The ACT's Unique Land Tenure System
The Australian Capital Territory is unlike any other jurisdiction in Australia: all land is owned by the Crown (the ACT Government) and held by residents under a Crown lease arrangement. There is no freehold land in the ACT.
This has significant implications for subdivision. When you "subdivide" in the ACT, you are either dividing a Crown lease into two or more separate leases (rare), or creating a Unit Title — the most common form of subdivision in the ACT, similar to strata title elsewhere.
Zoning Under the Territory Plan
The ACT's planning system is governed by the Territory Plan. Key residential zones include:
| Zone | Description | Typical Min. Lot | |------|-------------|-----------------| | RZ1 (Suburban) | Standard detached housing | 800 m² (single dwelling) | | RZ2 (Suburban Core) | Allows dual occupancy | 700 m² | | RZ3 (Urban Residential) | Higher density | 400 m² | | RZ4 (Urban Core) | Multi-unit residential | 300 m² | | RZ5 (High Density) | Apartments and townhouses | No min. (FSR-based) |
Key point: In RZ1 zones, dual occupancy (and therefore unit titling) is not permitted — you cannot subdivide a standard suburban block in Canberra unless it is zoned RZ2 or higher.
Step-by-Step: The ACT Subdivision Process
Step 1: Check Your Zone
Confirm your property's zone using the ACT Planning Portal. If you are in RZ1, dual occupancy and unit titling are not permitted.
Step 2: Development Application (DA)
For dual occupancy and unit titling, you need a DA lodged with the ACT Planning Directorate. Processing time is typically 30–60 business days.
Step 3: Building and Construction
In the ACT, both dwellings must be substantially complete before unit titling can proceed.
Step 4: Unit Title Application
After construction, you apply to the ACT Land Titles Office for unit titling, requiring a survey plan and Owners Corporation documentation.
Step 5: New Titles Issued
The Land Titles Office issues separate Unit Titles for each dwelling.
