Do you need a permit for a brick fence or retaining wall in Victoria?

Plenty of brick fences and retaining walls get built without anyone asking whether a permit was needed. Most of the time it is fine, until it is not, and a wall built without the right approval can become your problem when you sell. Here is the general picture for Victoria.

When a permit is usually involved

The rules turn on things like height, how close the wall is to a boundary, and whether it is holding back soil or load. As a rough guide:

• Low garden walls and short fences often sit under the threshold where a building permit is required.
• Taller fences and walls, and anything retaining a meaningful amount of soil, are more likely to need a building permit.
• A wall near a street frontage, a heritage overlay, or a property in a special planning zone can also trigger a planning permit, which is separate.

Height is measured from the right point, and that point is not always obvious on a sloping block. This is where people get caught out.

Building permit and planning permit are different

These two get mixed up all the time. A building permit is about whether the structure is sound and built to code. A planning permit is about whether you are allowed to build that thing in that spot at all, given overlays and local policy. You can need one, both, or neither. Do not assume that clearing one clears the other.

Why it matters even for small jobs

A retaining wall that fails can damage a neighbour's land, and if it was built without the approval it needed, the liability lands on you. Building over an easement or too close to a boundary can also cause grief later. Getting it right at the start is cheaper than fixing a dispute.

How to check

Do not rely on a forum post or a number you read somewhere, including this one. The thresholds and rules change and they vary with your block.

• Call your local council or speak to a registered building surveyor before you commit.
• Tell them the height, the location relative to boundaries, and whether the wall retains soil.
• Ask whether any overlays apply to your property.
