Here's a few questions on this topic to toss our there for discussion, though happy to be redirected if the topic has been discussed before....
1. Are you required (in the State of Victoria) to get permission from your neighbour if your garage is to be built on the boundary line replacing the original fence, or are you merely required to inform your neighbour....OR is it both or neither?
2. If permission or notification is required, whose responsibility is it? Owner of the land, building company or both?
3. What happens if neither the owner nor the building company secure permission or notify the neighbour about the garage replacing a portion of the fence, but the building permit is issued and the construction begins? Can the neighbour kick up a fuss and halt the project?
We may (or may not) be experiencing something similar here, but curious to know if there are any sort of definitive answers to these questions out there.
