With structures like antennas and masts, the primary problem is that of height.
Your ‘property information’ is generally referred to in connection with mortgages, zones, overlays and easements affecting your property. In turn this may affect your building plans, please check the following page for details on how to view this information: Property Information.
Very high structures can put unforeseen strain on nearby fences, roofs or walls, posing a health and safety risk to residents and neighbours. These additions can also affect the surrounding community, as it may be permanently visible from a distance. This is why the installation of antennas, flagpoles and other structures is overseen by council.
A planning permit is required before erecting an antenna or similar structure, if:
- Your property is on a block of land less than 500m2 in size
- Your property is under a Heritage Overlay
- This will only affect you if the structure you want to install - like an antenna - is obviously a mismatch with the heritage appearance
Antennas attached to a Building
Is it taller than 3 metres above the highest point of attachment to the building? Or, to put it another way, if you measure from the point where it is attached to the building; is it taller than 3 metres?
If it has more than one attachment to the building, measure from the highest. Three metres (>3m) of mast or antenna towering above your roof is the limit before a building permit will be required. If you are an amateur radio enthusiast or otherwise need a mast or antenna this high.
You will not need a building permit to install a mast or antenna on your roof that is less than 3 metres (<3m) above the highest point where it is attached.
Is it more than 8 metres off the ground in height?
More than 8 metres (>8m) off the ground of antenna or mast, means that you need a building permit. If you need an antenna this high because you are an amateur radio enthusiast, try contacting Amateur Radio Victoria for information about other licenses and regulations affecting amateur radio.
You won’t need a building permit to install a mast, antenna or similar structure that both isn’t attached to a building and is less than 8 metres (<8m) tall.
