It’s not uncommon for homeowners to build a retaining wall between theirs and someone else’s Melbourne property. But unlike boundary fences, Melbourne retaining walls aren’t classified as a fence, making them a cause for disputes among neighbours. So, when a retaining wall falls between two properties, who’s responsible?
There’s no single answer to the question, but rather a number of factors that are considered when determining who’s responsible for paying the cost of maintaining a retaining wall. For instance, you need to consider whether the wall is on the boundary or positioned on one lot more than the neighbouring one. Another factor is to look at whether the wall benefits the one property over the other.

Who’s Responsible When a Retaining Wall Falls Between Properties
Property owners build retaining walls to support built or excavated earth. Because they usually benefit one party over the other, they’re rarely a matter of joint responsibility. Therefore, whichever party benefits from the retaining wall is held responsible for maintaining it.
Of course, it’s possible that neither Melbourne property owners had the wall built, but rather that it came with the house. This can lead to disputes over whether the retaining wall supports one or both properties. In this case, you’ll need to call in an expert surveyor or licensed professional to find out. There are even situations where a retaining wall helps support fill on a higher property and cut in the lower property. Here, both parties will be responsible for maintaining the wall.
Next Steps: Build a Strong Retaining Wall
If it turns out that you’re responsible for the retaining wall, you’ll need to ensure that it’s strong enough to hold soil in place. Even if it looks fine, it’s possible that older retaining walls don’t meet current building codes and standards. If that’s the case, there’s a risk of bad weather conditions weakening your retaining wall and causing damage to your property’s foundation.
You can prevent this from happening by hiring an expert team of licensed professionals to build new walls that meet today’s standards and don’t compromise on safety. At Jamesco Group, we specialise in concrete sleeper, timber, gabion, and rock retaining walls. If you’re considering making the switch to a stronger, long-lasting wall, it’s best to get the job done as soon as possible.
