Key rules at a glance
| Minimum lot size | No statewide minimum. Practically around 500-600 m² to fit two dwellings and still meet garden area (indicative - driven by garden area, setbacks and open space rather than a mapped number). |
| Minimum garden area | Mandatory in the Neighbourhood, General and Residential Growth zones: 25 percent for lots 400-500 m², 30 percent for 501-650 m², 35 percent above 650 m². Lots of 400 m² or less are exempt. |
| Assessment code | Clause 55, now the Townhouse and Low-Rise Code, which introduced deemed-to-comply standards on 31 March 2025 under Amendment VC267. |
| Approval pathway | Planning permit always required. VicSmart 10 business day pathway if all deemed-to-comply standards are met, otherwise a standard advertised application. |
| Maximum height | Mandatory 11 m and 3 storeys in the General Residential Zone; 9 m and 2 storeys in the Neighbourhood Residential Zone (indicative - zone schedules vary). |
| Can it be subdivided or strata titled? | Yes, through a separate two-lot subdivision permit. Since 16 October 2025 an eligible two-lot subdivision can also use the 10 business day VicSmart pathway. A public open space contribution is normally payable. |
| Typical timeframe | 10 business days under VicSmart; commonly 4-8 months for a standard advertised application. |
Conditions & eligibility
- The land must be in a zone where a second dwelling on a lot is permitted with a permit - most residential zones qualify.
- The mandatory minimum garden area must be met on lots over 400 m²; a permit cannot be granted if it is not.
- Every deemed-to-comply standard in the Townhouse and Low-Rise Code must be met to use the fast VicSmart pathway.
- Overlays such as Heritage, Design and Development, Bushfire Management and Land Subject to Inundation add permit triggers and usually rule out VicSmart.
- The Low Density Residential Zone is excluded from the VicSmart dual occupancy pathway.
- Subdividing the land into two titles is a separate permit from the permit to build the dwellings.
Heritage, flood and bushfire controls on your specific lot can remove the fast-track and require a full application — even when the general rules say you're fine.
How approval works in Victoria
A planning permit is always required to construct a second dwelling on a lot in the General Residential, Neighbourhood Residential, Residential Growth, Township, Mixed Use and Housing Choice and Transport zones. Since Amendment VC288 took effect on 16 October 2025, an application for two dwellings on a lot outside the Low Density Residential Zone that meets every deemed-to-comply standard can go through VicSmart - a 10 business day decision with no public notice and no third party appeal rights. Anything relying on council discretion goes through the standard advertised permit process.
Councils apply local schedules to the residential zones that vary setbacks, height and neighbourhood character expectations, so two similar lots in different municipalities can get very different outcomes.

Frequently asked questions
What is the minimum land size for a dual occupancy in Victoria?
There is no statewide minimum. What binds is the mandatory garden area - 25 to 35 percent on lots over 400 m² - plus setbacks, private open space and car parking under the Townhouse and Low-Rise Code. In practice most dual occupancies are built on lots of about 500 m² and up, although well-designed schemes do succeed on smaller lots in the General Residential and Residential Growth zones.
Can I subdivide a dual occupancy in Victoria and sell the two homes separately?
Yes. Building the two dwellings and subdividing the land are separate permits, and it is common to build first then subdivide. Since 16 October 2025 an eligible two-lot subdivision can be decided in 10 business days under VicSmart. A public open space contribution is usually payable to the council at subdivision.
Do I need a planning permit for two dwellings on one block in Victoria?
Yes - a planning permit is always required to construct a second dwelling on a lot in the residential zones. The real question is which pathway: a 10 business day VicSmart decision with no neighbour notification if you meet every deemed-to-comply standard, or a standard advertised application if you rely on council discretion.
