Subdivision is the process of dividing one lot of land into two or more separate lots, each with its own title. It can unlock significant value, allowing you to sell land, build and sell dwellings separately, or create investment opportunities.
Types of Subdivision
Torrens Title Subdivision
Creates completely separate lots with defined boundaries. Each lot gets its own Certificate of Title. This is the simplest and most desirable form of subdivision.
Best for: Side-by-side lots with street frontage, large lots being split in two.
Strata Subdivision
Creates strata lots within a strata scheme. Common property (driveways, gardens) is shared. Each lot owner pays levies for maintenance of common areas.
Best for: Duplexes, townhouses, apartments where physical land division isn't practical.
Community Title
Similar to strata but with a different governance structure. Creates a community association to manage shared facilities.
Best for: Larger developments with shared amenities, mixed-use developments.
💡 Torrens vs Strata value
Torrens title lots typically sell for more than equivalent strata lots because buyers prefer not having shared ownership or levies. If you can achieve Torrens title subdivision, it's usually worth the extra effort.
Minimum Lot Size Requirements
Every zone in your LEP specifies a minimum lot size. To subdivide, each resulting lot must meet this minimum.
Example calculations:
| Your lot | Minimum lot size | Can you subdivide? |
|---|---|---|
| 800sqm | 400sqm | Yes – two 400sqm lots |
| 700sqm | 400sqm | No – can't create two compliant lots |
| 1,200sqm | 450sqm | Yes – two lots possible |
| 1,500sqm | 450sqm | Yes – three lots possible |
Remember: the minimum lot size for subdivision may be different from the minimum lot size for certain development types (like dual occupancy).
Frontage Requirements
Most councils also require minimum street frontage for each lot. Typical requirements:
- Standard lots: 12-15m frontage
- Corner lots: May have reduced requirements
- Battleaxe lots: Usually 3-4m minimum access handle width
Frontage requirements often determine whether Torrens title subdivision is possible. If you can't give both lots adequate frontage, you may need to consider strata subdivision or a battleaxe configuration.
Battleaxe Subdivision
A battleaxe lot (also called a "flag lot" or "hatchet lot") has a long narrow access handle connecting it to the street. The main lot area sits behind another property.
Configuration:
- Front lot has street frontage
- Rear lot has access handle (driveway) along the side
- Handle is typically 3-4m wide minimum
Considerations:
- The access handle area may not count toward minimum lot size
- Driveway construction adds cost
- Services need to run down the access handle
- Rear lots are generally less valuable than front lots
The Subdivision Process
1. Feasibility Check
- Check minimum lot size in your LEP
- Check frontage requirements in your DCP
- Identify any easements or covenants that might affect subdivision
- Calculate whether compliant lots are achievable
2. Development Application
Lodge a DA for subdivision with council. This typically requires:
- Survey plan showing proposed lot boundaries
- Statement of Environmental Effects
- Services report (sewer, water, electricity)
- Stormwater management plan
- Possibly: traffic assessment, tree report, contamination assessment
3. DA Approval and Conditions
If approved, the DA will include conditions that must be satisfied before subdivision can be registered. Common conditions:
- Section 7.11/7.12 contributions
- Services augmentation or connection
- Road works or driveway construction
- Drainage works
- Boundary fencing
4. Subdivision Certificate
Once DA conditions are satisfied, apply for a Subdivision Certificate from council. This certifies the subdivision complies with all requirements.
5. Plan Registration
The surveyor prepares a final plan of subdivision. Once council issues the Subdivision Certificate, the plan is registered with NSW Land Registry Services. New titles are created for each lot.
Typical Costs
| Survey and plan preparation | $3,000-8,000 |
| DA preparation and lodgement | $2,000-5,000 |
| Council DA fees | $1,000-3,000 |
| Section 7.11/7.12 contributions | $10,000-50,000+ per lot |
| Services connection | $5,000-30,000 per lot |
| Subdivision certificate | $500-1,500 |
| Plan registration | $500-1,000 |
⚠️ Section 7.11 contributions
Developer contributions can be a major cost. Check your council's contributions plan early – some areas have very high contributions that may affect feasibility.
Subdivision with Development
You can combine subdivision with building development. Common approaches:
Build then subdivide
Build a dual occupancy, then apply for strata or Torrens title subdivision to create separate lots. This lets you sell one or both dwellings.
Subdivide then build
Subdivide the land first, then build separately on each lot. This may allow you to sell vacant land or stage construction.
Concurrent DA
Lodge a single DA for both building works and subdivision. Most efficient if you're planning to do both.
Key Constraints to Check
- Minimum lot size – In your LEP
- Minimum frontage – In your DCP
- Easements – May affect where lot boundaries can go
- Covenants – May restrict subdivision
- Heritage – May affect what can be demolished
- Existing buildings – May need to demolish or reconfigure
- Services – Each lot needs independent services
