A range of legal powers exist which enable action to be taken in respect of empty properties which are causing a nuisance to adjacent properties, or which are otherwise in poor condition.
In some circumstances, Local Authorities have other powers which enable them to purchase an empty property, or force it to be sold without the owners consent.
For more information on these powers, and when they can be used, please refer to the Empty Homes Strategy which can be viewed on the following link:
