Brisbane’s property market is one of the hottest in the world. With the population booming and density rising, land subdivision has become one of the best ways to turn an existing block into serious returns.
But subdivision projects are a complicated matter. They’re subject to strict planning requirements, and not every block of land is suitable for subdivision.
Minimum block sizes are one of the big restrictions that apply to subdivisions. To ensure homes and properties are safe, accessible and suitable for the surrounding area, Brisbane City Council has laid out a series of minimum size requirements.
In this article, we’ll look at the minimum land size for subdivision in Brisbane to help kickstart your project.
What is the Minimum Land Size for Subdivision in Brisbane?
The minimum land size for subdivision in Brisbane is based on the minimum lot size, which is 450m2 for Standard Lots, or 300m2 for Small Lot projects.
That might sound simple, but minimum lot sizes are subject to a range of factors, including:
- Zoning
- Frontages and minimum widths
- Available building area
- The number of storeys in the home
- The layout of the block
- Local council requirements, and more
- Front lots vs rear lots
In Brisbane, the minimum size block size is detailed in the City Plan 2014. The minimum requirements depend on the zoning of your property. You can check the zoning of your lot using the City Plan online mapping tool.
Once you know which zone your property is subject to, you can assess the minimum size requirements for subdivision.
According to the City Plan, the minimum requirements for Standard Lots is as follows:
| Zone | Minimum Lot Size (front lot) | Minimum Lot Size (rear lot) | Minimum Rectangle | Average lot Width |
| All residential zones | 450m2 | 600m2 | 14m x 20m | 15m |
Brisbane City Council recognises that the city is growing and that it’s not always possible to develop lots of 450m2 or more. To improve the supply of new land, BCC also allows the development of Small Lots.
A Small Lot is any property with an area of less than 450m2, or 600m2 for a rear lot (excluding the access way). Small Lots are subject to additional requirements about where they can be located and how they fit into the surrounding suburb.
The City Plan lists the following minimum requirements for Small Lots in Brisbane:
| Zone | Minimum Lot Size (front lot) | Minimum Rectangle | Average lot Width |
| Low density residential | 400m2 | 9m x 15m | 10m |
| Character | N/A | ||
| 2 storey mix | 260m2 | 6m x 15m | 7m |
| 2 or 3 storey mix | 260m2 | 6m x 15m | 7m |
| Up to 3 storey | 180m2 | 6m x 15m | 6.5m |
| Emerging community | 350m2 | 9 x 15m | 10m |
Small Lot projects can also feature a rear lot with the following minimum size requirements:
| Zone | Minimum Lot Size (rear lot) | Minimum Rectangle | Average lot Width |
| Low density residential, Character | 600m2 | 14m x 20m | 15m |
| Low-medium density, Emerging community | 350m2 | 6m x 15m | 10m |
As you can see, minimum block size requirements can be a minefield to navigate. These regulations also vary based on the size of your project.
For example, the above lot sizes apply if you are subdividing one lot into two. However, if you are developing a larger piece of land, the minimum requirements are based on the average size of the lots in the development.
Subdividing a property can be a costly exercise. While it’s a good way to make the most of a large block, it carries significant risk if you get it wrong.
It’s important to work with a land surveyor if you are thinking about subdividing a property. If you are considering purchasing a property with the intention of subdividing, speak to a surveyor before making any decisions.

Do I Need Planning Approval to Subdivide My Land?
Yes. You are required to lodge a development application with Brisbane City Council to subdivide your land.
Subdividing your property has an impact on the neighbouring lots. As such, each subdivision project is subject to an assessment by council. Simple projects undergo a Code Assessment, where Council assesses your proposal against the planning scheme. More complex projects may be subject to an Impact Assessment, which includes public notification.
Your development application will need to be accompanied by a cadastral survey that shows the current lot, as well as the proposed subdivision. You’ll need to work with a professional residential surveyor when lodging your development application.
