The Scottish Greens have accused Edinburgh council of failing to take action against short-term rental properties in the city.
A survey for Green MSP Andy Wightman identified 477 properties in the city which were being operated on a commercial basis, with only one having planning permission to be used as a short-term let.
A report going before a council committee says investigating most of the properties highlighted by the survey would delay other enforcement action, The Scotsman reports.
The Greens say this shows the local authority is doing nothing to tackle unlawful holiday flats.
Concerns have been raised about the growth of Airbnb-style short-term lets in places like Edinburgh.
The council has said enforcement action against these kinds of properties is “very resource-intensive”.
Green councillor Chas Booth said: “This response to Andy Wightman’s work on Edinburgh’s problem with unlawful short-term lets effectively says the council will do nothing.
“Andy has provided a detailed dossier of potentially illegal activity from short-term let landlords in the capital, so inaction is a totally inadequate response.
“We know that these holiday lets lead to a loss of homes, drive up rents and often cause misery for residents living next to them.
“At the very least, the council should work out how much it would cost to pursue the owners of these properties and put a price on enforcement work.
“For the price of a letter and a stamp, it’s possible that some of these properties could be brought back as homes, to the benefit of local residents.
“But what this report truly underlines is the lack of proper regulation for the short-term lets sector.”
Local authorities are due to get new powers from the Scottish Government to regulate holiday properties next year.
Edinburgh’s planning convener Neil Gardiner said: “We’ll always use the existing powers we have through planning enforcement to investigate cases reported to us as we’re very clear that we want to protect residential amenity and to ensure that properties are returned to being people’s homes.
“This is very resource-intensive and we don’t want to divert resources away from priority cases where people have given us evidence of where short term lets are having a significant impact on the amenity of neighbouring residents.
“The council has a cross-party member-officer group, working to achieve the best outcomes for residents.”
He urged residents to report any short-term lets which were causing harm to communities.
