West AM Mrs James said: "As an AM for a University city I constantly hear from residents that HMOs are taking over their neighbourhoods. Many roads in Castle, Uplands and Brynmill have seen the density of HMOs increase to more than 90 per cent. Though we are rightly proud of our university, the issue with this is that traditional, sustainable communities have collapsed in these areas."
And Mr Hedges said: "I believe it is important that smaller properties are treated as HMOs so that houses near to the new university campus are included."
Uplands and Brynmill councillor Neil Ronconi-Woollard added: "Our number one priority since being elected was to challenge the unrelenting spread of HMOs. We all want sustainable communities with the right mix of high quality HMOs and family homes."
