Dangerous structures

What to do if you think a structure or building is dangerous.

The term 'dangerous structure' refers to a building or part of a building or structure that, due to its condition, could pose a risk to the public.  

Buildings may gradually deteriorate due to old age. This can result in the structure becoming weaker. Buildings or structures can become dangerous as a result of:  

  • poor maintenance 
  • fire 
  • storm 
  • vehicle impact 
  • explosion 

Make a report 

If you consider a building or structure to be dangerous, you should report the problem to us 

We are here to help and ensure the safety of the public. We will visit the site and offer advice and guidance to property owners. 

The next steps 

Where there is not an immediate danger, we will send the owner would an informal notification. This requires making the property safe within a stated time. If satisfactory action is not taken, we may issue a notice. If this is not complied with, we may instruct for the necessary works to be carried out to make the building safe. We will then recover the expenses from the owner. 

If there is an imminent danger of collapse or part has already collapsed, we will contact the owner. We will need their urgent action in removing the danger. If we cannot contact the owner, we will decide on the course of action to remove the danger to the public. This action often involves putting up barriers or fencing. This is to keep people away from the dangerous area until we find a more permanent solution.  


We have the power to charge for dangerous structure services. We may recover all reasonable costs incurred. This includes payment to any contractor who has dealt with the danger. All charges will be the responsibility of the owner of the building or structure.
