GRANNY FLATS IN VICTORIA CAN NOW BE UP TO 80 m²
Victoria has raised the maximum size of a small second dwelling (granny flat) from 60 m² to 80 m². Amendment VC306 came into effect on 15 October 2026.
- 33% more room: up to 80 m², enough for a genuine two-bedroom layout.
- Measured to the outside of the walls. Attached verandahs, decks, porches and pergolas don’t count towards the 80 m².
- No planning permit in most cases, and the planning requirement for an access pathway has been removed.
- Still the same: one per lot, on the same title as the main home, no reticulated gas, and a building permit is always required.
The 80 m² limit is in the planning rules; the building regulations are being updated to match. Your building surveyor will confirm what applies to your site. Source: Planning Victoria.

Planning Permit
A planning permit is a legal document that allows a certain use or development to occur on a particular parcel of land, issued by your local council. However, under Victoria’s small second dwelling rules, updated on 15 October 2026, most granny flats no longer need one.
No Planning Permit Needed for Most Granny Flats, Now up to 80 Square Metres
Victoria’s small second dwelling rules let you build a granny flat of up to 80 square metres (up from 60 square metres since 15 October 2026) on the same lot as your home, without a planning permit in most cases. Attached verandahs and decks don’t count towards the 80 square metres, the planning requirement for an access pathway has been removed, and the granny flat can be rented out. A building permit is always required.
Building Permit
Even without a planning permit, you will always need a building permit to complete your project. A building permit generally relates only to the construction aspects of a particular building or development.
A building permit shows that your approved plans and specifications comply with building regulations, allowing building work to commence. This permit can be obtained from a registered private or local council building surveyor, who will advise if either an occupancy permit or a certificate of final inspection is required upon completion of the building work.
A registered building surveyor is authorised to:
- Assess building permit applications for compliance with the Building Act 1993, Building Regulations 2018 and National Construction Code.
- Issue building and occupancy permits, and certificates of final inspection.
- Conduct building inspections at the mandatory notification stages.
give directions to fix for non-compliant building work. - Serve building notices and orders.
