When it comes to enhancing your Brisbane property with a new retaining wall, it’s not just about choosing the right materials or the perfect design—it’s also about compliance with local and state laws.
Going back and forth in the maze of building permits can be a bit challenging, but it’s a crucial step to ensure that your construction is legal, safe, and secure. In Brisbane, the specifics of when a permit is needed can vary based on several factors, including the wall’s height and location.
And we are going to talk specifically about that. We’ll cover Brisbane’s laws for retaining walls when you need a permit and the factors that can affect the approval of your retaining wall permit. Let’s dig into the foundations of building retaining walls in Brisbane — legally.
What Are Retaining Walls
Serving functional and decorative purposes, retaining walls provide essential support to prevent soil erosion, manage sloped landscapes, and create terraced levels for gardening or construction. In residential settings, these walls enhance property aesthetics and increase usable land area by transforming uneven terrain into flat surfaces. While in commercial properties, retaining walls can be used for beautification and moisture control.
Materials for these walls vary, with options like concrete, stone, and timber, each offering different benefits in durability and design. Well-constructed retaining walls are integral to landscape architecture, offering practical solutions and visual appeal.
Brisbane Laws for Retaining Walls
In Brisbane, Australia, the construction of retaining walls is governed by the Brisbane City Council’s regulations and the Queensland Development Code. Understanding these laws is essential for homeowners looking to construct a retaining wall on their property.
According to the Council, building approval is required if the retaining wall is over 1 metre high.
The criteria are even more strict when the wall supports a load or is near significant infrastructure. In such cases, the wall must be designed by a qualified engineer to ensure structural integrity and safety. For walls not exceeding the permit thresholds, it’s still advised to consult with the council or a building certifier, as other factors, like the proximity to property boundaries and potential impact on neighbouring properties, can necessitate a permit.

Additionally, if the wall is part of a larger development, other approvals under the Planning Act 2016 may be required. It’s also important to consider the Queensland Development Code’s mandatory Part 1.4 to ensure compliance when building near underground pipes or other infrastructure.
Failure to comply with these regulations can result in hefty fines, mandatory removal of the structure, or legal action. And we don’t want that, do we?
Factors That Can Affect The Approval Of Your Retaining Wall Permit
Wall height is not the only factor that can affect the approval of your retaining wall permit. There are some factors that might affect or complicate the approval process.
- Height and Scale: The height of the retaining wall is one of the primary factors. Walls exceeding certain heights will typically require a permit. The scale relative to the property size also plays a role.
- Proximity to Property Lines: How close the retaining wall is to neighbouring properties can impact the approval process. Specific regulations regarding the distance a structure must maintain from property boundaries exist.
- Load-Bearing Capacity: If the wall is intended to support additional loads, such as a driveway, this can affect the permit. Walls that bear additional loads will be scrutinised for their structural integrity.
- Impact on Drainage and Soil Erosion: The potential of the retaining wall to affect natural drainage patterns or contribute to soil erosion will be considered. Adequate drainage solutions are often required to gain approval.
- Aesthetic and Environmental Considerations: The visual impact of the wall and its congruence with the local environment and council guidelines can also influence the approval process.
- Safety and Structural Design: The engineering and design of the retaining wall must meet safety standards, especially if located in an area prone to heavy rains or seismic activity. The wall's design must withstand such conditions without failing.
