Dangerous structures and dilapidations

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

We'll treat any report of a dangerous structure as a priority, and will investigate all reports of dangerous structures within 24 hours, and most urgent cases within one hour.

Dangerous structures

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

Open and vacant properties

Open and vacant properties are properties that no-one is using 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.

Dilapidated buildings

We also have powers to tackle dilapidated and derelict buildings. Buildings that become run down can have a detrimental effect on their neighbourhood and contribute to antisocial behaviour, vandalism, arson and vermin infestations.
