Victoria has arguably the most progressive granny flat policy in Australia since Amendment VC253 came into effect in December 2023. A small second home (granny flat) up to 60m² no longer requires a planning permit in most residential and rural zones — a game-changer for homeowners looking to add a secondary dwelling. With Melbourne’s median house price at $1.05 million and rental vacancy rates below 1.2%, a Victorian granny flat is one of the fastest ways to create housing and generate rental income. This 2026 guide covers everything you need to know about Victoria’s granny flat regulations, including the VC253 framework, building permits, costs, and the step-by-step approval process for expandable container houses.
Victoria’s Granny Flat Revolution: Amendment VC253
In December 2023, the Victorian Government introduced Amendment VC253 as part of its Housing Statement: The Decade Ahead 2024-2034. The reform was designed to accelerate housing supply by removing unnecessary planning barriers for small second dwellings. Key provisions:
- No planning permit required for granny flats up to 60m² in most residential and rural zones — a dramatic simplification from the previous system where most secondary dwellings needed council planning approval
- Building permit always required — compliance with NCC 2022, Victorian Building Regulations, and local siting requirements is mandatory
- No minimum lot size — unlike NSW (450m²), Victoria has no minimum lot size for a small second home, though lots under 300m² may require a VicSmart fast-track assessment
- Anyone can occupy — no family-only restriction. Granny flats can be rented to anyone on the open market
- No car parking required — a deliberate policy choice to reduce construction costs and encourage alternative transport use
- No reticulated natural gas — all small second homes must be all-electric, supporting Victoria’s transition to renewable energy
- Cannot be subdivided — the granny flat must remain on the same title as the primary dwelling
These reforms make Victoria the easiest state in Australia to build a granny flat — no council planning delays, no lot size minimums, and no parking requirements.

When Do You Still Need a Planning Permit?
Even if your granny flat is under 60m², a planning permit is required if your property is affected by any of the following overlays:
- Heritage Overlay (HO) — properties in heritage precincts or with individually listed heritage buildings
- Bushfire Management Overlay (BMO) — properties in bushfire-prone areas (common in the Dandenongs, Mornington Peninsula, Yarra Valley)
- Land Subject to Inundation Overlay (LSIO) — flood-prone areas
- Environmental Significance Overlay (ESO) — areas with specific environmental values
- Design and Development Overlay (DDO) — areas with specific design or height controls
- Specific Controls Overlay — properties with existing specific planning controls
Check your property on VicPlan (planning.vic.gov.au/vicplan) before starting your project. If your lot has no overlays, you can proceed with just a building permit.
Setback and Siting Requirements
For small second homes in Victoria that don’t need a planning permit, standard building permit siting requirements apply:
- Front setback: Minimum 4m from front boundary (or align with existing dwelling)
- Side setback: Minimum 1m from side boundaries (may vary by council and zone)
- Rear setback: Minimum 4m from rear boundary (may be reduced for smaller lots)
- Height: Maximum 8m to ridge (single storey only, or 9m with roof pitch >25 degrees)
- Private open space: Minimum 40m² of private open space for the main dwelling (combined with granny flat)
- Solar access: New dwelling must not overshadow neighbouring north-facing windows beyond acceptable limits
- Overlooking: Must manage overlooking of neighbouring private open space and habitable room windows
If your design doesn’t meet standard siting requirements, you may need Report and Consent from the council or relevant authority before the building permit can be issued.

Compared to building a traditional brick granny flat in Victoria ($180,000-$280,000), the container option saves 70-80%. And unlike traditional construction — which requires a planning permit for most builds over 60m² — the container solution fits neatly under Victoria’s permit-exempt threshold.
Step-by-Step Approval Process
- Check VicPlan: Verify your property has no overlay triggers. If clear, proceed without planning permit

Victoria vs NSW: Which State is Better for Granny Flats?
| Factor | Victoria | New South Wales |
|---|---|---|
| Planning permit | Not required (in most cases) | Not required (CDC pathway) |
| Minimum lot size | None | 450m² |
| Maximum size (permit-free) | 60m² | 60m² |
| Car parking required | No | 1 space |
| Gas allowed | No (all-electric) | Yes |
| Approval body | Building Surveyor | Private Certifying Authority |
| Approval time | 10-15 business days | 10-20 business days |
| Rental restriction | None | None |
| Landed cost (60m² container) | $35,920-$52,030 | $35,850-$52,450 |
Bottom line: Victoria has simpler rules (no lot size minimum, no parking, all-electric mandate), while NSW has a slightly more established CDC system. Both states are excellent markets for container granny flats.
Case Study: Container Granny Flat in Outer Melbourne
A homeowner in Werribee (Melbourne’s outer west) wanted to build a granny flat on their 500m² block to generate passive income. They chose a HuaYing 20ft expandable container house with 2BR/1BA layout. Total project cost: AUD $43,500 all-in. Building permit was obtained in 12 business days with no planning permit required. The granny flat is now tenanted at AUD $380/week — generating AUD $19,760/year. The owner’s mortgage on the main house is AUD $520/week; the granny flat covers 73% of it. The project took 14 weeks from initial site assessment to final occupation certificate.
Frequently Asked Questions
Do I need a planning permit for a granny flat in Victoria in 2026?
In most cases, no. Since Amendment VC253 (December 2023), small second homes under 60m² in residential and rural zones without overlay controls do not require a planning permit. A building permit is always required.
What is the maximum size for a granny flat in Victoria without a planning permit?
60m² gross floor area. Granny flats larger than 60m² require a full planning permit application through the standard council process.
Is there a minimum lot size for a granny flat in Victoria?
No. Victoria has no minimum lot size for a small second home. Lots under 300m² may require a VicSmart fast-track assessment instead of the standard building permit process.
Can I rent my granny flat to a non-family member?
Yes. Victoria’s regulations explicitly allow anyone to occupy or rent a small second home — no family connection required. Standard residential tenancy laws apply.
Does a granny flat need a car parking space in Victoria?
No. Small second homes in Victoria are exempt from car parking requirements — a deliberate policy choice to reduce costs.
Can I use natural gas in my Victorian granny flat?
No. All small second homes must be all-electric — no connection to reticulated natural gas is permitted. This supports Victoria’s renewable energy transition.
What energy rating does a granny flat need in Victoria?
Minimum 7-star NatHERS energy rating. This is higher than the national 6-star standard and requires proper insulation, double-glazed windows, and efficient design — all standard in HuaYing expandable container houses.
Can a container house be used as a granny flat in Victoria?
Yes. Expandable container houses are ideal for Victorian granny flats. They meet the 60m² size limit, comply with 7-star NatHERS with proper insulation, and can be crane-installed in tight backyard access. All-electric design is standard.
How much does it cost to build a granny flat in Victoria?
A complete container granny flat from HuaYing costs AUD $35,920-$52,030 all-in (landed Melbourne including FOB, freight, GST, installation, and approvals). Traditional brick construction costs $180,000-$280,000.
Does a granny flat increase property value in Victoria?
Yes. A well-designed, legally approved granny flat typically increases a Victorian property’s value by $120,000-$200,000 — significantly more than the $35k-$52k build cost. Properties with granny flats consistently sell faster and at a premium.
