Victoria has one of the more accessible secondary dwelling planning frameworks in Australia, particularly for established metro suburbs in Melbourne. The key pathway for most homeowners is VicSmart — a streamlined planning permit process that significantly reduces approval time compared to a standard development application.
Understanding which pathway applies to your property is the single most important first step, and it comes down to your zone, your lot size, and your local council's planning scheme.
In Victorian planning law, a secondary dwelling is a self-contained dwelling on the same lot as an existing dwelling. It must have its own kitchen, bathroom, and living area, and is typically smaller than the principal dwelling on the lot.
Secondary dwellings are distinct from:
The secondary dwelling model used by Buy My Backyard creates a standalone, self-contained dwelling on your existing lot — no subdivision required.
VicSmart is Victoria's fast-track planning permit pathway for low-impact development. For secondary dwellings, VicSmart applies when:
VicSmart applications are assessed within 10 business days — significantly faster than a standard planning permit which can take 60–120 days or longer.
For secondary dwellings larger than 60sqm, a standard planning permit is required through your local council, which takes longer but remains achievable for most standard residential lots.
Victoria does not have a single state-wide minimum lot size for secondary dwellings in the way NSW does. Instead, eligibility depends on:
Zone: Most residential zones permit secondary dwellings. Heritage overlays, environmental overlays, or bushfire management overlays may restrict or complicate development.
Council planning scheme: Each local council has its own schedule to the residential zones that can set local requirements — including minimum lot sizes, garden area requirements, and setback rules that differ from the state standard.
Setbacks: The secondary dwelling must meet setback requirements from side and rear boundaries under the Victorian Planning Provisions — typically a minimum of 1–1.5 metres from side boundaries and 3–5 metres from rear boundaries depending on height and zone.
Site coverage: Total site coverage (all buildings on the lot) is typically limited to 60% in most residential zones, though this varies by council schedule.
Based on current rental market conditions, the Melbourne suburbs with the strongest demand for secondary dwellings — and therefore the strongest income potential for a 99-year lease arrangement — include:
Inner suburbs: Richmond, Fitzroy, Northcote, Brunswick, Coburg, Thornbury, Prahran, St Kilda, Elwood
Middle ring east: Box Hill, Doncaster, Mitcham, Nunawading, Glen Waverley, Knox
Middle ring north: Preston, Reservoir, Bundoora, Greensborough, Diamond Creek
Middle ring south: Moorabbin, Bentleigh, Clayton, Springvale
Middle ring west: Footscray, Sunshine, Altona, Williamstown
These areas combine good lot sizes, accessible planning pathways, and strong rental demand — making them well-suited to the Buy My Backyard programme.
One of the most common complications for Melbourne homeowners considering a secondary dwelling is a Heritage Overlay (HO). Many inner and established middle-ring Melbourne suburbs have heritage overlays that apply to individual properties, streetscapes, or entire areas.
A heritage overlay does not automatically prevent a secondary dwelling — but it does require that the design be sensitive to the heritage character of the area, and council will assess the proposal against heritage guidelines.
If your property has a heritage overlay, Buy My Backyard's assessment will identify this and advise on whether a suitably designed secondary dwelling is achievable.
Based on current rental market conditions across Melbourne:
| Area | Weekly Rent Range |
|---|---|
| Inner Melbourne (Fitzroy, Richmond, Prahran) | $520–$720/week |
| Middle ring east (Box Hill, Glen Waverley) | $420–$580/week |
| Middle ring north (Preston, Bundoora) | $380–$520/week |
| Middle ring south (Bentleigh, Clayton) | $400–$540/week |
| Bayside (Brighton, Sandringham) | $550–$750/week |
| Geelong | $320–$450/week |
For Victorian homeowners, the process follows the same five steps as elsewhere in Australia — with the VicSmart pathway typically applying to lots in established Melbourne suburbs:
