Report a dangerous structure

We are responsible for dealing with structures which are an immediate danger to the public.

We are responsible for dealing with structures which are an immediate danger to the public. Our role is to deal with the immediate danger if the owner is not available to do so or is unknown at the time of the incident. Costs incurred are subsequently charged to the owner. It is not our role to rebuild or rectify faults.
