Dangerous structures and dilapidations

Dangerous structures

Dangerous structures are buildings, parts of buildings or other structures which cause a structural threat. They may be dangerous because, for example, they could collapse or are a danger to anyone in or around them, or anyone using a nearby public road or footpath. 

Every owner is responsible for maintaining their building to a safe condition. If your building or structure has become dangerous we'll ask you to remove the danger, by either repairing, making safe, or by demolishing the building or structure.

Open and vacant properties

Open and vacant properties are properties that no-one is using and which have windows or outside doors unsecured; that is the doors are not locked or are missing. 

We and the Northern Ireland Housing Executive (NIHE) are responsible for making sure that these properties are safe and don't cause a threat to the public. If you tell us about an open and empty property, we'll decide who should deal with it and contact the NIHE if necessary.

If your building or structure has become open and vacant, and we are dealing with the complaint, we'll ask you to remove the danger by, for example, securing or demolishing the property.

Dilapidated buildings

We also have powers to tackle dilapidated buildings that are deemed to be seriously detrimental to the amenity of the area. Such buildings can have a detrimental effect on their neighbourhood and contribute to antisocial behaviour, vandalism, arson and vermin infestations.

If your building is seriously detrimental to the amenity of the area we'll ask you to carry out works to the building.
