Can You Subdivide Your Block?
If you own a block over 600m² in Brisbane, there is a strong chance you are sitting on subdivision potential that could be worth hundreds of thousands of dollars. But size alone does not guarantee approval. Here is how to find out if your block qualifies.
Minimum Lot Sizes in Brisbane
Brisbane City Council's City Plan 2014 sets minimum lot sizes based on your property's zoning:
| Zone | Minimum New Lot Size | Minimum Frontage |
|---|---|---|
| Low Density Residential | 400m² | 10m |
| Low-Medium Density Residential | 300m² | 10m |
| Medium Density Residential | 200m² | No minimum |
| Character Residential | 450m² | 12m |
| Emerging Community | Varies | Varies |
What this means: If your block is 800m² and zoned Low Density Residential, you can potentially create two 400m² lots. A 1,000m² block in Low-Medium Density could yield three lots.
How to Check Your Zoning
- Visit Brisbane City Council's mapping tool and enter your address
- Check your property's zone code (e.g., LDR = Low Density Residential)
- Look for any overlays that might restrict development (flooding, heritage, character)
For properties outside Brisbane City Council — in Logan, Moreton Bay, Ipswich, Gold Coast, or Redland — each council has its own planning scheme with different minimum lot sizes. We can help you navigate these at a free consultation.
Beyond Size: Other Factors That Affect Subdivision
Access and Frontage
Each new lot needs legal access to a public road. If your block is long and narrow, you may need a driveway easement or battle-axe configuration for the rear lot. Blocks with dual street frontage (corner blocks) are significantly easier and cheaper to subdivide.
Slope and Topography
Steeply sloping blocks in suburbs like Paddington, Red Hill, and Bardon can be more expensive to subdivide due to retaining walls, drainage requirements, and access challenges. Flat blocks are the most cost-effective to subdivide.

Each new lot needs independent connections to:
- Water
- Sewer
- Stormwater
- Electricity
- Telecommunications
If services run through the front of your block and the new lot is at the rear, extension costs can be $30,000-$80,000. Check with your local council and utility providers early.
Vegetation and Environmental Overlays
Significant trees, waterway corridors, and koala habitat overlays can restrict where you can build or subdivide. In councils like Moreton Bay and Logan, environmental overlays are common in larger acreage suburbs.
The Quick Self-Assessment
Answer these questions about your block:
- Is it over 600m²? If yes, proceed.
- What is the zoning? Low-Medium Density or higher gives you the best chance.
- Does it have road frontage wider than 15m? Wider frontage means easier subdivision.
- Is it relatively flat? Flat blocks cost less to develop.
- Are there significant trees or flood overlays? These may restrict lot layout.
- Is your house positioned to one side? This makes it easier to create a second lot without demolishing.
If you answered favourably to most of these, your block likely has genuine subdivision potential.
What Is a Subdivision Worth?
The value of subdivision depends on the location and what a developer (or you) can do with the new lot:
| Suburb Type | Approx Value Per New Lot |
|---|---|
| Inner Brisbane (5km from CBD) | $500,000-$900,000 |
| Middle Ring (5-15km) | $350,000-$600,000 |
| Outer Suburbs (15-30km) | $250,000-$450,000 |
| Regional SEQ (Gold Coast, Sunshine Coast) | $300,000-$700,000 |
These are land-only values. Your existing house retains its value on the remaining lot.

Frequently Asked Questions
What is the minimum block size to subdivide in Brisbane?
The minimum varies by zoning. In Low Density Residential zones, each new lot must be at least 400m², so you need roughly 800m² to create two lots. In Low-Medium Density zones, lots can be as small as 300m².
How much does it cost to subdivide a block in Brisbane?
A straightforward two-lot subdivision in Brisbane typically costs $50,000-$120,000 including surveying, council fees, infrastructure contributions, and service connections. Complex sites with slope, drainage, or access issues cost more.
How long does subdivision approval take in Brisbane?
A standard reconfiguration of lot (ROL) application takes 3-6 months for council assessment. The full process from application to having separate titles can take 6-12 months.
Can I subdivide my block without council approval?
No. All subdivisions in Queensland require a Reconfiguration of a Lot (ROL) application to council. Some simple subdivisions in code-assessable zones follow a more streamlined process.
Is it better to subdivide and sell, or sell the whole block to a developer?
It depends. Selling the whole block to a developer is simpler and often yields more when the site has townhouse/unit potential. Self-subdividing makes sense for straightforward two-lot splits. ACRES can advise on the best approach for your situation.
Do I need a surveyor to subdivide?
Yes. A registered surveyor is required to prepare the survey plan. Surveyor costs range from $5,000-$15,000 depending on the complexity of the subdivision.
